Oh ok are 4 and 6 your favoured cores? I just say because I had a 13700k and core 5 and 7 were allways hotter. Then I got a 14900k and same again 5 and 7 hotter both by like 7c or so . But what I noticed is core 5 and 7 are the two favored cores on both my cpus. And even in multi core workloads those two allways get hotter. I think because they are the favourites they get work sent to them first and don’t get as much of a break.

Not sure if there is a way you can disable favoured cores I haven’t really looked into it yet.

Just out of curiosity is it core 5 and 7 that are higher?

Lies.

I’m running a 14900k on a MSI Z790 Tomahawk 13th gen board XMP 7200 mhz . All running good 👍 You just have to update to the latest bios.

Set XMP then manually change the frequency to 6400mhz. If all good just keep going up in frequency untill it either crashes then drop it back or you hit 7200mhz

Yes.

I would go the 13900k seems they have better memory controlers so far so you could go with 7200mhz memory and not have to worry about XMP working.
