16 GB quad-channel DDR4 ECC kit

This kit provides 16 GB of DDR4 2133 MHz registered ECC memory across four 4 GB modules. It is built for servers and workstations that require error-correcting registered DIMMs. Desktop and laptop systems cannot use these modules. Verify your platform supports DDR4 ECC RDIMMs before purchase.

Registered ECC with single-rank layout

The registered buffer reduces electrical load on the memory controller, allowing stable operation in multi-module configurations. Single-rank 1Rx8 organisation helps maintain signal integrity at the rated speed. On-die ECC corrects single-bit errors to protect data integrity in critical workloads.

DDR4 2133 MHz CL15 at 1.20 V

The modules run at the standard DDR4 voltage of 1.20 V with a CAS latency of 15 cycles. This speed and timing combination determines whether the kit matches your system's qualified memory list. If your server requires a different data rate or latency, this kit will not be compatible.

Klausimai apie šią prekę

Will the lack of heat spreaders on these 1Rx8 DDR4 modules require additional cooling maintenance?

No maintenance is needed; the modules run at the standard 1.20 V DDR4 voltage and have no heat spreaders, relying on normal chassis airflow.

What limits sustained throughput first — the CL15 latency or the 2133 MT/s bus speed?

The 2133 MT/s bus speed is the primary ceiling; CL15 timing operates within that fixed data rate.

How much power and heat do four registered DIMMs add when the server runs all day?

Each 4 GB stick draws 1.20 V at DDR4 standard levels; total kit power stays low and is handled by typical server airflow.
