48 GB DDR5-5600 Registered ECC Module

This 48 GB DDR5 RDIMM runs at 5600 MHz with CL46 latency and 1.10 V operation. It is built for servers and workstations that require registered, error-correcting memory. The dual-rank 2Rx8 organisation and on-die ECC help maintain data integrity under sustained loads.

Replacing slower or non-ECC DDR5 DIMMs

The jump is worth it when your platform supports DDR5-5600 registered memory and you need the 48 GB capacity per module to reach higher total system memory. If your board only accepts unbuffered UDIMMs or a lower speed grade, this module will not be compatible.

Fits 288-pin DDR5 RDIMM slots without a heat

The low-profile PCB height of 1.23 inches (31.25 mm) eases clearance in dense chassis. It requires a motherboard with registered DDR5 support and a memory controller that can address 2Rx8 modules. No additional cooling hardware is included, so airflow across the modules must be provided by the system.

Questions about this item

Will the 1.23 inch module height clear my server's DIMM slot spacing?

The PCB height is 1.23 inches (31.25 mm), matching the standard DDR5 RDIMM form factor so it fits any 288-pin registered DIMM slot.

What is the correct alignment step when seating this 288-pin DDR5 RDIMM?

Align the single offset notch on the gold edge connector with the key in the slot, press straight down until both retention clips click — do not angle the module.

When should I consider replacing this 48 GB DDR5-5600 module?

Replace it if the system logs uncorrectable ECC errors, fails memory training at 5600 MT/s, or shows physical damage to the 288-pin edge connector.
