Hi, I have a ASUS 8S-X mobo which has a 939 socket for the CPU and I have XP
Proffesional SP2 installed. Now I have an AMD Athlon 64 3200+ 939 Venice CPU
installed, works ok. A good friend of mine is changing computer and therefore
I have the possibility to get an AMD Athlon 64 X2 4200+ 939 Manchester
Dual-Core CPU from him to replace my recent CPU.

I don't know so much abot theese things but I've read that my mobo supports
Athlon 64, Athlon 64 X2 and Athlon 64 FX CPU:s in its datasheet.

But I'm wondering how my XP-installation will work after the switch.
Will it work at all? Do I have to make some configuration? Do I have to make
a complete re-install of XP?

Many thanks in advance !

After the cpu is installed...
have a look in device manager.

Now look in "Computer" to see if the dual cpu is recognized.
If it is...there is nothing else you have to do.

If it ...however...says single core cpu...

right click on it and opt to "update driver"

to: acpi multiprocessor PC

You may have to reboot...but after that you should be all set.

Note: for "normal" tasks such as web browsing etc...
you may not be able to notice any difference...
but if you use some heavy apps that can take advantage of the dual core
(such as CS2) you wll see a very nice difference !

Another poster gave you most of the information you needed. (I expect that
XP will automatically detect the new CPU the first time you boot with it in
place. I upgraded to dual core on an A8V Deluxe, and that was what
happened.)

Make sure that your BIOS version is new enough to support the processor:

Unfortunately, I don't know the AMD code name vs. official processor
revision. Maybe you should update the BIOS to the latest available.

I swapped out a Celeron 3Ghz for a dual core (not core duo) 3Ghz and XP
recognized and uses it just fine.
This particular board won't support a cure duo or I would have gone the
extra for the better CPU.
But the extra onboard cache on the dual core vs. the Celeron makes it
perform better than the Celeron ever did.
For the $59 the (outdated) dual core cost, I'm much happier.

Note that depending on how many changes you have previously made, the
procesor change may trip reactivation of Windoes XP. The change you are
proposing counts as 2 changes out of the permitted 4 (1 change for processor
type, the 2nd change for processor serial number).

Thank you all for the answers!
