16GB DDR4 ECC Registered Module

This 16GB DDR4 2133 module uses a 288-pin form factor with ECC and registered buffering. It operates at 1.20V with a CAS latency of CL15 and a 2Rx4 rank configuration. The memory is designed for server platforms that require registered DIMMs with error-correction capability.

Compatibility Check Before Ordering

Verify that your server motherboard accepts 288-pin DDR4 registered DIMMs with ECC support. Systems built for unbuffered consumer memory will not recognise this module. Confirm the maximum supported capacity per slot and the qualified voltage list in your platform documentation before purchase.

Thermals Noise and Power Draw

Standard DDR4 registered modules run passively without dedicated fans and produce no audible noise. Power draw scales with the 1.20V operating voltage and the 2133 MT/s data rate under typical server workloads. Ensure your chassis airflow covers the memory slots to maintain stable temperatures during sustained operation.

Spørgsmål om denne vare

Does the module ship alone or in a kit with multiple sticks?

This listing is for a single 16GB DDR4 2133 registered ECC module; additional sticks must be purchased separately.

Is the 2Rx4 dual-rank layout better than a single-rank alternative for my server?

Dual-rank 2Rx4 modules increase memory density per slot, which helps reach higher total capacities on boards with limited DIMM slots.

Will the PC4-17000 rating deliver its full 2133 MT/s speed in my system?

The module runs at 2133 MT/s when the platform supports that speed; otherwise it downclocks to the highest speed the memory controller allows.
