HP 16GB DDR4 Registered Server Memory

This module delivers 16GB of DDR4 capacity at 2133 MT/s with CL15 timing and 1.20V operation. It uses a 288-pin registered dual-rank x4 design built for HP ProLiant Gen9 servers.

HP SmartMemory Qualification

The SmartMemory feature enables the server to verify that each module has passed HP qualification and testing. When managed through HP OneView, it also activates fault prediction capabilities for the memory subsystem.

DDR4 2133 Registered Platform Limit

Registered DDR4 2133 memory is bound by the JEDEC PC4-17000 standard and the server memory controller's supported speeds. Systems that require higher data rates or unbuffered modules cannot use this kit.

Questions about this item

Will the registered DDR4 2133 modules need any firmware updates or recalibration over time?

No firmware updates or recalibration are required; the registered DDR4 2133 modules operate at 1.20 V with CL15 timing for their service life.

What is the first limit reached when the 16 GB kit runs at full DDR4 2133 speed continuously?

The DDR4 2133 (PC4 17000) data rate and CL15 latency are the fixed operating limits; the registered buffer maintains signal integrity at that speed.

How much heat and power does the 288-pin registered kit produce during all-day operation?

Each 16 GB module runs at 1.20 V with CL15 15-15-15 timing, so power draw and heat stay at standard DDR4 2133 registered levels.
