Overclocking of my Intel Pentium 4 CPU 3.00GHz 2992 Mhz Processor. How can it be done? Answered

A friend of mine introduced me to the idea of over clocking my processor. He said it can be dangerous due to over heating issues. I am willing to add new fans into my PC so long as the speed can be controlled. I will not be able to obtain a better heatsink however (My heatsink is pretty beefy already).
Ive done some research but have only been able to find very broad forums. I need to know how to do it, what to do and what not to do, how far past factory specs i can push it beyond and if my mother board with withstand it.. Also i have a follow up question I notice that the system summery stes that i have 1.57GB Avilible physical memory but i have 2.50 GB Installed physical memory. is there any way to overclock the RAM as well?

There are other risks besides overheating... I am strongly against overclocking. Read some of the other risks here: http://www.pcguide.com/opt/oc/risksRisksCPU-c.html

One of my favorite overclocking articles. You should also do a google search on the risks of overclocking before you attempt it.

Good luck with whatever you decide.

Yes my friend was telling me of some of these. He said raising the voltage too high would overpower and fry the chip as with any electronics componite. He said the highest I should try for is 3.30 - 3.50 Ghz. He said that I may need additional fans which I'm prepared for. I'll be weighing the scales of weather or not I do it based upon how easy it can be done, the risks, the benefits, and what can withstand what

I would agree that 3.30-3.50 is the most you could get out of a pentium 4, which will not be enough for you to notice that much of a difference. I just never saw the need for overclocking. If you need a more powerful CPU, then you should just buy it to begin with, or buy a new computer.

A little side note:
One danger that no one ever seems to mention is that if you have ANY issue with your computer (including software), and you end up having to call a tech support, if they find out you are overclocking, they will blame it on that and you will not get you issue resolved. (Even if it has nothing to do with the overclocking.)

I didn't know that tech support would blame overclocking. It isn't suprising, the first thing on their list is to make it somebody elses problem.

At least that will happen most of the time. It depends on the company. (And if you are hiring a tech directly, then they will be less biased. (although they may try and make it sound very complicated in order to make more money)

Always try and make sure any tech you hire has at least a CompTia A+ cert. They teach proper procedures for dealing with customers, so you will be more likely to get someone who will be worth your money... Rather than some charlatan who will make a problem worse just to make more money.

That doesnt surprise me either. On more than one occasion ive noticed options such as "have you proformed upgrades or modifications" in some troubleshooting websites. it figures they would try to blame you for something even if it isnt your fault

It sounds to me that this whole idea isnt really worth it. my biggest problem is that i simply dont have a whole lot of funds and so buying a new Intel 4Ghz processor or a new computer period is far out of the question and seeing as how i dont yet use this PC for anything more than recreation and audio it seems pointless to buy a new computer. I do however notivce one thing that may be worth my time.

Ive noticed that many computers have more installed memory these days so i may look into that. Ive upgraded from 512 MB of physical memory and noticed an increadible boost in proformance. it seems that RAM has more effect than processor use
as for the availible memory, What could I do to expand this?
I have a highly vague idea of what virtual memory is. Actually i have no idea about this concept except that i used to receive popup messages alerting me that i was running low on virtual memory when I had 512MB of RAM. not sure if i could adjust this for better proformance or not though

Here's the difference between virtual memory and physical memory (ram):
Virtual memory is space set aside on the hard drive to be used as RAM.
RAM is memory which basically controls everything. Virtual memory doesn't really change much in terms of speed, and here's why:
A hard drive is platters spinning around very fast. Your data is stored on sectors on the drive. If you have data on a sector that you need to access, you have to wait until that sector is under the read/write head. If you need to access it again, you have to wait until the platter has made a full rotation. RAM on the other hand has no moving parts, so you can access data stored on it without having to wait for a mechanical process, and the data can be read randomly. (Thus the name Random Access Memory) Because the hard drive uses magnetic platters, when power is shut down, it does not loose the data. However,data on RAM is stored with electricity, so when you shut off the power, all the data in RAM is lost.

When you run a program or file that is stored on your HD, it is not actually run on your HD, rather a copy of the file is called from the HD, and copied into your RAM. (That's why you have to save files... That takes the copy that is in your ram [the one you are working with], and it copies it back to your HD.)

Long story short, virtual memory which is stored on the HD doesn't really help you because you are still waiting for the rotations. (The reason it is used is because it generally isn't fragmented, which saves access time as opposed to just accessing fragmented files)

I would suggest getting more RAM for your computer. It will give you the best cost/reward in the end. Just keep in mind that your computer is 32-bit (x86), so you can't address any more than 4gb of RAM. (Actually I believe the exact size is 3.95 GB... Or something like that.) You can put more than 4 GB in, but it will only be able to see/use the 4 GB. Also only certain types of ram can be used. Google ram buying guide, or how to upgrade ram for more info.

I had the exact same setup and fiddled around with different OC software, ultimately I abandoned the whole idea as the incremental increase in performance was not even noticeable( despite the OC sofware showing me imperical evidence that the cpu was working very hard).Without the funds to replace a borked cpu I decided the risk vs. reward just wasn't there.However if I had a more capable cpu with tons of room at the top for playing around, I probably would go ahead and give it another go.


It sounds like im having that same idea. i wouldnt be able to replace the CPU if i killed it and certainly couldnt replace the computer. I guess this is just one of those lost projects

I always thought  Overclocking the cpu will do the same to the memory
it talks to. 
Old style dynamic ram was the only memory that I know needing a clock.
The clock used to be set through the boot up sequence.
Today's processors have temperature safe guards which may protect
your processor with shut down.

I recall serious over clockers went to liquid cooling for heatsinking of the

Yes my processor has this fail safe on it. I know from experience from when I rebuilt this computer and there was a plastic guard over the heatsink and fan that suffocated the processor.

as for the memory I'm glad to see that they run hand and hand with each other
So how can this be done?
