Ok, need help. I wish to overclock a old compaq with a p4 1.7gh, its just something to try it on for the first time. so heres what i need to know... 1) Can I do it with my PC. 2) what kind of programs do i need or do you do this in the bois or something?? 3) what are the dangers, and what do i need to be careful around. if someone could just walk me through it that would be great. I do know my way around a little, not a complete moron. lol. just need some help with this one. thanks.

1, If it's an old P4 in an old Compaq then the answer is no.

2, You should use the BIOS.

3, Watch the temperature, take it in small steps and keep testing for stability. Don't be over-zealous with the voltages because that will cause damage if you pump too much power into it. If you think you've got a stable overclock then stress test it with something like Prime95 for a long time (overnight or something).

Can your PC do it? It all depends, are there any FSB speed settings in the BIOS?

I would not mess around with any voltage settings until you really know what you are doing.

You won't get far without it on a P4. And really you won't cause any damage unless you decide it's a good idea to set it to like 2V...and I doubt his mobo will even allow for voltage adjustment, let alone to that degree.

Look you two are way over my head with this sending more volts to the p4 and all this. what i did understand is the FSB and thats 800 and its rambus ram. But if theres anyway at all i could just try it that would be good enough for me.

Look through the BIOS and see if there's anything about FSB Frequency. Could also be called other things, such as CPU Frequency, CPU Clock, External Clock and probably others.

It's hard to tell you where to go because it differs between different types and versions of the BIOS.

Here's some examples from Google,

http://www.hardwareoc.at/software/8rda-bios-4.jpg http://bits.webhs.org/blog/bios.gif http://www.driverheaven.net/reviews/AV8Review/Uguru%20Bios.JPG

As for voltages...uhm where to start. As you push a processor harder it will become less and less stable and you'll start to encounter all kinds of funky shit from crashes to reboots to the system not even starting[color=red]*[/color]. The way to counter that is to give the processor more power (increasing the voltage), in the same way that if you turn a big speaker up it needs and uses more power than a little speaker playing quietly. Now the problem with upping the voltage is that processor are inefficient meaning that it creates more heat than it would at a lower voltage, which can be dangerous in the long run. And if you crank it up too far you can wreck the chip, just like how you can blow speakers by putting far more power into them than they're rated for.

But in case I'm scaring you, you'd need to seriously cock it up to do any damage by putting in too much power, and it's easy to keep an eye on the temperatures (and if it's overheating it'll become unstable anyway, so you'll know).

[color=red]*[/color] Make sure you know how to reset your BIOS before you overclock anything. Look for a watch battery on your motherboard, if you remove that for a while the BIOS will reset to the default values; so if you render your PC unusable by setting it so high that it won't even switch on without crashing, all you need to do is reset it by removing the battery and then putting it back in.

A lot of people seem to suggest leaving it out for a while (say 30 mins) but with my mobo it resets it instantly.

There should also be a jumper that will reset it, but there will be lots of jumpers on your mobo. Only reliable way to find out which one it is is to use the motherboard manual, which you won't have with a Compaq. It's easier to use the battery IMO.

Oh, and come to think of it, a P4 uses a Quad Pumped FSB. Unless I'm mistaken the actual FSB speed for yours is 100MHz, the Quad Pumped bus speed is 400MHz. Only Pentiums later than the Northwood C have the 800MHz Quad Pumped bus (200MHz FSB) and your one predates those by a couple of years.

well thats PERFECT!!!! Thank you Archaon, I know that was overclocking 101 in a nut shell but I really have a much better understanding of this now. thanks again. One last thing so there are mobo and bios that are easier to overclock than others??? or is it all in the bios not the board or do those go hand and hand?

1. Which type of BIOS you have depends on the board. The main three types I've seen are AMI, Award and Phoenix (though I think Phoenix makes Award)

AMI - http://www.techpowerup.com/reviews/ASRock/775XFire-eSATA2/images/b_bios.jpg Award - http://www.viaarena.com/images/articles/3/watermarks/install%20001.jpg Phoenix - http://ice.he.net/~hedden/images/boot_seq_Phoenix.jpg

As you can see they're not really much different, just different layouts. I prefer Award but you don't have a huge amount of choice in the matter - your board has a particular type of BIOS and that's it, you can't change it.

2. Unfortunately not all boards have the same features, even if they use the same BIOS. As a rule you need a decent board to get all the features you need to overclock properly, which is why I said it's unlikey you can do much in my first post; because as we know, pre-builds don't generally come with decent motherboards, and Compaq is one of the cheaper brands around so it's even less likely.

For example, in this machine I have an ABIT IC7-Max 3. In my opinion it's the best motherboard available for my socket 478 P4 processor. Other people either agree with me or say it's bettered by an ASUS model (which I've forgotten anyway), but either way it's one of the best around. If you click the link (the only underlined bit) in my sig you'll see what I did to my 3.4GHz P4 with it.

In contrast I have an ABIT SG-72 in a machine downstairs with an older 3.06Ghz P4. It has no overclocking features. At all. All it will let you do is change between three pre-set speeds for the FSB, 100MHz, 133Mhz and 200MHz. Which are the standard speeds for all the processors it can support. So you could technically overclock a 133MHz FSB processor by putting it on a 200MHz FSB, but it wouldn't have a hope in hell of working without a lot of extra power (63MHz on the FSB is a big jump) - and the SG-72 just doesn't give you that flexibility.

Both use the Award BIOS. The SG-72 cost me £30 new 2 years ago, whereas the IC7 set me back £120 almost 3 years ago.

3. (conclusion, really) So really the type of BIOS it has doesn't matter much, the only real differences are the layout and wording. What matters is which features are available and which are locked. It's not relevant for this because it's an old system that you already have, but when buying a new motherboard the only way to tell is to read up on the motherboards that are available.

Attached is a pic of the CPU/RAM/Power settings in a decent overclocking motherboard. I can't be bothered to take a pic of the SG-72 screen, but it basically lets you choose betwee 100Mhz, 133Mhz and 200Mhz as I said, and let's you see what speed the CPU and memory are running at. But not adjust them.
