Kingston KIT 8 GB of DDR2 667MHz ECC Fully Buffered CL5 DIMM Dual Rank x4

A preferred kit two server memory module of type DDR2 Fully Buffered DIMM with a total capacity of 8 gigabytes It is designed for advanced performance systems, servers and multiprocessor computers. It comes in a separate box packaging. Kingston memory are recommended by the manufacturer of motherboards and computers for its perfect compatibility and reliability. Luxury is a lifetime warranty!
Fully Buffered memory modules operate similarly to registered memory, however, are based on speed serial architecture. The module is a separate circuit AMB - Advanced Memory Buffer that controls access to individual memory modules and facilitates the work and memory controller on the motherboard or processor. Individual memory modules are over this circuit connected in series to an external memory controller and possibly gradually to other modules. Memory outwardly behaves as a single chip, which handles the reading and writing of individual memory cells, and control passes to the outcome of these operations. This increases the efficiency of memory access and the processing speed even when more memory modules simultaneously. Moreover, it considerably simplifies the construction of the memory controller on the board dramatically reduce the number of pins on the DIMM module can easily be fitted with a substantially larger amount of memory. Some server boards require Fully Buffered memory.
Technology ECC checks transparently and in real time integrity of data stored in memory. It is able to detect and correct an error in a single bit error and detect two bits. Some memory controllers can in cooperation with ECC memory repair the errors of greater magnitude. Most server board requires ECC memory support.
Memory has two separately addressable areas (memory rank). Most of server chipsets has limited memory rank or directly specified memory configuration for each slot, so consider when buying a watch that figure with respect to future upgrades - if you reach the full rank of memory on the motherboard, you can not add another module even if some remained free memory slots.
Memory modules with organizations chips "x4" are designed for the most demanding applications, supporting a broad range of professional technologies such as multiple-bit error correction, Chipkill, memory scrubbing or Intel Single Device DataCorrection (SDDC), so they are ideal for mission-critical and mission-critical servers.
