Targeted Server Upgrade

This 192GB kit delivers twelve 16GB DDR5 RDIMM modules built for the Supermicro H13SSF motherboard. Registered ECC architecture keeps every slot stable at full population while correcting single-bit errors on the fly. The kit suits administrators who need maximum capacity without mixing module sizes.

DDR5 4800 Registered ECC

Each module runs at 4800 MT/s with CL40 latency at 1.10V in a 1Rx8 layout. The 288-pin RDIMM form factor matches the board’s required registered interface so the memory controller sees the correct electrical load and timing at boot.

Capacity and Headroom

Twelve slots filled with 16GB modules yield 192GB total, the full kit capacity for this configuration. Workloads that exceed this footprint will require a platform with higher per-slot limits or additional memory channels not provided by this board.

Questions about this item

What does the 4800 MHz speed mean once the modules are installed in a Supermicro H13SSF motherboard?

The DDR5-4800 rating means the memory controller will run the kit at 4800 MT/s, delivering the full 192 GB capacity at the specified CL40 timing and 1.1 V without downclocking.

What does the PC5-38400 label indicate for this DDR5 RDIMM kit?

PC5-38400 is the peak bandwidth designation that corresponds to the DDR5-4800 data rate, confirming the modules are rated for that transfer speed on a compatible platform.

What physical slot and form factor are required to mount these 16 GB modules?

Each module uses the 288-pin DDR5 RDIMM form factor, so the motherboard must provide DDR5 RDIMM slots; UDIMM or SODIMM slots will not accept them.
