7900GS overclock question - Page 3

post #21 of 27
Thread Starter 
well the core only goes up to 5hundred something until i actually see artifacts...and no beep or reset of time........its supposed to detect it then adjust accordingly right? go clock back down until its stable then stop? mem was going almost 900...i didnt see artifacts but it seemed to high to me so i just stopped it...

I would set them manually the. Try 500/700 and scan for artifacts for about an hour (watch your temps.) I wouldn't go past 550/800 on stock cooling. The max I would try even with good cooling is 700/850.

Hey I manually set my clocks to 495 / 720 (took 90% of 550 / 800) and scanned for artifacts for 30 minutes. The temperature peaked @ 63C and didnt go anywhere from there. my temp then when down speedily to around 50C where it normally stays. i could go higher right?

k i decided to try 94% of 550/800 so i went 517/ 752. did artifact testing for 30minutes with no problems. 64C was the temp.

96% @ 528 / 768 30min testing w/ no problem 64C still.

hows this? is 64C high? or is this fine?

tried 3dmark06 again, score is 4796, 599 score improvement from stock. temp was around 58C i think after exiting 3dmark06 and seeing it on ATITool taskbar......you guys think i should OC more?

when i used ntune to "find optimal" i did 576/801 and got a score of 5015...but i never did any artifact testing in atitool. you guys think i should increase from 528 / 768 and keep going? ty

remember temp in atitool has only got up to 64 MAX from 50 NORMAL

BTW 3dmark06 registers my clocks @ 546/769.....is this a problem? what would be the case...ty
also, my drivers arent "3dmark06 approved", i got the newest 91.47 i think..

I Got mine pretty far too, I have to have the fan set at 60%, and under load playing crysis it gets around 75-77 Celsius. I think its a pretty good OC compared to the very stock 450MHz.


450MHz 605MHz

Stable Speeds:

This is great, but please don't bump old threads, make a new one.

i used to run 635/835 on my evga KO 7900GS.

My 03 score (with an 939 X2 @2.64GHz) was 21742.

I don't have any 05/06 scores in my ORB anymore with that card though.

Those cards are awesome overclockers.

*** Edit - sorry I didn't see this was an ancient thread ***
