Kingston 8GB DDR3 1600MHz CL11 ECC Registered Single Rank

A fast and reliable DDR3 memory module for powerful systems, servers and multiprocessor computers to boost multitasking performance and demanding applications. Supports ECC Registered technology required by professional systems. Kingston memory is recommended by motherboard and computer manufacturers for perfect compatibility and reliability.
ECC technology 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 the ECC. Most server boards require memory with ECC support. In cooperation with parity control, the memory achieves maximum control of transmitted data.
Registered memory is equipped with a custom controller that controls access to individual memory modules to make 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 result of these operations to the controller. 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 a single memory address with a bus width of 72 bits (64 bit data and 8 bit ECC code). Most server chipsets have a limited memory rank or a specified memory configuration for individual slots, so you need to track this figure 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 some free Memory slots.
The "x4" chip 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.
