Exact-match server upgrade

This 768GB kit delivers twelve 64GB DDR5 4800 RDIMMs built to the ASRock Rack GENOA2D24G-2L+ motherboard's exact specifications. Registered ECC modules with 2Rx4 organisation and 1.1V operation are recognised at full capacity and rated speed without manual tuning.

Capacity and headroom

Twelve slots filled with 64GB DIMMs provide 768GB of addressable memory for multi-socket workloads that scale across all channels. The registered buffer keeps electrical loading low so every slot runs at the rated frequency, while on-die ECC corrects single-bit errors before they reach the application layer.

DDR5 interface limits

The PC5-38400 standard caps transfer rate at 4800 MT/s and CAS latency at CL40, so bandwidth and latency are fixed by the memory controller rather than the modules. Population rules in the motherboard manual determine which slot combinations are valid; unsupported configurations will not train at the rated speed.

Questions sur cet article

Will this 12-module 768GB DDR5-4800 kit work if I keep some of my existing DDR5 RDIMMs in the ASRock Rack GENOA2D24G-2L+?

The kit is validated for the ASRock Rack GENOA2D24G-2L+ at DDR5-4800 with 1.1V CL40 2Rx4 registered ECC; mixing different ranks, speeds or voltages can prevent full-capacity recognition, so populate all slots with identical modules per the board's population rules.

How do I verify the kit is running at DDR5-4800 CL40 1.1V with ECC active after installation?

Enter the BIOS or UEFI and confirm the memory reports 4800 MT/s (PC5-38400), CAS latency 40, 1.10 V, registered ECC enabled, and all 768 GB shown across 12 slots.

What exactly ships in the box and is anything else required to install it?

The box contains the 12 x 64 GB DDR5-4800 288-pin ECC registered RDIMM modules (768 GB total); no heat spreaders, cables or tools are included, and the motherboard must support DDR5 RDIMM population.
