Capacity and fit

This 128GB kit provides four 32GB DDR4 2400 modules built as ECC registered RDIMMs for the ASRock Rack EPYCD8-2T motherboard. It targets administrators who need maximum registered memory capacity in that specific platform.

Sustained operation

Each module runs at 1.2V with CL17 timing and a 2Rx4 organisation, allowing the memory controller to maintain error correction during continuous server workloads. The registered buffer reduces electrical load on the memory bus so stability holds under prolonged utilisation.

Installation notes

The 288-pin RDIMMs slot into the board's DDR4 sockets without a heat spreader, so clearance is minimal. Builders must populate all four channels in the order the manual specifies; mixing unbuffered DIMMs or skipping slots will prevent the system from posting.

Questions about this item

How much heat does this 1.2 V DDR4 kit produce during continuous server workloads?

Each module runs at 1.20 V with no heat spreader, so thermal output is low and relies on standard chassis airflow for cooling.

What motherboard features are required to support these 2Rx4 registered ECC DIMMs?

The board must provide 288-pin DDR4 slots, registered ECC support, and a memory controller that accepts 2Rx4 organisation at 2400 MT/s.

Will these 2400 MT/s modules work alongside existing 2666 MT/s DDR4 RDIMMs in the same ASRock EPYCD8-2T system?

Yes, the faster DIMMs will down-clock to 2400 MT/s and the kit will operate at CL17 across all populated channels.
