When I first purchased the board the PWM area popped and burned. My second iteration WC setup now has RAM sinks on the PWM and have not seen the temps go over 55c.

Very interesting WC loop you got there. The GTL ref never gave me any legitimate stable oc's. When I first played around with GTL I always had to be ready to reset the CMOS because there were many C1/weirdo beeps.

The board is great and easily overclockable, have nothing but great things to say. Makes you wonder why I invested in the DFI "Green" (LanParty UT P35-T2R).
