Best cpu hi all, i want to get the most speed out of this mobo witch cpu is fastest here? TY

Hi Edward,
This depends on the specs of the other mobo. You cannot damage the mobo or CPU by plugging it in and switching on, so the easiest way to test this would be to place it in the other mobo and switch on. If you see a display on-screen it means the processor is compatible with the mobo.
Best wishes,
Graeme.

Unlikely, I would think that the best processor you could use would be a 3.0Ghz or maybe a 3.06Ghz. If you look at the motherboard part number you will be able to find out from the manufacturers what the fastest CPU is. A lot depends on the FSB on the mobo and the Bios version. You need a "Socket 478" processor I think you will find that the processors you are looking at are "Socket 775" ( this is the fitting socket for the processor) .

According to cpu-upgrade, it looks like the fastest processor you can get is an Intel Celeron 533MHz. You can pick them up here for $72

Your mobo rans in Athlon 64 socket 939 compatable processor. The fastest processor there is that you can install in this mobo is AMD Athlon64 4000+ Socket 939 Processor. =)

alright here is your answer from msi themselves. you can use any of the following cpu's on this list.

CPU'S

also here is the manual for your reference
Your motherboard is a socket 939

Manual

i could only fins thease specs for you

AMD Athlon up to 2400+
AMD Athlon XP up to 2600+
AMD Duron up to 1.8GHz

Your motherboard supports 2 different fsb's.
look these up @ cpu-world
you can use:
Intel Pentium 4 processor (478-pin)
- 533MHz system data bus - supports up to 2.8 GHz
- 400MHz system data bus - supports up to 2.4 GHz

Intel Celeron processor
- 400MHz system data bus - supports up to 2.0 GHz CPU speed
and here are the suppoted cpus:

Max speed supported for your mobo is: DDR2-533
You will have to buy (4) 1gb sticks (2gb sticks not supported)
To use all four gigs of ram you need a 64 bit os.32 bit only supports 3gb of ram. Hope this helps!
Here is the specs :

Look for socket A processors and ignore the XXXX+ and focus on the XXXXMHz rating (the MoBo's manufacturer's support site will give you the max processor your Board will handle). Since you mention that your MoBo is 4 to 5 years old, you'll probably better serve yourself to replace the MoBo and processor (you'll be able to upgrade to a much better/faster processor by upgrading both, and shouldn't cost that much more), and probably be happier with the result. You may want/need to upgrade your Power supply while you are at it too.
