Help reducing VDrop(CPU VCore Voltage)

post #1 of 4
Thread Starter 
I'm running a BFG nForce 680i SLI motherboard. I did the pencil mod and now I have 0.0V difference while idle and under load(1.248V Idle--1.248V Load). I just can't figure out how to reduce my VDrop. My VCore in bios is set at 1.26875V and bios reads the VCore voltage as being 1.24V. CPUZ reports 1.248V while idle and under load. Doing the pencil mod for VDroop seemed to help with the VDrop a little, but how can I further reduce this VDrop? Thanks!

That is not vdroop.

Vdroop is the difference between idle and load and you have already fixed that.

The reason that the you select 1.487 for example, and yet everything reads 1.485, is just because the physical components are producing a slightly lower voltage. It could also be that the sensors arent 100% accurate.

So you really do not need to worry about this difference, just because there is nothing you can do about it, its just the way it is.

Ok, so obviously I've completely gotten rid of my VDroop. I noticed a little less of a VDrop, but that can't be corrected so that CPUZ reads the VCore as the same I input into bios?

I ran into the same problem. Don't worry about it, and just stay under 1.36v in cpu-z, not bios.
