I recently put together an Unraid system with an Asus Prime B760M-A motherboard and 64GB of Crucial Pro DDR5 memory (4x16GB). Everything was running smoothly for months until a power outage caused a hard shutdown of my entire setup. After the UPS failure, my system started to lock up, so I conducted a series of tests. Initially, I ran Memtest86+, which failed with all 4 DIMMs installed together but passed when tested individually in every slot. I didn't overclock anything, just made some minimal BIOS adjustments while aiming for system stability. The system was fine for a long time prior to this issue. Since the incident, I've reflashed the USB drive, disabled Docker, and removed plugins without success. The only change from before the outage is that the power supply is now connected directly to the wall instead of through the UPS while I await a replacement. Has anyone experienced something similar or have any advice on what to try next?

When you mentioned that nothing is overclocked, what speed are your memory modules running at? Sometimes, XMP or EXPO settings can be considered overclocks and might introduce stability issues, especially if you're using all four slots. It’s something to think about.
I left XMP on "Auto" since there was no option to turn it off completely. I thought that would adjust settings automatically for me. But now that you mention it, I guess I should've been more cautious since it was working fine for months!
