UPDATE!! changing this does make temps not accurate see end of post
Stumbled on this, pretty crazy actually, Z270 and Kabby lake for sure have this not sure on others yet
heres the breakdown with temp graphs for different CPU PLL OC voltages or in my BIOS(gigabyte) VCCPLL OC
https://communities.intel.com/thread/112262
Soo my personal test is on Z270 gigabyte gaming 5 itx board
my 7700k I OC'd to 4.8 at who knows what voltage. Im set to normal and -.065v offset in bios and LLC on normal. In HWINFO64 shows VCORE from 1.26-1.308V under load durring AIDA64
Anyway on AIDA64 with cpu/FPU(hottest I can get) I was getting 81C.
I only change VCCPLL OC in bios from AUTO(shows 1.25V) to 1.15V and now max is 76C. I could instantly tell this was working as I ran something that normally would keep my cpu fan 100% but now it was throttling the fan
My idle temps are down as well(22-23C), almost to ambient(21-22C), but mine underclocks to .7v and 1.7ghz
Does not affect stability
So the question is what is the correct voltage to calibrate the temp sensors? Currently I think mine are a tad low at 1.15
mine defaults to 1.25v, seems others are different and enabling XMP may change it also(havent tested mine)
Update: So I took matters into my own hands. disconnected all of my fans and CPU fan. Ran aida64 for heat. results are that Yes changing the voltage makes the temps Not Accurate!
1st test was 1.21v VCCPLL OC 1st pic. It throttled at 99c
2nd test was 1.13v VCCPLL OC 2nd pic, now the temps are lower but it still throttled at 96C
So my boards default of 1.25v is likely correct(can only adjust odd voltages anyway 1.21,1.23,1.25 ect)
I know everyone was hoping for it to be a solution to the high temps of Kabby Lake
