HPE 16GB DDR4 Registered DIMM

This 16GB DDR4 module uses a registered design and a 288-pin form factor to deliver stable memory performance. It operates at a low 1.2V voltage for efficient power use in compatible servers. The part number 805349-B21 identifies the specific HPE SmartMemory unit.

Suited for HPE ProLiant Gen9

This memory targets administrators upgrading or repairing supported HPE ProLiant Gen9, Apollo, Synergy or BladeSystem servers. It is not intended for desktop motherboards, consumer laptops or systems that require unbuffered modules. Buyers needing non-registered DIMMs should look elsewhere.

Fits 288-pin DDR4 slots in qualified HPE systems

Installation requires an available 288-pin DDR4 DIMM slot on a validated HPE server board. The registered signal processing helps maintain signal integrity across populated channels. Using HPE-qualified memory enables extended performance features through the system ROM.
