Exact-match server kit

This 576GB kit delivers twelve 48GB DDR5 RDIMMs tuned to the precise rank, voltage and timing the Supermicro H13SSW memory controller expects. Registered ECC architecture allows every slot to run fully populated at the rated 4800 speed without signal degradation.

Registered ECC RDIMM form factor

The 288-pin Registered (RDIMM) design is the single specification that determines compatibility; a UDIMM or SODIMM will not seat or function in this board. The 2Rx8 organization and 1.1V operation match the motherboard's population rules exactly.

Sustained enterprise stability

Registered buffering offloads the memory controller so all twelve modules maintain full throughput under continuous load, while on-die ECC corrects single-bit errors in real time to prevent silent data corruption during long-running workloads.

Questions about this item

What does 576 GB across twelve 48 GB modules mean for my Supermicro H13SSW?

The kit fully populates the board with 576 GB total, and each module is recognised at its rated DDR5-4800 speed and CL40 timing.

What does the DDR5-4800 PC5-38400 rating limit in practice?

The modules operate at 4800 MT/s with a PC5-38400 data rate, matching the JEDEC DDR5-4800 standard for registered ECC memory.

What physical slot and form factor do these 288-pin RDIMMs need?

They require 288-pin DDR5 RDIMM slots on the Supermicro H13SSW motherboard and will not fit UDIMM or SODIMM sockets.
