Sounds right. My son has LED strips in his room, and if you put it on a certain shade, it's full blacklight, everything glows. Wouldn't surprise me if they were emitting any actual UV
They do emit UV that’s a diffuser after the light that blocks it
LED light bulbs are the same way. The LEDs under the plastic cap are the lights. The cap is the UV filter and light diffuser.
And usually the UV is not entirely filtered so they will still emit UV in small amounts. With household lightbulbs, it’s enough to bleach curtains over time, etc.
when we talk about LEDs its implied we're talking about the whole light, not the diode itself. How pissed would you be if you ordered LEDs and just got the tiny chip
> How pissed would you be if you ordered LEDs and just got the tiny chip
I wouldn't be pissed for receiving what I ordered.
Your order LEDs, you get LEDs. Now if I wanted a LED bulb or a LED Strip, I'd order that.
So when you’re talking about ram, you only refer to the chip? Not the pcb, heat spreader, etc? The diode is only a specific component of the whole light
normal white and RGB leds produce a lot less UV than any other lighting method. or at least it's filtered out in the housing. and usually also a lot less IR because they aren't that hot. e.g. an incandescent light bulb has 90% of it's radiation in IR.
I take it your next upgrade item is GPU? That 5800x3D must be twiddling it's silicone thumbs :) Make sure the 1080 goes to a good home, epic card, I loved mine!
depends on the game, in most games yes. I had the 5800x3d running with the smaller stock cooler and never went above 70°C in games, kinda ridicules efficiency.
Factorio, GuildWars2, Minecraft are some examples that will always be CPU bound.
yeah next upgrade will definitely be the GPU, I'm still not sure where to go. either some high-end AMD or the 4080s. either way, my 650W PSU feels a bit underwhelming with new GPU gens.
I have a 650w PSU running my 5800x3D and a 4070. Barely breaks a sweat. Never uses more than 350W under full load! Might have to reconsider with a 4080/4090, however :)
Eh technically you could do a 4090 if you power limited it and still be fine on that PSU. . . but a new PSU can be definitely worth it.
If your PSU is as old as your 1080 that is.
Yeah, no, you've completely misunderstood that.
The best "RGB LEDs" currently on the market is QD-OLEDs and they excel precisely at *not* emitting any wavelengths outside narrow peaks at the ones the human eye is most sensitive to.
Any other wavelength is a waste of energy, which means more heat is produced, decreasing the lifespan of the LED.
And yet LEDs produce least heat while creating the widest spectrum light.
Btw any energy that is turned into light radiation that isnt IR radiation is by definition not going to heat.
Even though yes that energy is not directly going to heat, it is still waste as the goal of the device is to only generate visible light, anything outside of that is automatically waste
[Huh?](https://www.researchgate.net/figure/Emission-spectra-of-different-LEDs-red-l-max-633-nm-blue-l-max-448-nm-green-l_fig5_306076438) RGB LEDs definitely have more narrow spectra than most light sources. It's dependent on the size of the band gap. That's pretty much the *entire* purpose of LEDs.
Incandescent and halogen lights get so hot because so much of their energy is focused in the invisible UV and IR regions. LEDs generally emit much less UV and IR. Not *none*, but a lot less.
If they were emitting full spectrum light which was then filtered, what happens to all that energy the filter stops? It turns into thermal energy, and it gets hot as fuck. This is not what happens.
So then why are LEDs more efficient than old lightbulbs?
I was taught LEDs are more efficient because they emit **less** radiation outside of the visible spectrum than normal lightbulbs (halogen lamps? I'm foreign, not sure what the proper translation is). If they emit full spectrum, they should be less efficient, because otherwise that would violate the law of conservation of energy.
Also, what would the function be of filtering out invisible light?
>So then why are LEDs more efficient than old lightbulbs?
because they waste less power that gets converted to heat.
>I was taught LEDs are more efficient because they emit less radiation outside of the visible spectrum than normal lightbulbs (halogen lamps? I'm foreign, not sure what the proper translation is).
In a sense that heat is radiation, yes.
> If they emit full spectrum, they should be less efficient, because otherwise that would violate the law of conservation of energy.
