Disabling some cpu cores

[ToughestDiabeticAthlete]

I have the 3700x, and if its possible to disable some cores, can you then increase the clock speed without any issues running stable?

the boost allready handles this. disabling cores really wont do much if any. 

you can however enable PBO which removes the powerlimit. 

 

 

there is also ccx overclocking, but im assuming that is not what you are interested in.

Just looked up ccx and, if its gonna give higher oc speeds, then I'm all for it

well a Zen 2 CPU has 2-3 dies where 1-2 are core-dies. 

 

inside each is 2 CCXs. the 3700x having 1 die and 2 CCXs in that die. 

 

Ryzen master shows which cores is within each CCX and which are the best cores. each CCX is up to 4 cores. 

 

you might get lucky to have 4 cores managing to run at 4,3ghz and the second set of 4 cores running at 4,2. maybe more or less on each CCX depending on the quality of the silicon, and if you have a decent VRM. 

 

keep in mind to not exceed 1,4v core voltage and i very much suggest keeping it a 1,375 ish and below. (edit: Zen 2 is new enough on 7nm that we do not know the degrading territory well.)

Thanks for the info
