Turning off one core...

[Unromantic__Me]

Simple question I hope...Ive heard it mentioned a couple of times...but how do I go about turning off one of the cores of my dual core AMD? just to see if it changes anything in games and the such...

Thanks

Task manager go to processes and right click on process and set affinity.

I have to ask - WHY ?

Why turn off a core that will handle all your windows background services & tasks ensuring your gaming is that bit more stable and less prone to frame rate drops ?!?!?!??!

he doesnt want to turn it off completely just tell 1 application to use a specific core because sometimes games mess up when running with 2 different cores, sometimes 1 core gets out of sync, etc, etc. therefore both cores will be working but for 1 specific game it will only use the 1 core making it more stable, but both cores will still be in use for everything else

That times 2...Just for stability when playing games over anything else, and without having done it before, will be nice to be able to try out the difference for myself, hoping for good things

Microsoft should really add a "Force single processor mode" checkbox to the right-click->Properties->Compatibility tab on every .EXE file. Maybe they'll remember to do it in time for Vista RTM?

nah i wouldnt wanna do this because sometimes source for example runs completely fine on 2 cores, then sometimes but very rarely ill start it up and it stutters only 1 times out of 30 ill say does it not like being played with 2 cores, when it does stutter all i do is turn 1 core off and problem fixed, but i get more fps with 2 cores

There is a program out there that allows you to set persistant affinity to a program, I can remember where I was running a game server once that it would crash horribely if you let it use both CPU's, only problem is I can't remember what it was called

i could swear i read somewhere that your able to turn off 1 core and let the other core use all the cache pool for increased performance - on the intel side of things at least, might have been something to do with cores and hyperthreading. Not sure to be honest.
