Wierd vcore/cpu volt readings on multiple programs

post #1 of 7
Thread Starter 
Hi guys,

Been using this forum to help guide me with my OC's happy so far, though iv got a problem, i will attach an image of CPU-Z HWMonitor readings from my volates below. I'm using a 2600k on a GB P67A-UD3R-B3 Iv managed to get stabled at 4.5Ghz using 1.35 Volts a clock ratio of 45x here are my Bios settings;
Load Line Calibration enabled (If i turn this off i end up getting BSODS)
Vcore 1.35
QPI/VTT 1.1
CPU PLL over voltage enabled
Every other setting is on AUTO
C1E disabled
EIST disabled
CPU Thermal Monitor disabled
C3/C6 disabled

Iv managed to get 10 hours of stability using prime95, the thing is even though i have set my voltage to 1.35 in BIOS the readings in CPU-Z and HWMonitor show otherwise if anyone has any ideas i would appreciate it.



CPU-Z is showing 1.104 Voltage
HWMonitor showing VCore A at 1.49 voltage going upto 1.5v during prime95
Core temp showing 1.366v

If LLC is enabled, it is turning down your VCORE under load. CPU-Z is most likely showing the current voltage correctly.

I am puzzled why the other software is showing something different.

Lets try an experiment. Disable LLC, and set your OC settings to something stable (like stock). Run Prime 95 again. Are all 3 programs showing the same number with LLC disabled? That might give us some hints about what is really going on.

Vdroop is what lowers the voltage under load. LLC compensates for that, by raising load voltage.

im currently stable at 4.Ghz, 1.35 volts for cpu in BIOS CPU PLL Overvaultage/Load Line Calibration Enabled(Which really does stabalize the machine with it turned off i do witness alot of BSODs during Prime95) everything else on auto except for the C1E,THermal Monitor,Eist,C3C6 Disabled

this is the readings i get in OCCT/CPU-Z



really appreciate the help guys

As vonnis said.......
more explanation
Load Line Calibration is a function all most every MB manufacturer using to dealt with vdroop. if you leave it auto or enable it will manage your vdroop directly according to load on cpu. but if you desable llc you will notice vdroop under load stress of your cpu. so just leave it auto and manualy set your vcore. you will notice vcore hike under load that is normal....thumb.gif

software readings can be a bit off sometimes,
and what cpu-z shows is not vcore, but VID smile.gif

You have it backwards - CPU-Z shows Vcore, CoreTemp and RealTemp show VID.
