ATI Tray Tools (HIS x1900xt) Reading wrong Core/ Mem speed.

[Admiral_Cecil]

Hello,

My video card is the HIS x1900XT IceQ3 version. The default clock is suppose to be 625 core and 1450 mem.

In addition, it seems my overclock is locked, when I move the slider, it keeps defaulting back to 500 core and 1188 mem.


How come ATI Tool and ATI Tray Tools both say 500 core and 1188 mem? How do I fix this?

I suspect that the lower clocks the Traytools are reporting are a result of 2D/3D throttling. A GPU will run at lower clocks when there is no 3D applications running, in order to save power and prolong chip life.

I would recommend you get RivaTuner to see what the 2D/3D clocks are and to see about overclocking. I've had great experiences with Rivatuner with multiple cards, including overclocking and unlocking pipes. Unfortunately I can't say how well it works with ATI because I've always had Nvidia. AFAIK it works fine with ATI.
