Server-grade DDR5 RDIMM

This 64GB DDR5 module runs at 4800 MT/s with CL40 latency and 1.1V operation. It uses a 288-pin registered ECC design built for the ASRock Rack GENOA2D24G-2L+ motherboard. The 2Rx4 organisation matches the board's memory controller requirements exactly.

DDR5 platform constraints

DDR5 RDIMMs require a motherboard with registered DIMM slots and a memory controller that supports ECC and the specified voltage. Mixing unbuffered or non-ECC modules will prevent the system from posting. Population rules and maximum capacity per channel are defined by the motherboard manual, not the module itself.

2Rx4 registered ECC organisation

The dual-rank by-four configuration with on-die ECC determines whether the memory controller can address the full 64GB at rated speed. Systems expecting single-rank or x8 organisation may not recognise the capacity or may downclock the module. Verify the motherboard's qualified vendor list for this exact rank and width before purchase.

Questions sur cet article

Should I select the 64GB 2Rx4 module or a different capacity for my ASRock Rack GENOA2D24G-2L+?

Choose this 64GB 2Rx4 RDIMM when your motherboard manual lists 64GB registered DIMMs as supported and calls for the 2Rx4 organisation. The exact rank, voltage and timing match the board's qualified-vendor list so the module is recognised at full capacity and runs at its rated 4800 speed.

What does the DDR5 4800 rating mean once the module is installed in the server?

DDR5 4800 means the module operates at 4800 MT/s with CL40 latency at 1.10V. The registered buffer reduces electrical load on the memory controller, allowing full-speed operation even with every slot populated, while on-die ECC corrects single-bit errors before they reach the OS.

How does the 288-pin RDIMM interface and registered ECC design affect real-world limits?

The 288-pin RDIMM form factor fits only DDR5 registered DIMM slots; it will not work in UDIMM or SODIMM sockets. Registered buffering lets the memory controller drive maximum capacity per channel, and ECC provides single-bit error correction with detection of multi-bit faults, preventing silent data corruption in production workloads.
