Will any speed of the same kind of CPU work in a motherboard? Like my dad has a Dell with a AMD XP 2.5 (I think) & I have a AMD XP 1.2. If we switch I know the faster one will work in mine, but will the slower one work in his?
 
If its running an XP2500 Barton at stock then the board can definitely do 166MHz FSB so you could upgrade it to at least a 3000+ 166FSB chip, check the motherboard make with a program such as si soft sandra or everest and then see if it can support a 400FSB...if it can then your good to go upto any socket A chip, so upto 3200+.

They didnt make an XP 1200. XPs started at XP1500 (1333MHz) and on the 133FSB went upto 2600+...download CPU-z and check whether its an XP or a thunderbird...likewise check what motherboard you have and see what FSB it supports maximum. Some older socket a boards could only support tbird/duron spitfire/morgan chips and system would work happily with a slower CPU, no problem there but it depends what the highest CPU your motherboard will take as to what you can upgrade it to.

hope this helps.

Cool, so a switch should work. I can have up to a 3000+. When it boots up I am sure it says XP 1200, oh well if I am wrong no matter. SiSoft Sondra will tell the right info right? Well at Memory bus speed/front side bus speed it says x2 133 (266 MHz Data rate), that is FSB right? How do you see what your current memories FSB is?

download cpu-z and click on the cpu tab and then the memory tab to see memory frequency
the above program will tell you the type of processor and memory speed.

If it says XP1200 im guessing you have a cpu with a multiplier of 12x so possibly a xp1900 really but maybe the fsb isnt really at 133? but at 100 causing it to run underclocked.

It seems you have an Athlon MP 1200+ then...strange though - if thats a single processor system why is there a multi processor enabled CPU in there?

Its meant to run at 12x100=1200 but the multiplier has been lowered and the FSB raised to 133MHz making it faster than before..so its all good.
 
basically your best bet is just to try it out, you shouldnt be able to harm either chip by just trying, they have safefty features to stop them dying, your bios should also recognize a new chip, plus it will be good if you get decent cpu, i feel sorry, ure not using xp and you have Mozilla (the non-firefox version)

Dell have only just recently started using AMD in their systems so it will be an socket AM2 K8 of some description.
Different socket from an XP 1.2 for starters ...
 
Oh crap the other system has a AMD XP 1.8, so it won't work for quake4 anyway, so maybe getting a new board would make more since the buying a new CPU & memory.