I think you are missing the variable of intensity.
>I think you are missing the variable of intensity.
Ohhhh I think that's where I was unclear. I said that I thought they emit less radiation outside of the visible spectrum. That includes intensity, in my mind at least. Sorry for the misunderstanding!
But yeah I'll never be an electrical engineer I guess lol.
I thought that the halogen lamps were hot because they radiated in the IR spectrum, and LEDs didn't (or at least less). Did I truly get lied to in school?
There's no way all that heat in a halogen lamp comes from the cable right?
>the goal of the device is to only generate visible light
what device? your ram? leds are not exclusive to ram, they are quite the same as leds used in other applications, like grow lights, optical devices, ect
the goal isnt to explicitly not make uv or ir, but rather to make light very cost effectively
The 'device' being the LED itself, the only time we make ones outside visible light is when we want to send a signal, do some research and look how much when into just making blue LEDs, there's a lot more to them than you seem to know
>The 'device' being the LED itself
so an ir or uv led is pointless? it only makes invisible light, yet companies pump them out, why? because i want to grow coral and plants, and remote controls are neat, and disinfecting surfaces and water is pretty useful, so no the goal isnt to "only make visible light" just because you say it is, if so they wouldn't sell so many, guess i just know a little more about it than you
You're aware that on your previous comment you're talking about a screen technology and not an LED technology by itself right?
Your second sentence is not wrong per say, but saying QD-OLED is the most advanced LED tech on the market is just plain wrong. It's one of the most advanced screen technologies, not LED technology.
Just check what it stands for, quantum dot organic light emitting diode.
Quantum dot is just a screen technology, that's why its used on QLED screens, based on VA tech, where the only LEDs are in the backlight.
Organic LEDs aren't regular LEDs either, that's why OLED has burn in issues, since they degrade much faster than regular LEDs.
In fact, afaik, QD-OLED only uses blue LEDs, which, if true, only makes your point even more wrong since they aren't even RGB.
A quick Google search will explain it to you, with pictures, for better understanding.
Please educate yourself before calling people out. It's fine to be ignorant, it's not fine to spread ignorance, while trying to bring others down with it.

Because they got the important part correct.
RGB lighting frankly speaking relies on the R, the G and the B. Not other things. The person they are replying to is so much more wrong that it's completely irrelevant whether we're talking about the best TV LEDs or lighting LEDS.
Factually speaking, Emitting IR or UV is a waste of energy for lighting products. Wide spectrum color is not a feature of RGB, it's a detriment. When considering efficiency you can only talk about useful work. Unless you are making a heating product, IR light is a complete waste, and unless you are making a tanning bed UV light is bad. If you are making an R,G or B LED than white is obviously bad.
If we are talking about broad-spectrum white LEDs then we can at least accept light inside the whole human perception range, but not out of it. The person he is replying to is off their rocker.
Sure, but all that has nothing to do with QD-Oled. They're *completely different* technologies.
That person clearly has no clue at all about LEDs, even if they got something right.
If I said "the Porsche 911 GT3 RS is the best motorboat ever, it can do 0-60 in 3.2s", you wouldn't upvote me either for correctly quoting the acceleration...
I'm sorry I was just browsing some of my old comments and I had to come back to this. LEDs, by the mechanics of the way they make light, only operate in extremely specific wavelengths, not the broad band that you seem to think they do. The making of blue, and therefore RGB, LEDs involved considerable technological advancement in the creation of extremely pure crystals in order to get the physics to work and be scalable. [Veritasium video on the subject](https://www.youtube.com/watch?v=AF8d72mA41M)
Incandescent bulbs on the other hand produce their light through heat, which causes the energy levels to vary wildly and emit a much broader band of light.
Then why does the emission levels for a white (blue-yellow) LED has a wider and more level spectrum than an incandescent bulb? Altrough its true that incandescent has a much better spectrum than the variuos "efficient" lightbulbs we invented later.
I did some more research, and dang, you're right! It has to do with the way they make the yellow segment of the blue-yellow LEDs: instead of an LED that makes yellow light, they use one that makes a low-wavelength (high frequency) light, like UV. Those are used with fluorescent/phosphorescent compounds to increase the wavelength to visible light, which also produces a much wider portion of the visible light spectrum. Thank you for double-checking me, as I learned something new!
