Capacity and purpose

This 384GB kit contains four 96GB DDR5 Registered ECC RDIMM modules rated at 6400MHz with CL52 latency and 1.1V operation. It is built for servers and workstations that require maximum memory density with error correction and registered buffering for stability under full population.

Who this suits

The kit is designed for the ASRock Rack GNRAPD12DNO motherboard and matches its DDR5 6400MHz PC5-51200 2Rx4 specification exactly. It is not for systems that accept only unbuffered UDIMM or SODIMM modules, nor for platforms limited to lower DDR5 speeds or different rank configurations.

Build integration

Each module uses the 288-pin RDIMM form factor and draws 1.1V, so the motherboard must support Registered ECC DDR5 at this voltage and population rule. The registered architecture offloads the memory controller, allowing all four slots to run at rated capacity while ECC corrects single-bit errors without interrupting operation.

Highlights

  • 384 GB capacity across four 96 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
  • 10 V operation matches the platform's memory controller specification exactly
  • Verified fit for ASRock Rack GNRAPD12DNO motherboard with 288-pin RDIMM form factor

Questions about this item

What motherboard is required to install this 384GB DDR5 6400 CL52 ECC RDIMM kit?

The kit is verified for the ASRock Rack GNRAPD12DNO motherboard, which accepts 288-pin DDR5 RDIMM modules at 1.1V with 2Rx4 organisation.

Will this 2Rx4 Registered DDR5 6400 kit run correctly with existing 1Rx4 DDR5 RDIMMs in the same server?

Mixing ranks can change the memory controller's addressing and timing; the board manual specifies approved population rules for full-speed operation with 2Rx4 modules.

How do I confirm the kit is running at DDR5 6400 CL52 with ECC active after installation?

Check the BIOS memory information or OS tools such as dmidecode to verify 6400 MT/s, CL52 timings, 1.1V and ECC enabled across all four 96GB DIMMs.
