How Do U Overclock A Cpu?

[silent h3ro]

I wanted to know how to overclock my p4 2.26GHz cpu to like 2.4GHz without any additional cooling in my computer. :helpsmile:

Check the HardWare guides thread thats pinned, second post.

I saw it but it doesnt describe how to overclock pentium4s. It says to ask the members with teh p4s.

First of all you need a mobo capable of supporting overclocking.

So if you can provide that info we've got somewhere to start. And it would bu useful to know what cooling you've got at the moment, but current temps will probably suffice if you don't know what's inside your pc.

Other than that the principles are the same. The multipliers are locked on P4 chips, but that is now the same on most Athlon XP+ chips, so the only choice is to change the base frequency.

But 2.26GHz to 2.4GHz is not a very big jump, it is doubtful if you would notice the difference except in artificial benchmarks. You need to be looking at an increase in performance of about 20% for it to be really worthwhile (2.7GHz in your case), but as you obviously know that could raise temps more than is healthy. The only way to find out is to try it.

ok I&#39;m gonna sneakily jump in here as I too am looking at oc&#39;n for the first time. :ph34r:

I am in the process of reading through peerzyboy&#39;s guide.

My system is

P4 2.6 cpu stock intel cooling
thermaltake xaser III case with all the seven fans running full tilt, and the side off at the mo :rolleyes:
abit ic7 max 3 mobo
1 Gb corsair pc 4000 ram
radeon 9600 pro gfx 400/300 @ 530/305 (this is the only current oc, did it yesterday)

temps at the mo

case 30 degrees celcius, cpu 39, pwn (whatever that is) 33, gfx 36

any guidance would be much appreciated

oh the cpu is a northwood ht cpu :)

My compuetr here (http://www.vprmatrix.com/products_desktop_226R.asp). All it says for my mobo is Intel full ATX motherboard. The only two fans I see in my computer are the heatsink for my cpu, abd the fan on my graphics card. I just wanted a couple hundred megahertz because I dident want my computer to heat up too much, as I have no real cooling.

OCin with pre-built comps is usually harder since you prolly have a mobo that doesnt really support it.......

open your comp up and see if you can find any model numbers on it, and check the manuals for info, were especially looking for:

mobo brand, model and chipset
CPU model (got that)

and if possible RAM type

I opened up my computer and the mobo says: Intel Desktop Board D845EBT. Chipset? How do I find that out?

Why not do this the easy way?
Reboot your machine and enter BIOS...see what options you have available.

I saw something about Chipset Memory Timing Control but that was it. Is that what I wan&#39;t?

[Storm]

thats for overclocking the RAM ;)

see if there is anything about FSB, front side bus, or bus speeds....... and what can you set them to?

No&#33; :( I can overclock memory but not my cpu&#33;? :angry:

[silent h3ro]

Is there a way to update BIOS so I can overclock my CPU?

[lynx]

That&#39;s not really what it means. That setting controls the ratio of FSB speed to memory speed. You CAN oc the memory with this if you really want, but it isn&#39;t much of a good idea.

I want to oc the cpu can I do that?

[Storm]

it depends, do you have a setting for the FSB??? if so, what is it set to, and what can you set it to?

It is a genuine Intel motherboard, so I thought that overclocking was unlikely.

However, here (http://www.motherboards.org/reviews/motherboards/1194_2.html) is some info on overclocking with that motherboard, which suggests you need to do it with software, although it doesn&#39;t specify what.

I can&#39;t find any positive reference to it though, it is probably vapourware.

So I can oc my CPU? :unsure: What is vapourware?

[Storm]

prolly not

and im guessing vapourware is non-existant software....... just a rumor

[silent h3ro]

I guess I can&#39;t. :( http://www6.tomshardware.com/motherboard/2...8/i845e-07.html (http://www6.tomshardware.com/motherboard/20020708/i845e-07.html)

Sorry, I was tired and had to get some sleep.

Vapourware - promised software that turns out to be a lot of hot air. :lol:
