Server Memory Upgrade

This A-Tech module provides 16GB of DDR4 ECC registered memory for compatible server and workstation systems. It is designed to increase capacity and improve multitasking performance in enterprise environments. Buyers who need non-ECC unbuffered DIMMs for consumer desktop platforms cannot use this part.

Registered ECC 2Rx4 Configuration

The module operates at DDR4 2133MHz with a CL15 latency and 1.20V voltage using a 2Rx4 rank organisation. Registered buffering and error-correcting code are mandatory for the target platform; systems requiring unregistered or non-ECC memory will not accept this DIMM.

Standard Voltage Thermals

Running at the standard 1.2V DDR4 voltage, the module maintains typical power draw and thermal output for registered server memory. Passive cooling via system airflow is sufficient for normal operation; no active cooling on the DIMM itself is required.

Questions about this item

What does the 2133 MHz speed mean for actual server workloads?

The module runs at 2133 MHz with CL15 latency, delivering PC4-17000 bandwidth that matches the rated throughput of DDR4-2133 registered DIMMs in compatible HP servers.

How does the ECC RDIMM interface affect usable capacity and stability?

As a registered ECC DIMM, it adds a register buffer and error-correcting code, so the memory controller sees one electrical load per module and can correct single-bit errors, improving reliability in multi-DIMM configurations.

Will the 288-pin 2Rx4 form factor fit my HP ProLiant Gen9 slot?

The stick is a standard 288-pin DDR4 RDIMM with a 2Rx4 rank layout and 1.2 V operation, matching the physical and electrical requirements of the listed HP part numbers such as 774172-001 and 817547-081.
