How do you overclock compaq?

post #1 of 23
Thread Starter 
I have a Compaq I bought from futureshop not long ago, 2.66GHz celeron, should be pretty decent, right? I spent CN$500 on it.

How do I overclock it?

btw i no its kinda off topic. but i asked sum1 at compaq if i oc and fry the chip have i voided my warrenty and he said no they will jsut ask u to set it back to stock settings. lol luv to see them do that with a fried chip. lol im gonna go for it and jsut say i called and got told a wrong thing (maybe).

First thing to do is go into your BIOS and see if it allows you to change the memory frequency or Front Side Bus (FSB). If it does, raise that value a small amount (say 5-10 MHz), save, and reboot. Continue this process until you get any hint of instability then back off and don't go overboard. There are all sorts of things that may need to be adjusted like voltages and such. For a more complete overview, there is an excellent sticky here:

Take a look at that and if you have more questions let us know.

How do I overclock it?
Proprietary systems like Dell,Compaq,HP etc lock the options in the BIOS which allow you to overclock. Can you adjust your FSB in the BIOS?

You could try software overclocking with Clockgen, but is not guaranteed to work.

The easiest solution would be to get a new:

Motherboard
Power supply
Case
Graphics card as you have onboard.

Unfortunately as the system is manufactured by the Compaq/HP corporation the chance of you managing to overclock the system is rather low. There will be no overclocking options in the BIOS for you to use, so your last resort is to attempt to use software overclocking applications. These would allow you to write values to the Phase Lock Loop chip (PLL). The chance of this happening on your system depends on the exact board that you have on your system. If your board is a Compaq based board then you might be out of luck but if its a Intel motherboard then you may have some luck

Software overclocking applications to attempt to use:
  • Clockgen
  • SoftFSB
  • CPUFSB
Each of these applications may allow you to change the clock speed of your CPU by adjusting the FrontSide Bus speed. However you will need to either know the PLL chip you have in your system or know the actual name of the motherboard. To find the name of your motherboard download PC Wizard 2005 or Everest Home Edition and they will give you detailed information on your motherboard

To check which PLL chip you have in your motherboard have a read of this article as it should give you some nice information http://cpufsb.de/FSB.HTM
When attempting to overclock your system you will need to enter the information, either the PLL or the name of the motherboard for it to detect which chip you are using. Be warned that if you select the wrong board or an incorrect PLL that your system will most likely crash and it may cause physical damage to the PLL chip. So be very careful, if none of these applications allow you to change the frequency then you may be out of luck. You could try and find another application that can write values to your PLL chip or you could try a custom BIOS (I do not recommend this option). Getting a custom BIOS may allow you to get extra options including overclocking options, however if the BIOS is incorrectly configured then it could write incorrect values to your PLL chip and cause the system to crash and as I said before it could actually cause physical damage to the PLL chip which is obviously not very good

Best alternative is to follow Inspire's options and buy new system components. Make sure you get a new graphics card as having an onboard one can seriously cause issues with overclocking because it is tied in with the FSB speed, also increasing certain voltages can damage it. Cooling is a must for overclocking because of the increased thermal output of components when they increase in speed and voltage is increased to them. A power supply is very important as well so you can get enough voltage/wattage/amperature to the CPU for it to operate well at the higher clock speeds. The most important for you is to get a new motherboard of course so you can have overclocking options I would recommend one from Abit, ASUStek or DFi

Guess I can't overclock afterall
I went to the BIOS (took me few tries, it was F2 not del), there is nothing on FSB, or Multiplier, or any of those options that looks like overclock.

So will a new motherboard help? From what I learned those compaq motherboard does not let you overclock? But why?

Everest tells me my CPU temperature is 47C, is that good?

That's about right for stock. Run it at 100% load and tell us what it says.

How do you run at 100% load?

First open up your system monitor (CTRL+ALT+DEL) Go under performance.

Run CPU intensive applications such as Prime 95 and F@H until the CPU usage at the bottom of the task manager says 100% I usually run both to make sure it's 100%. Let it run for about a minute to warm up and that should be your max load temp.
