Speed DDR5 6800 (PC5 54400)

  • 128 GB capacity across eight 16 GB modules for large workloads
  • DDR5 6800 speed with CL34 latency for responsive data access
  • Registered ECC design protects data integrity in critical tasks
  • AMD EXPO profile enables one-click overclocking on WRX90 platforms
  • Patented RCD and PMIC micro-heatsinks lower module temperatures

WRX90 Workstation Memory Kit

This 128 GB kit delivers eight 16 GB DDR5 registered DIMMs built for AMD Threadripper PRO 7000 series workstations. The modules run at 6800 MT/s with CL36 timings at 1.40 V and include on-die ECC for data integrity in professional workloads.

AMD EXPO Profile Constraints

The EXPO profile sets 6800 MT/s at CL34, yet the SPD table lists CL36-46-46-92 at 1.40 V. Systems that only read JEDEC defaults will drop to lower speeds unless the firmware applies the EXPO overclock. Memory controllers that cannot sustain 1.40 V will also limit the achievable frequency.

Registered DIMM Installation Notes

Each stick carries a 10-layer PCB, micro-heatsinks on the RCD and PMIC, and a standard heat spreader. The registered buffer adds one cycle of latency, so the platform must support RDIMM topology. Mixing these modules with unbuffered DIMMs or populating slots the WRX90 manual forbids will prevent the system from posting.

Questions sur cet article

Should I pick the 128GB kit or a smaller capacity for my WRX90 workstation?

This kit provides 128GB across eight 16GB modules, filling all channels on a WRX90 board for maximum bandwidth and ECC capacity.

What does the 6800MHz speed with CL34 timing deliver in a Threadripper PRO 7000 system?

The AMD EXPO profile sets DDR5-6800 at CL34-46-46-92 and 1.4V, giving high throughput with on-die ECC for data integrity under load.

How does the 288-pin DDR5 RDIMM interface limit performance on WRX90 motherboards?

As a registered DIMM, it uses the onboard RCD and PMIC with micro-heatsinks to maintain signal integrity at 6800MHz across all eight slots.
