sandybridge voltage issues

post #1 of 3
Thread Starter 
I set 1.55v in BIOS because...

When I get into OS it reports 1.53v during idle BUT...

Under load (and required to be stable), it changes down to 1.51v...

Which means, I can be stable at 1.51v BUT I have to set BIOS to a scary 1.55v

Anyway to fix this?

I have LLC and CPU PLL both enabled.

I thought vCore was suppose to go a lil higher under load, not even LOWER.

some extreme forms of LLC like on the asus board can in fact raise vcore during load, but i dont see it as prefered as you can over voltage your chip that way. Its alot easier to raise it in BIOS and compensate for vdroop. (which is what you are experiencing.)

Typically you will experience vdroop meaning yes its normal for voltage to decrease under load and not the opposite.

go by what you see in CPU-Z not the Bios setting. voltage regulation is unfortunately not exact, but it can be predictable.

What temps are you seeing at that vcore?

77C Max.

Which is fine for me on AIR.

I never see over 60C in real world performance.
