Target Use

This 32 GB DDR5 module is built for Supermicro servers that require registered ECC memory. The single-rank 1Rx4 layout and 288-pin RDIMM form factor suit platforms validated for the MEM-DR532MA-ER48 part number.

Sustained Load Behaviour

Operating at 4800 MT/s with CL40 timing and 1.10 V, the module maintains rated throughput during continuous workloads. Native DDR5 ECC corrects single-bit errors on the fly, preserving data integrity without halting the system.

Upgrade Context

It replaces unregistered or non-ECC DIMMs when the platform demands registered error-correcting memory. The jump is justified when the server firmware or vendor qualification list explicitly calls for this Supermicro-certified part.

Questions about this item

How much power does the 1.10V DDR5 module draw under sustained server workloads?

It operates at the standard DDR5 voltage of 1.10V; actual power draw depends on your platform's memory controller and load profile.

What motherboard slot and chipset support are required for this 288-pin RDIMM?

You need a server motherboard with DDR5 RDIMM slots and a chipset that supports registered ECC memory at 4800 MT/s.

Can this CL40 4800 MT/s module run in a system that currently uses slower DDR5 memory?

Yes, it will downclock to match the slowest installed module while maintaining registered ECC operation.
