Memory
The system board contains six 168-pin DIMM slots each supporting 72-bit ECC (64-bit main
memory plus ECC) registered SDRAM DIMMs (PC-133 compatible). Memory is two-way
interleaved and partitioned in three banks. You may install a minimum of 128 MB (64MB x 2) and
as much as 6 GB.
The controller automatically detects, sizes, and initializes the memory array, depending on the type,
size, and speed of the installed DIMMs, and reports memory size and allocation to the server via
configuration registers.
✏
NOTE
Use DIMMs that have been tested for compatibility with the server board.
