Here's my oc [attachmentid=573578]
750 core gives me some random artifacts though and my mem is a bit of a chump.. cant oc very high on mem  sweat.gif

wow cool core speed rclxms.gif btw what software you use to check artifacts ?

QUOTE(D-Zire @ Aug 28 2008, 10:50 PM)
fan is running 54%....load temp still 105...i cant imagine the temp if i put it to auto....fries my card instanntly....anyhow i'm using a raidmax sagitta casing...i dun think is the case airflow problem....must be the card la....hmmm...generating too much heat
*
Try 65%, that would be better.. I wonder why you card is so hot, try to improve your inside casing ventilation and open the case to see if the temp would be better.

probably the thermal paste not enuf or too many, lousy contact with GPU core la. U try go RMA, say temp over 105c, i think they can RMA for u if their side also high temp.

I think he's still on stock thermal paste which is damn sucky. doh.gif

Core > Mem

But if you increase it too much, u need to increase the volts too if not there would not be a differences.

You can do the fan speed adjustments thru CCC, edit the profile with notepad and save it. Im not using any fan for my HD4850 tho tongue.gif

After the bios vmod you should be able to run it at 700/1000 at least.

What OS ? Clean install ?

Without clean install you wont notice it coz you are still using the 8.7's files smile.gif
