When you overclock a CPU,how much performance gain does it give? (In real world tasks,eg. games)

Thanks

Depends on the cooling (and various other things), but you're looking at a 10-20% increase usually. Most games aren't limited by the CPU though, so you might not see as much of an improvement there, at least on higher resolutions.

Oh, Ok. Thanks for the explanation. So is overclocking just really for benchmarks and bragging rights?

No.

Let's say you have a E8200 which runs at 2.66 GHz and you overclock it to 3.33 GHz. You've increased the power of your cpu to that of a E8600.

Is this just benchmarking and bragging power? No, it's an increase in computing power. And your cpu also has a major effect on the graphic system. If you try to power a 280GTX with a Pentium 4 cpu you'll find that your 280GTX performs well below specifications. Whereas a 280GTX paired with a overclocked E9650 will perform above the rated specifications.

oh really? never knew that! thats kwl to knw, but then again it does have the chance of destroying your processor, then try to get a 280gtx to function. lol!

Most new cpu's have a built-in heat limiter and I haven't seen/burnt one up yet. I'm not saying they can't be hurt, but with a decent heatsink it's hard to do.

The old AthlonXP cpu's didn't have a heat limiter and I destroyed at least 10 of them

I agree with slaymate on this. I work for Navy Federal Credit union, and up until acouple months ago my team (network/application management) built all of our own servers. (The buracrats took over even further, and now their is a whole new team dedicated to building our app servers, and to say the least, they are pants-on-heads retarded. BUT back to what I was saying; Even in the hot environment of a multi-processor server (each one running 2-4 Xenon duel cores, which were stock 2.66ghz, we overclock them to 3.0ghz. Now this may not seem like a huge number in gain, but the performance increase is phenomenal, and saves us money in the long run.

On a home pc note, the sky is the limit, the only processor (of late) that I have managed to fry was a Phenom 9850BE (it was a 2.5ghz stock, I had it running at 3.3- on a water block that was slightly too small. (also i pumped too much voltage through it, and instead of leaving it alone for a min when it would auto power off, I proceeded to keep boot cycling it ROFL.

Overclocking a computer's processor or memory causes it to go faster than its factory rated speed. A processor rated at 2.4GHz might be overclocked to 2.5GHz or 2.6GHz, while memory rated at 200MHz might be pushed to 220MHz or higher. The extra speed results in more work being done by the processor and/or memory in a given time period, increasing the overall computing performance of the PC
