Post your 7900GT Overclocks here!!!

Well, this is for a 7900gs, but since it's more or less the same chip (short 4 pipelines and 1 shader), I figure it'd be good to be in as well.

card: evga 7900gs ko
stock speeds: 500/690 (reference is 450/660)
overclock on stock volts: 580/800
cooling: stock evga ko hsf for now
overclock on 1.4v (1.394v measured. stock is 1.2v measured at 1.196v): 650/800 (no mem voltmod yet due to stock cooling)

3dmark2003 results:
24432 680/880
21140 650/800
20014 580/800
17931 500/690
16781 450/660

3dmark2006 result at 650/800: 5537
For reference, here was someone's data with 3dmark2006 with a 7900gt:
Stock (450/660) : 4695
OC (532/784 ): 5411
Volt Mod OC (685/885): 6559

So the 7900gs is holding it's own quite well and surpasing the 7900gt guy's 06 scores on his oc without voltmod

Card is getting real toasty with the stock cooler though :( seeing peak of 77'c after long loop of 3dmark


Update: Now with zalman vf900 (and thus 1.5v gpu 2.2v ram)
Setting 680/880.
3dmark03


24432 680/880

Note reference is 16781, so that's 45.6% better!!!

WOW sweet numbers for not having voltmod. i'm guessing you have the evga gt's that auto increase to 1.45v in 3d?
 
he DOEs have a volt mod. it was a NO answer to the question:
Stock volts (yes/no)?_____________

Which version of the ko gt do you have? The newer ones have an automatic voltage increase to 1.45v in 3d, which would explain your high high overclock on stock

Just did a 1.5 volt mod and I am now running at 700/900.....
