64 GB DDR5 6400 CL52 4Rx4 ECC registered RDIMM at 1.1 V for Supermicro X14SDW-64C-SP9F
Size 64GB
This 64GB DDR5-6400 registered ECC module is built for the Supermicro X14SDW-64C-SP9F motherboard. It matches the board's required 288-pin RDIMM form factor, 4Rx4 rank structure, 1.1V operating voltage and CL52 latency. The exact specification ensures the memory controller recognises the full capacity and runs at the rated PC5-51200 speed without manual tuning.
Registered buffering reduces the electrical load on the memory controller, allowing every slot to remain fully populated at the rated 6400 MT/s during continuous workloads. On-die ECC detects and corrects single-bit errors in real time, preventing silent data corruption and unplanned reboots that would otherwise interrupt production services running around the clock.
The DDR5 RDIMM standard used here supports the 64GB density, 6400 MT/s transfer rate and 1.1V voltage specified for this module. Population rules, maximum total capacity and supported rank configurations are defined by the Supermicro X14SDW-64C-SP9F motherboard manual; exceeding those limits will prevent the system from posting or force down-clocking.

The module operates at 1.1V with CL52 timings, a combination that keeps power draw low for continuous server workloads.
The 288-pin DDR5 RDIMM form factor requires a DDR5 registered DIMM slot on a compatible Supermicro motherboard such as the X14SDW-64C-SP9F.
Yes, its registered architecture and ECC function allow it to operate in fully populated DDR5 channels with other registered ECC modules following the motherboard's population rules.
