im getting very confused, i got an (XFX) radeon hd 5750.
and my problem/confusion is with the gpu/memory clocks.
at full load the clocks work at 700/1150 like when playing games.
then when doing normal windows operations, internet browsing etc.
the clocks are 400/1150.
then arent the gpu/memory clocks suppose to go lower or maybe while idling?
Make sure to disable ati overdrive and leave clock setting at default.
After Catalyst 10.4, and modification to factory clock will make you ineligible for the idle clocks.
