Question MSI X670E ACE C5 ERROR Multiple sets of RAM

[djwadnjkanwda]

HI I have this strange issue with my PC at the moment where I seem to have broken two different sets of RAM timeline below.

Motherboard: MSI X670E ACE
RAM: GSkill F5-6000-J3040G32GX2-TZ5NR

The first set worked fine on boot, later I enabled the DOCP profile and game boostand saved and restarted the PC. This worked fne for a day but then the next morning when I turned it on I got a C5 error.
I figured this was a fault in the RAM (after some reading) and swapped it out for an identical set (since I was building two of the same PC). Clear CMOS, install RAM and this worked fine again.
I later enabled DOCP again and similar game boost changes like last time which worked fine for a few days. I come back a few days later and I had an A6 code this time. I removed all my USB devices (including bootable USBs) and reset the BIOS now I have a C5 code once again for the second set of memory.

• I've tried using one stick, two sticks, different lanes, etc
• I've tried flashing with the latest BIOS
• I've tried clearing the CMOS by the button on the back

I remember when I enabled these changes to the BIOS there was a green warning messaged on boot after saving. I can't recall what this said something about OC (unsure if useful).
I can't seem to clear this C6 error perhaps this is an issue with my motherboard now that I should look into RMAing?


Thanks in advance for any help.

When I use one stick of RAM in DIMMA2 I immediatley get C5 error
when I have both DIMMA2 and DIMMB2 populated it stays code 15 for much longer and then eventually goes C5 error.

In a two stick set I should be able to just use one fine is this correct?
Seems like by bios requires there to be two sets?

Managed to get PC to boot with one single stick of ram

When I swap the rest into the same DIMM they all get the same C5 error
