Well the block\block i have have the dipp inn them. My vrm's have the same hight, so i put two pads on one an two on the other. Same thickness on one side and a thinner one on the other one. Works like a charm..
No my problems are window related i think.. Not sure.. But it stops at 950/1260/1,149v when the cpu q9650 is @ 4,5ghz. Think thats the max for my asus card. More volt = restart. 960 on core clock = restart..
Hope the block works just as well on my saphire card..

This is the block and mounted on the card,
