Fujitsu 4GB DDR3 1600 MHz ECC Unbuffered Dual rank x8

Powerful and reliable server memory modules DDR3 with a capacity of 4 gigabytes It is designed for high-performance systems, servers and multiprocessor computers. This memory is primarily intended primarily to powerful servers Fujitsu Primergy TX100 S3P, S1P TX140 and RX100 S7p. It is tested for the most demanding applications, and is ideal for mission-critical corporate applications and critical servers.
Technology ECC checked 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 ECC memory 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.
Memories have two separately addressable area (Memory rank) with bus width 72 bits (64 bits of data and 8-bit ECC code). 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 some 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 or Intel Single Device DataCorrection (SDDC), so they are ideal for the "entry-level" servers.
