HPE 8GB (1x8GB) Single Rank x8 DDR4-2666 Smart Memory Kit (815097-B21 / 840755-091)

The HPE 8GB Single Rank x8 DDR4-2666 Registered Memory Kit (HPE Option Part Number: 815097-B21 / Assembly Part Number: 840755-091 / Spare Part Number: 850878-001) is an original server-grade DRAM module engineered for 10th Generation HPE ProLiant servers and Synergy compute modules. Operating at 2666 MT/s with a low CAS latency of CL19 at standard 1.2V, this Single Rank x8 (1Rx8) Registered DIMM (RDIMM) provides reliable base-level memory expansion for entry-level and mid-range server workloads.

Equipped with Error-Correcting Code (ECC) technology and HPE SmartMemory architecture, the 815097-B21 module actively detects and corrects single-bit memory errors to prevent system crashes and data corruption. Integrated SmartMemory signal optimization enables HPE ProLiant Gen10 servers to verify genuine DRAM authentication through Active Health System (AHS) logging, unlocking enhanced memory tuning, extended RAS features, and consistent signal integrity under daily operational loads.

Available from DataDive, your trusted Server Parts Supplier in Doha, this original HPE server RAM module is available in our Memory collection, ideal for expanding server redundancy, replacing faulty memory modules, reducing energy costs, and powering enterprise infrastructure across supported HPE ProLiant rack and tower server platforms.
