Syvere, that's a tough board to overclock the quads on. Take the nb sink off and put some good TIM in there and then use a small fan on the sink after. If you have some small sinks for the mosfets use them. Sometimes I just use old sb sinks and cut them into tiny bits to use for mosfet sinks on cheap boards. How much are your fsb and mch overvoltage control set at?
