No, it's the "Superclocked" ... it comes stock at 1.5v as far as I know ... But is it good? I've never overclocked a video card before. So far I'm at "No errors for 18:00:00 sec." on ATiTool. I assume this is a type of stability test? Checking for artifacts sounds like stability to me. The temps aren't too bad, I played Quake 4 for like 30 minutes and checked and it was only 68c. I have a VF900 I just put on, so I think the temps will be less once the AS5 sets or whatever.
Wait, that has artifacts in the ATiTool Display, Delta of 600 in 7 Pixels, and you can see them in the top left corner of the furry box, slow it down and keep check of how hot it is running! That seems awful.
Forgive me if these are just blemishes in the display, its just that that happened on an X800GTo of mine that I had to RMA!
ATI tool always says no errors for x amount of time, the time being since the last artifact. I think it makes a windows beep noise too when there are artifacts.
Either way those look like artifacts and you should probably lower your overclock a bit. If you don't think they are (could just be jpeg compression or something) then try running 3dmark05 or 06, they are great for showing artifacts. Just run it like 4 times in a row and see if anything looks really strectched out or is artifacting.
