Capacity and configuration

This kit delivers 512GB of DDR4 memory across four 128GB modules, built for MSI WRX80 motherboards. The 4Rx4 registered ECC design targets workstations and servers that need maximum density per slot.

Platform integration and slot usage

Registered DIMMs with ECC require a chipset and CPU that support both features, which the WRX80 platform provides. The four-module kit fills four 288-pin slots at 1.2V, leaving any remaining channels open for further expansion.

Workload headroom and limits

CL22 timing at 3200 MT/s handles large datasets, virtualisation and multi-threaded compute where capacity outweighs latency. The 4Rx4 organisation maximises rank density, so bandwidth per core becomes the bottleneck before the memory controller reaches its module limit.

Questions about this item

Will the 3200 MT/s speed hold under sustained load with CL22 latency?

The kit is rated for DDR4 3200 at CL22; sustained throughput will be limited by the 4Rx4 rank density and the motherboard's memory controller capabilities.

What thermal and acoustic impact should I expect from four 128 GB RDIMMs running continuously?

Each module operates at 1.20 V without a heat spreader; total power draw scales with all four sticks active, and fan noise depends entirely on your chassis airflow design.

Which motherboard features must my system already provide for this 512 GB kit to function?

An MSI WRX80 board with 288-pin DDR4 slots supporting registered ECC RDIMMs, 4Rx4 organisation and 1.2 V operation is required.
