View Full Version : to P4 or to P4M
ok i am getting my toshiba A65 in the next week or so and i plan on changing the ****y cely2.7/128k L2 with a P4 since the cely is a desktop cely i tought i would be trap switching for another desktop cely but today i went on Ati website as the onboard chipset is a radeon 7000 igp and when i checked the feature i saw that ati are saying that the chipset supports P4M and celyM
CPU Interface
400 and 533 MHz CPU FSB for Mobile IntelŪ PentiumŪ 4 Processor-M
Supports Hyper-Threading (on HT-capable processors)
In-Order Queue (IOQ) depth of 12
Supports Dynamic Bus Inversion (DBI)
Supports system bus interrupt delivery
On-chip termination of processor interface
now my question is since the cely that toshiba put in it is a desktop cely does this mean that it will only supports desktop chip or will i be able to put a P4M in it
I would think so... but I kinda steered clear of the whole p4 in a laptop idea so i'm not 100% but I would say i'm at least 95% sure...

you are 95% it will only support desktop chip or that it will support mobility chip to
im 95 % sure it will support bolth especially if they are the same FSB and same socket...
what intel chipset do you have? you can't always go off of what another company that makes different products says... i'm pretty sure that's only the onboard graphics not the actual northbridge chipset...
its an ati chipset "ati mobility radeon 7000 igp"

It probably will work, but a P4 will probably put out more heat than the Celly that the laptop is designed for. You might have trouble with overheating which may cause instability.
It will work, the A65 shares a lot in common with the A75. I'm not 100% sure but they are basically the same except for a Prescott in the A75 and Radeon 9000IGP.
You should be able to use a prescott with HT running at 533FSB in there.

but are prescott P4M or P4 cuz thats my question i would like to put in a M chip since they produce less heat

Yes find a Pentium 4 Mobile. They are based off of the Northwood cores. They do not have HT though, but for battery life it is the way to go. I am not guaranteeing it to work but a P4M was designed for a laptop a P4 was not. If you really want HT get a Northwood 3.06GHz, 533 FSB so not that damaging on power and it has HT.
There are 2 P4Ms there's the northwood based on that's got no HT and runs a 400FSB and there's the Prescott based one that's got HT and has the 533FSB. The Prescott one is slightly worse in battery life and hotter.
It might be hard to believe but the 2.8 Prescott would be the one to get, any faster and the leakage is terrible but at 2.8 it's about the same as the Northwood chip but you get HT and a faster bus not to mention 1mb L2 cache.

I did not know that. I learned another thing today.

I didn't even know they existed till my boss bought an A75 and told me to load the company software on it. So I CPU-Zed it and it showed prescott and 533 bus and task manager showed HT.
wow I think I learned something too... diden't realize the prescotts in the lappies where only 533mhz... thought they used 800mhz...
i also diden't realize that ati named their chipsets radeon... that was just throwing me off...
i guess this is what I get for steering clear of those troublesome p4's and going right to pentium-m...

533 was to save power and I believe most of the chipsets when they released the P4M into only supported up to 533. There weren't any 875,865,845 based laptop at the beginning and I know all the IGPs out there were released with support with 400 and 533FSBs only.
ok so i shouldnt have any problem running as the basicly the P4M are only P4 that are tweaked to run at lower temp but the socket and all are the same
Yup... Now I'm 100% sure...

100% is actually 99.9% rounded :p
