what kind of Ocing are you guys seeing on your 6800Ultras? and what do you normally run on w/ no artifacting
 
Your OC is pretty darn good. My BFG Ultra won't go much above teh stock BFG speed (in sig).
 
The keeper of the 3DMark05 list speeks!

The average OC speeds for a 6800 Ultra are 446/1,174.
Here is the list of what I got.

The OCs for 6800 Ultra SLIs are relevant because they are no different in overclockability than normal 6800 Ultras.
If anything they should be a little lower because you can only OC as high as the weakest Ultra will allow,
plus because there are two cards there is lots of heat being created.

Nice list you compiled there. If only someone could do that for the 6800GT...

You're keeping her clean right? Dust is thee enemy!
 
grrr hehe I cant break 6000 mark because it will start to artifact if I bump it up any higher :)
any tweaks that does not involve overclocking :)
 
ya mine didnt artifact at all at 460/1200 w/ 71.20 but i like the stability of 71.84. To check for artifacts i just run the 3dmark2k5 pro , the pixel shader test. its a quick way of checkin if it artifacts hah. i got it to pass the test at like ~475/ ~1250 on the test frequencies one but haven't tried the 3dmark let me see if i can oc my chip a bit more. :)

Just look at the 3dmark05 list... The average GT core and stuff are listed there.

I wouldnt use that list or that utility to base an OC. People overclock well beyond the point of stability just to get a score. Unless you wanna destroy your card and play with artifacts covering most of the screen, dont try to mimic those OC's for game play.
 
highest clocks I got it to were 466/1290 but it wouldn't go any higher than that
