10900k + z490-e rog strix Over problem!
 

I dont put stable at 5.1GHZ all core, with less than 1.33 llc6...
With cinebench r20 with 91c n some cores.

With a 850w xfx gold modular
1 stick of generic ram ( 8gb )
lian li galahad 360 AIO
( without gpu, dont have come yet )

Can i let this way? or is so much Vcore?
With settings i have do put in bios? do make better overclock?
Can i put Vcore manual to UV the cpu, but still taking intel performance? (5.3 on 2 core )?

Thanks!

your temps are more important than vcore. As long as your temps are fine it doesn't really matter with regards to voltage. Heat is the cpu killer not voltage.
