HP 4 GB DDR3 1333MHz ECC Registered Single Rank x4 refubished

High-quality memory module with reduced sampling and determining for-performance systems, servers and multiprocessor computers with support for ECC Registered technologies. ECC technology monitors transparently and in real time the integrity of data stored in memory. It is able to find and fix a bug in one bit and detect the error in two bits. Some memory controllers are able in cooperation with ECC memory to repair the mistakes of greater scope. Most server boards require memory with ECC support.

Registered memory are equipped with a controller that controls access to individual memory modules and thus facilitates the work of the memory controller on the motherboard or processor. Memory outwardly behaves as a single module - chip index - which takes care of the writing and reading of individual memory cells and the controller transmits to the outcome of these operations. This increases the efficiency of memory access and processing speed, even when using more memory modules simultaneously. Some server boards require registered memory.

Memory has one individually addressable area (rank memory). Most server chipsets have limited the number of memory rank or directly specified memory configuration for each slot, so you need when buying a watch that figure with respect to future upgrades - when you reach the full rank of memory on the motherboard, you can not add another module, even if remained free memory slots.

Memory module with organizations chips "x4" are designed for the most demanding applications, supporting a wide range of professional technologies such as multiple-bit error correction, Chipkill, memory scrubbing or Intel Single Device DataCorrection (SDDC), making them ideal for critical applications and critical servers.
