overclocking can it be done on a athlon xp 2000 without opening it up

yes it can be done, but their is several things you should know before you start

1) The 2000 isnt the best for overclocking but it is still possible to overclock it

2) The amount you can oveclock it depends on your motherboard, RAM and videocard

3) overclocking reduces the life span of your CPU, and unless you have a good cooler then it could overheat and blow up

4) Your computer could become unstable if you overclock too much

5) when you change what speed your CPU operates at you also have to change what speed yuor RAM runs at

Thast all you should know i think

and this is how i recomend you should do it

your CPU speed is set in your BIOS by the FSB, to overclock it you need to change theses valuse and increase the FSB and then the clock speed will increase, however their are disadvantages to doing this, for example you have to reboot to change it and it takes a long time

so i recomend you use a program called speed fan (http://www.almico.com/speedfan409.exe) its a program that lets you overclock within a windows enviroment, and lets you experiment to how far you can go, it also monitors yuor temps which is handy

to do this you have to fill in your details on the "clock" tab (e.g your motherboard) then click read speed, and it will tell you your current speeds, which should be CPU 133 RAM 133 and PCI 33

Then look down in the list box and select a slightly higher speed (e.g 137 , 137 , 35) test windows for a bit and monitor your temp

then go back and see what the highest you can go to is

You will then have to change change your max FSB in the bios

one more thing, dont EVER try to 'open' a CPU, it will void the warntee ;)

thanks dave

much appreciated

I would disagree with the last word mentioned in #2, your agp/pci bus is untouched if you if you lock it, which is what you'll be doing if you want atleast a 10 mhz OC.

Many newer motherboards would lock the AGP/PCI and also allow you to set the speeds for RAM and CPU independently. On older boards, however, increasing the CPU FSB will force everything to go at faster speeds, which is undesirable.

Changing the FSB is a pretty basic OC way and can be done easily on most boards. For the t-bred family including the XP 2000+, you will need to connect the bridges if you want to get the most out of the CPU as changing FSB will not get you very far because it doesn't allow you to play with voltage multiplier and the Vcore. Many newer mobo's with nForce chipset will automatically connect the bridges on a t-bred so OC'ing a t-bred on these is very easy and you don't have to worry about damaging the CPU when trying to overcome the gaps b/w the bridges with your own hands. :)

Dave,
I'm using the program you suggested above. What is Winbond W83791D and LM75?

Its reading my temps as 126 degrees C. The graph has a flame next to them. The rest of my temps are fine.

Fan 1 is spinning at 10,000 RPMs and fan 2 and 3 are about 5,300 RPMs.

copyright, im just going by my own expienence which is that i have to chane every frequency, as like van said i have an older MB

freakit, i THINK that is your motherboard board model and clock, you have to choose the correct motherboard and then the clock should be set correctly, the 10,000 RPM fan is probley noise from the other 2, which speed fan is picking up OR your motherboard is not supported by speed fan so its just giving you rubbish

heres a list of supported boards

One more thing Van, it may be the most basic way to overclock, but its also one of the best ways to get on to then next steps

alright, also if you have a mobo like asus, gigabyte and some others they inlude their own app which you can use to overclock through a windows enviroment, but the "31337" Overclocked dont use, nor like it, lol..

As I said above, newer boards with nVidia nForce chipset would unlock the T-bred CPU's installed on it so you can overclock the CPU right out of the box easily via BIOS or even through a Windows utility. That's "a dream comes true" for OC'ers saving them time and money to unlock the chip by hands (which is a messy job whether it's done right or not and many times, the modified chips ended up it the trash can because of short circuits).

Although some chips are better clockers than others, thats not to say that this 2000 chip wont do wonders. You wont know until you dry. Yes you can overclock it, how much will depend on what chip it was. Whether it was a Palomino, Tbred A or Tbred B core for example. I got a 300mhz overclock on a palomino core, which are generally the worst clockers of the lot

2) The amount you can oveclock it depends on your motherboard, RAM and videocard
True, though the videocard is completely sepearte beast really. If youre trying to achieve raw Ghz, then the video card will make no difference

3) overclocking reduces the life span of your CPU, and unless you have a good cooler then it could overheat and blow up
A decent cooler would be required certainly. It wont blow up, more burn up and die a thermal death. It will shorten the lifespan of the cpu, but chances are you would upgrade before it died anyhow

4) Your computer could become unstable if you overclock too much
Yes but then that is half the 'skill' and 'fun' of overclocking.

5) when you change what speed your CPU operates at you also have to change what speed yuor RAM runs at
this is true, although some motherboards allow the ram and cpu to run out of sync, ie the ram to run at 4/5 of the cpu etc etc. For example a 200 fsb chip would need pc3200 ram rated at 200fsb. Pc2700 ram rated at 166 would be no good, for example

I would advise against using any 3rd party overclocking tool and use the bios for all overclocking needs. You cpu speed comes from the multiplier x fsb (front side bus). In my sig, my chip runs at 2300Mhz, with a multiplier of 11.5 and a fsb of 200. It is far easier to adjust these in the bios than elsewhere. Upping fsb in this way may require you to put more voltage through the chip, thus more heat generated, thus a decent heatsink needed etc etc etc. Generally the best way forward is to max out the multilpier of the chip by running the fsb low, then once the max multiplier is established, raise the fsb as high as possible to achieve the maximum possible clock

i have the asrock k7vm4 mobo, overclocked amd 2 gig cpu to 2.8...ran but not very stable..all is well at 2.6 altho i did put a larger cooler on, just in case. running 512 drr 2700 mem
