IBM 16GB DDR3 1333MHz ECC Registered Dual Rank x4

High quality memory module of type DDR3 from an experienced manufacturer IBM designed for high-performance systems , Multiprocessor servers and IBM PC brand. Supports Registered ECC technology and parity checking has a 16GB . Technology ECC checks transparently and in real time integrity of data stored in memory. It is able to detect and correct 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 board requires memory with ECC support. In collaboration with parity checking memory reaches maximum control of data transferred. Parity is that the word jednobytovému added auxiliary information (the parity bit) and because it can then verify the authenticity of transmitted data.
Memory has two separately addressable area (Memory rank). Most of server chipsets has limited memory rank or directly specified memory configuration for each slot, so consider when buying a watch that 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.
