Overclocking dual core

Hi, I am having some trouble, I want to OC my cpu a little bit, when I up the voltage it does not do the cores evenly, it only changes one core, is there any way to fix this?

Board:
MSI P4M900M/P4M900M2 (MS-7255 v2)
CPU:
DualCore Intel Pentium E2140, 1600 MHz (8 x 200)
 
alright, when i go to my bios, under frequency control, it says adjust cpu fsb speed, it goes from 200 to i think 533, when i move that it does changes only one core, i cant find any other option that says fsb on it
 
You can't overclock just one core. What program are you using that is telling you only one core has an increased voltage, or that only one core has a faster clock speed then another?
 
When I change the fsb speed, and boot up, under windows system properties it will say like 1.8Ghz and 1.6Ghz

That is not telling you the speed for both cores, the first speed is the default factory speed, and the second speed is the actual current speed.
 
ohhhh, alright that helps, so say I move the frequency to 225, which will put it at 1.8 ghz, then its overclocking both to 1.8 for a total of 3.6? I also have everest ultimate

Yes it overclocks both cores, but no it doesn't equal 3.6GHz.

Think of it this way, a single core processor at 1.8GHz means that only one lane of traffic can move at a given speed. A dual core processor has two lanes moving at the same speed (apposed to just one with the single core), which means you can process more information at the same time. it does not equal a single faster lane of traffic (which is the same assuming that the cores are added together).

Correct, but its not a 'total' realy bugs me when people say, i have a 5GHz cpu when realy its a dual core 2.5
 
Well, that's just a lack of knowledge on their part. Either that or they have some CRAZY mad overclocking skills and an amazing water cooling system, but I highly doubt that.

They can brag about having 5GHz, but we really know...:D
 
ok so i have what might be a dumb question, but the computer that im going to put together now will be my first dual core computer, so which would be faster overall a single 6ghz, or a duo 3.0?

They never made a 6GHz processor, or anything close to it. The fastest single-core desktop CPU ever made was 3.8GHz.

i know that, i was thinking more hypothetical here

Well it's difficult to compare a 6GHz single core to a 3GHz dual core, for the most part the 6GHz single core would perform better, especially in games. Although theres nothing even close to that, so theres really no reason to even be asking.
