128GB DDR5-6400 ECC RDIMM for Supermicro H13SSW

This 128GB DDR5-6400 registered ECC module is built for the Supermicro H13SSW motherboard. It delivers the exact rank, voltage and timing the board's memory controller expects so the full capacity is recognised at rated speed. The 2Rx4 organisation and 1.1V operation match the platform's qualified specifications.

288-pin registered form factor with major OEM DRAM

The 288-pin RDIMM form factor fits only registered DIMM slots; it will not work in UDIMM or SODIMM sockets. Registered buffering offloads the memory controller, allowing every populated slot to run at full capacity. ECC corrects single-bit errors on the fly to prevent silent data corruption. Chips are sourced from Samsung, Micron or Hynix.

Replaces lower-capacity or slower DDR5 RDIMMs

Upgrading from smaller or lower-speed registered ECC modules adds capacity and bandwidth for memory-bound server workloads. The jump is worth it when your application hits capacity limits or needs the 6400 MT/s data rate. Verify your system manual for supported populations and maximum capacity per slot before purchasing.

Questions about this item

Does the DDR5 6400 PC5-51200 interface cap at CL52 on this module?

Yes, the module is rated CL52 at DDR5 6400 (PC5-51200) and the registered ECC design keeps every slot stable at that timing when fully populated.

What physical slot and form factor does the 288-pin RDIMM require?

It fits a standard 288-pin DDR5 RDIMM slot on the Supermicro H13SSW motherboard; UDIMM or SODIMM slots will not accept it.

How is the 2Rx4 registered kit installed and what step is often missed?

Insert the RDIMM into the correct population-order slot per the H13SSW manual, press until the ejectors lock, then verify the BIOS recognises the full 128 GB at 6400 MT/s.
