System-specific DDR5 kit

This 1 TB kit contains eight 128 GB DDR5 4800 CL40 registered ECC RDIMMs built for the ASUS RS520A-E12-RS24U single-socket 2U server. It targets administrators who need maximum registered capacity in that exact platform.

1.1 V registered operation

Each module runs at 1.10 V with a 4Rx4 organisation, so the registered buffer absorbs electrical load instead of the CPU memory controller. The kit has no heat spreaders, relying on the server’s directed airflow to keep temperatures in check.

Eight-module population

Populating all twelve DIMM slots with this 8×128 GB kit delivers the full 1 TB capacity the motherboard supports. Buyers who need more than twelve modules or non-registered DIMMs must choose a different platform.

Въпроси за този артикул

How do I install these 288-pin DDR5 RDIMM modules into the RS520A-E12-RS24U server?

Power down the server and open the chassis. Align each module's notch with the slot key and press firmly until both latches click. Follow the motherboard manual for the correct population order across the 12 or 24 slots.

What maintenance or replacement will the 1.1V ECC registered DIMMs need over time?

ECC corrects single-bit errors on the fly. If a module develops uncorrectable faults the system will log the event; replace the affected 128GB stick. No periodic maintenance is required beyond keeping airflow clear.

At what point does the CL40 4800 MT/s bandwidth limit appear under sustained load?

The 4Rx4 organisation and PC5-38400 rating set the peak throughput. Under continuous heavy traffic the memory controller hits this bandwidth ceiling before latency becomes the bottleneck.
