Memory Options

The server provides double data rate (DDR) synchronous dynamic RAM (SDRAM) that can
improve memory clock speed to at least 333 MHz. It activates output on both the rising and
falling edge of the system clock rather than on just the rising edge, potentially doubling
output. The server features the following advanced memory technologies:
•
Support for up to 16 GB of industry-standard PC2700 registered ECC DDR SDRAM
memory
•
Advanced ECC memory for single-bit detection and multi-bit memory error correction
•
Dual-channel memory architecture

Memory Guidelines

Bank 1A must always be populated.
•
DIMMs must be installed in pairs and starting at the bank closest to the processor.
•
All DIMMs in a bank must have the same part number.
•
DIMMs on different banks can be of different sizes.
•
Processor 2 must be installed before banks 2A and 2B are populated.
•
If processor 2 is installed, it is recommended that bank 2A be populated before
populating bank 1B.
