Server memory kit for Supermicro H13SSF

This 384GB kit contains twelve 32GB DDR5 RDIMM modules rated at 4800MHz with CL40 timing. Registered ECC architecture provides the error correction and signal buffering required by the Supermicro H13SSF motherboard for stable operation at full capacity.

Verify board population rules before ordering

The H13SSF memory controller expects 2Rx8 registered DIMMs at 1.1V. Consult your motherboard manual for supported capacities, approved slot population order, and any BIOS version requirements to ensure all twelve modules are recognised at rated speed.

288-pin RDIMM form factor with no heat spreader

Modules use the standard registered DIMM pin-out this board requires, not UDIMM or SODIMM. Bare circuit boards allow tight slot spacing in dense server chassis, while registered buffering keeps electrical load low across all twelve slots.

Questions about this item

Does the 12-module kit include anything besides the 32GB DDR5-4800 RDIMMs, or do I need to buy heatsinks separately?

The box contains twelve 32GB DDR5-4800 CL40 2Rx8 registered ECC RDIMMs and nothing else; no heat spreaders are included or required.

Why choose the 384GB 12x32GB kit instead of a smaller capacity for the Supermicro H13SSF?

This kit fills all twelve DDR5 slots with matched 2Rx8 modules so the memory controller recognises the full 384GB at the rated 4800MT/s without population conflicts.

What does the CL40 rating mean when the kit is running in a fully populated Supermicro H13SSF?

CL40 is the CAS latency the modules are validated for at DDR5-4800; the registered design keeps every slot stable at that timing even with all twelve DIMMs installed.
