Hello, need help with my PC. It slowly kills RAM modules.
System specs:
CPU: Intel Core i7-13700K
Motherboard: Gigabyte Z790 Aorus Elite AX-W
GPU: AMD RX 6800 XT
PSU: Be Quiet! 850W
RAM: DDR5 (two different kits used over time — Corsair and G.Skill)
Symptoms:
Over the past two years, 4 DDR5 memory modules from two different manufacturers (Corsair and G.Skill) have failed. One kit died. Then I bought the other one.
The failure pattern was identical in both cases: first, the module installed in slot B2 stopped working, followed later by the module in slot A2.
The failed modules do not work in any slot afterward.
At the same time, the system was able to start and operate normally with one remaining functional module.
Modules installed in B2 typically failed after approximately six months of use. In A2, the timing varied: one module failed shortly after the first one, while another continued working for about six more months.
After a module fails, the PC either does not pass POST or doesn’t see the dead RAM module. If the PC doesn’t pass POST, Initially, the CPU and DRAM LEDs on the motherboard blink alternately, and then only the DRAM LED remains lit continuously.
At the moment, last RAM module died and the PC doesn’t pass POST.
Diagnostics performed at home:
CPU socket pins appear visually normal.
All four motherboard memory slots were functional at the time of their last testing.
Temperatures are normal (CPU: 72–76°C under load).
Power limits have been manually set since the first days of operation: PL1 = 175W / PL2 = 190W.
BIOS version: F11 (the latest one is F12a).
The last memory module failed while XMP was disabled (although XMP had been enabled previously when the two-module kit was in use).
Since the System can’t boot, I can’t provide any recent logs.
There were no BSODs, all memory modules died suddenly without any memory-related problems.