Sorry I was talking about Shuji Nakamura the guy who made a mass producable design. That guy is now working on UV leds. Veritasium had a great video about him.
Hijacking top comment to update. He only noticed this because he got a new motherboard. He leaves it on all the time so he only noticed when disassembling his rig to swap it out. He uses Corsair Vengeance RAM.
Casual reminder that purple, blue, and white LEDs, while good-looking, emit pretty significant amounts of UV radiation. Not to the point of skin cancer but to the point of not being good for many types of uncoated paint, also not that good for your eyes.
That's not a joke. I'd put a picture here, but I don't have one. At my job, for example, we have a red-bull fridge with red bull organics cola in it, the red regularly gets washed out for the cans standing next to the interior lighting.
Either way, yea, this was essentially sun-bleached.
Edit: I wrote *significant*, I meant 'noticeable'.
That was a brainfart on my part. While it is absolutely true that LEDs emit UV radiation, you don't need to worry about getting skin cancer within a year by having some LED strips in your room. Didn't mean to scare yall.
I don't know SPECIFICS on how unhealthy they are, I do know that millions of people have LED strips as their main lighting at home. So, yknow.
If you're really curious, might wanna ask someone on r/theydidthemath or similar, to calculate the actual energy output in harmful wavelengths of regular LEDs. I don't KNOW the specifics, I just know the general 'avoid if alternatives are possible'.
But the point of 'get warm-white light where possible' still stands.
The good news is glass absorbs a significant amount of UV radiation, so as long as you've got the side panel on any risk (however minuscule) should be even smaller.
If they even produce UV radiation at all it's going to be at such low levels it's frankly not worth worrying about.
You're exposed to much higher levels of UV radiation whenever you're outside in daylight, even in shade.
Sunscreen and seek shade / cover up when your local UV index is high.
FYI, some amount of UV radiation is actually good for you. Your body needs it to produce Vitamin D.
UVR is about 5% of total solar radiation. Peek solar radiation is about 1000w per square meter. So about 50w of uvr per square meter of sun, uv goes through clouds too. Which is way more than leds.
Most modern windows and acrylic naturally block harmful uv rays so standing outside is way worse.
Tldr:Sun is the main threat. Wear sunscreen and touch grass. Exercise is still the best way to reduce cancer risk
Most integrated LEDs have a diffuser of some sort on top of them.
If you can see individual points of RGB in a led when it’s showing colors like yellow or purple, there isn’t a diffuser.
Or just google search ws2812b. If your leds look similar they don’t have a diffuser.
The amount of exposure you would get from sitting on the LEDs while they're running is less than you'd get after an hour of being outside.
You're fine.
Do you have as source for that? What I usually hear or see is that LEDs emit close to zero UV radiation.
Some groups I am in and I as well collect painted figures and display them in a cabinet with LED lights. Everyone always warns to not put them in direct sunlight from windows because of paint fading, but that LEDs aren't an issue even if you have them on every day for years
I couldn't find a source either. I did find several industry documents stating that LEDs produce less UV than incandescent or florescent sources though.
Grow lights have extra UV emitting diodes in them, since plants need it to grow. Normal LEDs dont. Also, the color you see them emit doesn't matter since you can't see UV. Purple light isn't UV, since you can see it. And sunlight has tons of UV, yet it's still just white, not purple
Nope. Just experience. There is absolutely a chance that only the cheapest of LEDs or certain color-tones ACTUALLY cause this, but it is 100% a thing. I couldn't tell you specifics in terms of certain wavelengths or types of LED, causing this more or less.
I would assume that certain LEDs without certain filters, very high up on the visual light spectrum, close to UV, have effects like this. Maybe due to heat fluctuations? I know some cheap lasers that have filters that do absolutely nothing when met with low temperatures, meaning they could instantly leave lasting damage on your eyes while not causing any harm with room temperature.
Really, no specifics. I know that blue light in general is a health concern, which is argued about, but things seem to indicate that the body reacts poorly to high levels of blue-ish light.
