64GB DDR5 ECC RDIMM kit

This kit supplies 64GB across four 16GB DDR5 4800 RDIMM modules. Each module is registered and provides ECC error correction for data integrity. The memory runs at 1.1V with CL40 latency and uses a 288-pin form factor. It is validated for the ASUS RS700-E11-RS4U dual-socket 1U server platform.

Who this suits and who should look elsewhere

This kit suits administrators upgrading or populating the ASUS RS700-E11-RS4U server with registered ECC memory. Builders needing unbuffered UDIMMs, non-ECC modules, or a different DDR generation cannot use this kit. Systems that require higher frequencies, lower latencies, or larger per-module capacities should consider other configurations.

DDR5 4800 registered ECC specification

The decisive specification is DDR5 4800 registered ECC RDIMM with CL40 timing at 1.1V. The server memory controller and motherboard firmware must support this exact combination of speed, registration, error correction and voltage for the kit to function correctly.

Questions about this item

My ASUS RS700-E11-RS4U server has four DIMM slots — will this 64 GB kit fill them all?

Yes, the kit contains four 16 GB modules for a total of 64 GB, matching the four-slot layout of the RS700-E11-RS4U.

Can I add these 1Rx8 CL40 DDR5 4800 modules to existing DDR5 RDIMMs already installed in the server?

Mixing ranks or speeds is not recommended; for stable operation populate all four channels with identical 1Rx8 CL40 DDR5 4800 modules.

After installing the kit, how can I confirm the memory is running at DDR5 4800 with ECC active?

Check the BIOS memory information screen — it should show 64 GB total, 4800 MT/s, CL40 timings and ECC enabled.
