Windows 7: pros and cons of OC

Crank up the voltage and monitor CPU heat

@Kuncing13: there are many good overclocking forums out there (try this for starters) so you might examine the issue. I'm not familiar with your mobo's capabilities: can you select front side bus (FSB) frequencies, do you raise voltages, etc. but heat is the main issue (the CPU heats up as it processes more data). Your BIOS, usually, allows you to set an upper heat threshold which, if reached, will shut the system down. Your mobo SW may also support realtime heat monitors that you can keep "always on top" and observe and keep an eye on temps as they rise.

You may be able to find others (Google) who have successfully OCed your mobo and see what they did. If heat is an issue, you can remove tower panels and set up a small portable fan to blow directly in the case, or set lappy on a cooling fan base (which in my experience does not work very well). My Antec has four 120mm fans and one 200mm fan that keeps me cool enough to avoid liquid cooling which is another excellent option (many gaming cases like the Antec, are ported for cooling pipes).

So, if it don't get to hot, you'll likely stay out of trouble. But do take a bit of time and study the issue. I am sure, like me, there are plenty of OCers here who will be happy to guide you along the way. But study first. Fact is OCing is more of a mystique than a challenge.

One of the most important considerations, after even the mildest overclock is stability. Your computer might boot up fine and seem to be running stable, however under stress it could create errors and blue screens. There are several programs designed to stress test overclocked PCs. Prime and LinX are two excellent examples. Prime for example needs to be run for 7 to 10 hours and Linx needs to be run for about 100 calculations at high level memory usage. Overclocking without stability testing is asking for trouble.

Quoted for truth.

Acceptable temps/voltages while still maintaining a stable system is the most important factor on a 24/7 oc.

It is like taking Steroids...

It looks real nice on the outside
but it will start to tear you down on the inside.

you can get the girl to come to bed
but bring those pants down
and she'll laugh *lol*

In the end... for over clocking..
Just like your body.. If you push it too hard.. you will start to tear it down.. you will just take years off...or completely shut down.
A rather extreme example in my opinion.

The standard life of computer hardware can be quite long. A CPU and motherboard can work for years (my dad's computer was getting around 10 I think, and still going strong). Now, if you upgrade every, say 5 years, then you are not getting the full worth of the CPU or component.
Overclocking is a good way to get better performance for cheaper (like buying the 2GHz CPU and OCing it to 4GHz like the EXTREME edition). This may reduce the life of the component, but it will still be long enough that you will probably upgrade it before you blow it out.

This is assuming stable, modest OCing. If you OC your P4 to around 8Ghz, I promise you will melt something unless you know how to do some serious liquid nitrogen cooling.

In general OCing (if done CORRECTLY) will give you increased performance with (much) higher temps. Overclocking WILL require a good cooling system, whether it be a high quality (copper) heatsink and lots of fans, or water cooling (or even phase change cooling). For modest OCing, most air cooling is sufficient. For some real overclocking, I would go for water cooling. For SERIOUS overclocking, well... Generally you would go with either Phase Change cooling or Liquid Nitrogen.

If you want a good guide to Graphics card OCing, try this: Graphics Card - Overclock
Just keep in mind, graphics cards are much easier to OC (that way anyways) than CPUs.

EDIT: If you are going to OC, then buy (or make) a CMOS Reset button for the front or back of your computer. This will allow you to reset your BIOS at the push of a button.

The required voltages for running a P4 @ 8ghz alone will smother the chip even when using liquid nitrogen. As for finding a 775 mobo (unless solely using multiplier to oc) that will be able to handle that fsb, wished there where any.

But yea, for most moderate over-clocks, a medium till high end air cpu heatsink/cooler will suffice. It all depends on used cpu/voltages/cooling method as to what is capable.

Overall, current cpu life expectancy is around 10 years. While mildly overvolting/overclocking, you will probably not reduce the cpu's life.

When going for a HIGH overclock, you'll probably have to ask yourself this question; Will I upgrade within a few years? (or maybe even sooner depending on the severity of the overclock)

Basically in an oc, you'll be restrained by these things: used components(mobo/ram/cpu/psu) and temperatures (voltage used=temperature/cooling method/power hungriness of cpu and this is influenced by room temperatures if you're on air cooling or water cooling)

The more voltage you give your components, the more the component's life will be reduced, this goes hand in hand with how high the temperatures are when on air/water.

As that CMOS reset button, it's quite useful... haha

I think it's halarious when someone who has never even achieved a stable overclock tells everyone that it's not safe or like taking steroids. I won't even attempt to elaborate on such completely uninformed opinions.

It is safe if done correctly, whereas taking steroids is not safe, even if done correctly.
