128GB DDR5 ECC RDIMM for Supermicro H13DSG-O-CPU

This 128GB DDR5 5600MHz registered ECC module is built for the Supermicro H13DSG-O-CPU motherboard. It delivers the exact 2Rx4 rank structure, 1.1V operation and CL46 timing the platform expects. Enterprise servers running memory-intensive workloads gain full-capacity recognition at rated speed without manual tuning.

Replaces mismatched or lower-capacity DDR5 RDIMMs

The jump is worth it when current DIMMs do not match the board's required registered architecture, voltage or rank configuration. Population rules on this platform demand precise spec alignment; using unvalidated modules can prevent boot or limit usable capacity across all slots.

Limited to DDR5 288-pin registered ECC interface

This standard requires a motherboard with DDR5 RDIMM slots and registered memory support; it will not fit UDIMM or SODIMM sockets. Bandwidth and latency are fixed at DDR5 5600 PC5-44800; the memory controller cannot exceed this data rate regardless of processor capability.

Questions about this item

Does the 288-pin DDR5 RDIMM fit the Supermicro H13DSG-O-CPU motherboard slots?

Yes, the module is a 288-pin DDR5 RDIMM, the exact form factor the H13DSG-O-CPU requires; it is not a UDIMM or SODIMM.

What installation step is often missed when populating all slots with these 2Rx4 registered DIMMs?

Follow the motherboard manual's specific population order; registered DIMMs must be installed in the approved sequence for full 128 GB recognition at 5600 MHz.

When should the 1.1 V DDR5 ECC RDIMM be replaced in a production server?

Replace the module if ECC logs show rising correctable error counts or if the system reports uncorrectable errors, indicating chip degradation.
