So the hardware monitoring graph shows the Core Clock bouncing between 500 and 750mHz at idle?

Is this some kind of power saving feature in Catalyst?

Towards the end of the graph, I ran Crysis for a few minutes and noticed that the Core Clock stayed constant at 750 during gameplay.

Is this normal, or accurate?

Thanks,

The jumping you see is ATI's PowerPlay at work, utilized for power savings. It's perfectly normal and safe, for your HD4870...

It's a pain in the ass because it makes the screen flicker right? Download ATI Tray Tools and use that to over/underclock your GPU.
