VCCIO and system agent voltage

Hey, I am running an overlocked system on my Z-370F motherboard with the 8700K @ 5.2 GHz
together with 4 sticks of G.Skill OC'd @ 34000MHz

My CPU core voltage is set to 1.420 - however, I have no idea what values to run on my
"VCCIO" and "system agent voltage" and how to know if my current settings are right or wrong.
Right now my CPU VCCIO is at 1.05000 and CPU system agent is at 1.07500

I am also running two 1080Ti's in SLI if this has any importance to it.

BIOS is latest version.

Regards,
Rippin

Those sound perfectly healthy to me....you can always try lowering them and testing, of course, but I'm not sure I'd bother...

I'm at 1.10 for 3466, do you think I can go lower on those two settings?

Those are great values. I'd leave them be if your system is stable. 1.2v and below is good. Normally we the defaults way up at 1.3-1.4 so you're doing good.

My vccio and vcssa are on 1.125 actually it wasn't stable but all is stable when on AUTO .. Should I leave on Auto or 1.2 or will it be to high and cause some heat?
