P-6831FX Vista x64 8800 GTS overclock, bluescreen?

Anyone had any luck overclocking there 8800mGTS on vista x64? I can overclock fine on Vista 32bit. But when I tired to overclock on Vista x64 Sp1 I get a blue screen error and crash that reads nvoclk64.sys or something.

I think its the display drivers but I can't even go up to 550 core....Anyone had any luck overlocking on Vista x64? I was using Forceware 175.80 x64

Seems the visa x64 forceware drives are stable at the slightest overclock. Same becasue i prefer x64 Vsita to 32bit and I want to use all my 4gb ram.

 

sure you can, but i cant find my 3dmark scores for it, because i deleted them... i was in the mid 10 range.

 

I can't seem too odd. What driver did you use? 175 ?

 

I also cannot overlock in vista 64. I downloaded ntune but when I try to move any sliders and click apply, it just goes back to normal settings.

Anyone know why or a workaround?

 

yes: you need the new nVidia system tools with ESA support.

it works on vista 64.

 

Sweet thanks!

 

anytime man...

 

I've only ever overclocked my desktop gpu, how stable and safe is overclocking the 6860's mobile gpu?

 

remember how careful you were to overclock your desktop gpu? looking for artifacts/boosting it a small amount at a time/stressing the gpu by benchmarking it, kicking it down a notch if you find anything awry with the gpu...

same stuff applies here.

 

i can get to 575, 900 stable, anything past that results in black screens, so I say start below that and go up from there, some cards have higher or lower tolerances then others.

 

i use 600/800/1500 zero issues
(9800gts clocks )

 

i get black screens when i up my shader clocks which is a bummer cause thats where all the framerate boosts are coming from not so much from the memory or the core . i always thought it was my power supply crapping out on me when the black screen hit but i bought one of the huge 180w PS and it still did the same thing . So now i have 3 power supplys and still cant clock the way id like to .

 

I am using 177.84 and am GPU overclocked via nVidia Performance Tools. In fact, through a bit of trial and error, have found my cards "sweet spot" to be 648/923/1428. Quad hit the nail right on the head when he said the biggest performance boost comes from the shader clock increase.
