I updated to F20a with a 10th gen and I have no issues, Z490 ITX variant flashed via bios with file on usb.

If you check a CPU-Z Readings, you probably noticed that f20a version of bios have older date, than f8a, and is a f3 version to be honest, but little modified.

Did you enable Above 4G Decoding in the BIOS? I had to do this on my Z390 to get the Resize bar option to appear.

First I went to F20a (mostr recent official) and got a dead board. No post or anything. Had to remove CPU and every component to reflash to F7c which is also crap.

F20a bricked my Z490 Ultra too. I RMAd mine... didn't know F20a was the problem. Didn't think to flash back down to an early version
I'm running F8a now which has resizable BAR support. I didn't change any settings to enable it though.
That said, going from F3 with XMP to F8a without XMP enabled got me a higher 3Dmark score. F8a with XMP enabled got me 10137 vs F3 at 9967 (i7-10700KF GTX1080ti)
So there's definitely some performance benefits there. I'd share the results, but UL seems to have let a security cert expire and it's not validating my runs...

I can't get gigabyte warranty service to respond to an RMA. Keep getting an error message saying 'server error. Please try again later. I have been trying since last November. Anyone else have this problem?

You hook the fans to the CPU header... Should be fine. I have a X73 and works fine on my Pro Wifi

ricks22: Seems all AMD based motherboards of Gigabyte suffer from the same issue. Has 3 of them, AB350 Gaming 3, X470 Aorus Gaming Ultra and a X570 Aorus Ultra. None of them is hitting the rated XMP values of the memory. *

I have A B550 Pro, Rev 1, with the latest BIOS. I installed G Skill Trident Z Neo. 3600. Turning on XMP, does get me to almost 3600. Level 2 and Level 3 XMP have no effect. Any ideas about what my problem is? I will download the Ryzen DRAM calculator!

Fixed by a Win reinstall to UEFI. Old install was non-UEFI and I guess this was causing the problem. Still since F11 was working this proves there might be an issue with no-UEFI installs on F20 and F30.

Hi. I got a X570 Aorus Elite. Everyone figured out how to fix MB not turning off on shutdown/Restart if BIOS is grater then F11? I tried all F2x/F3x, same behavior. Even reset btn stops working, so I have to keep Pwr btn pressed 10 sec. Thanks in advance :
