Wo0T! Did the volt mod for the GPU to 1.4, and I am clocked at 693/1872!!
The only thing that sux is that apparently the guy who said the VF700 might not be adequate seems to be right, as before any mods clocked at 587/1740, the card didnt get above 55C on silent mode in RTHDRIBL. At the new OC'ed rates, RTHDRIBL gets the card up to about 76C in silent mode, 70C in normal. Not sure if I like the temps being this high, so I might have to get me a VF900 or just lower the voltage/clock rates. :\
I've got a 7900gt (1.5vmod) 690/1000 VF700 CU with AS5, Max 62C with RTHDRIBL. Maybe you could use some arctic silver?
I made a mistake, I had accidentally combined the traces from the 1.3 pin and the 1.4 pin, so I was actually getting 1.5V instead of the 1.4 that I reported. Still, though, the card was getting substantially hotter at this voltage. I do use the VF700 in silent mode with AS5 and OCZ copper ramsinks.
I don't think I'm doing the RAM mod right, however, as I can not achieve memory clocks near as high as many people claim to be overclocked at. I can't get above 1820 or so stable.
So you're just supposed to draw a line (I'm assuming on the PCB) around the VMEM resistor with a sharp pencil, correct? Or are you supposed to SHADE the flat sides of the resitor on the left and right and "bottom" to form a U? I've attempted this a couple times, and either I can still only get up to 1820 or my card starts artifacting like crazy (in Windows even). I guess I'm just not doing it right..
A definitive picture would be very much appreciated..