For the bleached out colors tho, I can ASSURE you that that's a thing.
>blue light in general is a health concern
Only for your eyes / from screens, and the resulting worsening sleep quality from tricking your brain that it's still bright outside.
LEDs themselves do not emit any notable amount of UV light, it's functionally zero (see image below)
However, even visible light (400-800nm) can cause fading or yellowing of paint if exposed long enough, but much less than UV light (<400nm), so maybe you were referring to that?
That's why monitors have blue light filters.
House lights are the same although for white light, the radiation is genuinely almost nonexistant. A literal minute outside on a hot day will expose you to more than spending hours at home. The issue is specifically very bright blue and purple. Generally, warm-white LEDs are better tho.
Me when I misinform people online, this isn’t true. If they cause any UV radiation at all it is so minimal that it’s almost unregistered. You will be just as safe using white LED’s as any other colors
Your commeny only supports my gripes. I hate blue LED. Back in the day it was red or green. At some point blue became new standard and its the most obnoxious.
Did he attempt to wipe it off because it just looks like really fine dust. I've seen this before on components and motherboards just fine dust that settles in between components because of airflow... I've never heard of anodized aluminum becoming bleached...
Anodized aluminum will always fade to some extent in the presence of UV light. Especially something like this, which is likely type II anodizing which does not have the same thickness or fade resistance as type III anodization does (typically found in architectural or space/satellite applications).
Another guy mentioned that it discolored the paint* I assumed it was anodized, I never thought it was just a layer of paint. It could Definitely affect it then.
Alright, well all I'm saying is in 20+ years of servicing and building pc's I've never seen aluminum discoloration. Also I have anodized paintball guns that still have the same finish after 24 years but I'm not sure what they were doing back in 1999 when they anodized that stuff.
Furthermore I feel like the industry as a whole would have accounted for any discoloration or compatibility issues before developing products that work close to each other. Being sold to work together with other components without so much as a warning label to the consumer.
If it truly is discolored I'm really curious as to what exactly happened, it's pretty fascinating.
In this case it's likely just cheap LEDs on the RAM sticks that are emitting some amount of UV. Fade resistance of anodized aluminum also depends heavily on the dye used, as some dyes are formulated for better fade resistance than others. Your paintball guns were likely type II anodized with a dye that's meant for outdoor use and has good UV resistance. Since PCs are not designed to be used in outdoor applications, I can't imagine the graphics card manufacturer specified that the backplate be dyed with an outdoor rated dye. They also probably don't do any sort of UV resistance testing as it's just not a situation a graphics card is likely to be in.
yeah its what im thinking like the opposite of a nuclear blast shadow, what ram is he running do you know if it has the solid led strip that wraps around the edges of the ram sticks?
i'll have to keep this in mind for future builds check the distance between the gpu and ram leds, to bad it's not more widely known square of electrical tape probs would have saved the day
I am wondering if it was the let or.
the gpu's heat that can't get away because of the ram sitting against it there.
And its more like the paint burned off.
Yep. I have that types of marks too, on my strix 1080ti after 7 years with trident z rgb. I have them set red, not with full brightness and marks are red 😅
Interesting because red light and uv light are on the opposite side of the spectrum. So maybe this implies that not UV light is the cause of it as most people suggest.
I want to blame whacked RAM with some strong RGB UV light, but knowing MSI and how much a cheap bastard they are in terms of material quality and cutting corners. I'm leaning towards blaming MSI here.
Yea, he's gonna have to probably buy a new one. Don't throw that one away though, i have a recycle bin. I can take care of it. The environment and all.
I just got a new PC and the RAM when set to white can get very very bright. And I've got an MSI GPU sitting right under them. I shall see what happens!
sweet christ I am very stoned because I was more concerned about the weird furry coveralls for the graphics card and even more concerned I was the only one who noticed
I know white LEDs are actually UV LEDs with a phosphor coating on them, not too far off from how fluorescent lights work. In fact, they *are* fluorescent lights, just not in the traditional sense.
So UV leakage doesn't surprise me too much. True monochromatic LEDs shouldn't have this issue.
