Memory Options
The server provides double data rate (DDR) synchronous dynamic RAM (SDRAM)
that can improve memory clock speed to:
•
•
•
•
•
•
At least 266 MHz with PC2100 DIMMs
At least 333 MHz with PC2700 DIMMs (2.4-GHz server models and above)
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 industry-standard registered ECC DDR SDRAM memory
— up to 48 GB at 333 MHz with PC2700 DIMMs
— up to 64 GB at 266 MHz with PC2100 or PC2700 DIMMs
Dual-channel memory architecture
Minimum Memory Requirements
Two DIMMs must be installed on the processor memory board in slot 2.
All DIMMs on a processor memory board must have the same part number.
NOTE: Processor memory boards in slots 1, 3, and 4 may be installed without memory;
however, this may not result in optimal performance.
