I like ask if any of you know how the factory's overclock there cards? I see cards clocks at say 500 mhz. Then I see the same card with factory over clocked to 576 mhz. How are they doing it? Is it possible to take the stock card and overclock it myself to 576 mhz?


Thanks for any help.

they are doing that on bios level, you can do that do, get bios for your card and edit it, but that will void your warranty. You can also get a program like rivatuner and OC your card in windows. This shouldn't void the warranty unless you tell them you overclocked the card.

As said all they do is edit the bios! ... its very easy to do yourself! ... my card was a stock 8800GTS 640MB, 513MHz clock core, 1188MHz shader clock & 1.584GHz memory clock.

I have took the bios of a EVGA 8800GTS 640MB (KO.ACS³) version and edited the bios to 626MHz clock core, 1458MHz shader clock & 1.8GHz on the memory and force flashed my card with that bios, been like this for months .... runs games like a dream!

But does flashing the bios always work?

Yip, as long as you do it right theres no way it cant work, ..... the good thing is your card will run at the bios edited speeds no matter what... you dont have to mess with 3rd party overclocking tools .... i can formatt my system or put my card in another system ect no matter what i do it will run as these speeds! .. as far as my card knows 626MHz clock core, 1458MHz shader clock & 1.8GHz are its stock speeds!

Just dont do something stupid like try and flash a 8800GTS 320MB with a 8800GTS 640MB bios, .... or dont try flashing a 8800GTS with a 8800GTX bios ect! stick to a card that is the same mobel & has the same amount of memory as yours!

Also make sure you use rivatuner to overclock first & stress test the card at your desired clock speeds before flashing! ... i stress tested with atitool(2 hours) and ran 3dmark06 a few times to check for artifacts before i flashed my card!

Also make sure your card can handle the heat of the overclock! I have a Thermalright HR-03-PLUS cooler so i dont have to worry!
