My issue is with the QVL for RAM. I've had 2 - 2x16 GB Corsair Vengeance running. Now it slipped my mind about the speed when I did the build. So recently I saw I wasn't running at full 6000MHz for the ram and was only doing 4800MHz, so I checked the RAM for configuration, updated, then enabled XMP, had issuess, updated the bios and icue firmware, plugin, and rebooted. No go.
No matter the configuration it just didn't work. so I disabled XMP ran the 4 as I had been. Looked up on the QVL, saw 4x 16 GB CORSAIR CMH64GX5M4B5600C36 on the list. Got it, installed it, and ran it. Worked for about 1 day. Applications start crashing. Did MEMTEST86, 1st DIMM is bad. Ok. A bit mad at this point. No big deal. Lets doing something different. I really start digging in about RAM, the QVL, etc. Socket Support (1, 2, 4), ok...So, I do a search. 4 Sticks, Socket Support 4, nothing else. I get nothing. (pics related). I look at CMH64GX5M4B5600C36 on the list, only socket support is 1, 2.
Ok. so please tell me what the heck I'm supposed to do here. If I look at the 2 stick kits some have 4 socket support but no support for any 4 stick kits? Is the socket support a real thing? If the MB is good up to 128 GB RAM, but no 4 stick support for 4 sockets, how can it be good up to 128GB? Am I missing something when I enable XMP? Am I supposed to do something else?
I mean what am I supposed to go off here? 4x___GB? or 4 Slot Support? I have literally never had this much of an issue with RAM and I've been building and fixing PCs for years.
How am I supposed to put in a 4 stick config? Is it the Red X config or is it the Purple X config?

Hello @Tormaim
Thank you for reaching out to us.
Could you please confirm if your current BIOS version is updated to the latest version, 2801, released on December 6, 2024? Are they accompanied by a BSOD or an automatic restart when the crashes occur?
If you are installing four RAM modules, clearing CMOS, and making no manual BIOS adjustments (including enabling XMP), does the crashing issue persist?
Similarly, if you install two modules in the recommended DIMM_A2 and DIMM_B2 slots, clear CMOS, and refrain from any manual configuration, do you notice any differences in system stability?
To help us better understand your hardware configuration and usage scenarios, could you kindly provide the following details using the template below?
- a photo of the CMH64GX5M4B5600C36 module's specification label, including the part number and production batch
- an image of the BIOS main page
- the brand, model, and installation slots or ports for your GPU, SSD/HDD, and PSU
- the OS version and OS build number
- a description of the circumstances and frequency of the crashes
- a detailed video recording the issue, including the memory installed slots, system behavior under BIOS default settings and whether a crash occurs, the usage scenario, crash conditions, and frequency when XMP I is enabled, and the system temperature at the time of the crash
We appreciate your cooperation and look forward to your response.
Thank you.
