want to upgrade 1.6ghz p4-m

[jorwex]

I have a dell 2650 inspiron laptop with a 1.6ghz p4-m socket 478 w/ 400mhz fsb. I want to replace the chip with a pentium m chip. I want to know whats the best chip I can put in to the board. I saw that there were some with the 400 fsb/ 478/ and a 2mb l2 cache. Basically I want a pentium-m with around 1.6ghz speed and the highest l2 cache possible that is compatible, please help me out in picking a chip.

any advice?

Pentium M will not work in your laptop - it requires different kind of socket.

Ok let me rephrase, my chip is the SL5YU would a SL7EG work seeing as it has all the same specs except the l2 cache

P4-M and PM are different sockets. If I am correct, all P4-M's are univeral to their own sockets just as long as one will work with the socket it's replacing.

478=PM
479=M

mobile 478's will not work on desktops unless it's a special board or with an adapter that the board will support.

your laptop should run any P4-M just fine. why not contact your manufactur's website?

Let me rephrase it too - both Pentium M and P4M processors require socket 479 motherboards. Pentium M is in 478-pin package, and P4M is in 478-pin package, but the packages have different pinout! So, Pentium M will physically fit into your socket, but it's not electrically compatible with it.

enlightening, thank you I guess i will stick with pentium 4m

See if you can upgrade to Pentium 4-M 2.6 GHz - it has the same FSB, core and core voltage as 1.6 GHz processor, and works in the same socket.

I don't think the performance gains are worth the money.

Even if you upgrade the MHz and cache, your tasks will still be held back from DDR1 and the other old laptop technologies onboard.
