I've been using XMP settings without issue for years, but now my PC crashes randomly during gaming. I've tested my RAM running in dual channel at 3200 MHz, but underclocking to 3000 MHz and 2900 MHz hasn't solved the problem. I haven't tried running it at base speeds (2667 MHz), but I suspect that would be stable. Each RAM stick has passed tests individually at 3000 MHz, and the slots checked out fine too. It seems like dual channel with XMP just isn't working. I've also tried using different slot combinations, but nothing helps. Could this be a motherboard issue? I've had it for 5 years. My specs are G Skill Ripjaw DDR4 3200 (2x16GB), AMD 5700X3D, and Asrock B450M Pro4.

It might be an issue with the RAM being faulty, an unstable memory controller, or even just dirty contacts. Try reseating the RAM several times in their slots, and consider cleaning the contacts with some solvent. You might also want to reseat the CPU if you haven't touched it in a while. Do you have any friends with spare RAM you could borrow for testing?
Have you updated your BIOS recently? Sometimes, updates can fix stability issues like this. Also, could you check what AGESA version you're currently on? Just trying to troubleshoot here!
I just updated to the latest Asrock BIOS version 10.43, which includes the AGESA ComboAM4v2 1.2.0.F.

Unfortunately, I can't borrow RAM from anyone at the moment. Should I still re-seat the CPU even if I haven't changed anything? Plus, can RAM really be going bad if it's only unstable in dual channel mode?
