Rank 1Rx8

  • ECC registered design protects data integrity in critical workloads
  • 7200 MHz DDR5 speed accelerates memory-intensive applications
  • CL34 low latency tightens response times for compute tasks
  • AMD EXPO profile enables one-click overclocking on TRX50 platforms
  • Hynix ICs on 10-layer PCB deliver validated stability at 1.40 V

TRX50 Workstation Memory Kit

This 64GB kit contains four 16GB DDR5 RDIMMs rated at 7200MHz with CL34 timings. It targets Threadripper PRO 7000 series workstations that require registered ECC memory with AMD EXPO overclocking profiles.

Platform and Voltage Requirements

Verify that your motherboard uses the TRX50 chipset and supports registered DIMMs at 1.40V. The modules need an AMD EXPO-capable BIOS to load the 7200MHz profile; without it they will fall back to standard JEDEC speeds.

Sustained Load Behaviour

On-die ECC and the registered buffer maintain data integrity during continuous compute tasks. The 10-layer PCB and Hynix ICs are tested for stability at the rated voltage, while the onboard PMIC manages power delivery across all four modules under prolonged workloads.

Questions about this item

What comes in the box and is anything else needed to install the 4 x 16 GB DDR5 RDIMM kit?

The kit includes four 16 GB DDR5 288-pin registered DIMMs with heat spreaders. No additional parts are required for installation on a compatible TRX50 workstation motherboard.

How do I decide between this 64 GB 7200 MHz CL34 kit and other capacity or speed options?

Choose this 64 GB kit when you need four ranked 1Rx8 modules running at 7200 MHz with CL34 timings at 1.40 V via AMD EXPO on TRX50. Other capacities or speeds will have different part numbers and timing tables.

What does the 7200 MHz rating actually deliver once the modules are seated in a Threadripper PRO 7000 system?

With the AMD EXPO profile enabled, each DIMM runs at 7200 MHz (PC5-57600) with 34-45-45-112 timings at 1.40 V, providing ECC registered operation on the TRX50 platform.
