R40 Celeron CPU Upgrade?

[rtellison]

I apologize if this is in another thread. I have a R40 with a 1.8 Celeron. Has anybody had success upgrading the CPU? If so, what will it handle?

Up to a 2.6 Celeron or P4-m. You will probably want the P4-m unless you plan to keep it plugged in. Reason is the P4-m supports speedstep, down to 1.2GHz to save battery/ reduce heat. Only thing is that they are awfully expensive to procure.


My 2.2 GHz P4-m cpu is coming soon (hopefully tomorrow). If you like I can document it for you

I've got the 1.8 Celeron Mobile as well on my R40 (2682-NU2). I took the thing apart a few days ago just to get a feel of things and to apply some arctic silver which will just get cleaned off with the new cpu.. lol

Just be careful to note if your keyboard has the four retaining clips on the front edge. The manual does not say this and I broke the mouse button doing so Some glue tempoarily fixed it but I have a new keyboard on order.

Thanks for the info. I've built many desktop systems over the years but I haven't modified a lot of laptops. So, I'm not up on the different mobile chips. From what I understand, the R40 socket is 478 pin?
I saw a P4 M 2.2 Ghz 400Mhz SL6J5 on the web. Would that work?

Yeah, 478 micro or whatever.

I got the SL6VB which appears to be identical to SL6J5 other than the stepping. They even have the same part numbers.

I was sorta hoping that it would arrive today so I could install it

Thanks!
