Show 4 more configurations
  • 128 GB capacity in a matched 4 × 32 GB kit for full server population
  • DDR5 6400 MHz speed with CL52 latency for rated bandwidth performance
  • Registered ECC design corrects single-bit errors and buffers the memory controller
  • 1 V operation at 1Rx4 rank for exact controller compatibility
  • Validated for ASRock Rack GNRD16DNO and GNRD16QM3-NL motherboards

Exact-fit server kit

This 128 GB kit contains four 32 GB DDR5-6400 registered ECC RDIMMs built to the precise 1Rx4, 1.1 V, CL52 specification that ASRock Rack GNRD16DNO and GNRD16QM3-NL motherboards require. The modules arrive new and are validated for full-capacity recognition at rated speed on those platforms.

Registered ECC DDR5 limits

Registered buffering lets the memory controller drive every slot at full population without signal degradation, while on-die ECC corrects single-bit errors before they reach the OS. DDR5-6400 (PC5-51200) is the maximum JEDEC data rate this kit supports; any higher frequency would need motherboard and CPU support not guaranteed by this specification.

Verify before ordering

Confirm your server or motherboard manual lists 128 GB total capacity, 1Rx4 registered DIMMs, and the exact population sequence for four modules. The 288-pin RDIMM form factor will not fit UDIMM or SODIMM slots, and boards limited to lower speeds or unbuffered memory cannot use this kit.

Questions about this item

Should I choose the 128GB kit or a different capacity for my ASRock Rack GNRD16DNO?

This kit provides 128GB total across four 32GB modules. Check your motherboard manual for the maximum supported capacity and approved population rules before deciding.

What does the DDR5 6400MHz rating mean once the modules are installed in the server?

The modules will run at 6400 MT/s with CL52 latency at 1.1V, delivering the full rated throughput the memory controller expects when all four slots are populated.

How does the 288-pin RDIMM interface and registered design affect what the system can do?

The 288-pin RDIMM form factor fits only DDR5 RDIMM slots. Registered buffering lets the memory controller drive all four slots at full capacity, while ECC corrects single-bit errors on the fly.
