I've big problems getting my UD7 B3/i7 2600k OC stable. I boot at x50 (no problem) but when I put some load on it (latest version of LinX) my Vcore drops from 1.53 to 1.45V, NOTICE that this is with LLC enable and at level 7. It dosent mather which frequency/LLC level it is, it still happends.

But with stock settings (optimized default) the vcore is deadly stable... Guess I'm missing something?

I'm monitoring with the latest version of EasyTune6 (HW monitor).

System specification:
i7 2600k
UD7 B3
A-DATA XPG+ 1866MHz CL8
Crucial C300 64GB
MSI N480GTX Lightning
Be-Quiet P8 1200w
