128 GB DDR5-4800 ECC RDIMM

This single 128 GB registered DDR5 module runs at 4800 MT/s with CL40 latency and 1.1 V operation. It is built for ASUS RS720Q-E11-IM high-density immersion-cooling servers that require 288-pin ECC RDIMM memory. The 4Rx4 organisation and Samsung, Micron or Hynix chips target maximum capacity per slot in enterprise chassis.

Suited for memory-bound server workloads

IT teams expanding ASUS 2U4N platforms with dense, error-correcting memory will match the qualified part number MR38400-744K1. Builders needing unbuffered UDIMMs, non-ECC modules, lower capacities per DIMM or consumer motherboard compatibility should select a different product line.

Sustained load behaviour in immersion cooling

Registered buffering and on-die ECC maintain data integrity during continuous multi-threaded compute across all ranks. The 1.1 V DDR5 baseline keeps power draw predictable inside the sealed coolant loop, while the 4Rx4 density reduces the number of active modules required for 720 GB-plus system configurations.

Questions about this item

Will this 128GB DDR5 4800 module install in my ASUS RS720Q-E11-IM server?

Yes, the module is validated for the ASUS RS720Q-E11-IM immersion-cooling server and uses the 288-pin DDR5 RDIMM form factor required by that platform.

Can I mix this 4Rx4 ECC RDIMM with lower-rank DDR5 modules already in the system?

The server's memory controller supports mixed-rank populations; follow the ASUS RS720Q-E11-IM population rules for 4Rx4 modules to maintain stability.

How do I confirm the module runs at 4800 MT/s with CL40 latency after installation?

Check the BIOS memory information or OS tools such as dmidecode; they should report DDR5 4800 (PC5-38400) speed and CAS latency 40.
