Speed DDR5 6400 (PC5 51200)

  • 128 GB capacity with eight 16 GB modules for large workloads
  • DDR5 6400 MHz CL32 speed for high-throughput computing
  • ECC registered DIMM protects data integrity in critical tasks
  • Patented RCD and PMIC micro-heatsinks lower module temperatures
  • AMD EXPO profile enables one-click overclocking on WRX90 workstations

Purpose-built workstation memory

The V-color TRA516G64S832O kit delivers 128GB of DDR5 registered ECC memory across eight 16GB modules. It runs at 6400MHz with CL32 timings and 1.4V voltage on AMD WRX90 workstation motherboards. The AMD EXPO profile enables validated overclocking for Threadripper PRO 7000 series processors.

Suited for registered ECC workloads

This kit targets professionals building or upgrading WRX90 workstations who require registered DIMMs with on-die ECC for data integrity. It is not for consumer desktop boards that accept only unbuffered memory, nor for systems limited to lower voltages or speeds. Buyers needing different capacities or non-registered modules should look elsewhere.

Straightforward installation with thermal care

The 288-pin RDIMMs install like standard DDR5 modules, but the registered buffer and PMIC micro-heatsinks add height — verify cooler clearance before fitting all eight sticks. The 10-layer PCB and SK Hynix ICs undergo automated sorting, yet mismatched BIOS versions on WRX90 boards can prevent EXPO activation at 6400MHz.

Preguntas sobre este artículo

Must my motherboard have eight DDR5 RDIMM slots to use all 128 GB?

The kit contains eight 16 GB modules, so eight 288-pin DDR5 RDIMM slots are required to install the full 128 GB capacity.

Will the AMD EXPO profile load on a Threadripper PRO 7000 series CPU in a WRX90 board?

The memory is built for WRX90 workstation motherboards with Threadripper PRO 7000 series processors and includes an AMD EXPO profile for automatic overclocking to 6400 MHz CL32.

How do I confirm the kit is running at 6400 MHz with CL32-39-39-102 timings?

After enabling the EXPO profile in the BIOS, check the memory speed and timing readouts in the firmware or a system-information utility to verify 6400 MHz and the stated latencies.
