Processor Upgrade

[LtTPfan]

You bought Mobile Intel Pentium 4-M processors, which are compatible with the Intel 845 chipset, while your T41 has the Intel 855 chipset compatible with Intel Pentium M processors. Intel Pentium M processors are not the same as Mobile Intel Pentium 4-M processors. The former are better, they have more cache and operate at lower voltages and temperatures, and have other speed enhancements.

While the CPUs you bought may have a faster speed rating, even if they did work in your mainboard, you would find that your machine would actually slow down.

Hi all,

I'm trying to upgrade the processor on my T41p. I currently have a 1.5 and bought these processors from ebay.

I've followed all the instructions and updated my BIOS and Embedded Controller to the latest. Fitting the processor was simple and I applied a bit of Thermal Compound as well.

However when my T41p starts up, all it seems to do is sit there and do nothing. Just a blank screen and the fan whirring away. No Hard Disk activity or anything!

The processors I tried to upgrade with were:

MOBILE INTEL 1.7GHZ PENTIUM 4 512 LAPTOP CPU SL6FG

Intel Pentium 4 Mobile 2ghz/512kb CPU Processor SL6FK

Am I doing something wrong or missunderstanding anything?

The only thing I've noticed is that part numbers on the processors I've bought is RH80532, whereas the part number on my 1.5 processor is RH80535. Don't know if this means anything.

Anyhelp would be appreciated.

well .. thats because they're pentium 4 cpu's and probably not supported by the chipset. But dont worry. Theyre not any good cpu's anyhow.

but a T41p with an 1.5ghz? what type number is your machine?

I think you got the wrong CPU, a P mobile you should be using has 2M buffer/cache not 512K. a 2G P mobile with 2M cache normal price costs US$350 or more each. even a used one will cost at least $250..

Just a thought, others will confirm if I am right..
