System-specific DDR4 module

This 32 GB DDR4 2133 registered DIMM is built for HP and Compaq workstations and servers that require ECC memory. The single-module design adds 32 GB of capacity in one 288-pin slot without mixing ranks.

ECC registered reliability

Error-correcting code and registered signal processing protect data integrity in multi-socket systems and reduce electrical load on the memory controller. The 1.20 V operating voltage matches the DDR4 standard for these platforms.

DDR4 2133 bandwidth ceiling

The PC4 17000 rating sets the maximum transfer rate at 2133 MT/s, so throughput is limited to that speed even if the platform supports faster DDR4. Systems locked to lower memory bus speeds will run this module at the lower frequency.

Questions about this item

Does the DDR4 2133 (PC4 17000) interface cap at 1.20V for registered ECC modules?

Yes, this registered ECC DIMM operates at the standard DDR4 1.20V while running at 2133 MHz (PC4 17000).

Will the 288-pin 32GB DIMM fit my HP/Compaq system that requires registered memory?

The module uses the standard 288-pin DDR4 DIMM form factor and is specified for HP/Compaq systems needing registered ECC memory.

Do I need to populate specific slots first when installing this 2Rx4 registered module?

Install the DIMM in the slot designated for channel 0 or CPU 0 per your HP/Compaq service guide; registered modules must follow the platform's population rules.
