Exact-match 48GB DDR5-5600 ECC RDIMM

This 48GB DDR5 5600MHz module is built for the Supermicro H13SSL-N motherboard. It uses a 288-pin registered RDIMM form factor with ECC and a 2Rx8 rank structure. The 1.10V voltage and CL46 timing match the board's memory controller requirements for full-speed operation.

Registered DDR5 population limits

Registered DDR5 architecture buffers the command and address signals so the memory controller can drive a fully populated array without signal degradation. ECC corrects single-bit errors on the fly to prevent silent data corruption. The motherboard manual defines the maximum supported capacity per slot and the required population order for multi-DIMM configurations.

Upgrade from UDIMM or lower-capacity RDIMM

This module replaces unbuffered UDIMM or lower-density RDIMM kits that cannot run at full speed when every slot is filled. The jump is worth it when the workload demands maximum registered capacity with error correction and the platform's qualified-vendor list includes this part number.

Questions about this item

Should I choose the 48GB 2Rx8 module or a different capacity for my Supermicro H13SSL-N?

The 48GB 2Rx8 Registered ECC RDIMM matches the exact rank, voltage, and timing your server's memory controller expects, so it is recognised at full capacity and runs at its rated speed.

What does the DDR5 5600 (PC5-44800) speed rating mean once the module is installed in the server?

The module operates at 5600 MT/s with CL46 latency at 1.1V, delivering the bandwidth and timing the platform specifies for fully populated slots.

How does the 288-pin RDIMM interface and Registered ECC design affect real-world operation?

Registered architecture offloads the memory controller so every slot runs fully populated at full capacity, while ECC catches and corrects single-bit errors on the fly.
