Workstation DDR5 R-DIMM kit

This kit provides 128 GB of registered ECC DDR5 memory across four 32 GB modules. It is built for AMD TRX50 workstation platforms that require registered DIMMs with on-die error correction and AMD EXPO overclocking profiles.

Registered design with thermal sensor

Each module uses a 288-pin RDIMM form factor with a heat spreader and a 10-layer PCB. The registered buffer reduces electrical load on the memory controller, while an on-board temperature sensor monitors thermals to protect data integrity during sustained workloads.

DDR5 bandwidth and platform limits

DDR5 doubles the sub-channel count versus DDR4, delivering two 40-bit channels per DIMM for higher throughput at 5600 MT/s. The registered ECC design and 1.25 V operation are intended for TRX50 workstation motherboards only; the modules will not function in standard desktop or laptop systems.

Highlights

  • DDR5 5600 speed with CL36 latency
  • Registered ECC with on-die error correction for data integrity
  • AMD EXPO profile enables one-click overclocking on TRX50
  • Hynix ICs on 10-layer PCB with thermal sensor

Questions about this item

What DDR5 speed and latency does the AMD EXPO profile on this TRA532G56S436Q kit set?

The AMD EXPO profile on this TRA532G56S436Q kit sets DDR5 5600 speed with CL36-38-38-80 timings at 1.25V.

What motherboard slot and physical clearance does this 288-pin DDR5 RDIMM kit require?

Each 32GB module uses a standard 288-pin DDR5 RDIMM form factor with a heat spreader; four DIMM slots and enough height clearance for the spreader are required.

How do I enable the rated 5600MHz speed on a TRX50 workstation, and what step is often missed?

Install all four modules in the correct TRX50 channel slots, enter the BIOS, enable the AMD EXPO profile, save and reboot; the step often missed is enabling EXPO after seating the modules.
