I am with Pwnana. I have never heard cores being disabled at factory settings. Underclocked, yes, maybe. But disabled? This is a first time I have heard of this.

And you would only notice an increase in performance if you are already maxing out your two cores you use. If you aren't it won't really matter much if you have two extra cores because you aren't fully using your first two cores.

O, well if its a real quad core processor then yes, by all means set it to 4 cores, you will notice a performance increase.

I don't get that O_o. I know how factories underclock processors to extend the life and keep it from overheating, but I've never heard of them cutting out half of the cores before. Look around for some other overclocking tools and guides, and you should be able to use all four cores at maybe 2.65 ~ 2.70 instead of 2.5. I wouldn't recommend all 2.8 as that would overheat way too fast. There are some tools to help with overclocking and voltage and testing your system for stability, but I can't remember any right now >_<. These would help you reach the maximum safe overclocking setting.

Even if you ignore everything up there, I believe you would notice an increase in general performance with 4X 2.50GHz instead of 2X 2.80GHz.

Pwnana,

Some processors by AMD including mine have 4 cores but 2 cores are disabled because of factory settings. So can anyone answer to my question

I didn't know you could change the number of cores in your processor. If it is possible, then its probably just emulating 4 cores, in which case I would recommend keeping it at 2X 2.80. This would allow you to run individual programs faster, which I think is more valuable then running multiple programs slightly slower. .30 GHz is a BIG difference.

I don't know why I have it. How do I remove it?

To change the Avatar, try these steps;

1) Click on the Profile link (adjacent Logout selection at top of Forum)

2) Click on "Select an Avatar" button of your profile table

3) You should now see a box which informs "Current Avatar in Use" and another that allows you to "Upload an Avatar" - If a picture is shown here, then click on "Remove".

4) In the first box you should now see the "Current Avatar in Use" - if that still shows "ADMIN ", choose item 2. in the box to select "Forum Default Avatar".

IF all the above fail to reset the avatar suitably, only recourse is to refer back to Ashraf for resolution.

Sorry, best I can offer to help here, and cannot advise on the processor clocking isse.

Ok thanks

Unfortunately, nope. I've never tried to overclock/underclock or do anything to mess with my processors. My guess is that more cores will allow you to do more true multi-tasking (i.e., up to 4 things) rather than switching active processes in and out of memory quickly. But this is truly a guess. And whether this would be noticeable to you in your everyday computing probably depends on what you do on the computer.

Can anyone respond to my question about Quad Cores?

I have a Amd Athlon 64 X2 @ 2.80 GHz and at 1.300 volts. I can unlock my processor to 4 cores if I under-clock it to 2.50 GHz and set maximum fan speed. My question is will it really give me much of a boost and do I need to adjust voltage?
