  • 768GB total capacity from 12 x 64GB modules maximises server memory density
  • DDR5 4800MHz PC5-38400 speed matches the motherboard's rated frequency for full performance
  • CL40 CAS latency at 1.1V delivers the exact timing and voltage the memory controller expects
  • ECC and Registered RDIMM architecture corrects single-bit errors and buffers signals for stable full-population operation
  • 288-pin 2Rx4 form factor fits the ASRock Rack GENOAD12M3-2Q motherboard's required DIMM type and rank configuration

Capacity and compatibility

This NEMIX RAM kit delivers 768GB of DDR5 registered ECC memory across twelve 64GB modules. It is built for the ASRock Rack GENOAD12M3-2Q motherboard and matches the board's DDR5 4800 PC5-38400 specification.

Who this suits and who it does not

The 2Rx4 registered design with ECC suits servers that require full-slot population and single-bit error correction. Systems limited to UDIMM or SODIMM form factors, or those without registered ECC support, cannot use this kit.

Installation notes

Each module uses the standard 288-pin RDIMM form factor and operates at 1.1V, so it seats in the board's DDR5 slots without extra power cables. The main risk is ignoring the motherboard manual's population order, which can prevent the system from recognising the full 768GB capacity.

Questions about this item

What motherboard must I already have for this 12-module DDR5 kit to be recognised at full 768GB capacity?

The kit is validated for the ASRock Rack GENOAD12M3-2Q motherboard running DDR5 4800 PC5-38400; install all twelve 288-pin RDIMMs in the slots specified by that board's manual.

Will the 2Rx4 registered ECC modules run reliably in the remaining DDR5 slots if I keep older RDIMMs of a different rank or speed?

Mixing ranks, speeds or voltages is not supported; the board's memory controller expects every populated slot to match the 4800MHz 1.1V CL40 2Rx4 specification exactly.

How can I confirm the 768GB kit is operating at its rated 4800MHz CL40 after installation?

Enter the BIOS or use a hardware inventory tool and verify the memory frequency reads 4800 MT/s, CAS latency shows CL40, and total capacity reports 768GB with ECC active.
