Compatible ASUS 2U server memory kit

This 768 GB kit contains six 128 GB DDR5 4800 RDIMM modules built for the ASUS RS720-E11-RS24U dual-socket server. Registered ECC operation with a 4Rx4 organisation and CL40 timing protects data integrity under continuous load. The modules run at 1.1 V and use major OEM DRAM from Samsung, Micron or Hynix.

Suited for capacity-bound workloads

IT teams running virtualisation clusters, in-memory databases or large-scale analytics on the named ASUS platform will benefit from the maximum supported DIMM count. Buyers who need a different form factor, non-ECC memory or speeds above 4800 MT/s should look at other product lines because this kit is validated only for the specified server model.

Verify DIMM slots and BIOS revision

Confirm the RS720-E11-RS24U chassis has six free 288-pin DDR5 slots and that the system BIOS supports 128 GB 4Rx4 registered modules at 4800 MT/s. Check the motherboard manual for population rules and any required firmware update before installing the full kit.

Questions about this item

Will the ASUS RS720-E11-RS24U server accept all six 128GB DDR5 4800 RDIMM modules in this kit?

The kit is built for the ASUS RS720-E11-RS24U 2U dual-socket server and supplies exactly six 288-pin DDR5 4800 ECC registered RDIMMs, matching the platform's memory slot count and electrical requirements.

Can I keep my existing DDR5 4800 ECC registered RDIMMs installed while adding these six 128GB modules?

The RS720-E11-RS24U has a fixed number of DDR5 slots; adding this 6×128GB kit will fill every slot, so any modules already present must be removed before installation.

After installation, how can I confirm the server sees the full 768GB at DDR5 4800 with ECC active?

Check the BIOS memory information screen or run a hardware inventory tool such as dmidecode; it should report 768GB total, DDR5 4800 MT/s, CL40, 1.10V, 4Rx4 organisation and ECC enabled.
