Asus Z690 ProArt Creators Wifi / i9-12900KS / 128GB DDR5 RAM - Bios crashes on DRAM (orange light), BIOS can only post in safe mode


Jul 6, 2022
Hello folks!

On a totally new machine, I am stuck on ASUS BIOS safe mode boot, shortly after installing Windows and using the computer for few days. Unfortunatelly I let ASUS AI Tweaker to do its run, and it seems it messed something and now I can only boot manually the drive with Windows, after a BIOS post in safe mode... it is SO annoying... also because it takes SO LONG to turn on the computer and stucks on the Asus mobo "postcode" orange light which is the RAM..

I am using:
CPU: Intel i9-12900KS
MOBO: ASUS Z690 ProArt Creators Wifi
RAM: 4x 32GB DDR5 Corsair Dominator 5200 MHz C40
GPU: Asus NVIDIA GeForce GTX 1070 ti
Drives: 2x Samsung SSD 980 PRO NVMe M2 2TB + Samung SSD 860 EVO 1TB
PSU: Corsair AX1600i
BIOS version: 1505

[according to the official ASUS website, all these pieces are compatible with the mobo]

After the BIOS posts in safemode, it launches the ram at 3600MHz.

My FAILED attempts to solve the issue:

1. Put default option in BIOS (F5).
2. Reset CMOS via shorting pins (as indicated in the user guide).
3. Uninstalling Asus AISuite.
4. Setting all DRAM BIOS options to AUTO.
5. Setting BIOS AI mode to "normal".
6. Update BIOS and the drivers to the very last versions.

But none of these worked!!!

My hope was to kinda find a way to reset the AI Tweaking intervention the BIOS, but I was not able to find it.

I have a strong feeling that if I could set the BIOS in a way it avoids getting stuckduring the booting, I'll solve the problem. Before having the issue, the computer was booting normally in few seconds (I am using Samsung 980 PRO NVMe).

What do you suggest me to do to solve this problem?

Thank you very much!

3600 mhz is the default DDR5 speed supported by Alder Lake, with 4 dual rank sticks of RAM. Currently, there are no single rank 32GB DDR5 ram sticks. They are all dual rank. So, that is why your motherboard is defaulting down to 3600mhz.

There may be a problem with 1 or more sticks of your RAM. Try booting the computer with only 1 stick of RAM at a time.

I have 2x16GB of Kingston Fury Beast DDR5 5600mhz. When I first got it, two different motherboards (MSI and Asrock) would take almost 2 minutes to post. And then I had sound glitches and A LOT of stuttering in Elden Ring. And video streaming apps like Amazon Prime, would freeze after a few seconds.

I returned the RAM to Amazon and got a new set of the same RAM. Everything works great, now.

That's an awful lot to ask of the memory controller which isn't particularly strong when it is populated with that much RAM in that configuration. I'd guess that you just have a weak IMC.
