Speed DDR5 4800 (PC5 38400)

  • ECC registered design protects workstation data integrity
  • 128 GB capacity across eight 16 GB modules handles large workloads
  • DDR5 4800 speed with CL40-39-39-77 timings delivers responsive throughput
  • Patented RCD and PMIC micro-heatsinks improve cooling efficiency
  • AMD EXPO profile simplifies overclocking on WRX90 Threadripper platforms

WRX90 Workstation Memory Kit

This 128GB kit contains eight 16GB DDR5 registered DIMMs built for AMD Threadripper WRX90 workstation motherboards. Each module runs at 4800MHz with CL40 latency and operates at 1.25V. The memory includes ECC error correction and AMD EXPO profile support for simplified configuration.

Thermals And Power Draw

Patented RCD and PMIC micro-heatsinks on every module improve cooling efficiency under sustained workloads. An on-board thermal sensor monitors temperature across the 0 to 85 °C operating range to prevent overheating. Registered buffering and 1.25V operation help maintain stable power delivery during extended compute tasks.

Bundled Extras And Software Impact

No extra cables, adapters or software utilities are included with the kit. AMD EXPO profile data is stored on the DIMMs themselves, allowing the BIOS to apply the 4800MHz CL40 timings automatically without user intervention. The heat spreader is integrated and not removable.

Questions sur cet article

How do I install the 8×16GB DDR5 R-DIMM kit into a WRX90 workstation and what step is often missed?

Insert each 288-pin module into the motherboard's DDR5 slots until the retention clips click, then enable the AMD EXPO profile in BIOS so the kit runs at 4800MHz CL40 instead of the default JEDEC speed.

What maintenance or replacement will the V-color WRX90 OC R-DIMM need over time?

The modules have a patented RCD and PMIC micro-heatsink plus an on-board thermal sensor; keep case airflow clear so the sensor never sees temperatures above the 0–85°C operating range, otherwise no scheduled maintenance is required.

What limit appears first when the 128GB kit runs sustained workloads on a Threadripper WRX90 system?

The on-die thermal sensor will throttle the memory if the 85°C operating ceiling is reached, so sustained performance is bounded by the cooling solution's ability to keep the registered DIMMs below that temperature.
