96GB DDR5-5600 RDIMM for servers

This 96GB DDR5-5600 CL46 ECC Registered RDIMM uses Micron components in a 2Rx4 layout. It runs at 5600 MHz with 46-45-45 timings at 1.10V on a 288-pin interface. The module targets enterprise servers and workstations that require high-capacity, error-correcting memory for virtualisation, databases or compute clusters.

Suited for registered-DIMM platforms needing

Buyers whose systems accept only unbuffered UDIMMs cannot use this module. Builds limited to lower single-module capacities should look at smaller RDIMMs. Workstations without ECC support in the CPU or chipset will not benefit from the error-correction feature.

Straightforward 288-pin installation

Align the key notch with the slot and press until the latches click; no heat spreader means tight clearance is rarely an issue. Common problems include mixing registered and unbuffered DIMMs, populating slots in the wrong order for the memory controller, or running the module on a board that does not support DDR5-5600 registered operation.

Questions about this item

My motherboard has DDR5 slots — will this 288-pin RDIMM fit and run at 5600 MHz?

The module is a 288-pin DDR5 RDIMM rated for DDR5-5600 (PC5-44800) at 1.10 V. It requires a DDR5-compatible motherboard with registered-DIMM support and ECC enabled in the BIOS.

If I keep my existing DDR5-4800 RDIMMs, can I add this 96 GB module alongside them?

Mixing speeds will force all modules to run at the lowest common speed and timing; the 5600 MHz module will downclock to match 4800 MHz, and registered/ECC settings must be identical across every slot.

After installing, how do I confirm the module is running at CL46 46-45-45 timings?

Check the BIOS memory-info screen or a tool such as CPU-Z: it should show DDR5-5600, CAS 46, timings 46-45-45, voltage 1.10 V, ECC active and registered mode enabled.
