CPU Cooling problems: Just like 95C is normal for Ryzen, 100C is normal for Intel CPUs in many workloads. If you're worried about CPU temperatures, please look at reviews for the laptop or CPU cooler you're using.

Unstable 14900kf under high load (alien.top)

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?

What cooling solution are you using, and what temperatures are you reaching?

[–] [email protected] 1 points 10 months ago (4 children)

Ek nucleus 360. Temps are fine.when underclocked, I had it down to 60c under load and it still crashes.

Probably not enough vcore, even with undervolt cinebench at 60c is really too good to be true for those i9 at stock clocks.
