Server makers are generally willing to pay a premium for the increased performance of new memory chip technologies, while a sluggish PC market this year means vendors are less willing to trade up from DDR2 (DDR, second generation) chips because they're much cheaper.

DDR3 memory chips boast several improvements over DDR2, including twice the system performance, speeds up to 1,333Mbps (Megabits per second) and using at least 60 percent less power, Samsung said.

Intel plans to launch two more DDR3-only chip series in the second half of this year, according to a joint statement.
