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 684316-181 — the Gen8 v2 (Ivy Bridge / E5-2600 v2) SmartMemory PN. Samsung MPN M393B2G70DB0-CK0 (DB die revision), spec 16GB 2Rx4 PC3-12800R-11-12-E2, 1.5V standard voltage. All four sticks are made in Philippines.

Why HP 684316-181 specifically matters: HP ProLiant Gen8 v2 servers (DL360p / DL380p / DL160 / ML350p Gen8 v2 — all E5-2600 v2 Ivy Bridge-based) log a "Not authenticated" AMS warning if the memory PN doesn't match the CPU generation. 684316-181 is the correct SmartMemory PN for these v2 servers.

Condition & testing: Pulled from decommissioned HPE Gen8 v2 servers with HP Security ID sticker intact. Visually inspected. Sold as functional warranty pulls; see return policy.

What's included: 4 × Samsung 16GB DDR3-1600 ECC RDIMM (HP 684316-181, SmartMemory, M393B2G70DB0-CK0).
