This right here. Bad ram. The benchmarks are rarely as memory intensive as games. That’s why your benches run fine but games fail. Run one stick at a time. If both sticks return errors by themselves, it’s a motherboard or cpu issue.
I refreshed bios to the latest version (Ram compatibility fix, thought it might help). With XMP turned on, it didn’t post at all. I disabled any OC settings in AI tweaker, kept only one stick in the 0 slot. Memtest passed; it ran for an hour in the same game without crashes, will try again and insert another stick. Now I’m even more puzzled—why did XMP cause this issue? When I bought the PC, my first step was configuring XMP in BIOS, but I forgot for eight months. After the BIOS update, it started rebooting randomly, and now with the bios update, it doesn’t post with XMP enabled...
XMP boosts the memory clock speed. Any sign of instability will soon become a problem. The setup could be faulty on those chips—things can go wrong in many ways. You might manually adjust the same settings as XMP and get stable results. With DDR5, memory problems are much more common than before. Ideally, use RAM that matches your Intel architecture, and vice versa. You have the right type of RAM, but it may not work well with XMP. Also, place the RAM in slots 2 and 4 from the CPU (A2 & B2).
I'm going to ask my friend for a RAM check to rule out MB as the problem. Last night I played a few hours with one stick, added another, and there were no reboots. It's running at 4000MHz. If enabling XMP or adjusting any settings causes it to fail completely, that might help. The Memtest passes with both sticks. CMOS cleared fine. On the older BIOS versions it should work if XMP is enabled, but I'm wondering if downgrading the BIOS would be necessary. There are several versions between what I had and the one I installed yesterday.
