I have an Intel Core 2 Duo 6400 2.13GHz processor. Should I overclock it? If so, how?

We need to know if it is custom built or not.

If you bought a computer from a company, there is a good chance you will be unable to overclock it. However, if you built it/had a friend build it, you will be able to.

It is safe, just don't go crazy on the FSB speed.

If the multiplier is unlocked, then it should be easier.

Anyway, the best way to overclock is to turn on the computer and enter the bios (Depending on your system, it is F9, F1 or Delete). Then, try to find something that either says "Power Overclocking", "Overclocking", "Advanced Tools", or "Advanced Bios Features". I can tell you which one you need to select if you know your Motherboard.

When you find the right one, enter it, and see where it says FSB. Increase the FSB slightly.

If you have an open multiplier, see where it says CPU multiplier and Increase it slightly.

Keep increasing it until the computer is unstable, then decrease it. Fine tune until you find a good Clock speed.

Good luck!

If you will compare the speed of the three processors, AMD Turion X2 Ultra ZM-82 2.4GHz will win. But of course, I read an article/comparison from pcworld or pcmag(i forgot), they showed that Intel Core 2 Duo is better that AMD Turion X2 processors. So that means even a 2ghz intel can match 2.2ghz - 2.4ghz. I will go for an Intel Core 2 Duo P7350 2.0Ghz

Well, overclocking a processor is inherently risky. You can also overclock other part of the mobo, though, such as RAM and FSB. However, I strongly recommend that you do not attempt to overclock any part of your PC since it doesn't sound like you know much about it. Here is a link you can read up on, and I think it is probably the nuts and bolts of the whole OC'ing that you'd be looking for.

My 6400 ran at 3 GHz without any problem using the stock cooler and voltage. I left it at 2.66GHz. What motherboard and cooler do you have? Are you 100% sure the cooler is perfectly installed?

If you have a very low-end motherboard, you probably won't be able to overclock. On my P4M800PRO-M, any overclocking at all was hopeless (2.33GHz wouldn't even load the OS!). On my MSI Neo3, the exact same CPU and heatsink, fan, memory, and CPU overclocked effortlessly.

Overclocking is safe. If it overheats, you computer will automatically turn itself off. The best way to do it is through the BIOS. I have my Core 2 E6750 overclocked using the stock cooler and it never gets above 50C.

Never completely safe but Core2Duo processors are extremely overclock friendly. You can bump you processor speed up to around 2.4 to 2.8 G without much risk. Just don't increase the vcore voltage and watch your operating temps, you'll be just fine.

You need a good heatsink as stock heatsinks rarely are adequate for OCs.

Here's a good 775 heatsink.

Expect a 3Ghz or so overclock with an aftermarket cooler. 65nm Conroes (E6xxx Core 2s) usually top out around 3.2-3.4Ghz

If the CPU is new, and you overclock it, then the CPU goes bad, Intel will not replace it.

Overclocking is never safe.. There's always the risk of overheating the CPU and blowing it up in the process.

I wouldnt recomend it but if you were to di it the best way to di it is to take it to a computer shop (PC World) if you live in england and ask them to do it fr you.

they also can tell you if it is recomended to do it
