Capacity and purpose

This 128GB kit contains eight 16GB DDR4 RDIMMs built for the ASRock Rack ROMED8-2T motherboard running AMD EPYC processors. It targets administrators who need registered ECC memory for stable server operation.

Registered ECC RDIMM

Each module is a 288-pin DDR4 3200 RDIMM with CL22 latency, 1.2V operation and 2Rx8 organisation. The registered buffer and error-correction code are the single specification that determines compatibility with the target platform.

Build integration

The kit fills all eight slots on the ROMED8-2T, delivering the full 128GB capacity in one matched set. It requires a motherboard that supports registered ECC DDR4 and an AMD EPYC CPU; it will not work in consumer boards or unbuffered memory channels.

Questions about this item

What real-world throughput does the PC4-25600 rating deliver in a server?

The kit runs at DDR4 3200, giving a peak transfer rate of 25 600 MB/s per module; actual sustained bandwidth depends on the memory controller and workload.

How does the registered ECC design affect compatibility and error handling?

Registered buffering reduces electrical load on the memory controller, while ECC detects and corrects single-bit errors, making the kit suited for multi-DIMM server boards that require registered modules.

Will the 288-pin RDIMMs fit standard server DIMM slots without a heat spreader?

Yes, the 288-pin DDR4 RDIMM form factor matches standard server slots; the modules have no heat spreader, so they occupy only the nominal slot height.
