What you're buying: A lot of 4 × 16GB Samsung DDR3-1600 ECC Registered (RDIMM) server memory (64GB total) carrying HP's SmartMemory badge and HP part number 672612-081. Samsung MPN M393B2G70BH0-CK0Q9, spec 16GB 2Rx4 PC3-12800R-11-11-E2, 1.5V standard voltage. All four sticks share the same date code (1316, Q1 2013), all made in Philippines.

Why HP SmartMemory matters: HP ProLiant Gen8 servers log a "Warranty Message: Not authenticated" warning when non-SmartMemory sticks are installed. HP SmartMemory sticks pass HP's authentication check without any log noise.

Note on Q8 vs Q9: Samsung ships this HP 672612-081 SKU in both -CK0Q8 and -CK0Q9 production runs. Both are electrically identical PC3-12800R 2Rx4 modules — same spec, same voltage, same HP validation. Fully interchangeable.

Condition & testing: Pulled from decommissioned HPE Gen8 servers. Visually inspected. Sold as functional warranty pulls; see return policy.

What's included: 4 × Samsung 16GB DDR3-1600 ECC RDIMM (HP 672612-081, SmartMemory, M393B2G70BH0-CK0Q9).
