48 GB DDR5 RDIMM for servers

This 48 GB DDR5-5600 registered DIMM is built for enterprise servers that require ECC protection and registered signalling. The single-rank 1Rx4 layout keeps electrical loading low on dense memory channels. It operates at 1.10 V and uses a standard 288-pin form factor.

Sustained-load behaviour

On-die ECC and x80 ECC with two independent I/O sub-channels correct errors continuously during long-running workloads. Hard and soft post-package repair plus sideband access via I3C/I2C maintain data integrity over extended periods. The 32 internal banks help sustain throughput when multiple threads access memory simultaneously.

Single-rank 1Rx4 organisation

The 1Rx4 rank structure is the specification that determines whether this module fits your server's memory population rules. Systems limited to one rank per channel or requiring x4 device width need this exact organisation; dual-rank or x8 modules will not satisfy the same constraint.

Questions about this item

How much power does the 1.10 V DDR5 5600 RDIMM draw when running continuously?

The module operates at a typical VDD and VDDQ of 1.10 V with VPP at 1.8 V, so sustained power draw is determined by the 1.10 V rail and the 5600 MT/s data rate.

What motherboard slot and memory controller features are required for this 288-pin DDR5 5600 RDIMM?

A DDR5-compatible server motherboard with a 288-pin RDIMM slot and a memory controller that supports registered DDR5 at 5600 MT/s, 1.10 V VDD/VDDQ and on-die ECC is required.

Can this 48 GB 1Rx4 DDR5 5600 RDIMM be mixed with older DDR5 registered modules of different capacities or ranks?

Mixing is possible only if the platform's memory controller supports mixed-capacity and mixed-rank DDR5 RDIMM populations at 5600 MT/s with CL46 timing and 1.10 V operation.
