I have the Dell Inspiron 1300 laptop, with the Intel 915GMS/910GML chipset (according to CPU-Z). It uses socket 479 and the stock FSB is 400Mhz. I want to upgrade the Celeron M 370 CPU to a more powerful CPU (eg. a Pentium M). I was wondering whether ANY socket 479 CPU will work with this motherboard or only Pentium M and Celeron M? There are Intel Celeron M, Pentium M, Core Solo, Core Duo, Core 2 Duo processors (older model "Merom") that use the 479 socket. Will any of these socket 479 CPUs work with this motherboard? Also a lot (if not all) of the current socket 479 CPUs have a rated FSB of 667Mhz (even the Pentium M (which would work on this motherboard for sure). If I was to install a Pentium M with FSB667Mhz would it run at 667Mhz FSB or would it be underclocked to 400Mhz FSB? Thanks.
