Server Memory Upgrade

This 256GB kit supplies eight 32GB DDR5 4800 CL40 ECC registered DIMMs built for the ASUS RS720-E11-RS12U dual-socket server. Each module runs at 1.10V with a 1Rx4 organisation using major OEM chips. The registered design adds a buffer that stabilises heavy multi-threaded workloads in virtualisation, database and compute clusters.

Thermals and Power

Operating at the standard 1.10V DDR5 voltage, the modules draw minimal power per stick while delivering PC5-38400 bandwidth across all eight slots. No heat spreaders are fitted, so airflow through the 2U chassis handles cooling without added acoustic load. The registered architecture keeps signal integrity high under sustained load, reducing correctable errors that would otherwise trigger retries.

Compatibility Assurance

The kit is validated for the specific ASUS RS720-E11-RS12U platform, removing guesswork from population rules and BIOS revision requirements. NEMIX RAM stress-tests every module under load before shipment, targeting the stability demanded by mission-critical deployments. Lifetime replacement coverage and US-based technical support back the installation, though buyers needing non-ASUS platforms or consumer motherboards should look elsewhere.

Questions sur cet article

How do I install the 8x32GB DDR5 4800 RDIMMs in the RS720-E11-RS12U server?

Power down the ASUS RS720-E11-RS12U, open the chassis, locate the 288-pin DDR5 slots, align each 1Rx4 module notch, press firmly until the ejector clips lock, populate all eight slots for 256GB total, then close the case and power on.

What maintenance or replacement will the DDR5 4800 ECC RDIMM kit need later?

The modules have no heat spreaders and run at 1.10V; keep server airflow clean, monitor ECC corrected-error counters in the OS, and replace any stick that logs uncorrectable errors — otherwise no scheduled maintenance is required.

What limit appears first under sustained load with this 256GB DDR5 4800 CL40 kit?

At 4800 MT/s and CL40 latency, the memory controller bandwidth ceiling is reached before thermal throttling on these bare 1Rx4 RDIMMs, so sustained throughput tops out at the rated PC5-38400 data rate.
