768GB DDR5-6400 ECC RDIMM Kit

This 12-module kit delivers 768GB of DDR5-6400 registered ECC memory built for the Supermicro H13SSL-N motherboard. Each 64GB DIMM operates at 1.1V with CL52 latency and a 2Rx4 organisation. The 288-pin RDIMM form factor matches the board's required registered architecture.

Who this suits and who should look elsewhere

This kit suits administrators upgrading a Supermicro H13SSL-N to its maximum supported capacity with matched modules that populate every slot. Builders needing non-ECC UDIMMs, SODIMMs, lower voltages, or smaller capacities should look elsewhere.

The specification that decides fit

The registered ECC RDIMM design with 2Rx4 ranking and 1.1V operation is the single specification that determines compatibility with the Supermicro H13SSL-N memory controller.

Questions about this item

Does this kit require the Supermicro H13SSL-N motherboard to have 12 DDR5 RDIMM slots to reach 768GB?

Yes, the 768GB kit contains 12 modules of 64GB each, so the board must provide 12 DDR5 288-pin RDIMM slots and support 2Rx4 registered ECC at 1.10V.

Will these DDR5-6400 CL52 RDIMMs run at rated speed when installed in all 12 slots of the H13SSL-N?

The kit is spec-matched to the H13SSL-N memory-population rules, so a fully populated 12-DIMM configuration should operate at DDR5 6400 (PC5-51200) with CL52 latency.

How can I confirm the server recognises all 768GB and ECC is active after installation?

Check the BIOS memory map for 768GB total, verify DDR5-6400 speed and CL52 timings, and confirm ECC status shows enabled or active in the firmware or OS memory report.
