Crucial 4GB DDR3 1333MHz CL9 ECC Registered

Peak memory type DDR3 module designed for high-performance work systems, servers and multiprocessor computers.Technology supports ECC Registered with Parity check, and has a capacity of 4 gigabytesThe module is made for an operating frequency of 1333 MHz, at which reaches CL9 timings.Nominal supply voltage is 1.5 V.Crucial memory are highly reliable and fully compatible with many manufacturers of motherboards.

ECC technology transparently monitors in real time the integrity of the data stored in memory.It is able to find and correct the error in a single bit error and detect two bits.Some memory controllers can in cooperation with ECC memory and correct errors of greater magnitude.Most server boards require memory with ECC support.In cooperation with the parity check memory achieves maximum control of data transferred.Parity is that the word was added jednobytovému auxiliary information (calledparity bit) and because it can then verify the authenticity of data transmitted.

Registered memory is equipped with its own controller, which controls access to individual memory modules and facilitates the work and memory controller on the motherboard or the processor.Memory outwardly behaves as a single module - register the chip - which is responsible for writing and reading from the individual memory cells and controller transmits to the outcome of these operations.This increases the efficiency of memory access and processing speed even when using multiple memory modules simultaneously.Some server boards require registered memory.

Memory has two separately addressable areas (memory rank) with a bus width of 72 bits (64 bits of data and 8 bits of ECC code).Most server chipsets has limited the number of memory rank or directly prescribed for each configuration memory slots, so you need to watch this when purchasing data with respect to future upgrades - if you reach the full rank of memory on the motherboard, you can not add another module even if it remained an open memory slots and reserve capacity.
