Kingston 4GB DDR3 1600MHz ECC Registered Single Rank

A fast and reliable DDR3 memory module designed for powerful systems, servers, and multiprocessor computers to boost multitasking and demanding applications. Supports ECC Registered Technology. Kingston memory is recommended by motherboard and computer manufacturers for their 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 memory. 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 a single 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 a registered memory.

The memory has a single memory address with a bus width of 72 bits (64 bit data and 8 bits 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 "x8" chip memory modules are affordable, but they do not support advanced server technologies such as multiple-bit error correction, Chipkill, memory scrubbing, or Intel Single Device DataCorrection (SDDC), so they are ideal for entry-level servers.
