Confused About vcore

post #1 of 10
Thread Starter 
I've set my vcore to around 1.332v in the BIOS, yet CPU-Z reads 1.296v at <1% load. HWMon reads 1.30v, BIOS says 1.316v.

My question is, which voltage should I assume my i5-760 actually running at? Is it a problem that the motherboard isn't actually giving the stated vcore?

When I further overclock this thing, I'm hoping to stick under 1.365vcore which is why this is a bit of an annoyance. My power supply is about a year old 700W OCZ - not a low quality PSU so-to-speak.

Thanks!

The bios voltage is the one you should go by. When you view your voltage from within your OS using an app, it will appear lower.

The voltage that most people refer to is the voltage in their bios. So if you want to say "I got blah speed at blah vcore" it would be your BIOS vcore.

The BIOS reading says 1.316v,
the actual vcore is set to 1.3375v,
CPU-Z says 1.296v.

Ah this is so confusing. ._.

Anyone got any ideas on which one to trust? Like I said, I'd prefer to stick under 1.36v meaning I'd have to set the vcore to 1.4v (0.04v bias) if it isn't accurately setting it. :/

Your CPU is experiencing vDroop. It is normal and happens with all CPUs. If you want it to stop enable LLC.

No, not at 0%, at load. Do you have your power saving settings on? (C1/C2/C3 ect.)

Disable that in BIOS, should keep your vcore to what you set it in BIOS.
