Dual G4's don't have ZIF CPUs or sockets. They are proprietary Apple CPU modules, not ZIF. The key concept that distinguishes a "ZIF" is that the CPU has hundreds of small pins that drop into small holes in the socket. It takes no force to insert the pins, instead, a small lever on the side of the socket clamps all the pins simultaneously. No tools are required to change a ZIF CPU, whereas the dual G4 CPU modules are attached with screws, and are not ZIF sockets. If you are still confused about what a ZIF is, look at this, there is a photo of a ZIF socket: <http://en.wikipedia.org/wiki/Zero_Insertion_Force> -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
