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?
