ASUS RS720Q-E11-IM DDR5 ECC RDIMM

This 16GB DDR5 module is built for the ASUS RS720Q-E11-IM 2U4N high density immersion cooling server. It delivers registered ECC memory for enterprise workloads that demand data integrity and stable operation under continuous load. The single rank 1Rx8 organisation suits dense configurations where every slot counts. IT teams upgrading these specific platforms gain a validated memory option.

288 pin registered DDR5 build

The module uses a 288 pin DDR5 RDIMM form factor without a heat spreader, relying on the server's direct immersion cooling loop for thermal management. Registered buffering reduces electrical load on the memory controller, helping signal quality across fully populated channels. ECC circuitry corrects single bit errors to protect critical datasets. The 1.10V operating voltage matches the platform's DDR5 power envelope.

Check DDR5 slot count and population rules

Verify the RS720Q-E11-IM motherboard has free DDR5 RDIMM slots and confirm the maximum supported capacity per channel before ordering. Ensure the BIOS revision recognises DDR5 4800 CL40 registered modules at 1Rx8 density. Mixing ranks or speeds can disable ECC or downclock the entire array, so plan the full memory layout in advance.
