Exact DDR5-4800 ECC RDIMM kit for Supermicro H13SSW

This 192GB kit contains four 48GB registered DIMMs built to the precise DDR5-4800 CL40 1.1V 2Rx8 specification the Supermicro H13SSW memory controller expects. The modules are 288-pin RDIMMs with ECC and registered buffering so the server recognises the full capacity at rated speed. It is not for systems that require UDIMM or SODIMM form factors.

DDR5-4800 registered ECC limits

The DDR5-4800 (PC5-38400) standard tops out at 4800 MT/s with CL40 timing at 1.1V on this kit. Registered buffering lets every slot run fully populated without overloading the memory controller, while ECC corrects single-bit errors on the fly. Modules without registered buffering or ECC will not meet the board's stability requirements.

Verify H13SSW population rules before ordering

Server memory support varies by model, so consult the Supermicro H13SSW manual for approved capacities, DIMM population order, and installation steps. The board requires 288-pin RDIMMs; UDIMM or SODIMM modules will not fit. Confirm the slot sequence for a four-module kit to ensure the full 192GB is recognised.

Questions about this item

Should I choose this 192GB kit or a smaller capacity for my Supermicro H13SSW?

This kit provides 192GB across four 48GB modules, filling all four DIMM slots on the H13SSW. If your workload needs maximum capacity and the board supports 48GB per slot, this is the correct population.

What does the DDR5 4800 rating mean once installed in the H13SSW?

The modules run at 4800 MT/s with CL40 latency at 1.1V, delivering PC5-38400 bandwidth. The registered design lets the memory controller drive all four slots at this rated speed without down-clocking.

How does the 288-pin RDIMM interface limit or enable performance on this board?

The 288-pin Registered DIMM form factor is required by the H13SSW. Registered buffering offloads the memory controller, allowing full 192GB capacity at DDR5 4800 across all four slots while ECC corrects single-bit errors.
