128GB DDR4 ECC RDIMM kit for MSI WRX80

This 128GB kit provides two 64GB DDR4 3200 registered DIMMs with ECC and a CAS latency of 22. It is built for the MSI WS WRX80 motherboard and operates at 1.2V. The modules use major OEM chips from Samsung, Micron or Hynix and carry part number MR25600-924K2.

Sustained load stability with registered ECC

Registered buffering reduces electrical load on the memory controller during continuous operation. ECC detects and corrects single-bit errors to maintain data integrity under prolonged workloads. The CL22 timing at 3200 MT/s delivers consistent throughput for server and workstation tasks. Stress testing under load is performed before shipment.

DDR4 288-pin RDIMM interface limits

The 288-pin DDR4 RDIMM form factor fits only DDR4 registered DIMM slots. Maximum speed is PC4-25600 (3200 MT/s) at 1.2V with 2Rx4 organisation. Systems must support registered ECC modules and the WRX80 platform to use this capacity. Mixing with unbuffered or non-ECC DIMMs is not supported.

Questions about this item

How much heat does the 1.2 V DDR4 3200 kit generate under continuous load?

The modules run at 1.2 V with no heat spreader, so they rely on case airflow; typical RDIMM power draw at this voltage stays modest even at full throughput.

What must the system provide for these 288-pin registered ECC modules to function?

A motherboard with DDR4 RDIMM slots that supports ECC and registered memory, such as the MSI WRX80 platform this kit is validated for.

Will the 2Rx4 organisation work alongside older single-rank DDR4 DIMMs I keep installed?

Mixing 2Rx4 registered modules with single-rank DIMMs is not recommended; the memory controller treats each rank differently and can reduce stability or speed.
