No way of overclocking 8800 GPU in Vista?

[GoldenTiger]

I broke down and did a BIOS flash finally... 580/1350 core/sp, 1840 RAM, runs like a dream so far on my eVGA 8800GTS after modding with nbitor. I may push it further later, but for now, I am placated :D. I too used nvflash 5.40, and checked using nvmonitor, as well as RivaTuner's monitoring probes, to confirm the overclock. I do wish the 85% fan setting I made would have stuck on bootup, but it unfortunately did not, so I still have to set that every time I startup with nTune :(.


EDIT: Popped it up to 621core/1460sp(shader)/2000ram, now instead of being a dream, it's a happy dream :D! Sweet stuff.

How do you know what to use for the shader clock?

I'm currently on XP, so I clocked mine to my usual overclocking using Rivatuner. Once in rivatuner I used the hardware monitoring feature. I showed the overclocked core and shader clock speed.

I judged based off of how it scaled under XP when I overclocked to a similar speed, then flashed with how it appeared to scale with core/shader. It was an educated guess, to a small extent. I monitored under XP previously how the shaders went up when adjusting the core speed by using RivaTuner's monitoring.

lets see what the first release driver gives us. I hate to hard flash my card if I don't have to.

I agree with you xgman. I don't want to risk voiding my warranty if something should go wrong during the flash process.

You can just use a PCI video card as a backup in case, that way you can safely re-flash the card if it doesn't work properly to the original BIOS you backed up before starting (you *should* do that) :). No risk.

ya but seriously I don't have a PCI card. I dont have anything older than PCI-e, and DDR2 ;)

yeah i had to pick one up at Walmart for $35.

good to have one on hand tho, you never know.

Done deal - I flashed to 648 / 1000 Memory and 1512 shader clock.

No more software OC for me.
