System-Specific DDR5 RDIMM Kit

This 1.5TB kit contains twelve 128GB registered ECC modules built for the Supermicro H13SSL-NT motherboard. It targets administrators who need maximum supported capacity on that platform without mixing module sizes.

Registered ECC Architecture at 4800 MT/s

Registered buffering lets every slot run fully populated at the rated 4800 MT/s while ECC corrects single-bit errors in flight. The 2Rx4 organisation and 1.1V operation match the board's memory controller expectations so the full 1.5TB is recognised at speed.

288-Pin DDR5 RDIMM Form Factor

The modules use the 288-pin DDR5 RDIMM form factor required by the H13SSL-NT; UDIMM or SODIMM variants will not fit. Verify the motherboard's population rules and supported capacity limits in the system manual before installation.

Questions about this item

Will this 12-module DDR5-4800 RDIMM kit run at full speed on a Supermicro H13SSL-NT with older DDR5-4800 DIMMs still installed?

The board runs all slots at the speed of the slowest DIMM. If the older modules are also DDR5-4800 CL40 1.1V 2Rx4 RDIMMs the kit will operate at its rated 4800 MT/s; otherwise every module drops to the lower common speed.

How can I confirm the Supermicro H13SSL-NT sees all 1.5TB and that ECC is active after installing the 12x128GB kit?

Enter BIOS and check the memory information page — it should list 1.5TB total across 12 slots at 4800 MT/s with ECC enabled; the OS command `dmidecode -t memory` or Windows `wmic memorychip` will also show 128GB per slot, Registered type, and ECC capability.

Does the box contain only the twelve 128GB RDIMMs or are any cables, brackets or cooling parts included?

The package content lists only the 1.5TB 12x128GB DDR5-4800 PC5-38400 2Rx4 1.1V CL40 288-pin ECC RDIMM kit — no cables, brackets, heatsinks or other accessories are supplied.
