EETimes.com - Going green with DDR3 memory: "Industry experts concede that about 82 percent of the $500 million bill for a typical large data center is going toward the facility's mechanical and electrical infrastructure.
For the data center server, one contributor to this higher power density is the memory subsystem. A typical 1U server requires a 600 to 1,000-W supply for its power. These high-end servers used in data centers support between 16 to 18 DRAM slots. On a DDR3 (double data rate 3) system, each single slot draws on average 9 W, using a typical 2-Gb module. The total memory subsystem power is around 144 to 162 W, which is nearly 25% of the available power for the system. Multiplying this by the power draw of 40,000 to 80,000 servers in a typical data center translates to between 5 to 13 MW (megawatts), just for the memory subsystem. Over 13,000 American homes can be powered using that same amount of power"
