I have a Celeron 600mhz in a socket370 Mobo , its the FCPGA form factor , i wanna know if i can upgrade to a celeron 1.3ghz even though its in a FCPGA2 form factor. my mobo has a 100fsb so it can handle it , so basically what im trying to say is can u put a FCPGA2 cpu in a mobo with a FCPGA cpu in it , also do u need to use thermal grease with a fcpga2 cpu? , im not sure cuz of that integrated metal heatsink built onto it
