Making a Quad-Core a Dual-Core.
« on: July 08, 2009, 06:21:59 PM »
Being an owner of the older Intel Quad-Core series, a Q6600, I've been wondering about making it into a Dual-Core by shutting off two of the cores.

The reason I've been thinking about this is because several places I've read that Dual-Cores are better for gaming while Quad-Cores seem to do better in the area of media encoding and such. From what I read the reason for this is something to do with the L2 memory but honestly I can't completely remember why. ATM I run a Q6600 anywhere from 3.2Ghz - 3.6Ghz and I was wondering if it would do better as a Dual-Core and the same if not higher clock. I don't do a lot of media encoding but I am a big gamer so I was curious if this would be beneficial or a waste of my time.

I'm no expert for sure. However, unfortunately, it doesn't stop me from giving some thoughts. I believe you are thinking that the games are using all 4 cores. That is not so. From what Skuzzy has said, AH is one of the few multi-threaded games around. Even then no matter how many cores you have it only uses two. So whether you have 4 cores or 2 cores it doesn't matter, it's only going to use 2. Video editing on the other hand, as I understand, can use the 4 cores. Therefore it's faster in that environment. What really matters is the clock speeds, according to experts. Most quads run slower than duo cores.  If your quad runs the same as a duo core then you are having the same experience as that duo core. Providing all other factors are equal.

That's how I see it and that's the conclusion I draw from what I have heard and read. Hopefully someone will either agree or correct my thinking.

This is true, but I'd be curious about the heat saved by literally shutting down half the CPU. That could go into bumping the clock up.

Heat isn't really an issue for me, at 3.6Ghz right now idle I'm 38C on the CPU and 27C - 30C on the cores.

Maybe so, but you'd probably still get less heat with the cores halved...then could over clock the two remaining even further. That comes from a very basic knowledge of how CPUs really work, though.

Capped till I get higher speed RAM ATM. Even when OCing I try to get a 1:1 ratio and I hit cap at 3.6Ghz with DDR2-800. Mobo supports up to DDR2-1200 though which technically gives me options up to 5.4Ghz though I doubt I could get anywhere near that on air.

You can get to 5.4 ghz on air, you may have to move your computer to 90 deg S and 0 deg W.

whats the benefits if a quad core over dual core then? :uhoh

It depends on if you're into video-related work or not. Programs such as Sony Vegas or Adobe Premier can and will utilize all four cores of a quad-core CPU which means the work is completed in a much shorter time-frame. However, since most applications and games today can only utilize 2 cores of your CPU a dual-core CPU is all you need when you won't be doing any video-related work.

I don't think it would make any sense to try to shut down two cores even if you could.  Even from a heat perspective if an aplication is only using two cores then the other two are unused and thus not producing heat.
I edit a lot of my posts.  Get used to it.

Even if you shut down the two cores, the heat increase will most likely affect the entire CPU.

you can use cpu finity ( use the windows task manager )

set all appls to finity cpu 0 or cpu 1
you have now a 4core that runs on 2 cpu's
