  • 256 GB total capacity from two 128 GB modules for maximum server density
  • DDR5-6400 speed with CL52 latency delivers rated throughput for demanding workloads
  • Registered ECC architecture corrects single-bit errors and stabilises fully populated slots
  • 1 V operation matches platform spec for efficient, reliable performance
  • Validated for ASRock Rack GNRD16DNO and GNRD16QM3-NL motherboards ensuring correct fitment

Exact-match server upgrade

This 256 GB kit contains two 128 GB DDR5 RDIMMs rated at 6400 MT/s with CL52 latency and 1.1 V operation. Registered ECC architecture with 2Rx4 organisation is designed for full-capacity population on supported ASRock Rack platforms.

Verify platform rules first

Confirm that your ASRock Rack GNRD16DNO or GNRD16QM3-NL motherboard accepts 288-pin registered DDR5 modules at the stated speed and rank configuration. Check the manual for approved DIMM population order, maximum capacity per channel and any BIOS version requirements before ordering.

Registered ECC for dense population

The registered buffer reduces electrical load on the memory controller, allowing every slot to run at rated speed while ECC corrects single-bit errors in flight. This kit frees you from mixing ranks or speeds and delivers the full 256 GB in a validated two-module configuration.

Perguntas sobre este artigo

Does the 256 GB kit include both 128 GB modules or do I need to buy a second kit?

The package contains a matched pair of two 128 GB RDIMMs giving 256 GB total, so no additional kit is required.

Should I choose the 256 GB 2Rx4 kit or a different capacity for my ASRock Rack GNRD16DNO?

Select this 256 GB 2Rx4 kit if your motherboard manual lists 128 GB per slot as supported; otherwise pick the capacity that matches the approved population table.

Will the DDR5 6400 CL52 rating run at that speed once installed in the GNRD16QM3-NL?

Yes, the modules are spec-matched to the board's DDR5 6400 memory controller so they operate at 6400 MT/s with CL52 timing when populated per the manual.
