I have a 14900kf that is having some issues being stable while under large multithreaded workloads. For example, running r23 or compiling c++ code with all the threads used, it’ll crash every time within 6 minutes or so. If I use maybe 80% of the cores, it’s completely stable.

I’ve tried different ram, different PSU, underclocking, with and without XMP and doesn’t seem to matter.

Any ideas what else I can try?

    Ok, I would run a memory test first to see if it’s the memory. Then run a CPU test to see if it’s the CPU. Then adjust the voltage. What CPU voltage are you running currently? Bios update?

      After ~12 hours of stress testing, a bios reflash, and OS reinstall, it’s working great now. I don’t know exactly what the problem was, but I can now recreate it if I raise the Turbo Power Limit. Even numbers as low as 270watts (with good temperatures) will cause it to crash exactly like i described in my original post.
