Exact-Match DDR5 Kit

This 128GB kit contains four 32GB DDR5 4800 RDIMM modules rated at CL40 and 1.1V. It is built for the Supermicro H13SSF motherboard and uses the 288-pin Registered ECC form factor that board requires.

Sustained Enterprise Stability

Registered buffering offloads the memory controller so all slots run fully populated at rated speed under continuous load. ECC corrects single-bit errors on the fly to prevent silent data corruption and unplanned reboots during long production runs.

Build and Fitment

Modules ship without heat spreaders to fit dense server DIMM layouts. The 2Rx8 rank structure matches the board's population rules. Verify your system manual for approved capacity limits and slot order before installation.

Questions about this item

How much power does the 128GB DDR5 4800 kit draw when the Supermicro H13SSF runs continuously?

Each 32GB module operates at 1.1V. With four RDIMMs installed the total voltage per DIMM stays at 1.1V, so the memory subsystem draws only the current the platform allocates at that voltage.

What motherboard feature is required for these 288-pin registered ECC modules to function?

The Supermicro H13SSF must provide DDR5 RDIMM slots that support registered ECC memory and a memory controller able to address 2Rx8 ranks at 4800 MT/s.

Will the 2Rx8 organisation work alongside any existing DDR5 RDIMMs already installed in the H13SSF?

Yes, provided the board's population rules allow mixing 2Rx8 modules in the remaining channels and the BIOS is configured for the same 4800 MT/s CL40 timing.
