Disabling 1 core to allow higher overclock?

post #1 of 7
Thread Starter 
Okay so on my 955x4 BE

I have the ability to disable any cores I want to disable in the Bios(except for the first core) I think? lol anyways I saw the option today and was wondering if perhaps I can disable one core or even 2 cores perhaps, to just be able to maybe trim down the heat output a little bit and increase my overclocking ability higher_

Perhaps I can push for 4.6ghz with 2 cores? Might not be able to but, the theory behind it is, with less cores, it takes less voltage and with less voltage I have less heat so I can push it more

Can you push higher overclocks with disabling a core or two? Is this plainly possible?

It's true. Every core is going to be able to overclock to a different frequency. When you overclock them all and find your max, your "max" is really just the max of your worst core. Test all your cores until you find your best 2. You definitely may be able to get 4.6GHz.

I would test each core individually and see what you can get them to post at. Find your best 2 then begin testing for stability.

Test them each one by one and see what you get. 5GHZ FTW!

What's the point? I really doubt that you'll se an increase in performance

This. Unless you happen to have 1 regular core and 3 really awesome cores it would be unlikely that you would see any performance gain.

Unlocking cores I support. but not disabling them.

Disabling cores will decrease your temperatures, voltage requirements and such a lot. You'll be running higher frequency on a lower voltage.

I've tested this myself a while ago, and it works.

Yes it is possible aand it is called core balancing. What you do is essentially zero in on the core(s) that are weaker in terms of overclocking. eg:

Say you are getting a average OC speed of 3.8ghz across all cores, when u individually balance all the cores you may get this:

Core 1 - 4ghz
Core 2 - 3.6ghz
Core 3 - 4ghz

All you do now is disable Core 2 and you should be able to achieve a higher overclock on cores 1 and 3, but it's down to what you use your chip for, gaming or compiling source code. Different tasks call for different core configs.
