128GB DDR5 ECC RDIMM Kit

This 128GB kit contains two 64GB DDR5 4800 registered ECC RDIMMs built for the Supermicro H13DSG-O-CPU-D motherboard. The 2Rx4 modules operate at 1.1V with CL40 timing and use 288-pin form factor. Registered buffering and on-die ECC protect data integrity in multi-socket server workloads.

Upgrade from UDIMM or lower capacity

Replaces unbuffered UDIMM modules or smaller RDIMM kits that cannot reach full slot population on this platform. The registered architecture allows every DIMM slot to run fully populated at rated speed without overloading the memory controller. The jump is worth it when your workload demands maximum capacity per channel and error correction across all ranks.

DDR5 4800 registered interface limits

DDR5 4800 bandwidth is fixed by the JEDEC base data rate; this kit cannot run faster without motherboard support for higher speeds. Registered DIMMs require a server chipset that implements the RDIMM protocol and will not function in desktop or workstation boards wired for UDIMM. Population rules in the system manual dictate which slots must be filled first for full 128GB operation.

Questions about this item

Will the 288-pin RDIMM modules fit the Supermicro H13DSG-O-CPU-D motherboard DIMM slots?

Yes, the 288-pin Registered DDR5 RDIMM form factor matches the slots required by the Supermicro H13DSG-O-CPU-D motherboard.

What is the correct installation sequence for the 2x64GB kit on this board?

Consult the motherboard manual for the approved DIMM population order; install both modules in the specified slots to run the 128GB kit at DDR5-4800 CL40.

Do these Samsung, Micron or Hynix chips require any firmware updates or periodic maintenance?

No firmware updates or scheduled maintenance are needed; the ECC Registered design corrects single-bit errors automatically during operation.
