Using C2D Cores

post #1 of 9
Thread Starter 
I've been hearing people say using one core for this..and other for for that..What does that really mean? Also, people say I disabled one core..blah blah.

Someone explain this to me. What is mean to "disable" a core? How do you specify one core for a specific activity?

Not sure how to disable a core...


However, you can assign an application to a core:

Fire up the application, then hit <CTRL> + <ALT> + <DEL> to bring up task manager. Look up the process and right click on it. Then select affinity and check on which core you want to use. Obviously, one program can only run on one core, thus for Prime95 for example, you'll need to install it twice.

That indeed is correct. However you cant disable a core..You simply set a programs affinity not to use either Core1 or 2..You dont actually disable it.

Doesn't the 680i have the option to disable cores in it's BIOS?

I think I remember reading that here o_O

I can indeed confirm that the 680i bios does allow you to disable any core you please.

Great explanation as expected Chozart . This leads me to another question. is it beneficial in anyway to run a program/game/anything on one core rather than using both cores?

Probably not. Even if it is single threaded, the other core won't be used and also won't slow the core thats processing that program/game. Just make sure you have the correct dual-core patches from M$ and Intel and everything will run fine by itself
