AMD Duron Compatibility

[Hen_Dawg]

I want to upgrade the CPU in my parent’s machine. It’s a very very slow AMD Duron 700Mhz.
I know the Durons go up to 1800Mhz and I’d guess getting one of those or even a 1600Mhz would be a noticeable help, and they only cost £20.

My main question is do all Durons work on the same motherboards? Or is it possible a faster 16/1800Mhz chip will be incompatible with the old Compaq mobo they currently have?
Also would they still be OK with the same tiny Heatsink?

Thanks

Here is the PC in question? Can I fit an Athlon XP in there? Basically I looking for the best CPU i can put in there without further upgrading. Expect the PSU is fine but I've got a spare anyway.

Thanks all for the knowledge.
It is some kind of compaq presario, not too hopeful bout compatibillity cos it really feels old. The 3:05 min 1M Super-Pi score it got shows it's speed
I'll get a look at the PC as soon as I can with belarc advisor.

And thanks for the MM spot meatloaf

OK Belarc Advisor tell me this:

System Model:
Compaq Compaq PC (yes twice)

Main Circuirt board
Board: Compaq 06E4h
Bus Clock: 100 megahertz
BIOS: Compaq 786K1 09/29/2000

That's all that seems to be relevant, no further mention of chipset.
Does it shed any more light on it?
