DRL800FB2/8GB - Dataram 8GB Kit (2 X 4GB) DDR2-800MHz PC2-6400 ECC Fully Buffered CL6 240-Pin DIMM Dual Rank Memory

Each DRL800FB2 upgrade consists of a matched set of two DDR2-800 FB-DIMMs. One Advanced Memory Buffer (AMB) is used as the interface between the system memory bus and DIMM DRAMs. One 2K-bit EEPROM is used for Serial Presence Detect. For improved thermal performance, a Full DIMM Heat Spreader with thermal interface material (TIM) is attached to the front and back of the DIMM.
