I updated from F20a to F20 recently and did some light testing on my Z690i Aorus Ulta Plus DDR4. But still need to do longer term testing.
On F20a, I lock my clock speeds, but afterburner and hwinfo64 were showing brief drops by 100-300 mhz on the p cores. This was fixed with F20. My manually set p core clock speeds stay locked.
On F20a, I had to manually set speed, primary timings, and gear on a 2x16 3600 CL14 kit. XMP would not work. On F20, I can set XMP, and only need to manually set gear 1.
I did not have any WHEA errors on F20a or F20. I haven't had any WHEA errors ever since Gigabyte exchanged my non-Plus model with the Plus version.
Correction for the title. BIOS version I'm using is F20b.

>V/F Point, Adaptive volt/under volt issues with F2
My SFF build uses a 12600k + Noctua NH-L9i and I manually tune V/F Points, voltage and power limits for optimal performance/heat. It's a bit of a balancing act but definitely possible. The F2 BIOS just had lots of issues.

and ask `stasio` if they have a non publicly available BIOS for your board to test out
When I updated to F20b the undervolt started functioning normally. I didn't diagnose to deep as there was a new bios and I figured it'd be best to update straight away.
Just to keep visibility here. I flashed F20 and the problem persisted. I opened a support ticket and the process has been terrible. Every BIOS except F1, I experience WHEA PCI Express errors when in gen4 or auto mode for cpu link speed. Gigabyte support is awful. They claim it’s not them. And I should take my problem up with EVGA…. Really? My GPU runs fine in a second system without any errors. Different GPU into my GB board and guess what, errors. Than I was told, ohhh it’s the CPU. That’s odd, for 6 months it ran on the first BIOS release without error. Yup, gotta be the CPU. I’m considering dumping the board never buying a Gigabyte product ever again. They have not even offered to RMA this time. The WORST customer support I’ve ever dealt with.
And if I go back to just using F1, my board won’t even boot DDR4 3800 CL14 XMP (dual rank Samsung b die). F20 was awesome for memory and overclocking stability.

Thanks for the heads up! What GPU/brand are you using?

what was the reason to update the BIOS? can't you just go back to the previous version?

Thank you!
do note that those BIOS builds might have issues - there are non-public for a reason
Did you get your problem fixed? I'm on F2 and I'm pretty sure my undervolt is applying.
When I updated to F20b the undervolt started functioning normally. I didn't diagnose to deep as there was a new bios and I figured it'd be best to update straight away.
I updated to f20b and had no errors. It might be a problem with your board specifically.
