Capacity and compatibility

This 576GB kit contains twelve 48GB DDR5 ECC RDIMM modules built for the Supermicro H14SSF motherboard. It runs at 4800MHz PC5-38400 with CL40 latency at 1.1V using 2Rx8 registered chips. The exact rank, voltage and timing match the board's memory controller so the full capacity is recognised at rated speed.

Enterprise servers needing maximum registered ECC

Suits administrators populating every slot on a Supermicro H14SSF system where registered ECC memory is required for error correction and full-slot stability. Not for workstations or desktops that accept only unbuffered UDIMM or SODIMM modules. Buyers who need a different capacity, speed or form factor should look at other kits.

Verify motherboard manual before ordering

Confirm the H14SSF memory population rules, maximum supported capacity per slot and approved DIMM installation order in the system manual. The board requires 288-pin RDIMM modules; UDIMM or SODIMM will not fit. Ensure the BIOS is updated if the manual specifies a minimum version for 48GB density.
