You should be able to access advanced motherboard peripheral settings (I think that's the title) by pressing ctrl+f1 while in BIOS. This will give you access to voltage settings, memory timings, etc. Hope this helps.
CPU-Z and sysoft sandra will both read voltage settings if I remember correctly.
BUT voltages are controllable but only upward +0.05, + 0.10 +0.15 +0.20 and so on. I can't seem to lower the voltages.that is were the problem lies as i want to lower them all to their minimum so i can oc to 3.2Gh safely.
