192GB DDR5 ECC RDIMM kit

This 192GB kit (4 x 48GB) of DDR5-4800 registered ECC memory is built for servers and workstations that require maximum registered DIMM capacity. It targets administrators upgrading a Supermicro H13SSL-NT motherboard where every slot must run fully populated at rated speed.

Registered buffering and 1.10V operation

The 2Rx8 registered architecture offloads the memory controller so all four slots operate at full capacity without signal degradation. ECC corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots. Modules run at the standard 1.10V DDR5 voltage with CL40 timing.

288-pin RDIMM form factor for Supermicro H13SSL-NT

These modules use the 288-pin RDIMM form factor required by the Supermicro H13SSL-NT motherboard; they are not compatible with UDIMM or SODIMM slots. No heat spreaders are fitted, leaving maximum clearance for dense server chassis airflow. Verify your system manual for approved DIMM population order before installation.

Questions about this item

How do I install the 288-pin DDR5 RDIMM modules on the Supermicro H13SSL-NT motherboard, and what step is often missed?

Power down the server, open the chassis, and insert each 48 GB module into the DIMM slots following the board's population order; the step most people miss is consulting the motherboard manual for the exact slot sequence before seating the 2Rx8 registered DIMMs.

What maintenance or replacement will the 192 GB DDR5 ECC RDIMM kit need over its service life?

No routine maintenance is required; the registered ECC design corrects single-bit errors automatically, and the modules are covered by a lifetime replacement warranty if a hardware fault ever develops.

What limit appears first when the 4 x 48 GB DDR5-4800 CL40 kit runs sustained workloads?

The DDR5-4800 speed and CL40 latency are the fixed operating limits; with registered buffering and 1.1 V operation, thermal throttling or bandwidth saturation will appear before any timing or voltage ceiling is reached.
