How this unit is built
Recovered from end-of-life equipment, inspected and tested before it ships.
See the production flowSAMSUNG M393B5170H0-CH9Q5 4GB DDR3 ECC Registered DIMM, 1.5V (HP 500203-061 equivalent): This is a 4GB DDR3 server-class registered DIMM (RDIMM) with ECC, operating at 1.5V, in a 240-pin form factor. The module is a Samsung-manufactured part cross-referenced as HP P/N 500203-061. 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 1.5V operating voltage is the standard DDR3 nominal level, distinct from DDR3L modules that operate at 1.35V; some servers accept either, while others lock to one voltage. 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 500203-061 on their qualified-vendor memory list, restorations of existing DDR3 ECC RDIMM-based hosts, and replacement units for failed modules in virtualization hosts, database servers, and file servers where matching the original HP-listed 4GB DDR3 RDIMM specification is required.
Technical Specifications
Compatibility & Hard Constraints
Compatible with HP server platforms that list HP P/N 500203-061 on their qualified-vendor memory list and with motherboards that accept generic 240-pin DDR3 ECC registered DIMMs at 1.5V. 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. Not guaranteed to operate on platforms that strictly require DDR3L 1.35V modules. Some HP servers enforce HP-branded SmartMemory through firmware checks; verify the qualified-vendor list for your specific server before purchase.
