Exact-match DDR5 kit for Supermicro H13SSL-NT

This 256GB kit contains eight 32GB DDR5 4800 RDIMMs built to the exact rank, voltage and timing the board expects. Registered ECC architecture lets every slot run fully populated at rated speed while correcting single-bit errors on the fly. It targets administrators who need maximum supported capacity in a single validated package.

Check motherboard manual before ordering

Verify the H13SSL-NT manual for approved DIMM population order and maximum capacity per channel. The board requires 288-pin Registered RDIMMs — UDIMM or SODIMM modules will not fit or function. Confirm your BIOS revision supports the full 256GB configuration before installation.

Sustained enterprise stability under load

Registered buffering offloads the memory controller so all eight modules remain stable during continuous operation. ECC detects and corrects single-bit errors in real time, preventing silent data corruption during long-running workloads. The 1.1V operating voltage maintains consistent thermal behaviour across extended duty cycles.

Questions about this item

Does the kit ship as eight 32 GB modules or do I need to buy extra sticks to reach 256 GB?

The package contains eight 32 GB DDR5 RDIMM modules for a total of 256 GB; no additional sticks are required.

Should I pick the 2Rx8 CL40 version or a different rank and latency for the Supermicro H13SSL-NT?

The board expects 2Rx8 Registered ECC at CL40 and 1.1 V; this exact kit matches those parameters for full-capacity recognition.

Will the rated 4800 MT/s speed actually run on the H13SSL-NT or does the platform downclock it?

The modules are spec-matched to the motherboard's memory controller, so all eight slots operate at DDR5-4800 when populated per the manual.
