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.
This Industry Standard 4GB DDR2-800MHz Dual Rank Unbuffered 1.8V 240-pin CL5 UDIMM is 100% guaranteed to be compatible with your system and to work right the first time. Adding additional memory is the best way to increase the performance of your system. All our memory is built to strict JEDEC standards to meet or exceed the Tier 1 OEM's factory requirements. Our products are also guaranteed by federal law to not affect or void OEM warranties.
