Crucial 16GB DDR4 2133MHz CL15 ECC Registered

The premium DDR4 memory kit comes with higher speeds, more throughput, more bandwidth, and higher efficiency. The memory is designed for powerful systems, servers, and multiprocessor computers with ECC Registered technology, which checks transparently and in real time the integrity of data stored in memory. It can find and fix an error in one bit and detect the error in two bits. Some memory controllers can also repair larger-scale errors in conjunction with ECC memory. Most server boards require memory with ECC support.

Registered memory is equipped with a proprietary controller that controls access to individual memory modules, making it easier for the memory controller to work on the board or processor. The memory behaves externally as the only module - the register chip - which takes care of writing and reading from individual memory cells and transfers the controller to the result of these operations. This increases the efficiency of memory access and processing speed even when multiple memory modules are used at the same time. Some server boards require registered memory.

The memory has two individually addressable areas (memory rank). Most server chipsets have a limited memory rank or a specified memory configuration for individual slots, so you need to track this data for future upgrades - if you have full memory rank on the motherboard, you will not be able to add another module even if there are free memory Slots.

The "x4" chip-based memory modules are designed for the most demanding applications, supporting a variety 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.
