R40e Upgrade

[zetlaw]

i have IBM r40e type 2684.
after an hard-drive upgrade and memory it still extremely slow so im thinking of upgrading it's CPU. the corrent CPU is Celeron 2000 mhz.

my question is what CPU can i put instead of the celeron and if it will improve performances

allso i noticed that the celeron is not using the speedstep technology if ill upgrade to pentium cpu it will support ? or the motherboard is not capable

thanks you.

The board that you have will support P4M CPUs, I'd go with 1.6/1.8/2.0 for pricing reasons, since these can be found for about $20 around here...

I believe that there's a topic regarding this written by forum member kajencik who installed P4M 1.6 in his R40e, you may want to use the "search" function and look for it...

And yes, P4M will definitely perform better than your current Celeron. Speedstep should work on your board once the CPU has been changed.

thank you for the useful information. i found on ebay 2.2 CPU for 25 $

im hopping that this CPU will speed up the computer becaus it's extremely slow. that celeron CHip is horobol.

my main system is an Amd Sempron 3100+ and it's great it allmost get the same performance as the Athlon64. but that celeron is like Pentium 3 800.

Hello, I did indeed the same replacement as you are planning to do, In my case the upgrade was from 2,4 celeron to the 1,6 Ghz P4-M, I didn't require much speed, as it only my secondary laptop for internet browsing, so I prefer it to be cooler than powerfull. I can say that the celeron is really horrible thing, I think the main problem is its only 256kb L2 cache compared to the 512kb of the P4-M, but I can say that despite the 800MHz difference, the P4-M is at least the same, if not more powerfull than the original celeron. Oh, and the speedstep is working well, I use NHC to manage it on all of my thinkpads.
