  • 288-pin RDIMM form factor fits the board's required slot type

Exact-match server upgrade

This 576GB kit delivers twelve 48GB DDR5-4800 Registered ECC RDIMMs at 1.1V with CL40 timing. The modules are built to the precise rank, voltage and timing the Supermicro H13SSL-NT memory controller expects so the full capacity is recognised and runs at its rated PC5-38400 speed.

Who this suits and who should look elsewhere

It suits administrators populating every slot of an H13SSL-NT board with registered ECC memory for maximum capacity and error correction. Builders who need unbuffered UDIMMs, SODIMMs, lower-density modules or a different DDR generation should look elsewhere because this kit only provides 288-pin RDIMMs in a fixed twelve-module configuration.

Sustained-load behaviour

Registered architecture offloads the memory controller so all twelve slots remain stable when fully populated under continuous workloads. On-die ECC catches and corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots during extended production runs.

Questions about this item

What motherboard is required for this 12-module 576GB DDR5 4800 kit?

It is validated for the Supermicro H13SSL-NT motherboard, which accepts 288-pin registered DDR5 DIMMs and supports the 2Rx8 rank structure at 1.1V.

Will these registered ECC modules work if I keep older unbuffered DDR5 DIMMs in the same system?

No. Registered and unbuffered DIMMs cannot be mixed on the same motherboard; the memory controller expects one topology, so all slots must use registered modules.

How can I confirm the kit is running at its rated 4800 MT/s CL40 after installation?

Enter the BIOS or use a tool such as dmidecode to verify each slot shows 4800 MT/s, CL40, 1.1V and registered ECC status across all 12 modules.
