Target System and Module Type

This 16 GB DDR4 ECC RDIMM is built for registered server and workstation platforms that require error-correcting memory. It fits 288-pin DDR4 slots and operates at the standard 1.2 V JEDEC voltage. The module is validated for compatibility with MSI WRX80 motherboards and similar enterprise boards.

Registered ECC and Rank Architecture

The single specification that decides fit is the registered ECC RDIMM design with a 2Rx4 organisation. Buffered addressing and on-die error correction are mandatory for the target chipsets; unbuffered or non-ECC modules will not function in these systems.

Sustained Load Behaviour

Without a heat spreader the module relies on chassis airflow to maintain stability during continuous workloads. All units are stress-tested under load before shipment to verify reliable operation at the rated 3200 MT/s speed and CL22 latency over extended periods.

Questions about this item

What does the 3200 MT/s speed mean once the module is installed in a compatible system?

The module runs at DDR4 3200 (PC4-25600) with CL22 latency, delivering the rated bandwidth when the motherboard and CPU support that speed.

How does the registered ECC design affect what the memory controller can do?

As a registered ECC RDIMM, it places a register between the DRAM and the memory controller, reducing electrical load and enabling error correction for stable server workloads.

What physical slot and keying does this 288-pin RDIMM require?

It fits a standard DDR4 288-pin RDIMM slot with the registered-module key notch; the board must accept registered ECC DIMMs.
