Exact-match 64 GB DDR5-6400 RDIMM

This registered ECC module delivers 64 GB at 6400 MT/s with CL52 latency and 1.1 V operation. It is built for the Supermicro X14SDW-72C-SP9F motherboard and uses the 288-pin DDR5 RDIMM form factor required by that platform. The 4Rx4 organisation matches the board's memory-controller expectations.

Sustained-load behaviour

Registered buffering reduces electrical load on the memory controller, allowing every populated slot to run at the rated 6400 MT/s without down-clocking. ECC detects and corrects single-bit errors on the fly, preventing silent data corruption during long compute runs. The 1.1 V JEDEC voltage keeps power draw predictable under continuous utilisation.

Installation and common issues

Insert the 288-pin RDIMM into the slots specified by the Supermicro manual, following the exact population order for 4Rx4 modules. The most frequent problem is ignoring the board's approved DIMM sequence, which causes the system to recognise only part of the capacity or to fail POST entirely. Verify the configuration in the manual before purchase.
