Exact-match DDR5-6400 RDIMM

This 32 GB DDR5 registered ECC module is built for the Supermicro X14SDW-64CM-SP9F motherboard. It delivers 6400 MT/s at CL52 with a 1.10 V operating voltage and 2Rx4 organisation. The 288-pin RDIMM form factor matches the board's memory-controller requirements exactly.

Replaces slower or unregistered DIMMs

A jump to this module is worth it when the server needs registered ECC stability at the board's native 6400 MT/s speed. It supersedes any lower-speed DDR5 RDIMM or non-ECC UDIMM that cannot meet the platform's population rules. The registered buffer offloads the memory controller so every slot runs fully populated at rated frequency.

32 GB per module with registered headroom

Each stick provides 32 GB of error-correcting capacity, letting multi-socket configurations scale to the board's maximum supported memory. The 2Rx4 rank structure and 1.10 V operation keep signal integrity tight across all populated channels. Systems that demand more total capacity than the board's slot count allows will need higher-density modules instead.

Questions about this item

Will the 288-pin DDR5 RDIMM fit the Supermicro X14SDW-64CM-SP9F motherboard slots?

Yes, the 288-pin Registered DDR5 DIMM matches the exact form factor the X14SDW-64CM-SP9F requires. UDIMM or SODIMM modules will not fit.

What is the correct population order when installing this 2Rx4 ECC RDIMM?

Consult the Supermicro X14SDW-64CM-SP9F manual for the approved DIMM population sequence; installing modules in the wrong slots can prevent the server from booting.

Does this 1.10V DDR5 module require any firmware updates or ongoing maintenance?

No firmware updates are needed for the memory itself; keep the server BIOS current and run periodic memory diagnostics to catch correctable ECC errors early.
