HP Gen9 Server Memory Kit

This 16 GB kit contains two 8 GB DDR4 registered DIMMs built for HP ProLiant DL380p Gen9, DL560 Gen9 and ML350 Gen9 servers. It targets administrators who need ECC protection and registered signalling for stable operation in multi-socket platforms.

Registered ECC Build With Standard Pinout

Each module uses a 288-pin DDR4 interface without a heat spreader, relying on server chassis airflow for cooling. Registered buffering and ECC reduce electrical load on the memory controller and correct single-bit errors during continuous workloads.

DDR4-2133 Speed And Platform Limits

The kit runs at 2133 MHz with CL15 timing at 1.2 V, matching the CPU memory-controller specification for these Gen9 systems. Maximum supported capacity reaches 1.50 TB using registered DIMMs across 48 sockets when four processors are installed.
