256GB DDR5 ECC RDIMM kit

This 256GB kit comprises four 64GB DDR5 4800 registered DIMMs with ECC and CL40 latency. It is built for the ASUS RS720Q-E11-IM 2U4N high-density immersion-cooling server. The modules run at 1.1V and use a 2Rx4 organisation on 288-pin DDR5 RDIMM form factor.

Sustained-load behaviour

Registered buffering and on-die ECC correct single-bit errors in real time while the memory controller manages heavy, continuous workloads across all four nodes. The 1.1V operating voltage keeps power draw predictable during long compute runs in the immersion chassis.

Deciding specification

The kit is validated only for the ASUS RS720Q-E11-IM platform; it will not function in consumer motherboards, workstations requiring unbuffered UDIMMs, or servers that demand a different registered DDR5 profile.

Questions about this item

Will the four 64 GB DDR5 4800 CL40 RDIMMs run hot or draw much power when the server operates continuously?

The kit runs at 1.1 V with no heat spreaders; DDR5 4800 modules at this voltage typically stay cool under sustained load, and the registered design helps keep power draw predictable.

What must the server already have so these 288-pin DDR5 RDIMMs can be installed and recognised?

The ASUS RS720Q-E11-IM motherboard with DDR5 RDIMM slots and a BIOS that supports 2Rx4 registered ECC modules at 4800 MT/s is required.

Can the 2Rx4 DDR5 4800 RDIMMs share memory channels with other DDR5 RDIMMs of different capacity or rank already in the system?

Yes, provided the other modules are also DDR5 registered ECC and the motherboard's memory controller supports mixed-capacity 2Rx4 populations at 4800 MT/s.
