128GB DDR5-4800 ECC RDIMM for Supermicro H13DSG

This 128GB registered ECC module runs at DDR5-4800 with CL40 latency and 1.1V operation. It targets administrators upgrading the Supermicro H13DSG-O-CPU-D motherboard where full-capacity population and data integrity are required. The 2Rx4 organisation matches the board's memory-controller expectations exactly.

Replaces partial or mixed-capacity kits

The jump is worth it when the server currently runs fewer than the maximum supported DIMMs or mixes ranks that force the controller to downclock. A matched 2Rx4 registered kit lets every slot run at the rated 4800MT/s without manual timing adjustments and maintains ECC correction across the full 128GB.

Fits 288-pin RDIMM slots on the H13DSG-O-CPU-D

The module needs no heat spreader and draws 1.1V, so it works within the board's standard power budget. It frees the memory controller from driving unbuffered loads, allowing full-slot population while ECC handles single-bit errors transparently. Verify the manual for approved population order before installing.

Questions sur cet article

Will this 288-pin DDR5 RDIMM fit the memory slots on my Supermicro H13DSG-O-CPU-D motherboard?

Yes, the module is a 288-pin registered DDR5 RDIMM built to the exact form factor that the Supermicro H13DSG-O-CPU-D requires; it is not a UDIMM or SODIMM and will seat correctly in the board's DDR5 slots.

What is the correct installation sequence for populating all slots with these 2Rx4 registered ECC modules?

Install the RDIMMs in the order specified by the Supermicro H13DSG-O-CPU-D manual, typically filling the primary channel slots first; the registered buffer allows full-speed operation when every slot is populated, but skipping the prescribed sequence can prevent the system from posting.

How do I know when a 128GB 2Rx4 ECC RDIMM needs replacement in a production server?

Monitor the system logs for corrected ECC events; a rising count of single-bit corrections or any uncorrectable multi-bit error reported by the BMC or OS indicates the module should be swapped before it causes downtime.
