[QUOTE="Kash, post: 401840, member: 23444"] Unfortunately, you are correct. The memory type in the G5 does not match the one in the Mac Pro. The G5 uses 184-pin DDR 400 MHz RAM whereas the Mac Pro uses the FB-DIMM 667 MHz (essentially DDR2 RAM except it's fully buffered compared to normal DDR2 which isn't), which are not pin compatible. Looks like you'll have to shell out money for more Mac Pro memory. Keep in mind that FB-DIMMs need to be installed in pairs. So if you want 1GB, you need 2x512MB and 2x1GB for 2GB of memory, etc. Newegg has some decent prices for FB-DIMMs. A single 512MB stick goes for $52.99, so $105.98 isn't bad for server memory.
