The BIOS assesses the SDRAM size and speed using the serial presence detect (SPD) data structure programmed into an EEPROM on the DIMM. Memory size is 16 MB to 1 GB. DIMM board memory size can be mixed but must be either all unbuffered or all registered. Slot vacancies are allowed.
The server board supports the following memory features:
