Exact DDR5 ECC RDIMM kit

This 128GB kit contains four 32GB DDR5-6400 registered ECC modules built to the PC5-51200 standard. It is designed for servers and workstations that require registered memory with error correction.

Registered 288-pin form factor

The RDIMM layout buffers the address and command signals so the memory controller can drive all four slots at full population. Each module runs at 1.1V with CL52 latency and uses a 1Rx4 organisation without a heat spreader.

ASRock Rack GNRAP2D24G-2L+ validated

The kit is tested for full compatibility with the named motherboard, matching its DDR5-6400 speed, voltage, rank structure and registered ECC requirement. Systems that need UDIMM, SODIMM or non-ECC memory cannot use this kit.

Questions about this item

What DDR5 speed does the 128GB kit run at and what bandwidth does that provide?

The kit operates at DDR5 6400 (PC5 51200), delivering the rated 51200 MB/s bandwidth your server's memory controller expects.

Does the 288-pin RDIMM form factor match the ASRock Rack GNRAP2D24G-2L+ motherboard slots?

Yes, these are 288-pin Registered RDIMMs, the exact form factor the board requires — not UDIMM or SODIMM.

What is the correct DIMM population order for all four 32GB modules?

Consult the motherboard manual for the approved population sequence; the kit includes four 32GB 1Rx4 RDIMMs that must be installed in the specified slot order.
