Difference between P4-m and Mobile P4
- Thread starter loltim
- Start date
The 2.4 "Northwood" based P4-M is a 35W part with a 400mhz FSB as you said, There are several 3.06 models, two based on the northwood core, with or without Hyperthreading which are 70W parts, and a Prescott version which is 88watts.
All the 3.06's are 533mhz FSB parts. Biggest issue is going to be the cooling, unless the Laptop was designed to support faster CPU's jumping from a 35W cpu to a 70W (or more) cpu is bound to cause some heat issues. Even if dell sold that model with a 3.06 option, it might not have used the same cooling system.
Whatever you decide, do it with care, as some laptop batteries can become unstable when subjected to additional heat especially lithium ion battery packs, and of course if the CPU overheats to much it will just throttle back and end up slower than the 2.4 cpu anyway.

Avoid any mobile prescott like the plague. Have repaired quite a few laptops with 'Northwood upgrades' as the power draw of the prescott caused random overheating and juiced out batteries damaged beyond charge, dead psus and dead mobos due to power regulator failure. The ones i saved at work and for customers are probably still ticking over with the NW mobiles (usually 2.6 and 3.06 models if i remember right).
