  • DDR5 6400 speed with CL52 latency delivers rated performance the memory controller expects
  • Registered ECC architecture offloads the controller and corrects single-bit errors on the fly
  • 1V operating voltage matches the board's specification for stable full-capacity operation
  • 288-pin RDIMM form factor fits the ASRock Rack GNRAP2D24G-2L+ motherboard's required slot type

Exact-Match Server Memory

This 128GB DDR5 ECC RDIMM module is built for administrators upgrading an ASRock Rack GNRAP2D24G-2L+ motherboard. Registered architecture and on-die ECC protect data integrity when every slot is populated at full capacity. The module arrives new and ready for installation.

Thermals Power Noise

Operating at 1.1V, the module draws minimal power and produces no fan noise because it has no integrated heat spreader. Passive cooling relies entirely on chassis airflow directed by the server platform. No active thermal components are present on the DIMM itself.

Registered ECC RDIMM Form Factor

The 288-pin Registered RDIMM format with 2Rx4 organization is the single specification that determines compatibility. This board requires buffered modules and will not accept unbuffered UDIMMs or SODIMMs. Verify your system manual for supported population rules before purchase.

Questions about this item

How do I install this 288-pin DDR5 RDIMM in the ASRock Rack GNRAP2D24G-2L+ and what slot order should I follow?

Power down the server, open the chassis, and insert the module into the DDR5 slots following the exact population sequence shown in the motherboard manual; the registered design requires the correct order for full 128 GB recognition at 6400 MHz.

Will this ECC registered RDIMM need any firmware updates or component swaps during its service life?

The module itself has no user-serviceable parts; ECC correction runs automatically on the DRAM, so no firmware flashes or chip replacements are required — only standard server dust cleaning and thermal monitoring.

What is the first limitation I will hit when running this 128 GB kit at 6400 MHz continuously?

Sustained load is bounded by the CL52 latency at 1.1 V; the registered buffer and ECC overhead set the practical throughput ceiling before thermal throttling becomes a factor.
