HP 8GB DDR3 1600MHz ECC Registered Single Rank x4 Low Voltage Refubished

High quality memory module reduced sampling and identification systems for performance, multi-processor servers and computer support Registered ECC technology. 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.
Registered memory are equipped with a controller That controls access to individual memory modules and facilitates the work and memory controller on the motherboard or processor. Memory outwardly behaves as a single module - register the chip - which is responsible for writing and reading 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. Some server boards require registered memory.
Memory has a separately addressable area (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 remained free memory slots.
Memory Module s 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.
