this club3ds max crysis stable clocks are 760/1100
removed the heatspreader, the club3d def uses samsung 1ns mem.
and the bottom of the heatsink is copper, not polished but flat.

EDIT: the mem is getting quite hot and so does the back of the gpu and gpu heatsink.
So i removed the termal tape and used thermal paste between the "memory heatsink" and the chips. cellshock style
The mem seems to run a bit cooler now but not much.

i lapped the gpu heatsink and replaced the thermal goo with thermal paste, the gpu is also a bit cooler but not much.
maybe 5 degrees...

one thing that bothers me is that the fan is always running full speed... and the funny part is the pcb and the fan DO support fanspeed control.
The cable from the pcb to the fan is missing though. and another weird thing, its the same fan as in the powercolor guru3d review but this one either doesnt have an led or the led is disabled. weird... ah well, thats enough mods for today.

oh before i forget here are the details of my card:

nf0858.00
