I wouldn't be suprised if you don't see 700mhz on the core.

whats speed your memory at?

Memory is at 1600 (800), can't get it any higher, using the 84.20's which seem a nice set.

I'm using the beta's 84.20 with no problems got a big boost in 3d mark 05 over the 83.90's

what clocks are you running?

the fan is going in a week anyway ,getting the VF900 I never use stock fans on any gfx card I have anyway.

Stock clocks, had some blue screens with 84.20 during pro evo 5, might have been all the driver installs, but I was using DC, when I get time, I will further test
 
I'm using the 84.20 betas following the link form nvidia site.

so everyone is the extreme G 82.20 v2 the one ? might have to give them a whirl. :)
 
xfx 520/1500

No articfacts test 1 and 2 slight artifacting end of airship, stock cooler, no volt mods, side off, fan blowing on it, thats it, it would go further and I dare say with a volt mod(which I have no need for) it would go much further

same as mine :)

whats the max clock artifact free?
 
I was having some powerstrip issues as already stated, and installed coolbits in order to check the clock and check the 2d/3d clocks, do you know if this has changed from the 7800gt 2d for windows quiet fan etc etc or is this a driver quirk?

what are you running 24/7?
 
Just installed my XFX 7900 GT Extreme Edition (520/1500). Works as advertised and benches similiar to earlier posts. :)

However when I detect optimal overclock through the driver it really doesn't offer me any extra. I've tried it a few times and the best I have got is 523/1536. :(

Does this mean that XFX have really tested and badged their cards according to optimal overclock?

I guess I could force a manual settings - but I only got it today...

Stock 520/1500, underclocking results in no temp drops, another driver quirk, who knows. Although I have not tried it with these drivers XTreme-G 84.20.v2 which are performing superbly,from here http://forums.overclockers.co.uk/showthread.php?t=17549239 thanks to Scoobie Dave. Just had a run of pro evo 5 definite IQ improvement, nfs-mw still glitchy(so whats new) but running smoother, and toca 2. The more I play with this card, the more I am impressed with it, especially with that tiny cooler, I have been gaming at 570/860 nfs-mw 4/16 multisampling toca 2 4/16 pro evo 5 runs full at stock
