System-specific DDR5 ECC RDIMM kit

This 256GB kit contains four 64GB DDR5-4800 registered ECC modules built to the exact rank, voltage and timing the Supermicro H13SSL-N motherboard expects. The 288-pin RDIMM form factor matches the board's memory slots so the system recognises the full capacity at rated speed.

Registered 2Rx4 architecture at 1.1V

The modules use a 2Rx4 organisation with registered buffering and ECC, operating at 1.1V with CL40 latency. This specification offloads the memory controller, allowing every slot to run fully populated while correcting single-bit errors on the fly.

Suits administrators upgrading a Supermicro

Builders who need a different form factor such as UDIMM or SODIMM, or who require non-ECC memory for a workstation, should look elsewhere. The kit is validated only for the named motherboard and its specific population rules.

Questions about this item

What real-world speed does the DDR5-4800 rating deliver inside a Supermicro H13SSL-N?

The kit runs at 4800 MT/s with CL40 timing at 1.10 V, giving the full PC5-38400 bandwidth the motherboard's memory controller expects when all four slots are populated.

How does the registered ECC design affect data integrity and slot population?

Registered buffering offloads the memory controller so every slot runs fully populated at 256 GB total, while ECC corrects single-bit errors on the fly to prevent silent data corruption and unplanned reboots.

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

Yes — the modules are 288-pin DDR5 RDIMMs, the exact form factor the H13SSL-N requires; they are not UDIMMs or SODIMMs and match the board's population rules.
