  • 128 GB total capacity with two 64 GB modules
  • DDR5 4800 MT/s speed rated at PC5-38400 bandwidth
  • ECC registered RDIMM for server data integrity
  • CL40 CAS latency at 1.1 V operating voltage
  • 2Rx4 dual-rank 288-pin layout for ASUS RS720Q-E11-IM compatibility

Purpose-built server memory

This 128 GB kit delivers 2 × 64 GB DDR5 ECC RDIMM modules tuned for ASUS RS720Q-E11-IM immersion-cooled servers. Registered buffering and on-die error correction keep data integrity intact under sustained enterprise workloads.

Capacity and headroom

Two dual-rank 2Rx4 modules provide 128 GB at 4800 MT/s CL40. The configuration suits memory-heavy virtualization and database tiers; systems needing more than 128 GB per channel or lower latency bins will require different modules.

Build integration

Modules slot into 288-pin DDR5 RDIMM sockets and run at 1.1 V without a heat spreader. The registered design demands a compatible server chipset and BIOS; desktop or unbuffered platforms cannot use this kit.

Questions about this item

Will these DDR5 4800 CL40 modules run at rated speed with existing DDR5 4800 memory in the ASUS RS720Q-E11-IM?

Yes, both kits share DDR5 4800 PC5-38400 speed and CL40 latency, so the memory controller will keep the same timing across all populated slots.

How can I verify the ECC RDIMM kit is operating correctly after installation?

Enter the ASUS BIOS and confirm 128 GB total, DDR5 4800 MT/s, 1.10 V, registered mode and ECC enabled for each 64 GB module.

What ships in the box and what must I source separately?

The box contains the 2 x 64 GB DDR5 4800 CL40 1.10 V ECC RDIMM modules only; no heat spreaders, cables or tools are included.
