128 GB DDR5 ECC RDIMM for ASRock Rack

This NEMIX RAM module delivers 128 GB of DDR5 registered ECC memory rated at 6400 MT/s with CL52 latency and 1.10 V operation. It uses a 2Rx4 organization and 288-pin RDIMM form factor built with major OEM DRAM chips. The kit is verified for the ASRock Rack GNR2D16-2T motherboard.

Who should buy this and who should not

Server administrators populating the GNR2D16-2T with the exact registered ECC specification the board expects will get full-capacity recognition and error correction. Builders needing unbuffered UDIMMs, SODIMMs, non-ECC modules, or a different speed, voltage, or rank configuration cannot use this part.

Registered ECC with 2Rx4 rank

The 2Rx4 registered ECC architecture is the single specification that determines compatibility. The memory controller on the target motherboard requires this exact rank structure and buffering type to initialize at rated speed and capacity.

Questions about this item

How can I verify the memory is running at DDR5 6400 with CL52 after installation?

Enter the BIOS or UEFI and confirm the memory speed reads 6400 MT/s and the CAS latency shows 52. The registered ECC design also lets the system log corrected errors, which you can review in the OS event viewer to confirm ECC is active.

What does the kit contain and do I need any extra parts?

The kit includes one 128 GB 288-pin DDR5 RDIMM module rated at 1.1 V. No heat spreader, cables or additional components are supplied; the motherboard slot provides all required power and signalling.

Which capacity or version should I choose for the ASRock Rack GNR2D16-2T?

This specific part number MR51200-724K1 is the exact-match 128 GB 2Rx4 registered ECC RDIMM validated for the GNR2D16-2T at DDR5 6400. Select this version when you need the full 128 GB per DIMM slot.
