After recent update to windows I noticed that my CPU core speeds drops down on couple of cores, now I never had this problem before as I turned off setepdown future in bios, all my cores should run around 4.3, also check power management, I'm not expert but why is this happening now.
I have been running prime95 to load all the cores and you can see when stress testing all cores running at 3.2-3.3 which is the base CPU speed, stop the stress and everything back at 4.3? is this normal? I am under the impression that the i7-8700 should run on all cores at 4.3
I think this is something to do with voltage and power, as you load the CPU will run all cores @4.3 for a while and after 30sec will gradually start to slow down, give min and all will be run at @3.3, vrm throttling? again all this is recent, use to be able to run all on 4.3 with out any drops.
