Workstation DDR5 Registered ECC Kit

This V-color OC R-DIMM kit provides 128GB of DDR5 memory in four 32GB modules. It is built for W790 workstation motherboards and uses registered ECC technology for data integrity. The modules run at 5600MHz with CL36 timings and 1.25V operation. This memory is not compatible with standard desktop PCs or laptops.

DDR5 RDIMM Platform Limits

Registered ECC DDR5 modules require a workstation chipset that supports the registered command protocol and error correction. Consumer desktop platforms lack the necessary memory controller features and will not boot with these DIMMs. The 288-pin form factor fits only DDR5 RDIMM slots on qualified W790 boards. Operating temperature is rated from 0 to 85°C.

1Rx4 Rank Configuration Decides Fit

Each 32GB module uses a single-rank 1Rx4 organisation with SK Hynix ICs in a 4Gx4 configuration. This rank structure determines how the memory controller addresses the array and must match the motherboard’s qualified vendor list. Builders needing dual-rank modules or a different IC layout should choose another kit. The kit includes Intel XMP profiles for supported overclocking.

Questions about this item

Should I pick the 128GB kit or look for a smaller capacity for my W790 workstation?

This kit provides 128GB total across four 32GB modules, filling four DIMM slots on a W790 board. Choose it when your workload needs that much registered ECC memory; otherwise a smaller kit leaves slots open for future expansion.

What does the DDR5 5600 CL36 rating actually deliver once installed in a W790 system?

The modules run at 5600 MT/s with timings of 36-38-38-80 at 1.25V, giving registered ECC throughput of PC5-44800. Actual bandwidth depends on the motherboard's memory controller and populated slot count.

How does the 288-pin DDR5 RDIMM interface limit performance on a W790 platform?

The 288-pin registered DDR5 form factor is keyed for W790 workstation boards only; it will not fit desktop or laptop slots. The registered buffer adds one cycle of latency but enables the 128GB quad-rank configuration the platform supports.
