im just wondering is there a way to shutdown a core of the dual core processor... i mean AMD Athlon™ X2 got 2 cores 2 separate l2 cache s so it might be possible? (or is this the most stupid question ever :))
 

for the regular usage eg browsing downloading movies i think just one core is more than enough. so just wondering if its possible :) i mean just like a manual car... this is a good to have feature id say.. if we are really concern abut energy concern. what do you think...
 


Well using cool & quiet with optimized voltage will probably do more. I use K10stat to set my 7750 at p-state1 1400mhz with .9v to CPU and 1.05 to NB, that get it down around 30W. You can change each P-state in K10stat, which is nice, also you can click on the current clock speed for each core to lock it in one P-state, so no annoying back and forth between states when the lower state will be good enough, just at a little higher load %.

thanks im new to AMD this is gud news
 


You probably already do, but if you try K10stat make sure you have the AMD cool & quiet windows driver installed and enabled in bios, otherwise it won't work. Another similar app that does work without Cn'Q enabled is PhenomMsrTweaker, but I tend to like K10stat more, for one thing because it allows increments of 50mhz on P-state 1 with DID set to 1.
