SAMSUNG M393B2G70QH0-YH9 16GB DDR3-1333 ECC Registered DIMM: This is a 16GB DDR3 server-class registered DIMM (RDIMM) with ECC, rated at DDR3-1333 (PC3-10600), in a 240-pin form factor. The module is a Samsung-manufactured server memory part. This is a buffered registered DIMM intended for server motherboards that explicitly support RDIMM; it is not a desktop UDIMM and is not a laptop SODIMM. This is a refurbished unit.
Engineering Context
Registered DIMMs include a register chip that buffers address and command signals between the memory controller and the DRAM chips, which reduces controller electrical load when multiple modules are populated per channel. This is what allows server platforms to populate larger DIMM counts per channel than unbuffered DIMM platforms. ECC adds a parity bit lane on the 72-bit data path so the controller can correct single-bit errors and detect multi-bit errors at run time. The DDR3-1333 speed grade corresponds to a 1333 MT/s data rate (PC3-10600 module rating). The 240-pin DDR3 keying is mechanically incompatible with DDR2 (different notch position) and DDR4 (288-pin) sockets.
Deployment & Use Cases
Server memory upgrades for DDR3-generation platforms that accept 16GB DDR3-1333 RDIMMs, restorations of existing DDR3 ECC RDIMM-based hosts, and replacement units for failed modules in virtualization hosts, database servers, file servers, and Hadoop or storage cluster nodes where the platform's qualified-memory list calls for a 16GB DDR3-1333 registered DIMM.

Compatibility & Hard Constraints
Compatible with server motherboards that accept 240-pin DDR3-1333 ECC registered DIMMs of 16GB capacity per slot. Not compatible with DDR2 or DDR4 motherboards (different keying and pin counts). Not compatible with desktop motherboards that require unbuffered DIMMs (UDIMM); registered modules will not POST on UDIMM-only platforms. Not compatible with laptops or any system using SODIMM. Some servers enforce vendor-branded memory through firmware checks; verify your platform's qualified-vendor list and that your memory controller supports 16GB DDR3-1333 RDIMMs before purchase.
