T40 CPU Upgrade
T40 CPU Upgrade
How does one get a Pentium M 2.0GHz (533MHz FSB - Dothan) to run at full speed in a T40 which has a FSB of 400MHz? I have the latest BIOS and IBM embedded chip updates.

It's not a good idea to use a chip with 533Mhz FSB with a T40. There are chips with 400MHz FSB availables such as P-M 755 (2.0GHz) and P-M 765 (2.1GHz). I would use one of those instead.

No it will run but at a lower speed with a 400fsb, so it is not a good upgrade.

Its not possible. The i855PM does not support the voltage signaling of the 533FSB chips to boot up at 533FSB. Im sure it would be stable if it was supported, but it is unfortunatly not.
