Vcore shows different value everywhere?

post #1 of 4
Thread Starter 
Like topic, my vcore is different everywhere i look. In bios vcore is set to like 1.45v now and in bios h/w monitoring vcore shows up as 1.5v. And now in windows vcore shows up as 1.52 in cpuid monitoring and 1.51 in cpu-z and in core temp it says 1.41? *** wich one of those should i trust?
Ahh now when i ran Occt it says 1.5v?

Sounds like Vdroop (amount vcore changes under load vs. what it's set to in the BIOS). Also, do you have cool 'n quiet enabled? When you say that the vcore is set to "like" 1.45v, does that mean actually 1.45v? Or somewhere around 1.45v that you don't quite recall?

Does your motherboard have a "load line calibration" (LLC) setting? This is basically something that the motherboard tries to use to alleviate the vdroop problem.

I think CPU-Z is typically pretty accurate, though I don't understand why different programs read vcore differently. The only thing to factor in is what load state your CPU is in when you are measuring the vcore--because it changes at various times (despite a specific value set in the BIOS).

Probably just vdroop combined with measuring at various times. Make sure you're measuring under the same load conditions. Have you tried HWMonitor?

I'd load up Prime and run cpu-z and HWMonitor simultaneously and compare their readings. It's not uncommon for programs to read slightly different values. What's more important is that your vcore isn't fluctuating a lot.
