HD2900 pro problem

[hillbilly2]

Hi all,

I have bought a 2900 pro (GDDR4) and have installed it but my core is at 506 mhz and the memory is at 513 mhz.........why so slow Rivatuner will not let my overclock and if i could the max the memery will go in the slide bar is 775 mhz

Any ideas???

In Riva Tuner (2.05) select 3d clocks first then move them You might have to enable the overclocking feature in that first however.

Sorry for being thick guys,but how do i see the 3d clocks? I carnt find them in ATI CCC eather?

Any help?????

You need to do as Scougar says, as you cant see the 3D clocks in the CCC, as you can only view CCC on the desktop, and when you view it on the desktop, your on 2D speeds, you need to run a game or something, for the clocks to change to 3D speeds, but doing that you cant see the CCC, or i think you can run the artifact test in ATi Tool (spinning cube) to see the clocks change to their 3D speeds in that to.

I tryed that,but the clocks still say 506 and 513 have i got a dud card??

If you open CCC Overdrive, the Requested clock speed is the clockspeed it will run at in 3d.

Try 3dmark06 and psot your score with CPU
