Hi guys,

on Cinebench 2024 I score only 85/86 points in single core mode for my 13900kf. Multicore also seems low, but not as drastically (if I interprete the result score as linear)

It’s stock (enabled XMP in the BIOS, that’s about it…)

The CPU doesn’t overheat, I’m watching tightly and core temperatures are way below…

What I do see and not get is… it seems that whatever calculations are going on there just don’t “fill up” the CPU core… and also it appears to be scheduling on an E-core often and maybe even getting switched around a lot. It’s really odd to me and I don’t follow how that would typically be handled. I searched reddit for suggestions, but mostly it’s bad cooling - but I’m not throttling - or the results are already way closer to target than what I see. Something is off, and I don’t know what. -> How to find that?

​

Thanks in advance :)

edit: additional info: prime95 seems to generate a 100% CPU core usage if I just run single thread tests.
