i tried all way up 2.2 somthing and still couldnt get above 880 and it waset stable for long im pretty sure ram is cool enugh. Whats kinda wierd is i put stock on sence it might cool ram better but gpu less and was same so i put my nv back on musta got it on better cause my gpu will now clock up to 662mhz without goin above 50c No volt mod on the gpu.

cool vmodded last night

core up to 1.5 and mem up to 2.53 (Ramsink on vmem controller)

max speeds so far are 830 core 2100 mem

Stable max so far 750 core 1900 mem

Its under water BTW

Artmasterx

you must have a nice core.

I went to 1.55V with a VF900 and can only get stable clocks of 700 for the shaders/ROP and 765 for the geometric domain @ ~62degC. FYI, going from 720 -> 760 on the geometric domain and keeping the shaders at 700 only bought about 50 points in 3dmark05.

So far as I know, ATItool/RivaTuner reads the Shader domain... for some reason, 3dMark06 will read the clock speed according to the geometric domain.

Nice clocks man!

Be careful with that voltage, though! Too much can impact it negatively. I'd try dropping it, and seeing if your max stable mem speed goes up.

Ya i need to get a silver pen so i can volt mod my gpu doing the memory volt mod didnt really help me any.

noob here but where in bios do I change voltages for graphics cards?

Bal3Wolf

You cant you have to do the volt mod its connecting points on the video card for the gpu and shading a resitors for the memory mod.

could you use a #2 pencil insted of conductive ink for the GPU vcoremod?

no You need the ink i tried to use a pencil first to it just does not conduct good enugh. You could solder a wire from one point to other point but thats kinda dangerous.

Well I vModded my 7900GS as I'm waiting on my RMA and I threw it in this Dell. I got my baby up to 725 easily on 1.5v(the memory vMod didn't do anything ) with 54°C temps according to ATiTool with the cube out.

+rep man. Great How-To.
