64GB DDR5 6400 ECC RDIMM for Supermicro

This 64GB DDR5-6400 Registered ECC RDIMM is built for the Supermicro X14SDV-36CE-SP3F motherboard. It delivers 64GB per module at PC5-51200 speed with CL52 latency and 1.1V operation. The 4Rx4 registered design ensures full-capacity recognition when every slot is populated.

Replaces lower-capacity

Upgrading from smaller Registered ECC modules or slower DDR5 speeds is worthwhile when your workload needs maximum density per slot and the memory controller expects 4Rx4 timing at 6400 MT/s. The jump matters for virtualization hosts, database nodes, and compute clusters that hit capacity limits before CPU limits.

Fits 288-pin RDIMM slots on the validated

The module requires a motherboard that accepts 288-pin Registered DDR5 DIMMs with 1.1V VDD and supports the 4Rx4 rank configuration. It frees DIMM slots by providing 64GB in a single stick, letting you reach higher total memory without exceeding the board's slot count. Consult the system manual for approved population order before installation.

Questions about this item

Will the 288-pin DDR5 RDIMM fit the memory slots on my Supermicro X14SDV-36CE-SP3F motherboard?

Yes, this module uses the 288-pin RDIMM form factor required by the X14SDV-36CE-SP3F. The board accepts registered DDR5 DIMMs only, not UDIMM or SODIMM, so the physical keying and notch position match the slots exactly.

What is the correct installation sequence for populating all channels on the X14SDV-36CE-SP3F with these 4Rx4 modules?

Install DIMMs in the order specified by the Supermicro manual for your CPU configuration. A common error is filling slots sequentially from slot one instead of following the per-channel population table, which can prevent the system from recognising the full 64GB capacity or running at 6400MT/s.

How do I know when a 4Rx4 registered ECC module like this needs replacement?

Monitor the system event log for corrected ECC error counts. A rising trend of single-bit corrections on a specific DIMM indicates degrading DRAM cells; replace that module before uncorrectable errors cause a halt. The registered buffer and ECC logic itself is solid-state and does not wear out.
