The title pretty much says it. Any thoughts on the feasibility of swapping the 1.2Ghz (533FSB) U7600 for 1.5Ghz (667FSB) L7400? I realize the TDP difference, but figure rmclock can help offset that (and help the battery too). The FSB is set by the CPU, correct? Should that cause problems? Thanks for any input/thoughts.

Theoretically, this may be possible. However, the U series CPU is probably soldered, not socketed (which reduces notebook thickness). In theory, the Core / Core 2 CPUs are available in 4-MB and 2-MB, 478-pin Micro-FCPGA packages as well as 4-MB and 2-MB, 479-ball Micro-FCBGA packages. PGA means pins (ie socket) while BGA is soldered.

The clue to see what you have seems to be number. CPU-Z reports the T7300 in my Zepto 6024W (which I know is socketed) as "Socket P (478)" whereas the Sony G11 (U1500) has the package "Socket 49 mPGA" (I think CPU-Z means mBGA).

Depending on your usage, you may not notice a difference.
