DDR3 DIMM Memory

DDR 3 memory should be showing up soon in stores. DDR III is the third generation in the Double Data Rate series. DDR3 runs faster than DDR2 which tops out at 800Mbps. DDR3 will double that transfer rate and consume less power because it operates with 1.5 volts instead of 1.8 volts.

DDR4 is not due out until 2011, while DDR2 arrived in 2004. I've seen that the AM2 processor socket from AMD does not support the DDR3 memory. Also that the next new processor from AMD, called AM3 will not be released until 2008. However it would appear the an AM3 processor will work in an AM2 socket-ed Mother boards. Here are a few links:
