HP 16GB DDR4 2133 ECC Unbuffered DIMM

This 16GB DDR4 module runs at 2133 MT/s with CL15 timing and 1.20V operation. It provides ECC error correction in an unbuffered design for data integrity in entry-level server workloads. The dual-rank 2Rx8 organisation fits 288-pin slots in HPE ProLiant Gen9 ML and DL 10/100 families.

Thermals and Power at DDR4 2133

Operating at 1.20V keeps power draw low and heat output modest without a heat spreader. Standard server airflow handles the thermal load quietly at the rated 2133 MT/s speed. The unbuffered topology avoids registered-buffer overhead, helping efficiency in normal use.

Build Fit: 288-Pin DDR4 Slots

The single 16GB DIMM occupies one 288-pin DDR4 slot and requires no extra cooling hardware. It frees remaining slots for future capacity increases up to the platform limit. Builders needing registered memory or higher speeds must choose a different module.

Preguntas sobre este artículo

How do I install the 288-pin DDR4 DIMM and which slot order do people often get wrong?

Align the notch on the 288-pin DDR4 module with the slot key, press straight down until the latches click, and populate the lowest-numbered channel slots first — many builders skip the channel sequence and lose dual-rank performance.

What maintenance or replacement will the 16GB ECC unbuffered kit need over its service life?

No scheduled maintenance is required; if a correctable error count rises or a DIMM fails POST, replace the affected 16GB stick — the module has no heat spreader or moving parts to service.

What limit appears first when the 2133 MT/s CL15 memory runs under sustained load?

The JEDEC 1.20 V voltage ceiling is reached before thermal throttling, so sustained write-heavy workloads hit the voltage guard band first.
