Exact-match DDR5 kit for Supermicro X14SDW

This 128GB kit contains four 32GB DDR5 6400 RDIMMs built to the exact rank, voltage and timing the Supermicro X14SDW-40C-SP9F memory controller expects. Registered ECC architecture offloads the controller so every slot runs fully populated at rated speed while ECC corrects single-bit errors on the fly. The modules install in the 288-pin RDIMM slots this board requires.

DDR5 6400 speed and 1.1V voltage ceiling

DDR5 6400 (PC5-51200) sets the maximum data rate and the 1.1V operating voltage the memory controller supports; faster modules will down-clock and higher-voltage modules will not be recognised. Registered buffering allows full four-slot population without signal degradation, but the board's population rules still dictate which slots must be filled first.

2Rx4 registered ECC RDIMM form factor

The 2Rx4 registered ECC RDIMM layout is the single specification that determines whether this kit will be recognised at full capacity and run at DDR5 6400 on the target motherboard; a UDIMM, SODIMM or different rank configuration will not work.

Questions about this item

Should I choose this 128GB 4x32GB kit or a different capacity for my Supermicro X14SDW-40C-SP9F?

This 128GB kit uses four 32GB DDR5 6400 RDIMMs. The board has 14 DDR5 slots; check its manual for the approved population order and maximum capacity per slot before deciding.

Will the DDR5 6400 speed run at 6400 MT/s once installed in the Supermicro X14SDW-40C-SP9F?

The modules are rated DDR5 6400 (PC5-51200) at 1.1V CL52. The X14SDW-40C-SP9F memory controller must support that data rate; if it caps lower, the DIMMs will downclock to the highest speed the board allows.

Does the 288-pin Registered ECC RDIMM interface limit how many modules I can install?

The 288-pin RDIMM form factor is required by the X14SDW-40C-SP9F. Registered architecture lets the board run all 14 slots fully populated at rated capacity, while ECC corrects single-bit errors on the fly.
