*Notes:
- Each memory board supports from 128MB to 4GB of memory.
 
- Each board contains 16 slots organized in 4 rows of 4 slots each.
 
- Memory is four-way interleaved requiring ALL DIMMs in a row to be of the same size, type and speed.
 
- The Digital Server 9100/9105 uses buffered DIMMs. The slowest DIMM on the board must be in slot J1.
 
- A maximum of four DIMM memory kits can be installled on a DIMM memory board. DIMM memory kits can be mixed on a DIMM memory board.
 
- Slots must be populated in contiguous order. That is, rows must be populated in a monotonically increasing sequence starting ROW 1- for example, {ROW 1, ROW 2}. An invalid, non-contiguous sequence would be {ROW 1, ROW 3}.
 
- Memory features of the same size must be located in contiguous rows of the memory board. A valid sequence would be {512MB Kit, 512MB Kit, 1GB Kit, 1GB Kit}. An invalid sequence would be {512MB Kit, 1GB Kit, 512MB Kit, 1GB Kit}.
 
- Total Microsoft Windows NT® 4.0 supported system memory across both memory boards is 4GB. In 8-way systems, memory should be distributed evenly across both System Memory Boards. Future operating system release may support greater than 4GB.
 
- All systems must be configured with one 256KB or 1MB LST (Line Status Table) SIMM per System Memory Board.
