DDR3 memory offers higher bandwidth and increased performance at low power DDR3 offers data transfer rates up to 1600 Mbps Lower power consumption of 1.5 volts instead of of 1.8 volts by DDR2 memory Error Correcting Code (ECC) for greater data integrity and system uptime by protecting against errors in memory DDR3 provides an 8-bit prefetch buffer, compared to the 4-bit buffer for DDR2, storing more data before it is needed Integrated thermal sensor on the DIMM module signals the chip set to throttle memory traffic to the DIMM if its temperature exceeds a programmable critical trip point 240-pin JEDEC/EIA standard UDIMM interface Gold-plated leads

Notes: ThinkStation D20 has 12 memory slots; divided into two sets of 6-DIMM memory slots. ThinkStation D20 supports UDIMM and RDIMM memory. For information on RDIMM go to: ThinkStation S20 has 6 slots. ThinkStation S20 and D20: Mixing memory speeds; 1066 with 1333; causes system to operate at the lowest installed speed. When using four or more 1333 are installed, ThinkStation operates at DDR3-1066 memory speed. Memory speed operation is dependent on processor speed. For optimal performance, memory speed should match processor memory bus speed. ThinkStation D20: Mixing of UDIMM and RDIMM is not supported. When using sever or more modules, ThinkStation D20 requires a second processor.
