Purpose-built server memory

This 64GB kit delivers two 32GB DDR5 RDIMMs rated at 4800MHz PC5-38400 with CL40 latency and 1.1V operation. Registered ECC architecture and 1Rx4 organisation match the exact electrical requirements of the ASRock Rack GENOA2D24G-2L+ motherboard so the memory controller recognises full capacity at rated speed without manual tuning.

Thermals and power profile

Modules run at the standard DDR5 1.1V without heat spreaders, relying on server chassis airflow for cooling. Registered buffering reduces electrical load on the memory controller, keeping per-slot power draw low and acoustic impact negligible in typical rack environments.

Sustained-load behaviour

ECC corrects single-bit errors on the fly during continuous operation, preventing silent data corruption that can accumulate over long compute runs. Registered signalling maintains signal integrity across fully populated channels so bandwidth and latency remain stable through extended workloads rather than throttling after a short burst.

Questions about this item

How do I install the 288-pin RDIMM kit on the ASRock Rack GENOA2D24G-2L+ and what step is often missed?

Power down the server, open the chassis, and seat both 32 GB modules in the exact slot order shown in the motherboard manual; the step most people miss is confirming the population sequence for 1Rx4 registered DIMMs before powering on.

What maintenance or replacement will the 64 GB DDR5 ECC RDIMM kit need over its service life?

No routine maintenance is required; the modules have no heat spreaders to clean and ECC corrects single-bit errors automatically, so replacement is only needed if a DIMM fails or capacity must be increased beyond 64 GB.

What limit appears first when the 4800 MHz CL40 1.1 V registered memory runs sustained workloads?

The registered buffer and CL40 latency set the throughput ceiling, so sustained bandwidth tops out at the DDR5-4800 rating before thermal or voltage headroom becomes a factor.
