You can replace memory modules in any 8000 Series Server Module (blade). Depending on the blade type, the configuration and population order might differ. The X8400, X8420, and the X8440 Server Modules ship with dual in-line memory modules (DIMMs). The X8450 Server Modules ships with Fully Buffered (FB) DIMMs. For more information about memory module configuration and population order on a server module, see Memory Module Configuration and Population Order.
