HP 500207-071 16GB DDR3-1066 ECC Registered DIMM (RDIMM) — SAMSUNG M393BNK70CM0-CF8Q5T: This is a 16GB DDR3-1066 (PC3-8500R) Quad Rank x4 ECC Registered server memory module. The HP 500207-071 part number is HP's spare/option SKU for the SAMSUNG M393BNK70CM0-CF8Q5T DRAM module — they are the same physical part. This is a 240-pin Registered DIMM, not an unbuffered (UDIMM), Load-Reduced (LRDIMM), or SODIMM module. This is a refurbished unit, tested before shipment.
Engineering Context
The 500207-071 is HP's high-density 16GB DDR3-1066 RDIMM for ProLiant G6 / G7 servers and was the standard option for maxing out memory in the early-DDR3 generation. As a Quad Rank x4 module it provides 16GB per slot but typically forces the host channel to run at 800 MT/s when more than two QR DIMMs share a channel — this is a property of DDR3 QR memory controllers, not a defect. The module runs at 1.5V (standard DDR3). CAS Latency on PC3-8500R-7 is 7-7-7. ECC and Registered/Buffered features are required by ProLiant memory controllers in this generation.
Deployment & Use Cases
High-capacity memory expansion for HP ProLiant G6/G7 servers (DL360 G6/G7, DL380 G6/G7, DL580 G7, BL460c G6/G7, ML370 G6) where 16GB-per-slot density is required. Database and virtualization hosts running on G6/G7 hardware. Lab and homelab consolidation builds. Validated third-party servers that accept PC3-8500R 1.5V Quad Rank RDIMMs (consult vendor QuickSpecs / memory population rules).

Compatibility & Hard Constraints
Designed for HP ProLiant G6/G7 servers and validated PC3-8500R 1.5V platforms. Will not function in DDR2, DDR4, or DDR5 sockets. Will not function in UDIMM-only, LRDIMM-only, or SODIMM sockets. Will not function in servers that require Low-Voltage (1.35V, PC3L) memory unless the BIOS supports mixed-voltage. As a Quad Rank module, populating more than two per channel will force the channel to 800 MT/s — consult HP QuickSpecs and memory population rules for the target server. Mixing ranks/widths on the same channel may force the channel to the lowest common configuration.
