Hi everyone. My Acer Aspire 1662WLMi laptop has a P4 Processor 3GHZ (478 Socket), FSB: 800MHz, Chipset: Ati IGP9100. As the CPU gets too hot, and its thermal behavior is awful, I would like to upgrade the Processor. Is it possible to replace it with a Pentium M 740 Processor (Socket 478), or would be a problem with the motherboard chipset (ATI IGP9100) :?:

Thanks :lol:

I don't believe it will work. The Netburst CPUs are entirely different in VRM than the Pentium M-class processors.

You can always try cleaning out the notebook and re-seating the HSF assembly with better thermal material, and perhaps one of those notebook cooling pads.

It may be possible, got to research your notebook though

If you pay for the shipping I can overhaul it for you.

What do u mean (KillerNotebooks)? To kill my notebook :D. I have already cleared the fan, and applied new thermal paste. In fact, I have used the Arctic Silver 5. However, the starting CPU temp remains the same i.e. 74C. As a result, I am planning to change the CPU. The question is if I can use a Pentium M processor, instead of a Pentium 4, as the first has better thermal behavior. The socket is the same (478), however I don't know if I will have problem with the m/b chipset or the bios.
