128GB Quad-Channel DDR5-6800 ECC Kit

This 128GB kit contains four 32GB DDR5-6800 RDIMMs built for AMD Threadripper 7000X workstations. Registered ECC operation and AMD EXPO profiles target professionals who need maximum bandwidth with error correction for rendering, simulation and data-intensive workloads. The modules run at CL34 34-45-45-108 timings on 1.40V.

Registered 288-Pin RDIMM Design

Each module uses a registered 288-pin DDR5 form factor without a heat spreader, relying on chassis airflow for cooling. Registered buffering reduces electrical load on the memory controller, enabling stable four-channel population on TRX50 motherboards. The bare PCB layout fits dense server configurations where tall spreaders would block adjacent slots or airflow paths.

AMD EXPO Overclock Limits

Rated DDR5-6800 speed and CL34 timings are only guaranteed when the CPU memory controller and motherboard firmware support the EXPO profile. Stability at 6800 MT/s varies by silicon quality and board topology; systems that cannot sustain the profile will fall back to standard JEDEC speeds. Buyers without TRX50 platforms or Threadripper 7000X CPUs cannot reach the advertised frequency.

Questions about this item

Does this DDR5 6800 kit run at the rated speed through AMD EXPO on a TRX50 motherboard?

The kit uses an AMD EXPO profile to reach DDR5 6800 with CL34-45-45-108 timings at 1.40 V. Stable operation depends on the motherboard QVL and the CPU memory controller.

What physical slot and channel layout do the four 32 GB RDIMMs require?

Four 288-pin DDR5 RDIMM modules fill a quad-channel configuration on a compatible AMD TRX50 motherboard with four memory slots.

How do I enable the rated 6800 MT/s speed after installing the modules?

Enter the BIOS, select the AMD EXPO profile for this kit, save and reboot; skipping the EXPO step leaves the modules at JEDEC default speeds.
