768GB DDR5 ECC RDIMM kit

This 768GB memory kit contains twelve 64GB DDR5 registered DIMMs rated at 4800MT/s with CL40 latency. Each module operates at 1.1V and uses a 2Rx4 organisation on a 288-pin form factor. The kit is built for the ASUS RS720Q-E11-IM immersion-cooled server platform.

Suited for RS720Q-E11-IM density upgrades

This kit targets administrators expanding the ASUS RS720Q-E11-IM to its maximum supported memory capacity with validated ECC registered modules. Buyers needing non-ECC memory, lower capacities, different form factors or compatibility with other server platforms should look elsewhere.

12x64GB 2Rx4 registered configuration

The decisive specification is the twelve-module 2Rx4 registered layout delivering 768GB total capacity. This exact population matches the RS720Q-E11-IM memory architecture and determines whether the kit fits the platform's slot count and rank requirements.

Questions about this item

Does the ASUS RS720Q-E11-IM need a specific CPU or chipset revision before these DDR5 4800 CL40 2Rx4 modules will initialise?

The kit is validated for the ASUS RS720Q-E11-IM platform; any processor and chipset combination officially supported by that server will recognise the 12 x 64 GB DDR5 4800 CL40 2Rx4 registered ECC DIMMs.

Can I keep older DDR5 4800 ECC RDIMMs of a different rank or capacity in the same chassis while adding this 768 GB kit?

Mixing ranks or capacities is possible only if the ASUS RS720Q-E11-IM memory population rules allow it; the server’s manual defines which slot groups must match, so follow that guide when combining this 2Rx4 kit with existing modules.

After installing all 12 modules, what BIOS indication confirms they are running at DDR5 4800 CL40 with ECC active?

Enter the ASUS RS720Q-E11-IM BIOS and check the memory information screen — it should show 768 GB total, 4800 MT/s data rate, CL40 latency, registered ECC status and 1.1 V operating voltage.
