  • 288-pin RDIMM form factor verified for Supermicro H13SSL-NT slot population rules

Exact-fit DDR5 RDIMM kit

This 384 GB kit contains twelve 32 GB DDR5 4800 RDIMM modules built to the Supermicro H13SSL-NT motherboard's exact rank, voltage and timing requirements. Registered ECC design lets every slot run fully populated at rated speed while correcting single-bit errors on the fly.

Sustained enterprise stability

Registered architecture offloads the memory controller so all twelve slots operate at full capacity without throttling under continuous server workloads. ECC protection catches and corrects single-bit errors in real time, preventing silent data corruption and unplanned reboots during production runs.

Verify population rules first

Server and motherboard memory support varies by model, so consult your system manual for supported capacities, approved DIMM population order and installation steps before ordering. The 288-pin RDIMM form factor is mandatory; UDIMM or SODIMM modules will not fit or function.

Questions about this item

Will the 1.1V DDR5-4800 RDIMMs run cooler than higher-voltage modules under full load?

At 1.1V these registered ECC DIMMs draw less power per module than higher-voltage DDR5 parts, reducing heat output when all twelve slots are populated and the server runs continuously.

Does my Supermicro H13SSL-NT need a specific BIOS revision or CPU stepping to recognise the full 384GB kit?

The kit is validated for the H13SSL-NT motherboard; consult the board manual for the exact DIMM population order and any BIOS version required to support twelve 32GB 2Rx8 registered modules at DDR5-4800.

Can I keep existing DDR5-4800 RDIMMs in the other channels while adding this twelve-module kit?

All modules must match speed, voltage, rank and registered ECC specification; mixing different capacities or timings can prevent the memory controller from training at DDR5-4800 across every channel.
