Memory options
Minimum memory requirements
•Two DIMMs must be installed in bank 1 on the processor memory board in slot two.
•All DIMMs on a processor memory board must have the same part number.
NOTE: Processor memory boards in slots 1, 3, and 4 can be installed without memory. Certain application programs run more efficiently if the DIMMs are balanced across all processor memory boards.
Memory population guidelines for processor memory boards with eight DIMM slots
•DIMMs on different processor memory boards can be of different sizes.
•DIMMs on the same processor memory board must be of the same size and have the same part number.
•DIMMs must be installed on a processor memory board in pairs and in bank order.
•DIMMs must populate three or fewer banks on a memory board with PC2700 DIMMs to maintain a memory clock speed of 333 MHz.
NOTE: If all four banks (eight DIMM slots) are populated with PC2700 DIMMs, the maximum memory clock speed will be 266 MHz.

Memory population guidelines for processor memory boards with four DIMM slots
•DIMMs on different processor memory boards can be of different sizes.
•DIMMs on the same processor memory board must be of the same size and have the same part number.
•DIMMs must be installed on a processor memory board in pairs and in bank order.
NOTE: PC3200 DIMMs are only supported by processor memory boards with four DIMM slots.
