Exact-match DDR5-4800 kit for Supermicro H13SSL-NT

This 64GB kit contains four 16GB DDR5-4800 registered ECC RDIMMs built to the precise rank, voltage and timing the H13SSL-NT memory controller expects. Each module runs at 1.1V with CL40 latency and a 1Rx8 organisation so the server recognises the full capacity at rated speed. It is intended for administrators upgrading or populating that specific motherboard.

Registered architecture

The registered design buffers the address and command signals, letting every slot operate fully populated without overloading the memory controller. ECC circuitry detects and corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots in production workloads. Modules use a standard 288-pin RDIMM connector and have no heat spreader, matching the board's physical requirements exactly.

Check your manual for population rules

Server memory support varies by model and BIOS revision, so verify the approved DIMM population order, maximum capacity per channel and any slot-filling sequence before ordering. This kit is validated for the Supermicro H13SSL-NT only; it will not fit systems that require UDIMM, SODIMM or a different DDR generation. Ensure your platform documentation lists DDR5-4800 registered ECC RDIMMs as supported.

Questions about this item

Does the DDR5-4800 PC5-38400 speed run at its rated 4800 MHz on the Supermicro H13SSL-NT?

Yes. The kit is an exact-match upgrade validated for the H13SSL-NT, so the memory controller recognises the 1Rx8 registered ECC modules at full capacity and operates them at the rated DDR5-4800 speed.

Will these 288-pin registered RDIMMs fit the H13SSL-NT's DIMM slots without clearance issues?

The kit uses the 288-pin RDIMM form factor required by the H13SSL-NT; there is no heat spreader, so standard server DIMM clearance applies and the four 16 GB modules populate the board's slots directly.

What is the correct population order when installing all four modules on the H13SSL-NT?

Consult the Supermicro H13SSL-NT manual for the approved DIMM population sequence; the board's memory-population rules dictate which slots must be filled first for full 64 GB operation.
