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
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.