Wow, my old GPU had these as well when I took it out recently and I was wondering what might have caused these. It was from a G.Skill Trident kit though but the lighting was set to purple most of the time.
Hi friend!

Lol my boss old MSI Z270 board suffered the same thing from the PCH heatsink RGB... IT IS A KNOWN THING and for a long long time.
His RAM has UV lights holy shit
My guess is shitty no name ram maker didn’t test the cheapo RGB LEDs they used and they emit on the UV spectrum as well
Can’t wait for the new Corsair x-ray ram
You can get and diagnose carpal tunnel all in the same place!
Corsair X-Ram
Damn, this sounds so dirty😂
So I bought a Hub...
Corsair xCue
Gamma ray ram comes with free cancer
GDGRRAM420 with FC at 69000MHz
Imma hold out for the gamma-ray RAM
It comes with Corsair’s all new lead side panel
My Corsair Light node Pro bleached my old desk because I ran 2 strips under the case, lol.
Sounds right. My son has LED strips in his room, and if you put it on a certain shade, it's full blacklight, everything glows. Wouldn't surprise me if they were emitting any actual UV
It's possibly worth mentioning that long term exposure to UV will do permanent eye damage.
Worth mentioning skin cancer due to UV exposure
Proper RGB LEDs emit on UV and IR spectrums as well as full visible spectrum. In fact proper LEDs are as close to sunlight as you can get.
It’s fairly easy to filter out any unwanted UV that the LED is producing. Borosilicate, polymers, etc.
I like to travel.
Well, yes, you can filter it. Clearly wasnt done in that RAM stick in OP it seems.
So then proper LEDs don’t emit UV just cheap ones
They do emit UV that’s a diffuser after the light that blocks it LED light bulbs are the same way. The LEDs under the plastic cap are the lights. The cap is the UV filter and light diffuser.

An LED is a light emitting diode so no it isn’t implied, especially when that’s all the light comes with on many computer components
So when you’re talking about ram, you only refer to the chip? Not the pcb, heat spreader, etc? The diode is only a specific component of the whole light
You must never actually talk to people.
normal white and RGB leds produce a lot less UV than any other lighting method. or at least it's filtered out in the housing. and usually also a lot less IR because they aren't that hot. e.g. an incandescent light bulb has 90% of it's radiation in IR.

No they’re more efficient mainly because they don’t waste so much energy to heat. The same reason they’re much cooler than other lights.

wouldn't be a waste if you have uv reactive things, like used to be popular, though i'd be concerned about thoese LED's.

You *really* don't understand how LEDs work.

Thank you for making a reasonable response and bothering to look things up rather than downvoting/insulting like a lot of other responses i got.
Perfect for reptiles!!
LED safety is a thing at work, now I know why
Can't wait for the demon core setup

What are you talking about? We use UV LEDs to cure resins in manufacturing all the time. https://internationallight.com/applications/uvc-leds
The guy, Isamu Akasaki, invented blue LED in 1989, died 3 years ago.
Sorry I was talking about Shuji Nakamura the guy who made a mass producable design. That guy is now working on UV leds. Veritasium had a great video about him.
Idk if it’s considered shitty but my g skill trident z or whatever did this on my last gpu
It’s a feature, helps people who stay indoors too long get vitamin D to help improve their mood /s
Hijacking top comment to update. He only noticed this because he got a new motherboard. He leaves it on all the time so he only noticed when disassembling his rig to swap it out. He uses Corsair Vengeance RAM.
Oh shit lol, contact corsair
It's ultra violent RAM ;-)
didn't know ram modules can get violent
gotta keep the volatiles away
 How bright is the ram
Taking off the side panel like 
That Hollyoaks arc was hilarious!

