Hi all,

Decided to go for undervolting of my 10900k to start doing my bit to reduce the electricity bill . So far I've reached the below valuez:

Bios vcore: 1.16v
Offset: - 0.020v
VCCIO: 1.10v
VCCA: 1.10v
LLC: 4
RAM: 32GB @ 3700mhz 16 -16 -38 1.32v

CPU is set to stock for ratios
Cache ratio: 47

Cinibench underload vcore 1.057v.
BF 2042 underload: 1.011v to 1.175V

Are these good values?

Looks good if its 100% stable. Never had my similar 10850k that low, but might give it a try.

I can do the same for my 10700kf. Sits around 1.16v under full load (4.7ghz) and under 0.9v when under 2ghz which is where I sit my cpu at under low load using throttlestop. Having it sit at 2ghz instead of 800mhz stops my cpu from jumping up and down from 800mhz idle to full speed when running a game that uses little cpu. This allows low cpu utilizing games from jumping up to 4.7ghz and remains at 2ghz helping save a little more from constant boosting up and down.

Well i settled for 5GHZ all core at the same voltage. in Cinibench it sits at 1.1v.

Cache Ratio had to come down to 46 for 100% stability.

Everything else stayed the same

Wish i could do that. can't go below 1.25v at 5ghz. Hell, i have to drop to 4.6ghz for 1.1v. you sure 5ghz is stable at 1.1v 24/7? If so what setting you got?

i got lucky with my 10900k, SP103.

Below is a video i had taken before I undervolted/underclocked
