  • 384 GB total capacity from four 96 GB modules for dense server memory configurations
  • DDR5-4800 (PC5-38400) speed with CL40 latency matches the motherboard's rated timing
  • 2Rx4 Registered ECC design offloads the memory controller and corrects single-bit errors on the fly
  • 10 V operating voltage reduces power draw per module in fully populated systems
  • Verified compatibility with ASRock Rack GENOAD12M3-2Q motherboard ensures correct rank, voltage and form factor recognition

Capacity and compatibility

This NEMIX RAM kit delivers 384GB of DDR5 memory across four 96GB registered DIMMs. It is built for the ASRock Rack GENOAD12M3-2Q motherboard and matches the board's required 288-pin RDIMM form factor, 2Rx4 rank structure and 1.1V operating voltage.

Upgrade path and fit

The kit replaces lower-capacity DDR5 RDIMM sets or mixed-rank configurations that prevent full-slot population at rated speed. The jump is worth it when the workload demands the full 384GB at DDR5-4800 with ECC and registered buffering, and the motherboard manual confirms support for this exact capacity and population order.

Installation notes

Modules install into the motherboard's 288-pin DDR5 slots following the population sequence in the system manual. The most common issue is ignoring the approved DIMM order, which can prevent boot or reduce the recognised capacity. Verify the configuration guide before seating the modules.

Questions about this item

Does this kit require 288-pin DDR5 RDIMM slots on the ASRock Rack GENOAD12M3-2Q motherboard?

Yes, each module is a 288-pin DDR5 RDIMM, the exact form factor the ASRock Rack GENOAD12M3-2Q requires. It will not fit UDIMM or SODIMM sockets.

What population order should I follow when installing the four 96 GB modules on the ASRock Rack GENOAD12M3-2Q?

Consult the motherboard manual for the approved DIMM population sequence; the board's memory-controller rules dictate which slots must be filled first for full 384 GB recognition.

When should the 2Rx4 registered ECC modules be replaced in a production server?

Replace them if ECC logs show rising correctable-error counts, if the system fails POST with all four installed, or when a firmware update changes the qualified-vendor list for DDR5-4800 RDIMMs.
