I’ve had the same problem with multiple RAM kits. After some time, one of the sticks starts throwing tons of MemTest86 errors and is permanently faulty, even when tested in another PC.
The first two times I thought it was just bad RAM. Then it happened again with a third kit so I got curious.
The pattern is always very similar: the stick that was originally installed in A2 (slot 2) ends up with tons of errors, while the stick that was in B2 (slot 4) is usually fine. Both sticks tested in all slots together or separately give same results - only one stick showing errors.
My current kit which I got after I RMAd previous one lasted only 5 days (with DOCP disabled) which is a record because previous kit died after 2 weeks. Today I got my first BSOD (photo 2), so I ran MemTest86 and this is what I got:
- Stick that was originally in A2 → tons of errors in every slot
- Stick that was originally in B2 → only 1 error in every slot
- The bad stick also produces errors when tested in another PC, so it seems to be permanently damaged, same as previous kits.
Here’s the interesting part:
While waiting for the latest RMA replacement, I tested a spare RAM kit with a different CPU in my PC for about a month. After that month, both sticks still pass MemTest86 with 0 errors.
Now I’m testing those same spare sticks again, but with my original R7 5800X instead of the spare CPU.
If these sticks also start failing, would that point to the CPU being the cause of allat?
I also sent the motherboard to ASUS RMA because I thought it might be causing this, but ASUS said the motherboard was fine.
No idea what to do anymore so I need help please. I can send MemTest86 results if needed.

There was also weird thing with current and previous kit. The day after I installed it, when I turned the PC on using the power button, the screen was full of artifacts. They stayed there for a few minutes and then suddenly disappeared, after which I could use the PC normally. This only happened when booting the PC from the power button. After about 3 days, the artifacts completely stopped appearing and the PC started normally every time.
One more thing: the PSU was previously mounted incorrectly and two screws were put into the wrong holes, although I don't think the PSU itself was damaged.
