AddOn Networks 4GB DDR2 memory module 1 x 4 GB 667 MHz ECC

Double Data Rate 2(DDR2) SDRAM memory is a product built upon the foundation of older DDR memory technology. DDR2 SDRAM memory can do two operations per clock cycle, just like DDR memory with speeds upto 800Mhz. By having DDR2 technology, you are increasing your memory bandwidth over the corresponding DDR SDRAM.

DDR2 is the evolution of DDR memory technology. DDR2 memory features lower power consumption, higher data bandwidths, faster speeds and enhanced thermal performance.

- Speeds: PC3200, PC4200, PC5300
- Capacities: 128MB to 4GB
- Available in 240 pin DIMMs and 200 pin SO-DIMMs
- ECC or non-ECC, Unbuffered and Registered DDR2 Modules
