M2N32-SLI Dlx and Vcore problem?

[Spirer]

Hi guys,

I have a M2N32-SLI Deluxe Wireless, recently I upgraded the BIOS to 1603, because of the HTT x1 bug in 1503.

I started to OC my box now and while everything works fine, there is a huge difference between the Vcore set in BIOS and the Vcore read in AI Booster or CPU-Z.

This gap is something like 0.2V, which is a lot really. I have readings of 1.344V in CPU-Z and AI Booster (1.34V), when BIOS is set to 1.25V.

Anyone knows why this is and what I can do about it?

If that's really vdroop, it's a lot. vdroop will screw up your overclocks.

But I'd trust the bios readout rather than cpuz/ai booster.

My mistake it's not 0.2V, it's around 0.04V to 0.09V.

Basically, for each 2 steps I increase in the BIOS, it does one increase in CPU-Z, where it also reads much higher, like BIOS 1.250V, CPU-Z 1.344V.

Not sure if this might be because I'm using 1603, maybe I'll try an older BIOS version.
