Kingston's KVR800D2D8F5K2/4G is a kit of two 2GB (256M x 72-bit) PC2-6400 CL5 SDRAM "fully buffered" ECC "dual rank" memory modules. Total kit capacity is 4GB (4096MB). Each module is based on eighteen 128M x 8-bit 667MHz DDR2 FBGA components. Each module also includes an AMB device (Advanced Memory Buffer).

FB-DIMMs represent the next-generation server memory technology that is currently being standardized by JEDEC, the industry's standard group. Intel Corporation is a key developer of FB-DIMM technology and the first adopter, launching it on its two-way Xeon servers (code-named "Bensley") with 5000 series chipsets. FB-DIMMs are "intelligent" memory modules, incorporating a special memory controller built into the memory module.

FB-DIMMs are not compatible with existing servers utilizing DDR2 Registered DIMM memory. They also will not work in desktop or mobile platforms as they are only designed for servers with FB-DIMM memory architecture.
