Here are your PC's specifications, excluding the temporary drives you've connected: https://pcpartpicker.com/list/3z9WYd

I started this setup in late 2020/early 2021 and have made several upgrades over time. Back when it ran on a 10700K, I turned on XMP and everything worked smoothly. Even after moving to a 11700K with XMP enabled, it stayed stable for more than a year. However, once I switched to a BIOS version that didn’t support XMP properly, the system would suddenly refuse to boot, showing an error about a detected failure.

I tried fixing it by re-seating the RAM, swapping the sticks, updating the BIOS, forcing a downgrade, and resetting all settings—nothing resolved the issue. I suspect this isn’t just a typical XMP overclock failure, but possibly a deeper problem.

Occasionally, it does boot with XMP enabled without issues. When that happens, I never face any problems while running in that mode. I’ve spent hours or even days testing RAM and stability, and everything passed without errors.

When it does boot with XMP, it seems to function well—sometimes for months before a reboot causes trouble. This pattern suggests something unusual is at play.

One odd observation is that whenever it boots with XMP enabled, it accepts the JDEC standard (2666) for DDR4 memory. Changing timings or clock speeds from the standard doesn’t help much. Even altering them to 2670 or 2660 causes the same error. This strongly hints that the system isn’t simply failing due to an overclock, but rather encounters a bug related to memory compatibility.

I’m considering upgrading my RAM soon, hoping it will resolve the issue, but the current market conditions make that unlikely. I’m curious—does anyone think this might be a bug or something else? Any suggestions on what to try next?
