Server-grade DDR5 memory kit

This NEMIX RAM kit delivers 768GB of DDR5 4800 registered ECC memory across twelve 64GB modules. It is built for the ASUS RS700-E11-RS12U 1U dual-socket server where maximum capacity and error correction are required. The 2Rx4 organisation and 1.10V operation match the platform's qualified configuration.

Thermals noise and power

Registered DDR5 modules run at 1.10V, keeping power draw low inside a dense 1U chassis. No heat spreaders are fitted, so airflow from the server's high-RPM fans moves directly over the DRAM. The CL40 latency at 4800 MT/s is the standard JEDEC timing for this density and voltage.

What the kit changes

Populating all twelve slots with qualified 64GB RDIMMs lets the ASUS RS700-E11-RS12U reach its 768GB maximum without mixing capacities or ranks. ECC and register circuitry protect data integrity for virtualisation, database and HPC workloads. The single part number MR38400-924K12 simplifies ordering and eliminates slot-by-slot compatibility checks.

Questions about this item

How do I install the 12 DDR5 RDIMM modules into the ASUS RS700-E11-RS12U server and which population rule is often missed?

Power down the server, open the chassis, and seat each 64 GB 288-pin RDIMM firmly until the ejector clips lock; the step most people miss is following the exact slot order in the ASUS manual so the 12 modules populate all channels evenly for the registered signal to train at 4800 MT/s.

What maintenance or replacement will this 768 GB DDR5 ECC kit need during its service life?

The modules have no heat spreaders and no moving parts, so the only upkeep is keeping the server's air filters clean and fans functional; if a single 64 GB RDIMM ever fails, the lifetime replacement warranty covers swapping that module without returning the full 12-piece kit.

What is the first limit that appears when this registered DDR5 4800 CL40 memory runs sustained workloads on the RS700-E11-RS12U?

The registered buffer and CL40 latency set the throughput ceiling; under continuous load the memory controller hits its maximum sustainable bandwidth at 4800 MT/s before any thermal throttle can occur on the bare DRAM packages.
