64 GB DDR5 ECC RDIMM for ASUS RS720Q-E11-IM

This 64 GB DDR5 module is built for the ASUS RS720Q-E11-IM immersion-cooled server. It delivers registered ECC memory for mission-critical workloads in high-density 2U4N configurations. The single DIMM simplifies capacity scaling in validated platforms.

Registered ECC with CL40 latency at 4800 MT/s

The module runs at DDR5 4800 (PC5-38400) with a CAS latency of CL40 and operates at 1.10 V. Registered buffering and on-die ECC protect data integrity under sustained load. The 2Rx4 organisation fits the server's memory architecture without adaptation.

Single-module kit with lifetime replacement coverage

The package contains one 288-pin RDIMM rated for 64 GB. No heat spreader is included, relying on the chassis immersion loop for thermal management. A lifetime replacement warranty backs the validated compatibility.

Questions about this item

What does the 4800 MT/s speed mean for my ASUS RS720Q-E11-IM server?

The module runs at DDR5 4800 MT/s (PC5-38400), delivering the maximum JEDEC-standard data rate supported by the platform's memory controller.

How does the registered ECC design affect the memory bus?

The registered buffer places one clock cycle between the DRAM and the memory controller, reducing electrical load so the RS720Q-E11-IM can populate more slots per channel while ECC corrects single-bit errors.

Will this 288-pin RDIMM fit the immersion-cooled 2U4N chassis?

Yes — it is a standard-height 288-pin DDR5 RDIMM with no heat spreader, so it clears the tight clearances of the ASUS RS720Q-E11-IM immersion-cooling trays.
