Hi!

I have some problems regarding powerplay function in Catalyst drivers. It just doesn't seem to work. According to AMD Overdrive readings (that's the only program that seems to be able to read clock speeds of the mobility hd3450 for some reason) it doesn't matter whether it's set to maximum performance/battery life, the clocks are stuck @ 500/700Mhz. Power usage readings also indicate that powerplay has no affection on power consumption (about ~18W in both cases). Using most recent 8.12 drivers. It would be nice to have this thing working, so any help would be appreciated.

Cheers!

I've found that the clock speeds don't change in the CCC. What I use is GPUz which does properly identify when PP is on or not (just guessing based on clock speeds).

Hm, that's weird. GPU-Z shows 148/198 clocks on battery, and 249/346 on AC, but theese aren't the clocks it should have - AFAIK 500/700. Thats double weird, because it shows 550/700 clocks in the Graphics Card tab '
