Upgrade Pentium M 1.4 to Pentium M 740 will it work?

[master7045]

basically I want to turn my Dell Inspiorn 8600 into a more able gaming laptop. I'm planning on replacing the hard drive w/ a 5400 Hitachi 60GB and was wondering if this (pentium upgrade) will make much more of a difference. I have found them on Ebay for a decent price and wanted to make sure of my purchase. Thanks in advance

From my observations of Intel's releases of CPUs and chips, I've come to know that new CPUs don't come w/o a new chipset to complement it. Here are some things I can think of off-hand that you can check over...

1) It uses the same socket
2) It supports 533MHz FSB

I dunno what chipset is used on your laptop but Intel always seem to come out with a new chipset when they release a new CPU "line". In this case, the model you mentioned in the title indicates the 533MHz line. The one I have is 400MHz and is part of the Centrino package (855GM chipset). Yours may be different since you mentioned gaming and the first thing that came to mind was ATI and NVIDIA. A better description would better assist us in helping you determining whether the new CPU would actually work with your laptop.

8600 has the 855GM chipset; that means 400FSB Pentium M CPUs only. The 740 will not work because it is a 533FSB CPU...well actually it WILL work, but since the 855GM chipset has a 400FSB max, it can only run the CPU at 1.3GHz instead of the rated speed of 1.73GHz.

I have the ATI 128mb vid card, and I assume that it came w/ the 855PM chipset, thats what i read at Toms Hardware website, so thats the conclusion that i came up with, is just keeping it to a 400FSB Dothan chip and I should be good. Is that correct?

My current system config is:
PM 1.4 400GHz
ATI Mobility Raedon 9600 Pro Turbo
768 SoDIMM (planning on upgradeing to 1GB very soon)
Fujitsu Vesta 40 + (also, plan on switching to a 60 GB, 5400rpm HDD)
Dell Wireless 1450
I am not positive on the chipset, but like I stated before, i think its the 855pm


also, if i still havent given enough info, let me know what else to list

My current laptop has the same Pentium-M 1.4GHz you have. A processor at 1.7 or 1.8 GHz will actually be a very nice speed increase. You should just pick up one of the 400FSB processors from newegg or something. Those should work great.

so a P-M 735 would do the trick? i just found one for cheap NIB.
