HP 8GB DDR3 1600MHz ECC Unbuffered Dual Rank x8 Low Voltage

High-quality memory module with reduced sampling and determining for-performance systems, servers and multiprocessor computers with support for ECC Unbuffered technology. ECC technology monitors transparently and in real time the integrity of data stored in memory. It is able to find and fix a bug in one bit and detect the error in two bits. Some memory controllers are able in cooperation with ECC memory to repair the mistakes of greater scope. Most server boards require memory with ECC support.

Memory has two separately addressable areas (rank memory). Most server chipsets have limited the number of memory rank or directly specified memory configuration for each slot, so you need when buying a watch that figure with respect to future upgrades - when you reach the full rank of memory on the motherboard, you can not add another module, even if remained free memory slots.

Memory modules with organizations chips "x8" are more affordable, but do not support advanced server technologies such as multiple-bit error correction, Chipkill, memory scrubbing or Intel Single Device DataCorrection (SDDC), making them ideal for "entry-level" servers.
