Two green DDR5 RDIMM modules without heat spreaders in a 64GB kit

NEMIX RAM

NEMIX RAM 64GB (2x32GB) DDR5 6400 CL52 1Rx4 ECC RDIMM memory upgrade

SKU CH-S0EZ-8M30D

64 GB DDR5 ECC registered server memory kit in two 32 GB modules running at 6400 MT/s with CL52 latency and 1.1 V, validated for the ASRock Rack GNRAP2D24G-2L+ motherboard

  • Exact DDR5-6400 spec match ensures full-speed recognition
  • Registered ECC architecture prevents silent data corruption
  • 1Rx4 dual-rank layout enables full-capacity population
  • 1V operation reduces server power draw
  • Verified fit for ASRock Rack GNRAP2D24G-2L+ motherboard

Exact-fit server upgrade

This 64GB kit delivers two 32GB DDR5 RDIMMs built to the precise 1Rx4, 1.1V, CL52 specification your server's memory controller expects. Registered ECC architecture offloads the controller and corrects single-bit errors on the fly, keeping every slot stable at full capacity.

Registered RDIMM form factor

The modules use the 288-pin Registered DIMM format required by the target platform; they are not UDIMMs or SODIMMs and will not fit boards that demand those form factors. Only systems that accept registered ECC DDR5 at this rank and voltage will recognise the kit at its rated 6400 speed.

Suited for ASRock Rack GNRAP2D24G-2L+ owners

Builders populating that specific motherboard with a validated, matched pair gain full-capacity operation without population guesswork. Buyers who need unbuffered memory, a different rank structure, or compatibility with other server models should verify their manual before ordering.

Questions about this item

Will the DDR5-6400 speed run at 6400 MT/s on the ASRock Rack GNRAP2D24G-2L+?

The kit is spec-matched to the board's DDR5-6400 memory controller, so it is recognised at full capacity and operates at its rated 6400 MT/s with CL52 timings.

Does the PC5-51200 rating limit bandwidth on this motherboard?

PC5-51200 is the peak transfer rate for DDR5-6400; the board's memory controller caps usable bandwidth at that level, so the modules run at their full rated throughput.

Will these 288-pin RDIMMs fit the GNRAP2D24G-2L+ DIMM slots?

Yes, the 288-pin Registered RDIMM form factor matches the slots this board requires; UDIMM or SODIMM modules would not fit.
