Question about Gigabyte Aorus Master z690

shura · Nov 9, 2022

If there's anyone using this motherboard, your input will be appreciated. Is it normal for these boards to go into a long (2-4 mins) procedure of some sort during the first boot after BIOS update? It just does stuff silently with nothing on screen, which I consider a bit nerve-wrecking.

Normal operation after, just this first boot and also (as of BIOS F20) the same silent thing on the first boot after I reenabled my DDR5 XMP profile.

Thanks!

It sounds like it's "working" on the changes you made. If all is well after, I wouldn't worry at all.

Sadly, the issue with inability to boot right after enabling XMP profile for Corsair DDR5 is not my impatience as of BIOS v20. After upgrading to v21, same thing: boots fine with XMP disabled, but as soon as it's enabled, infinite loop of codes including 54 and 5C. Very interestingly, a forced power down and restart escapes the loop and the machine boots normally. The last BIOS version that did not do this was v20b, which was since removed from the list of available BIOS versions for this motherboard.

Do you have more than one XMP profile? If so, try another.

How many memory sticks do you have? If 2 what slots?

Also, what is the exact model of memory?

Two sticks, only one XMP profile, memory model #CMK64GX5M2B5600C40, slots 2 and 4, CPU-Z shows timings in agreement with what the manufacturer wants (40-40-40-77). Everything runs fine once you do the trick with powering down the machine during that initialization loop -- no problem initializing during the boot after, hands over to OS without issues.

I am absolutely sure it's on the Gigabyte side -- enabling the XMP profile up until BIOS v20 was perfectly fine. In other words, this issue is only with the two latest BIOS updates (20 and 21).
If you look at the BIOS release notes here, they keep working on their compatibility with XMP profiles for various manufacturers and probably keep screwing up whatever was working before. Prior to BIOS v20, the beta version of v20 (20b -- currently removed from the list) was fine with my memory. Such BS...

I'm going with your assessment on the BIOS upgrade being the culprit.

Have you contacted Gigabyte?

Oh, yes. They act a bit funny when you are reporting a bug, not asking for help. That whole routine with with "have you tried reseating your sticks" and "leave only one stick" and my favorite "disable the xmp profile then," even though everything works fine after you get past their init bug and the whole motherboard is marketed around being able to safely use mfr's XMP profiles. :)
