Vcore automatically raising itself?

[Gixer]

I've been trying to lower my Vcore voltage to help keep temps as low as possible on my overclocked i7 930.

I've set it at 1.34375 in Bios yet when stress testing with Intel Burn according to CPU-z vcore raises itself to 1.396v. It raised itself to exactly the same voltage when bios was set to 1.35v.

I am using an Asus Rampage II mobo. Is there a setting I'm missing which means it wont change from what I set it to in Bios or is this normal for the above to happen?

Cheers
Paul

Thanks Stan, I'll take a look when I get home later. Still learning what all the settings do in Bios on this board.

I dont have HT enabled as I found it pushed my temps up to high when using intel burn. All my games are playing smoothly, including FSX with settings pretty much maxxed, so don't think its really worth the extra heat.

I'm just thinking along the lines that I've set it at 1.35v and its upping it to almost 1.4v which is higher than I'd like it to be going and will also cause more heat.

Wish I had a 930 D0 that required low Vcore to hit 4.2Ghz. Anything lower than 1.35v and intel burn causes a BSOD. I'm running 22/191 at the moment though to achieve 4.2Ghz. I'm going to try 21/200 over the weekend, maybe this will help with voltages? I'm also hoping changing to the 21/200 will mean I can set my DRAM at 1600Mhz instead of the 1532Mhz its currently at.
