KINGSTON 4GB Quad KIT DDR2 667 MHz ECC Fully Buffered

Convenient kit of four server memory modules of DDR2 Fully Buffered DIMM with a total capacity of 4 gigabytesIt is designed for modern high-performance systems, servers and multiprocessor computers.It comes in a separate box packing.Kingston are recommended manufacturers of motherboards and computers for its perfect compatibility and reliability.Luxury of a lifetime warranty!
Fully Buffered memory modules are working as registered memory, however, are based on a fast 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 the processor.Individual memory you are using this circuit serially connected to an external memory controller and possibly gradually to other modules.Memory outwardly behaves as a single chip, which handles reading and writing of individual memory cells and controller transmits to the outcome of these operations.This increases the efficiency of memory access and processing speed even when using multiple memory modules simultaneously.In addition, significantly simplifies the design of the memory controller on board, drastically reducing the number of pins on the DIMM module and can be fitted easily considerably more memory.Some server boards require Fully Buffered memory.
ECC technology transparently monitors in real time the integrity of the data stored in memory.It is able to find and correct the error in a single bit error and detect two bits.Some memory controllers can in cooperation with ECC memory and correct errors of greater magnitude.Most server boards require memory with ECC support.
Memory has a separately addressable area (memory rank).Most server chipsets has limited the number of memory rank or directly prescribed for each configuration memory slots, so you need to watch this when purchasing data with respect to future upgrades - if you reach the full rank of memory on the motherboard, you can not add another module even if it remained an open memory slots.
Memory modules with organizations chips "x8" are affordable, but do not support advanced server technologies like multiple-bit error correction,
Chipkill, memory scrubbing or Intel Single Device DataCorrection (SDDC), so they are ideal for "entry-level" servers.
