HD4850 acts like a "Cool n Quiet"

post #1 of 6
Thread Starter 
My HD4850 seems to lower its clock speeds during idle.

Is this typical? or Am I just on crack?

Stock clock:
Core 625
Mem 933 (I think)

idle clock
Core 500
Mem 700 (I think)
Build 1.2.1

I think those are 2D clock and yes HD3 and HD4 do this to lower power consumption.

All ATi cards since the X1K series, and maybe even some X8XX's have done this. I personally love it - keeps power consumption, fan speed & heat output down at idle.

ATI PowerPlay™ Technology delivers high performance when needed and conserves power when the demand on the graphics processor is low.


That's what it's called.