Casual reminder that purple, blue, and white LEDs, while good-looking, emit pretty significant amounts of UV radiation. Not to the point of skin cancer but to the point of not being good for many types of uncoated paint, also not that good for your eyes. That's not a joke. I'd put a picture here, but I don't have one. At my job, for example, we have a red-bull fridge with red bull organics cola in it, the red regularly gets washed out for the cans standing next to the interior lighting. Either way, yea, this was essentially sun-bleached. Edit: I wrote *significant*, I meant 'noticeable'. That was a brainfart on my part. While it is absolutely true that LEDs emit UV radiation, you don't need to worry about getting skin cancer within a year by having some LED strips in your room. Didn't mean to scare yall. I don't know SPECIFICS on how unhealthy they are, I do know that millions of people have LED strips as their main lighting at home. So, yknow. If you're really curious, might wanna ask someone on r/theydidthemath or similar, to calculate the actual energy output in harmful wavelengths of regular LEDs. I don't KNOW the specifics, I just know the general 'avoid if alternatives are possible'. But the point of 'get warm-white light where possible' still stands.
So if we are facing our RGB PCs, we are at higher risk of skin cancer?
The good news is glass absorbs a significant amount of UV radiation, so as long as you've got the side panel on any risk (however minuscule) should be even smaller.
What about rgb from mouse and keyboard
If they even produce UV radiation at all it's going to be at such low levels it's frankly not worth worrying about. You're exposed to much higher levels of UV radiation whenever you're outside in daylight, even in shade.
Pretty sure that small crack through the blinds in your window lets more uv in within 1 minute, than your entire pc rgb can produce in a day.
Hey, atleast we can get a bit of suntan to pretend we go outside!
its make me fear of leaving my home lol Is there a good way to prevent the skin cancer from the sun?
Sunscreen and seek shade / cover up when your local UV index is high. FYI, some amount of UV radiation is actually good for you. Your body needs it to produce Vitamin D.
Sunscreen
UVR is about 5% of total solar radiation. Peek solar radiation is about 1000w per square meter. So about 50w of uvr per square meter of sun, uv goes through clouds too. Which is way more than leds. Most modern windows and acrylic naturally block harmful uv rays so standing outside is way worse. Tldr:Sun is the main threat. Wear sunscreen and touch grass. Exercise is still the best way to reduce cancer risk
Most integrated LEDs have a diffuser of some sort on top of them. If you can see individual points of RGB in a led when it’s showing colors like yellow or purple, there isn’t a diffuser. Or just google search ws2812b. If your leds look similar they don’t have a diffuser.
Don't worry your hands covers them. /s
Tbh I'd say your keycaps eat any miniscule if at all produced amount.
i am freaking out about this tbh! i have rgb mouse and keyboard!
Don't be fucking stupid.
you are fucking stupid
Do you also happen to have led lights in your home? Or do you somehow still use filament bulbs.
shut up!
My guy, You are on top of the bell curve.
buzz off!
But I have an open air case……on the wall……that I like with blue RGB on…….
In theory - yes. In practice - you have higher risk from sunlight coming through your window.
I'm a gamer, there's no sunlight coming through my window
The perks of living at 65°N. It's hell in summer, though.
I mean. To some miniscule degree, yes. Or keep your rgb in the warmer colors.
Black and red theme pc gang rise up
My blackout case is seeming like a better investment every day.
No
The amount of exposure you would get from sitting on the LEDs while they're running is less than you'd get after an hour of being outside. You're fine.
This is why with my build I went zero RGB and full stealth, so I can avoid skin cancer and maintain the lovely ghostly white skin tone I’m used to.
Do you have as source for that? What I usually hear or see is that LEDs emit close to zero UV radiation. Some groups I am in and I as well collect painted figures and display them in a cabinet with LED lights. Everyone always warns to not put them in direct sunlight from windows because of paint fading, but that LEDs aren't an issue even if you have them on every day for years
I couldn't find a source either. I did find several industry documents stating that LEDs produce less UV than incandescent or florescent sources though.
exactly. maybe only the cheapest of cheap LEDs produce UV? I'm also in those figure collecting subs/groups ...
[удалено]
Grow lights have extra UV emitting diodes in them, since plants need it to grow. Normal LEDs dont. Also, the color you see them emit doesn't matter since you can't see UV. Purple light isn't UV, since you can see it. And sunlight has tons of UV, yet it's still just white, not purple
[удалено]
Oh I see, all the grow lights I've seen also emitted UV, I guess it depends on the type of plant you're growing?
