128GB DDR5 ECC RDIMM for Supermicro Workstations

This single-module upgrade delivers 128GB of registered DDR5 memory at 4800MHz with CL40 latency. It operates at 1.1V and uses a 4Rx4 organization with ECC error correction. The 288-pin RDIMM is validated for the Supermicro SuperWorkstation SYS-751A-I and X13DAI-T platforms.

Suited for registered DDR5 servers.

IT professionals expanding Supermicro workstation capacity for virtualization or database workloads will find this module compatible. Builders using consumer motherboards, laptops, or systems requiring unbuffered UDIMM memory cannot use this registered ECC RDIMM.

Registered ECC RDIMM form factor decides fit

The module is a 288-pin DDR5 RDIMM with registered buffering and ECC. Only systems designed for registered DDR5 RDIMMs at 4800MHz can accept it; unbuffered or non-ECC platforms will not support this part.

Questions about this item

Does the 1.10 V DDR5 module add noticeable heat or fan noise when the SuperMicro SYS-751A-I runs continuously?

The module operates at the standard DDR5 voltage of 1.10 V and has no heat spreader, so thermal output matches typical registered DIMM expectations for this platform.

What must the SuperMicro X13DAI-T motherboard already provide for this 288-pin 4Rx4 RDIMM to function?

The board needs DDR5 RDIMM slots that support 4800 MT/s, ECC, registered operation and 4Rx4 organisation; the module simply plugs into those slots.

Will this CL40 4800 MT/s stick run stably alongside any existing DDR5 RDIMMs already installed in the workstation?

Yes, provided the other modules are also DDR5 ECC RDIMMs rated for 4800 MT/s; the system will operate at the lowest common speed and latency.
