That's weird. Mine are 1200/1400... maybe I got an Atomic with a Toxic cooler/clocks... I did buy it on eBay, so...

What version of CCC are you using? I'm on 9.6.

I wonder if Xfire, trifire or quadfire affect the ceilings?

I bought an XFX HD 4890 Black edition, meaning standard overclocked.
The GPU core should be standard on 1000 Mhz.

But when Idle it's only 240 Mhz.

When I benchmark this card I notice that it's worse then my 7900 GTO
What do I do wrong?

it downclocks when you aren't using it to save power


i don't know why your 7900 GTO out performs it though

Just tested it in game --> ArmaII
And it runs smooth. So it's way better the my old 7900 GTO

65c really isn't hot either

I already reapplied the thermal paste and it dropped it like 1c. Also the heat isn't too much of an issue but that I can't OC at all. I tried to OC it to only 875/990 and my games would crash after like 15 minutes. I just set it back to stock so I wouldn't have to hassle with it.

that "idle" clock speed is your 2D clock speed, it automatically goes up when running 3D applications.

for actual performance to be worse than a 7900, you havnt got the drivers installed correctly or something.

Got my XFX 4890 XXX today and I love it. Here is a lil screeny for you all to enjoy.


Voltage is the stock 1.3625v on the GPU.
