Processor running at half speed.

[TG2]

k got the chip out and it is intel 01, pentium 4, 2.40ghz/512/800, sl&wf malay, l317a953, m320a668, 0469.

I think you might have an incorrect digit there.

The "SL & WF" There is a P4 2.4 cpu that is spec SL6WF ... and that processor would match the rest of your numbers ... 2.4 GHz ... 512 cache, 800 ...

The first part ... easy to recognize 2.4GHz ... that's the CPU running frequency. The second part of the number 512 ... is the amount of "L2" Cache memory .. the third part of the number 800 ... means 800MHz Front Side Bus (FSB)

Your system board is not capable of generating an 800MHz FSB, its only able to do 400MHz.

You need 2.4/xxx/400 I put XXX because they make 1024 (1 meg) cache P4's, they also make 512k and 256k cache models too.

Wiki isn't always right ... but in this case it gives you a better look across the P4 line

and if you follow one of the SL numbers in the first "Northwood" section (like SL65R .. and not the second northwood, thats the Pentium 4 HT section)... you'll get to Intel's ARK page
http://ark.intel.com/Product.aspx?spec=SL65R
and again on the right side you'll see there's a bunch of processors that are similar in specs...

and here is the ARK page for all the P4 400MHz FSB processors (note you can't use the ones that have "YES" in the Embedded column, they are soldered processors, not 478's)

See if the reseller you purchased the processor from is willing to take the CPU back in trade for one of the correct model (400MHz FSB) ... if not, you'll probably want to list it on Ebay or some such, and then will need to order the correct model CPU for your system board (400MHz Front Side Bus)
