NANYA NT8GC72C4NG0NK-CG 8GB DDR3-1333 ECC Registered DIMM (HP 647650-071 equivalent): This is an 8GB DDR3 server-class registered DIMM (RDIMM) with ECC, rated at DDR3-1333 (PC3-10600), in a 240-pin form factor. The module is a Nanya-manufactured part cross-referenced as HP P/N 647650-071. This is a buffered registered DIMM intended for HP ProLiant servers and equivalent registered-memory platforms; 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. 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
HP ProLiant servers that specify HP part 647650-071 on their qualified-vendor memory list, restorations of existing DDR3-1333 ECC RDIMM-based hosts, and replacement units for failed modules in virtualization hosts, database servers, file servers, and Hadoop or storage cluster nodes where matching the original HP-listed 8GB DDR3-1333 RDIMM specification is required.

Compatibility & Hard Constraints
Compatible with HP server platforms that list HP P/N 647650-071 on their qualified-vendor memory list and with motherboards that accept generic 240-pin DDR3-1333 ECC registered DIMMs. 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 HP servers enforce HP-branded SmartMemory through firmware checks; verify the qualified-vendor list for your specific server before purchase.
