Hi I was thinking to upgrade my old Asus laptop into Pentium M. Here are the details of the motherboard.
Laptop Model – Asus A6R
Motherboard brand– Asustek Inc.
Motherboard Model – A6R
Motherboard Chipset – RS400/RC400/RC410
Package – Socket 479 mPGA
Southbridge – SB400
Bios version – 213

May I know which of the following mentioned below are the possible fastest upgrade option based on my laptop specs before I will buy the CPU at ebay???

My Asus laptop Specs as follows:
Intel Celeron M ( Dothan)
Frequency - 1.6 GHz
FSB – 400MHz
L2 Cache size - 1 MB
Socket 479 mPGA

Upgrade option 1
Intel Pentium M (Banias)
Frequency - 1.8 GHz
FSB – 400MHz
L2 Cache size - 1 MB
Note – FSB and Cache size are the same values as my laptop.
The frequency though is 1.8 GHz only.

Upgrade option 2
Intel Pentium M 765 (Dothan)
Frequency – 2.1 GHz
FSB – 400MHz
L2 Cache size - 2 MB
Comment – My Asus laptop cache size is 1MB only.
I don’t know if this 2MB cache size could run swiftly.

Upgrade option 3
Intel Pentium M 780 (Dothan)
Frequency – 2.26 GHz
FSB – 533MHz
L2 Cache size - 2 MB
Comment –My Asus laptop FSB is 400MHz only.

I don’t know if this 533 MHz frequency could run swiftly.

Finally, If there’s other upgrade options besides the above mentioned you may suggest pls let us know. Thanks in advance for your help. Cheers!

I can't find the 479 socket models for the last 2 you mention in that link.

those links were only to show you the detail specs of the Pentium M. I'm sure the Celeron M is the same socket as Pentium M....Any idea what's the possible fastest upgrade option?

There's also Core2Duo for that socket. You should find out what processor your laptop's bios supports with Asus to be safe. It's probably listed in their homepage somewhere.

Edit: 400mhz appears to be your cpu's FSB and not the highest your chipset can support.
