Crucial 8 GB DDR4 2133MHz CL15 ECC Registered

Memory Module the latest generation DDR4 and determining for performance systems, servers and multiprocessor computers. DDR4 has a higher frequency and lower energy consumption, and thus reduce thermal radiation. Technology ECC checked transparently and in real time integrity of data stored in memory. It is able to find and fix 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 boards require memory with ECC support.

Registered memory are equipped with a controller That controls access to individual memory modules and facilitates the work of the 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 using more memory modules simultaneously. Some server boards require registered memory.

Memory has two separately addressable areas (Memory rank). The majority of server chipsets has limited memory rank or directly specified memory configuration for each slot, so you must follow when buying this 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 Modules s organizations chips "x8" are affordable, but do not support advanced server technologies such as multiple-bit error correction, Chipkill, memory scrubbing and Intel Single Device DataCorrection (SDDC), so they are ideal for "entry-level" servers.
