8800 Core Speed

[Jay123]

Highest i can set my core to on my 8800gts 640mb?

I set it too 587 and got werid white piexels?

Whats the max?

Thanks

Jay!

overclocking results vary so you may as well ask how long a piece of string is. Mine seems happy at 620 whereas yours as you confirm isn't. So maybe try 550 and leave it at that. Not gonna make a big difference anyways.

550mhz is the stock speed....

Is it a pre OC'd one as the standard ones are 500

Overclocking depends on a lot of factors, mine runs happily at 650/2000 but if you get corruption at 587Mhz maybe your card is a bad clocker.

Mine does 690/2000,good cooling helps though

The max will be whatever you can get it to, as all cards are dfferent.

mine does 662/2000 +few mhz on vram

660/2000 here on mines

Mine does 620/1.96

The problem with the 8800 cards is that the clockspeed isn't in 1Mhz steps but 27Mhz steps, these are the clockspeed steps of a 8800GTS: 513Mhz, 540Mhz, 567Mhz, 594Mhz, 621Mhz, 648Mhz, 675Mhz etc...

I can run at 650Mhz but not 675Mhz but there is no point in trying to run at 660Mhz as it will either fall back to 648Mhz or bump the speed to 675Mhz.

I heard something about the 8800 clock speeds not been what there shown, so my 620/1.96 clocks may actually be lower.

It could be that it drops down to 594Mhz until you select 621Mhz but it can also select the nearest clockspeed in which case your card runs at 621Mhz.

I take my clocks from ATi Tool, these are accurate clocks from ATi Tool are they? Or do I need to use some other program?

And the way it jumps to the clock increments is a bit odd, saw this somewhere [H] I think.
