Samsung 16GB DDR3 Registered ECC PC3-8500 1066Mhz Memory Module

The Samsung M393B2K70CM0-YF8 is a 16 GB DDR3 Registered ECC memory module built for servers that cannot afford downtime or data errors. Running at 1066 MHz, it delivers the steady bandwidth that database hosts, virtualization clusters, and file servers need to keep multiple users productive.

This module uses a four-rank by four-bit configuration that balances density and signal integrity. A built-in register reshapes clock, command, and control signals before they reach each DRAM chip, so motherboards can maintain timing accuracy even when every slot is populated. The eight-bit error-correcting code identifies and repairs single-bit faults on the fly, preventing many crashes and silent data corruptions that standard memory would miss.

Flexible voltage support at 1.5 V or 1.35 V lets the DIMM run in legacy systems as well as newer energy-conscious platforms, helping data centers trim power without sacrificing reliability. The 240-pin RDIMM format fits any motherboard that accepts PC3-8500 Registered memory, making upgrades straightforward for IT teams looking to expand capacity in aging rack servers or scale out newer blade environments.

Whether you are consolidating virtual machines, crunching large data sets, or simply keeping critical business applications online around the clock, this Samsung module offers the consistency and peace of mind expected from server-class hardware.
