Hi guys

Can you help me?

I have an Oc stable, 4.0 no Ht with Rampage II Extreme, but i need to use a lot of vcore to get it, 1,318, and i have a D0

I just tried everything, increase cpu pll, , qpi/dram...... but no sucess, i only can be stable with this vcore and without ht, if someone could help me i`ll be very happy:

Psu: Corsair 1000 Watts

Memory: Corsais Xms3 1600 XMP 9 9 9 24
