Server Memory Upgrade
This HPE P00922-B21 module adds 16GB of DDR4 capacity to compatible Gen10 Intel servers. It operates at 2933 MHz with a registered signal design for stable operation in multi-module configurations. The single DIMM uses a 288-pin form factor and runs at 1.20 V.
Sustained Workload Behaviour
Registered buffering reduces electrical load on the memory controller, helping maintain data integrity during continuous server tasks. CL21 timing with 21-21-21 cycles delivers consistent latency across extended periods. The 2Rx8 organisation supports efficient bandwidth utilisation under heavy multi-threaded demand.
Registered DDR4 Requirement
This module requires a platform that accepts registered DDR4 DIMMs and cannot be used in systems limited to unbuffered memory. Buyers whose servers need unbuffered modules or a different DDR generation must select an alternative part. Compatibility is validated for HPE Gen10 Intel Servers.

Questions about this item
How much power does each 16 GB DDR4 2933 registered DIMM draw at its rated 1.20 V when the server runs continuously?
Each module operates at 1.20 V; registered DDR4 DIMMs of this capacity typically draw only a few watts under load, so total power impact stays low even with multiple sticks installed.
What motherboard slot and memory-channel configuration must my HPE Gen10 server provide for this 288-pin RDIMM to function?
The module requires a standard 288-pin DDR4 DIMM slot and works in any channel population allowed by the server's memory-subsystem rules for registered memory.
Will the 2933 MT/s CL21 registered module down-clock automatically if I keep slower DDR4 RDIMMs in the same HPE Gen10 server?
Yes, the memory controller will negotiate a common speed and latency supported by all installed registered modules, so faster sticks run at the lower rate.
