  • 384 GB total capacity across 12 modules of 32 GB each
  • DDR5 6400 speed with CL52 latency for rated performance
  • 1 V operation matches server memory controller requirements
  • Registered ECC design corrects single-bit errors and supports full population
  • 288-pin RDIMM form factor verified for ASRock Rack GNRAP2D24G-2L+

Exact-fit server kit

This 384GB kit provides twelve 32GB DDR5 RDIMMs rated at 6400 MT/s with CL52 latency and 1.10V operation. Registered ECC architecture and 1Rx4 organisation allow full population on the ASRock Rack GNRAP2D24G-2L+ motherboard without downclocking. The modules match the board's required 288-pin RDIMM form factor and memory-population rules.

Buyers needing validated capacity

Server administrators who must populate every DIMM slot at the rated 6400 speed with ECC protection will use this kit. Workstations or desktop boards that accept only unbuffered UDIMMs cannot use these registered modules. Systems limited to lower maximum capacities or different pin layouts should look elsewhere.

Capacity and headroom

Twelve ranks of 32GB each deliver 384GB of addressable memory for multi-socket workloads such as virtualisation clusters or in-memory databases. Full population runs at the rated 6400 MT/s CL52 with registered buffering keeping signal integrity intact. Workloads exceeding 384GB or requiring higher frequencies than 6400 will need a different platform.

Questions about this item

Does this 12-module 384GB DDR5 kit require an ASRock Rack GNRAP2D24G-2L+ motherboard with 288-pin RDIMM slots to operate?

Yes, the kit is built for the ASRock Rack GNRAP2D24G-2L+ motherboard and uses 288-pin registered DDR5 RDIMMs that only fit that slot type.

Will these 1Rx4 CL52 DDR5-6400 modules run at their rated speed when installed in the recommended population order on that board?

The modules are spec-matched to the board's DDR5-6400 PC5-51200 timing and 1Rx4 registered layout so they operate at full speed when populated per the manual.

How can I confirm the server recognises all 384GB at DDR5-6400 with ECC active after installation?

Check the BIOS memory summary or OS tools such as dmidecode; they should show 12 x 32GB modules at 6400 MT/s, 1.1V, CL52 with ECC enabled.