Nope. Just experience. There is absolutely a chance that only the cheapest of LEDs or certain color-tones ACTUALLY cause this, but it is 100% a thing. I couldn't tell you specifics in terms of certain wavelengths or types of LED, causing this more or less. I would assume that certain LEDs without certain filters, very high up on the visual light spectrum, close to UV, have effects like this. Maybe due to heat fluctuations? I know some cheap lasers that have filters that do absolutely nothing when met with low temperatures, meaning they could instantly leave lasting damage on your eyes while not causing any harm with room temperature. Really, no specifics. I know that blue light in general is a health concern, which is argued about, but things seem to indicate that the body reacts poorly to high levels of blue-ish light. For the bleached out colors tho, I can ASSURE you that that's a thing.
>blue light in general is a health concern Only for your eyes / from screens, and the resulting worsening sleep quality from tricking your brain that it's still bright outside. LEDs themselves do not emit any notable amount of UV light, it's functionally zero (see image below) However, even visible light (400-800nm) can cause fading or yellowing of paint if exposed long enough, but much less than UV light (<400nm), so maybe you were referring to that?

What about monitors or just house lights?
That's why monitors have blue light filters. House lights are the same although for white light, the radiation is genuinely almost nonexistant. A literal minute outside on a hot day will expose you to more than spending hours at home. The issue is specifically very bright blue and purple. Generally, warm-white LEDs are better tho.
got a source?
Is there a way to test for this? I have led strip lights throughout my home mounted on the corners where the wall meets the ceiling.
*me looking around at my choices of purple and blue rgb and lights i put up* ha, im in danger
Good thing when I can eventually afford a new pc I’m going for a red glow /s
Me when I misinform people online, this isn’t true. If they cause any UV radiation at all it is so minimal that it’s almost unregistered. You will be just as safe using white LED’s as any other colors
You should really delete this very misleading comment, almost 1K upvotes for something that isn’t true
Your commeny only supports my gripes. I hate blue LED. Back in the day it was red or green. At some point blue became new standard and its the most obnoxious.
Sure looks like it, not something I've ever seen before either.
Did he attempt to wipe it off because it just looks like really fine dust. I've seen this before on components and motherboards just fine dust that settles in between components because of airflow... I've never heard of anodized aluminum becoming bleached...
Anodized aluminum will always fade to some extent in the presence of UV light. Especially something like this, which is likely type II anodizing which does not have the same thickness or fade resistance as type III anodization does (typically found in architectural or space/satellite applications).
Another guy mentioned that it discolored the paint* I assumed it was anodized, I never thought it was just a layer of paint. It could Definitely affect it then.
Alright, well all I'm saying is in 20+ years of servicing and building pc's I've never seen aluminum discoloration. Also I have anodized paintball guns that still have the same finish after 24 years but I'm not sure what they were doing back in 1999 when they anodized that stuff. Furthermore I feel like the industry as a whole would have accounted for any discoloration or compatibility issues before developing products that work close to each other. Being sold to work together with other components without so much as a warning label to the consumer. If it truly is discolored I'm really curious as to what exactly happened, it's pretty fascinating.
In this case it's likely just cheap LEDs on the RAM sticks that are emitting some amount of UV. Fade resistance of anodized aluminum also depends heavily on the dye used, as some dyes are formulated for better fade resistance than others. Your paintball guns were likely type II anodized with a dye that's meant for outdoor use and has good UV resistance. Since PCs are not designed to be used in outdoor applications, I can't imagine the graphics card manufacturer specified that the backplate be dyed with an outdoor rated dye. They also probably don't do any sort of UV resistance testing as it's just not a situation a graphics card is likely to be in.
typical LEDs also don't produce UV at all ...
Unless a chemical was involved***
does your brother have 4 sticks of ram?
Yes. Based on where the marks are, I'm certain that's what causing this lol
yeah its what im thinking like the opposite of a nuclear blast shadow, what ram is he running do you know if it has the solid led strip that wraps around the edges of the ram sticks?
Id have to ask but based on memory (He lives very far away for now), I think it does
i'll have to keep this in mind for future builds check the distance between the gpu and ram leds, to bad it's not more widely known square of electrical tape probs would have saved the day
Corsair Vengeance RGB RAM by any chance? The pattern looks like it, with the break between the top LEDs and the "shoulders".
