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?

    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.

      Glad to hear you made some progress! Weird that reaching a certain power limit causes the system to crash though… Makes me wonder if your PSU is faulty if your temps are good. Honestly, it may also be worth checking the pins on your motherboard. Ensure none of the pins are bent.
