Intel Pentium m 770 processor

Specs: Windows XP

I'm looking to upgrade the CPU on this old dell laptop. currently i have a 1.7Ghz pentium M.

i know my options are incredibly limited but i would like to upgrade to a 2.1Ghz pentium M 770, but im not sure if its compatable. it has a 533Mhz fsb, whilst i think the laptop only has 400mhz fsb. will this be an issue?

i could go for a pentium M 775 (also 2.1Ghz) which has 400mhz fsb, but on ebay these are 2-3x the price of the 770

Thanks for any help

The 1300 does support 533MHz CPUs.

The M-770 should drop right in there. Like all P6-based CPUs, the Pentium M really shines on a faster front side bus, so the 2.13/533 part should give you a nice boost.

But, if you're willing to take a walk on the wild side, you could overclock your current CPU to 2.26GHz. The Pentium M pin mod forces your CPU to identify itself to the motherboard as a 533MHz FSB part. Nearly all Pentium M 735s have absolutely no problem running at 2.26GHz. I managed to get a P-M 780 to run at 2.82GHz without extra voltage on a desktop board (BIOS overclocking).

Cooling won't be a problem, as the Inspiron 1300 was built to take all models of the Dothan Pentium M, including the 2.26GHz M-780. Your battery life will be slightly shorter--at 2.26GHz, your CPU will draw 6W more than it does at 1.7GHz.

Here's a detailed guide with pics.
