Vcore Bios Setting lower than Vcore CPU-Z & Bios Readings

post #1 of 8
Thread Starter 
At stock 3.2ghz with the vcore set at 1.38 in the bios, I'm currently at 1.391v as I type. Why is this happening?

If I OC to 3.8 ghz (upping the multiplier), setting the vcore to 1.43v in the bios, then monitor at idle in windows, its 1.45v. When I run Prime95 or OCCT the voltage sits at 1.47v... ???

Shouldn't it dropping instead of rising from idle and load?


Cheers,

Jyk

Sometimes CPUz doesn't always get the correct values, but I've only had that affect me once or twice. Does your motherboard have LLC (load line calibration) and is it enabled? If you want to know more about LLC:

Also, just a heads up it's GHz not MHz

Lol - It was late when I was typing, thanks

As for LLC, i'll go check. And as for the values in cpu-z it happens consistantly. CPU-Z, Speedfan and ASrock OC Tuner are all reading the same values.

Do you have the EIST and Speedstepping disabled? No idea why it would matter but it may

Thats normal with boards that have LLC to extreme like my Asus P67 Pro and EVGA X58. Same deal here and its ok. I bet if you can actualy measure your vcore at the board it will be somewhere in between idle and load vcore readings from what CPUZ says.

don't know - I thought that was a intel only thing.

I hope so.

In the Bios the LLC setting are: Auto, Normal, Slight, and Off.
  • When I put the vcore on auto at default 3.2ghz the voltage setting in the bios reads 1.43v (Which seems high for 3.2)
  • I changed the vcore down to 1.373, and left LLC on auto, then ran Prime95 for 5 mins no problem (idle vcore was 1.39, load 1.41v).
  • Then I left the vcore at 1.373, and changed LLC to slight, then ran Prime95 _ computer rebooted....(idle vcore was 1.376, load 1.392v)?

What happened?
