Targeted DDR4 ECC RDIMM kit

This 256GB kit contains two 128GB registered DIMMs built for the MSI WS WRX80 platform. ECC and registered buffering protect data integrity in workloads that cannot tolerate silent corruption.

288-pin registered modules without spreaders

Each stick runs at 1.20V with CL22 latency and a 4Rx4 organisation. The bare PCB design fits dense server sockets where tall heat spreaders would block adjacent slots or airflow.

DDR4 3200 ceiling limits bandwidth scaling

The PC4-25600 interface caps transfer rates at 3200 MT/s, so adding further modules will not raise peak throughput beyond this ceiling. Builders needing higher memory bandwidth must choose a platform that supports faster DDR4 or DDR5 standards.

Questions about this item

Does the DDR4-3200 interface cap the kit at PC4-25600 speeds?

Yes, the DDR4 3200 rating sets the maximum transfer rate at PC4-25600 for both 128 GB modules.

What physical slot and pin count do these 288-pin RDIMMs require?

They need a standard 288-pin DDR4 RDIMM slot on the MSI WS WRX80 motherboard.

How are the two 128 GB sticks installed, and which step is often missed?

Insert both modules into the correct channels per the board manual, then verify the BIOS detects the full 256 GB at 3200 MT/s.
