Entering the generation of green datacenters, most IT organizations are looking for newer and better modules to supply the needs of datacenters for the future. Study shows that 60% of (pre-2005) datacenter facility will not be able to supply the needs of future demands. With STEC’s 1.5V DDR3, datacenters are able to increase performance and reduce power consumption by 45% over legacy DDR and 15% over legacy DDR2. |

Not only does DDR3 continues the evolution of the DDR and DDR2 technologies to provide continued improvements in power reduction but also leads the way for higher performance. DDR3 offers increased transfer rates of PC3-6400 (2.5 ns clock), PC3-8500 (1.875 ns clock), PC3-10600 (1.5 ns. Clock), and PC3-12800 (1.25 ns clock).
Four standard operating frequencies for the DDR3 SDRAM Memory Module specification were developed to provide the use with the most suitable option: PC3-6400, PC3-8500, PC3-10600, and PC2-12800.
PC3-6400 memory module configurations utilize DDR3-800 components to achieve the highest performance, with a peak bandwidth of 6.4GB/s when used in systems operating on 400MHz memory clock frequency.
PC3-8500 memory module configurations utilize DDR3-1066 components to achieve the highest performance, with a peak bandwidth of 8.5GB/s when used in systems operating on 533 memory clock frequency.
PC3-10600 memory module configurations utilize DDR3-1333 components to achieve the highest performance, with a peak bandwidth of 10.6GB/s when used in systems operating on 667 memory clock frequency.
PC3-12800 memory module configurations utilize DDR3-1600 components to achieve the highest performance, with a peak bandwidth of 12.8GB/s when used in systems operating on 800MHz memory clock frequency.
With the continual increase in performance, DDR3 technology is a great new outlook for system designs that are performance driven but with the energy cost savings with 1.5V.
See chart below for a direct comparison between DDR2 vs. DDR3 in both performance and power consumption.
