Exact DDR5 server kit

This NEMIX RAM kit provides 192 GB in two 96 GB DDR5-6400 Registered ECC RDIMMs. It is built for administrators upgrading the ASRock Rack GNRAP2D24G-2L+ motherboard with memory that matches the board’s exact rank, voltage and timing requirements.

Registered ECC fitment

Each module is a 288-pin RDIMM rated at 1.1 V with CL52 latency and a 2Rx4 organisation. The registered architecture buffers address and command signals so the memory controller can run every slot fully populated, while on-die ECC corrects single-bit errors before they affect workloads.

For validated platform upgrades

This kit suits IT teams that need a verified, full-capacity upgrade for the named ASRock Rack board and want lifetime replacement coverage. It is not for builders using consumer UDIMM or SODIMM slots, nor for systems that require a different DDR generation, voltage or rank configuration.

Questions about this item

Will the 2Rx4 rank configuration limit how many of these 96GB modules I can install on my ASRock Rack GNRAP2D24G-2L+?

The 2Rx4 organisation lets each 96GB module present two ranks to the memory controller, so population limits depend on the motherboard's maximum rank-per-channel spec; check the board manual for the exact slot sequence and total rank ceiling.

How much heat will the 1.1V DDR5 6400 RDIMMs generate when the server runs 24/7?

At 1.1V the modules draw modest power, and because they lack a heat spreader they rely on chassis airflow; sustained loads stay cool if your server provides the directed cooling the board design expects.

Does the ASRock Rack GNRAP2D24G-2L+ need a specific BIOS revision before it will recognise the 192GB kit at DDR5 6400?

The kit is validated for that motherboard at DDR5 6400 CL52, but the board manual lists any required BIOS version for full capacity and speed support; apply that update before installing the modules.
