System-Specific DDR5 Server Memory

This NEMIX RAM kit provides 512 GB across eight 64 GB DDR5 4800 RDIMM modules. It is built for the ASUS RS720Q-E11-IM high-density immersion-cooling server. ECC and registered buffering protect data integrity in mission-critical workloads.

Thermals and Power

Each module operates at 1.10 V without a heat spreader, relying on the chassis immersion loop for cooling. Registered signalling and 2Rx4 organisation keep electrical load predictable under sustained server duty. No fan noise is generated by the memory itself.

Capacity and Compatibility

The 512 GB total capacity fills eight DDR5 slots with CL40 timing at 4800 MT/s. Buyers needing a different capacity per module, a non-ECC configuration or a motherboard outside the qualified ASUS platform cannot use this kit.

Questions about this item

How do I install the 288-pin DDR5 RDIMM modules in the ASUS RS720Q-E11-IM, and what step is often missed?

Power down the server, open the 2U4N chassis, align each 64 GB module with the keyed 288-pin slot, press firmly until the ejector clips lock, then verify all eight modules are recognised in BIOS before closing the cover.

What maintenance or replacement will the 512 GB DDR5 4800 ECC RDIMM kit need over time?

The modules have no heat spreader and no moving parts, so no routine maintenance is required; if a DIMM fails, the lifetime replacement warranty covers a direct swap of the faulty 64 GB stick.

What limit appears first when the 8x64 GB DDR5 4800 CL40 kit runs sustained workloads in the RS720Q-E11-IM?

The registered ECC design and 1.10 V operation keep thermals stable, so the first ceiling is the DDR5 4800 MT/s bandwidth and CL40 latency ceiling rather than thermal throttling.
