Is it possible to overclock the CPU of a pre-made computer?
Cos I know you can if you build it yourself (don't know how to but
still)
If it is possible, how do i do it and by how much? (I have an Intel
Celeron D CPU at 3.46GHz)
Thanks
peace, love and empathy

You could expect a performance increase of a few percent at most. Even if
the motherboard/BIOS in the pre-built system DOES allow for overclocking
(changing FSB speed and CPU core voltage.) Your performance increase would
be minimal because the Celeron D 3.46 GHz CPU is already almost at the
highest speed for that series of CPUs (if not THE highest) so the CPU speed
increase would likely be limited to a few hundred MHz. The other
limitations pointed out in the previous replies to your original post would
further limit the maximum performance increase to 'barely detectable'.

Very substantial performance increases can be obtained with some CPU series,
especially if the CPU is not already standard clocked to near the high end
of the range. For example, the Core 2 Duo CPU series is HIGHLY
overclockable, some of these CPUs (the E4300 and others) is easily
overclockable by 50% to 75%.

Hi djak,

Most pre-built machines use a cheap motherboard, just expensive enough to do
what it's supposed to do, (which doesn't include overclocking) until the
warranty runs out..

With an own-built system you can pay an extra ~$40 and get a motherboard
with more options. Overclocking options are usually 'extras' and not
available on the cheaper boards. You can see, therefore, that the chances of
overclocking a pre-built machine are slim.

Frankly, your CPU sucks for overclocking. As Phil said, even on an
OC-friendly board you wouldn't be able to get much more out of it. A better
option for you to increase the PC's power might be to find out what
motherboard you have, check it's CPU support list and maybe get a P4 CPU for
it instead of the Celeron.

Second-hand P4s are often as cheap as chips as people are upgrading to Core
2 Duos/Quads. A 3GHz+ P4 at stock speed is a big step up from your Celly.
Also, if you discover that your motherboard *does* provide OCing options a
cheaper/slower P4 could be OCed.

To sum up; Pre-builts rarely support OCing and even if yours does you have
possibly the worst CPU for OCing there anyway.

The next step if you're serious about increasing power is finding the mobo
make/model and letting us know and/or doing your own research into it's
capabilities.
