Then I think it will be fine as your mobo might have OC headroom on the power fases I don´t see why it wouldn´t work.

The GA-78LMT-S2PT is a 3+1 phase board rated at a 95W TDP limit for a reason. The VRM design is failure-prone with quad cores above 95W TDP, and should not be used with them. You may be able to push below a 95W TDP-like heat output and power consumption with an undervolt and underclock, but this may require as much as a 25% reduction on your performance from there.

thanks a lot.the default speed of my processor is 3.3..so you are telling that i should make it about 2.5 and reduce voltage likewise right?
