768GB DDR5 4800 ECC RDIMM kit

This 768GB kit contains twelve 64GB DDR5 4800 registered DIMMs with ECC and CL40 latency. It is built for the ASUS RS700A-E12-RS4U 1U dual-processor server and runs at 1.10V. The modules use 2Rx4 organisation and 288-pin DDR5 form factor.

Suitability and limits

This memory suits administrators who need maximum registered ECC capacity in the supported ASUS 1U platform. It does not suit builds that require unbuffered DIMMs, lower voltages, or consumer motherboards without registered DIMM support. Buyers needing smaller capacities or different speeds should look elsewhere.

Deciding specification

The kit provides 768GB total capacity across twelve 64GB registered ECC modules at DDR5 4800. This capacity and registration type determine whether the server can accept the upgrade.

Questions about this item

How can I verify the 768GB kit is running at DDR5 4800 CL40 after installation?

Check the BIOS memory information or a system tool such as CPU-Z; it should show 12 modules at 4800 MT/s with CAS latency 40 and 1.10 V.

What comes in the box and do I need anything else for the ASUS RS700A-E12-RS4U server?

The package contains 12 × 64 GB DDR5 288-pin ECC RDIMMs; no extra parts are required for the compatible ASUS 1U dual-processor server.

Why choose the 768GB 12 × 64 GB configuration over a smaller kit?

This kit fills all 12 slots with 2Rx4 registered modules, delivering the maximum supported capacity for the ASUS RS700A-E12-RS4U platform.
