Slot B RAM non détecté - TRX40 Aorus

Solved

Hello,

Following the receipt of my new workstation, I've been stuck for 2 days on the RAM installation. I think I've tried almost all the solutions suggested on different forums but nothing changes my problem. I'm posting here in hopes of finding a final solution before returning everything!

I am trying to install 256GB of RAM (8x32GB) Kingston Fury RGB on a TRX40 Aorus Pro Wifi motherboard with an Amd Threadripper 3970X.

The issue is as follows: The RAM modules installed in slots B1 and B2 of the motherboard are not recognized..


I have of course tried switching the RAM modules around, all of them work but I have never had any detection on slots B.

I then updated the BIOS to its latest version. I did several resets and cleared the CMOS. I changed the displayed frequency from 2400MHz to 3600MHz, which matches the RAM modules. I increased the voltage from 1.2 to 1.35. I tried several XMP profiles.

I disassembled the two modules from slots B1 and B2 several times, blowing them with compressed air and cleaning them with alcohol multiple times, but the issue remains unchanged.

I also conducted several tests on the RAM installation like this:

- 1 module in A2: OK
- 2 modules in A2-B2: B2 not recognized
- 4 modules in D2-C2-A2-B2: B2 not recognized
- 6 modules in D2-D1-C2-A2-B1-B2: B1 and B2 not recognized

And we arrive at my configuration of 8 modules with only B1 and B2 not recognized.

However! The RGB RAM lights up, and CPUZ indicates 256GB of RAM.

I think the slots are probably not dead, especially since I just unpacked the motherboard and plugged in the RAM (new) and visually everything seems fine, no residue or bent pin.

Here are some images of my BIOS.





I believe I haven't forgotten anything.

Thank you in advance for your help!

Configuration: Windows / Chrome 95.0.4638.54

    Hello

    And do two modules in the affected slots B1/B2 ????? work? Because if so, no problem

    For me, it's the BIOS display that is erroneous, but hardware-wise it is functional since CPUZ sees them and it directly queries the registry layer, so the BIOS directly.

    Unless when you only put two modules on the motherboard (in B) it doesn't work at all

    Thank you for your response.

    I tried installing only the RAM sticks in slots B1 and B2. The PC does not boot. The RAM lights up, but the boot is stuck at the RAM check..

    However, while CPUZ recognizes the 256GB, Windows only accounts for 192GB. It also indicates 2400MHz when they are actually 3600 (modified in the BIOS)



    I also saw a small message that appears for half a second during boot. I managed to read it by filming the screen.
    "Memory PMU Training error at socket 0 channel 3 DIMM 0 & DIMM 1"

    I will investigate this further.

      If none of the RAM works alone in slots B, a warranty claim needs to be made on the motherboard.
