128GB DDR5-6400 Registered ECC Kit

This 128GB kit contains two 64GB DDR5 RDIMMs rated at 6400MHz PC5-51200 with CL52 latency and 1.1V operation. The modules use a 2Rx4 registered design with ECC for error correction. They are built as an exact-match upgrade for the ASRock Rack GNRAP2D24G-2L+ motherboard. The 288-pin form factor fits the server board's DDR5 RDIMM slots.

Suited For Verified Server Platforms

This memory serves administrators upgrading or populating the ASRock Rack GNRAP2D24G-2L+ motherboard where registered ECC DDR5 is required. Builders needing unbuffered UDIMMs, SODIMMs, or non-ECC modules for workstation or consumer boards cannot use this kit. Systems that do not support 2Rx4 registered DIMMs or the DDR5-6400 speed grade should select different memory.

2Rx4 Registered ECC Architecture

The dual-rank registered layout with on-die ECC allows full-capacity population across all slots while offloading the memory controller. This specific 2Rx4 organization and 1.1V voltage must match the motherboard's qualified vendor list for stable operation at the rated 6400MHz speed.

Questions about this item

Will the 288-pin DDR5 RDIMM modules fit the ASRock Rack GNRAP2D24G-2L+ motherboard?

Yes, the 288-pin Registered DDR5 RDIMM form factor matches the slots on the ASRock Rack GNRAP2D24G-2L+ motherboard and the kit is verified for that platform.

What is the correct installation order for the two 64 GB modules on this motherboard?

Install the two 64 GB modules in the DIMM slots specified by the ASRock Rack GNRAP2D24G-2L+ manual; the board's population rules dictate which channels must be filled first for the 128 GB kit to be recognised at full speed.

Does the registered ECC design reduce long-term maintenance compared with unbuffered memory?

Registered architecture offloads the memory controller and on-die ECC corrects single-bit errors, lowering the chance of silent data corruption and unplanned reboots over the module's service life.
