Hey all,
I was wondering... is it possible to overclock a dual core cpu? I mean, since there are 2 cores, would you be able to overclock them? And would you overclock them seperately? Thanks!

Yes. Not separately. Any time you have 2 cpu's in a system the MUST run at the same speed.

Someone told me that you could disable one of the cores and just run it as a single core cpu. I"m guessing this isn't possible is it...
Maybe if somehow you could do a pinmod to cut it out, but WHY?? Why would you buy a dual core then

Well if you going for a max overclock for like a run of superpi or something. That way the 2nd core doesn't heat up or take up ampage.

I was always under the impression that X2s (and dual core CPUs in general) were much cooler when only one CPU was being used, which pretty much negates the need for disabling one core. There's a thread somewhere where a member ran Prime95 on only one core of his CPU but didn't run it on the other. When he ran two instances of Prime95, his CPU was ~5 C hotter.

On the 840EE it is possible.
I can switch from quad to single on the AW8

heck, my single core "heater" pushed my cpu (with xp120) 10C from idle to prime95 loaded - almost instantly (50C to 60C) upon starting prime, and dropped 10 just as fast when stopped. So sure, that second cpu at idle in a single threaded sythentic test is going to be idle cool, with the loaded proc loaded hot.
I'm somewhat glad I got some experience with such a hot proc (my first build), now looking forward to an X2 - and ready to cool it (knock on wood).

yeah but once you start pumping high volts through that 2nd core its going to create more heat. And you have to remember just because the core is idle doesn't mean its not creating heat. Does a single core at idle run at ambient temp, I think not.