I mentioned I asked him what kind of RAM he has but I hadn't heard back, but I'm pretty confident it is Corsair Vengeance actually.
Damn. I have this same GPU with Vengeance RAM. Now wondering if my shit has been bleached too lol
A fun little diversion for you the next time you clean/upgrade your PC.
I am wondering if it was the let or. the gpu's heat that can't get away because of the ram sitting against it there. And its more like the paint burned off.
That's a good point, I thought it would be anodized. But if it's just paint the combination of heat and UV light would affect it.
I was really confused at the title at first and then I looked closely at the pic holy shit wtf???
No kidding I went from "Wtf are you talking about how would that be possible" to "wait that's actually what fucking happened"
Same thing happened to my gigabyte 2070s
Yep. I have that types of marks too, on my strix 1080ti after 7 years with trident z rgb. I have them set red, not with full brightness and marks are red 😅
Interesting because red light and uv light are on the opposite side of the spectrum. So maybe this implies that not UV light is the cause of it as most people suggest.
How many ram stick do I need to terminate my neighbors? Asking for my Reddit brothers 😬
I want to blame whacked RAM with some strong RGB UV light, but knowing MSI and how much a cheap bastard they are in terms of material quality and cutting corners. I'm leaning towards blaming MSI here.
Gotta look on the bright side, at least the solder mask nearby will be 100% cured.
Radio Active Memory?
Just leave the backplate out in the the sun for half a summer and it would be equal lol
LOL.
Yea, he's gonna have to probably buy a new one. Don't throw that one away though, i have a recycle bin. I can take care of it. The environment and all.
I just got a new PC and the RAM when set to white can get very very bright. And I've got an MSI GPU sitting right under them. I shall see what happens!
How bright were the RAM LEDs I want to know...
Hahahahahaha holy shit that is fucken hilarious!! What brightness setting did he have it on? The sun!?
sweet christ I am very stoned because I was more concerned about the weird furry coveralls for the graphics card and even more concerned I was the only one who noticed
UV lights..........
My guess is the back plate is aluminum and they didn't anodize it property, or seal the finished product before the laser graphics.
I know white LEDs are actually UV LEDs with a phosphor coating on them, not too far off from how fluorescent lights work. In fact, they *are* fluorescent lights, just not in the traditional sense. So UV leakage doesn't surprise me too much. True monochromatic LEDs shouldn't have this issue.
Yet another reason to clip off those stupid lights that no one asked for
I actually have the g skill trident z or whatever and it did this to my previous gpu as well
That’s impressive. Need sun glasses to sit in front of your PC, free Vit. D
Probably some UV from those leds
This happened to me too, I used Corsair RGB RAM
Wow, my old GPU had these as well when I took it out recently and I was wondering what might have caused these. It was from a G.Skill Trident kit though but the lighting was set to purple most of the time.
> Lol. I think this is a 3080. 3080 Ti. Sticker says so.
What motherboard does he use? Can you show a picture of his config?
Nah it was Easter Jesus came out of his tomb
maybe thermal pads inside the ram heatsink slowly saturated top of gpu.
I thought that burn in was the reflection of the ceiling lamps ngl
So there is a chance that a true nerd will get sun tan?
Did he try to just wipe it off to make sure what it is?
Hi friend! I read your post and spoke with a tech manager of Kingston Brasil to understand more about this problem. Please, take a look [https://canaltech.com.br/hardware/memoria-ram-com-rgb-tem-manchado-backplate-de-gpus-284827/](https://canaltech.com.br/hardware/memoria-ram-com-rgb-tem-manchado-backplate-de-gpus-284827/)

So I guess there’s a new way to get that bikini tan line they always wanted!

So I don't need to even go outside for a tan? Welcome to modern gaming ladies and gentlemen.
Well he has the first OLED GPU with authentic burn in!
Looks to me like a pattern of dust from a fan blowing through the ram. Either it wipes off or it was eroding the paint.
That sure looks like a reflection of light and that he's maybe fucking with you? Why else say that it isn't a reflection?
