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
