Exact-match DDR5 server upgrade

This 64 GB kit contains two 32 GB DDR5-4800 Registered ECC RDIMMs built to the precise rank, voltage and timing the Supermicro H13SSL-N memory controller expects. The modules operate at 1.1 V with CL40 latency and a 2Rx8 organisation so the board recognises full capacity and runs at rated speed without manual tuning.

Registered RDIMM form factor

Each module uses the 288-pin Registered RDIMM layout that the H13SSL-N requires, not a UDIMM or SODIMM variant. The buffered architecture offloads the memory controller, allowing every populated slot to run at full capacity while on-die ECC corrects single-bit errors before they reach production workloads.

DDR5-4800 interface limits

The PC5-38400 standard sets a hard ceiling of 4800 MT/s and CL40 timing, so the kit cannot exceed these figures even if the platform supports faster memory. Population rules and maximum supported capacity are defined by the motherboard manual, so builders must verify slot order and total memory limits before installation.

Questions about this item

Does DDR5 4800 PC5-38400 run at 4800 MT/s on the Supermicro H13SSL-N?

Yes, the kit is rated DDR5 4800 (PC5-38400) and the Supermicro H13SSL-N memory controller supports that speed when populated per the board's rules.

Will these 288-pin RDIMMs fit the Supermicro H13SSL-N DIMM slots?

Yes, the modules are 288-pin Registered RDIMMs, the exact form factor the H13SSL-N requires; they are not UDIMMs or SODIMMs.

What is the correct population order for this 2Rx8 kit on the H13SSL-N?

Install the two 32 GB modules in the slots specified by the Supermicro H13SSL-N manual for a two-DIMM configuration to ensure full capacity and rated speed.
