Offset voltage and how it works.

[danrey84]

I have a 7920x and it's always run rock solid at 4.8ghz all cores at 1.275v when I manually tuned it in. Now while I got some time of due to a broken leg I was wanting to sort off try my hand at offset voltages. Now I know when my CPu idles on the stock voltages it dropped down to 0. 801v within cpuz. I'll put my specs below and any help would be great. 

 

X299 apex

7920x 4.8ghz

32mb 3400mhz Ram 

1080Ti

1x250gb nvme (os) 

1x2tb nvme (games) 

 

Thanks again peeps

offset voltage is an offset value applied onto auto voltage. For example, the auto settings pumps 1.4V into the CPU at 4GHz, then a -0.12V offset will lead to the board trying to give 1.28V at 4GHz instead. This of course, does not take Vdroop into consideration.

So basically what I have to do now is leave my 4.8ghz oc applied and now set the voltage back to 'auto' see what that brings me upto on cpuz and then do the offset from whatever figure cpuz gives me when running at 4.8ghz??

is there "adaptive + offset" option?

Yes I have these option

Auto

Manual 

Adaptive 

Offset

The difference between offset and adaptive is that offset affects voltage from 0x (multiplier) all the way up to the max multiplier you set, but adaptive is like manual mode that only kicks in when the frequency exceeds the max stock frequency (4.4GHz for the 7920X), i.e. when the VID table (basis for auto voltage set by Intel for each CPU) ends. If you have "adaptive + offset" then you can avoid pumping unnecessarily high voltage at lower frequencies by setting offset first, then manually entering a voltage number (same stuff you do on manual). My board's too old to have this though so no hands-on experience
