96GB DDR5-6400 ECC Registered DIMM

This single 96GB DDR5 module runs at 6400MHz with CL52 timings and 1.10V voltage. It uses a 288-pin RDIMM form factor with registered signal processing and on-die ECC. The dual-rank design delivers high capacity for memory-intensive server workloads.

Suited for servers needing maximum density per slot

Ideal for database servers, virtualization hosts and workstations that require registered ECC memory at scale. Not suited for desktop boards that only accept unbuffered UDIMMs, nor for systems limited to lower DDR5 speeds or smaller maximum module capacities.

Verify platform support for 96GB RDIMMs

Confirm the motherboard and CPU memory controller support 288-pin DDR5 RDIMMs at this capacity and speed. Check qualified vendor lists for 6400MHz operation and ensure the BIOS version enables registered ECC modes. Mixing with different speeds, ranks or unbuffered modules is not supported.

Questions about this item

Will the 288-pin DDR5 RDIMM fit my server motherboard that uses DDR5 slots?

The module uses the standard 288-pin DDR5 RDIMM form factor, so it fits any server board with DDR5 DIMM slots that support registered ECC memory.

Can I run this CL52 registered ECC module together with older DDR5 RDIMMs that have lower latency?

The system will operate all installed modules at the speed and timings of the slowest kit, so mixing CL52 with tighter-timing DDR5 RDIMMs forces the faster sticks to run at CL52.

How do I confirm the 96 GB module is running at 6400 MHz with ECC active after installation?

Check the BIOS memory information screen or run a tool such as dmidecode; it should report 6400 MT/s, CL52 timings, 1.10 V and ECC type as registered.
