Speed DDR5 6800 (PC5 54400)

Rank 2Rx8

  • 128 GB capacity across four 32 GB modules
  • 6800 MHz DDR5 speed with CL34 latency
  • Registered ECC design detects and corrects data errors
  • AMD EXPO profile enables one-click overclocking on TRX50
  • On-board PMIC and thermal sensor maintain stable operation

Capacity and configuration

This kit provides 128GB across four 32GB modules in a 288-pin DDR5 RDIMM form factor. It is built for AMD TRX50 workstation motherboards using Threadripper PRO 7000 series processors and is not compatible with standard desktop or laptop platforms.

Speed and headroom

Rated at 6800MHz with CL34 timings of 34-46-46-92 and 1.40V, the modules use Hynix ICs on a 10-layer PCB with AMD EXPO profiles for validated overclocking. Registered buffering and on-die ECC maintain data integrity under sustained loads where unbuffered memory would show errors.

Interface limits

DDR5 architecture doubles bandwidth over DDR4 through two independent 40-bit channels per DIMM, yet the registered clock driver and ECC logic add latency that caps maximum frequency below unbuffered equivalents. The on-board PMIC manages power delivery at 1.40V, and the thermal sensor prevents throttling during prolonged compute tasks.

Questions about this item

Will these 6800MHz DDR5 RDIMMs run at rated speed on my existing TRX50 motherboard with AMD EXPO enabled?

Yes, the kit includes an AMD EXPO profile for DDR5 6800 CL34 at 1.4V, so a TRX50 board with EXPO support will apply the rated frequency and timings automatically.

How can I verify the on-die ECC and the thermal sensor are active after installation?

The module provides on-die ECC and a built-in temperature-monitoring sensor; both functions are reported by the platform firmware and can be confirmed in BIOS or with standard hardware-monitoring utilities.

Does the package contain four 32GB sticks and is anything else required for a TRX50 workstation?

The box contains four 32GB DDR5 288-pin RDIMMs for a total of 128GB; no additional components are needed for a compatible TRX50 workstation motherboard.
