How to determine fsb

[Guest]

Hello,
I have a Sony Vaio with Intel T4300 processor, whose FSB speed is 800 MHz. I want to replace this processor by a T9900, which has FSB speed of 1066 MHz but really do not know if my Vaio supports T9900 or not. How can I know if my laptop support T9900?
Thanks a lot.

Hello and welcome to the forums
Whats your laptop's model ?

You'll also have to figure out the heat output of both chips. If your T4300 is a 45W chip and the T9900 is a 68W chip I wouldn't do it. The cooling setup for your laptop can't handle the extra heat.
