Target Workstation Memory

This 64GB kit comprises four 16GB DDR5 registered DIMMs validated for AMD TRX50 workstation motherboards. Each module carries an AMD EXPO profile rated at 5600MHz with CL36-38-38-80 timings at 1.25V. On-die ECC and registered signalling protect data integrity in professional workloads.

Thermals and Power Draw

Hynix ICs on a 10-layer PCB distribute heat across the integrated spreader during typical operation. The registered buffer and on-board PMIC regulate voltage locally, keeping power draw predictable at the specified 1.25V. No active cooling is required for standard TRX50 workloads at the profiled frequency.

Sustained Load Behaviour

Under continuous load the EXPO profile maintains 5600MHz with the published CL36 latency without dropping to lower JEDEC speeds. Dual 40-bit sub-channels per DIMM preserve bandwidth efficiency across all four modules. Registered buffering and on-die ECC continue to correct errors throughout extended compute sessions.

Questions about this item

How do I install the 288-pin DDR5 RDIMMs on a TRX50 motherboard and which slot order is the step people get wrong?

Align the key notch on each 288-pin module with the slot, press straight down until both side clips click, and populate the four DIMM slots in the order the TRX50 manual specifies for quad-channel operation — skipping that sequence is the common mistake.

What maintenance or replacement will the on-board PMIC and Hynix ICs need later?

The on-board PMIC and Hynix ICs have no user-serviceable parts; keep the heat spreader clean and ensure case airflow stays unobstructed, and replace the full kit only if ECC logs report uncorrectable errors.

At what point does the CL36 5600MHz timing hit its limit under sustained load?

The CL36 36-38-38-80 timing at 1.25V remains stable until the on-die ECC correction capacity is exceeded or the PMIC thermal threshold is reached, whichever occurs first during prolonged heavy workloads.
