Compatible ASUS RS720Q-E11-IM memory kit

This 256GB kit contains sixteen 16GB DDR5 4800 RDIMM modules built for the ASUS RS720Q-E11-IM server. Registered ECC design with CL40 latency and 1.10V operation targets enterprise workloads requiring data integrity and high density.

Verify DDR5 RDIMM slot count and population rules

Confirm the motherboard provides sixteen 288-pin DDR5 slots and supports 1Rx8 registered ECC modules at 4800 MT/s. Check the system manual for maximum capacity per channel and required slot-filling order before installing all sixteen modules.

Fills all memory channels for maximum throughput

The sixteen-module kit populates every available slot, delivering the full 256GB capacity the platform allows. Registered buffering reduces electrical load on the memory controller, freeing signal margin for stable operation under sustained server loads.

Questions about this item

Does the 256GB kit ship as 16 separate 16GB modules or must I order them individually?

The package contains 16 modules of 16GB each, giving a total of 256GB in a single kit.

How do I decide between the CL40 4800MT/s kit and a faster or lower-latency alternative?

This kit is validated for the ASUS RS720Q-E11-IM at DDR5 4800 CL40 1.10V; choose it when the server requires that exact speed, latency and voltage combination.

What does the 4800MT/s rating deliver once the modules are installed in the RS720Q-E11-IM?

The memory runs at DDR5 4800 (PC5-38400) with CL40 timing, providing the rated bandwidth and error-corrected registered operation the server expects.
