e6300 o/c strange voltages

Hi there, am in the process of overclocking my new system and have got it stable at 3.050 in a quick orthos test (see below).

However i have noticed a decrease in voltage when the cpu is loaded as opposed to idle:

Also, the voltage that CPU-Z gives is different to the one i have set in the BIOS (about 1.39 i think). When changing the voltage the original default voltage is below the new voltage but greyed out, is this normal.

Sys Spec:
E6300, Gigabyte DS3, Geil PC800 Ultra Low Latency 2GB kit, Sapphire X1950pro.

Cheers very much

That's vdroop - a lot of motherboards suffer from it, some more than others. You may also find that the vcore you set in bios isn't the same as what you get. On my EVGA 680i, I have 1.55 set but underneath it tells me the actual is 1.51. I think you just need to be aware of this. It doesn't look like yours has much vdroop so I wouldn't worry.

Yep thats vdroop for you. I wouldnt be worried about it, as a lot of boards suffer from it to one degree or another, my asus p5n-e is terrible for it but I have a stable overclock at the same level as yours so will let it be.

Cheers very much for your replies.

It just seems a bit weird that no matter what i set in the BIOS, it doesnt change the voltage detected in CPU-Z.

Also, are there any programs that monitor the voltages accurately, as i have used google and the only one i found was HWINFO, and on that it reports my +12V line as 2.86:

The only way you are gooing to get accurate voltage readings is by using a volt meter
