Overclocking the 6800 GT

[True_Orb]

Does this have to be done in BIOS, or is there a program like ATI-tool?

Also, since you can flash this to Ultra speeds, what settings do I need to set so I can get mine (hypothetical) running at Ultra speeds...and can I do it with the stock cooling (eVGA)?

That and RivaTuner are good tools for OC'ing.

the eVGA brand is reveared as a good overclocker because technically it's not stock cooling. I say this because they put on the heatsink that's meant for the ultra on all the lesser cards...so in a way it's like getting an aftermarket heatsink since it's meant for a more powerful card.

You should have no problems getting it to Ultra speeds and possibly beyond

The ultra speeds are :

core = 400mhz

memory = 1100mhz



I'm getting the 6800 GT for xmas, where can I get the RivaTuner software ?

 

[Nubius]

just google it and you'll find it. It's at places like 3dguru.com and majorgeeks.com

ok thx Nubius, you're always helping me out ... lol

EDIT: http://www.guru3d.com/rivatuner/ .... i'll save that site until the magical day arrives ....


Np man, always glad to help. Next time edit your post for me instead of putting two in a row

Thanks guys.
Do I need to change the voltage or anything else to get stable core speeds though?

 

[Hugo82]

On the "Basics of Overclocking" thread it mentions increasing voltage to CPU but not VGA so I would assume that it is not necessary.

Thanks Hugo!

Yeah don't mess with the AGP voltage..you're just askin for trouble there

No doubt that it probably would add stability, but my theory is that the graphics card is a little more sensitive than the CPU's that are made for overclocking so I wouldn't even try upping the voltage for stability on that.
