Asus ROG Crosshair VIII Dark Hero and RAM issues (Solved)

Hardstyle
Level 8
Hello everyone,

I'am an hardcore gamer and I've always used to build my own computer.

Unfortunatly I realy need help with the latest config.

Here the stuff*:

Asus ROG crosshair 8 DARKHERO (with latest bios version 3801)
Windows 10 pro 64bit
AMD RYZEN 9 3950X
Watercooling Corsair H100i PRO XT
DDR4 3600 4x8 Corsair vengeance RGB PRO
Asus STRIX 3080
Double samsung NVMe
Corsair HX 1200W
Corsair Crystal 570X

There's two majors issues*:

1. The computer do not switch on normaly. Sometimes it turned on like normal, next time i have to press twice the power botton or sometime it doesn't turn on at all. I have to power off and on the supply power.
It's purly random. I've already turn off the fast windows boot in the bios.
PS*:There's no reset botton in the corsair 570X tower.

2. Crashes.
When I m playing there's crashs. It's always the same windows error*:
''Material problem*: LiveKernelEvent code*; 144 or ffab*''
Sometimes there's bluescreen sometimes it's just the game who shut down. Sometimes it's just a big freez but the game come back (in world of warcraft for exemple) but i still have the problem report when I check windows fiability historical.

3. The Qcod from motherboard show 0C witch means*: '"Reserved for Future AMI SEC Error Codes" Maybe its because i've overclocked my CPU to 49x. When i turn off overclock GPU it show 9E. Note that there's still crashs when the CPU is not overclocked.

I think the problem come from the RAM config.
LiveKernelEvent 144 say that's i need to test my RAM. My first RAM was diagnosticed with an error and I've just received the new ones from Corsair yesterday. No error from windows diagnostic and from Memtest86 test with the new one but I still have crashs issues.

I've tested everything, DOCP mode, manual config (just changing Ram frequency to 3600).
It seems that it's more stabble when the voltage of DDRRAM is boost at 1.36V.

When I choose the DOCP profil in bios i've a warning message ''the DOCP profil can occure instability, the max profil is around 3600''

Another thing that guide me to RAM config problem is when i go to ICUE software from corsair (this is where you can set up you'r RGB) after a crash there's a red exclamation mark in the RAM icon i can't select it. It's weird.

I fell very lost and frustrated to not use the computer normaly.
Is there someone abble to help me*?

Thank's a lot for reading me,

Wish you a good day

Just received new RAM. Made a big Apex legends session this morning with high load on GPU+CPU. Not a single crash and the game works better than the corsair RAM. The new ram is validate by AMD and Motherboard requirements

Now gonna check if there's still turn on issue...
Not fixed with SOC voltage config. I've reset in auto mode.

Hello,

What Q-Code is displayed on the motherboard LED?
13900KS / 8000 CAS36 / ROG APEX Z790 / ROG TUF RTX 4090

You changed RAM did you clear the BIOS.

Hello RedSector,
Yes ive cleared it. Do you think i need to change motherboard battery ?

If it's only happening when XMP/DOCP is enabled, try increasing DRAM voltage to 1.4 - 1.45v

IOD VDDG around 1 to 1.05 and CCD around 0.98 to 1.05. See if this helps.

Hello guys,
As i am desperate now. I've decided to unplug and replug all my setup.
On the DARKHERO 8' manual they said i need to plug watercooling on AIOPUMP but on the Watercooling Corsair H100i PRO XT they said CPUFAN.
I tried AIOPUMP but cant boot because error message from CPU cooling warning. That's weird.

I've reput CPU fan and did a clear Cmos and now the QCODE shows 9E witch means : '' Reserved for future AMI codes"

When i overclock the CPU the q code instantly shows OC or 0C

I never get AA...

I'm out of hope

I"ve read a guy from reddit who say that 0C means that a component cause issue with booting system. This is exactly my case !
