I recently assembled the following system:

MOBO: TRX40 AORUS PRO WIFI (1.0)

GPUs: 2x EVGA FTW3 ULTRA GAMING RTX 3090

CPU: Threadripper 3990x

OS: Ubuntu Server 20.04

RAM: Corsair CMK256GX4M8D3600C18

PSU: EVGA SuperNOVA 1600 T2

After several attempts now, if I turn on my system, I can log into my OS. But if from the OS itself I reboot, then the motherboard hangs. The only way I can debug what the mobo is doing is through 4 LEDs, which should light up sequentially, each indicating the corresponding component is checked and working: CPU -> DRAM -> VGA -> Boot. On the motherboard I can see that it hangs on DRAM LED. If then I force a shutdown through the power button, and power the system back on, than everything works fine. Also if I shutdown the system from OS, and then wake it up via the power button, it works fine. The only issue seems to be when I reboot. I tried clearing CMOS removing the small battery but does not solve this issue. Also tried a different type of memory stick. Also tried running the system with a single stick. None of this helped. Any suggestion? The only thing I can think of is a faulty mobo.

  • As long as people keep buying these motherboards, vendors will never bother to ship less buggy firmware.. put the RAM clocks to safe defaults and see if the problem persists. – anx Dec 05 '20 at 06:47
  • Sadly that's something I've already tested by disabling any XMP profiles. Do you think I should increase manually RAM timings? Anyway I've ordered an MSI TRX40 Pro 10G (which allows better debugging in any case) to see if I'm simply working with a defective MOBO. – M. Pari Dec 07 '20 at 10:22
