First let me say sorry for a kind of double post, I had a post asking for any good deals on external hard drives but then it turned into a post about that and cpu but i think that thread has pretty much died!

Below is the specs of my motherboard, can any body reccommend a good, cheap cpu that is better then the one i am using at the moment? I do not mind if the cpu is used as long as working so ebay is a good place but having never bought a cpu before i do not know what i need to search for or which cpu is better then others.

Epox site has the following info on that motherboard

http://www.epox.com.tw/eng/products_content.php?ps=28

Bit you're after:-

Support Intel Pentium 4 processors from 1.8GHz to 3.06GHz in mPGA478 socket with 400/533 MHz system bus
Support Intel Celeron processor up to 2.4GHz in mPGA478 socket with 400 MHz system bus

I would suggest going for as fast as you can afford P4 that will work. New egg has 3GHz P4's for $80 new, 2nd hand youll be able to get them much cheaper.

You can see how much faster a 3GHz P4 vs a 2GHz Celeron here:-

Any further improvements is going to involve getting a new motherboard/cpu etc.

Hope that helps

Should be the roughly same, the last one has more cache. But the second one is a regular desktop version and the last one is mobile version. The first one should also be a desktop version. On second thought I wouldn't get the mobile versions, the Epox may not support them.

You need a socket 478 P4 with a maximum FSB of 533Mhz and a maximum speed of 3.06Ghz. This would be a Northwood core. The Northwood core has an L2 cache of 512kb.

If you see a socket 478 P4 with a L2 cache of 1mb and 90nm architecture it is a Prescott core. Your board does not support Prescott.

Two of the Mobile processors you listed were a SL7NA and a SL7NB. The Intel spec finder does not list either processor. I suspect that these were Mobile processors made by Intel probably for Dell.

Most of the 478 Mobile processors require either an 852GME or an 852PM chipset. Although a Mobile socket 478 P4 would fit in the motherboard receiver I feel 99% sure they would not operate.

If your motherboard specs are correct, and the specs on the processor you linked too are correct, then yes, it should work on your motherboard.

As I stated previously in your other post, the socket 478 3.06Ghz. desktop processor with a 533Mhz. FSB was the only P4 with a 533FSB that Intel manufactured that supported HyperThreading.

They were very good processors, and very hard to find.
