Which 3D Benchmark test do you guys use.

Also, which overclocking tool would be good to OC 4890.

I am using the Catalyst Control Centre which was provided by the card.

Guys, Asus 4890 provided this SmartDoctor voltage tweak program.

After tweaking the voltage, do you guys usually leave that voltage tweak as long as your computer is on, or just for gaming?

Any other disadvantages at leaving 1.4v forever, other than wasting electricity $$$

Managed to achieve 970/1130 on an Asus HD 4890 without any voltage tweak yet.

Gonna try adding voltage tonight.

how's your temperature like. but 970mhz is actually not too bad already, 1ghz is more rare.

I think the temperature is still below 70C.

Then again, as long as not above 90C can de.

Cause my old 8800gts temperature is 70C at idle.

Is both the graphic cards functional individually? Or the cards cant sync byitself?

Curious also hehe.

Hmmm, managed to bump my GPU clock to 1gz with a voltage of 1.375v. However, for some weird reason my memory clock refuses to go pass 1130mhz no matter what voltage. cry.gif cry.gif
