Exact-Match Server Upgrade

This 256 GB kit delivers four 64 GB DDR5 RDIMMs rated at 6400 MT/s with CL52 latency and 1.1 V operation. It is built for the Supermicro X14SDV-36C-SP3F motherboard and provides registered ECC memory that the platform expects.

Registered DDR5 Limits

Registered DDR5 RDIMMs buffer address and command signals so the memory controller can drive a fully populated bus at rated speed. The 288-pin form factor and 4Rx4 organisation are required by this board; UDIMM or SODIMM modules will not fit or function.

Pre-Install Checks

Confirm the motherboard manual for supported capacities per slot and the approved DIMM population sequence before ordering. Verify that the system firmware recognises 4Rx4 registered ECC modules at 6400 MT/s and that all four slots can be populated simultaneously.

Questions about this item

Should I choose the 256GB 4x64GB kit or a different capacity for my Supermicro X14SDV-36C-SP3F?

The 256GB kit provides four 64GB RDIMMs that fill the board's slots exactly as the memory controller expects. Other capacities would change the rank layout and may not run at the rated DDR5 6400 speed.

What does the DDR5 6400 rating deliver once the modules are installed in the server?

The modules operate at 6400 MT/s with CL52 latency at 1.1V, giving the full PC5-51200 bandwidth the board's memory controller is designed for when all four slots are populated.

How does the 288-pin RDIMM interface and registered design affect real-world operation?

The registered architecture buffers each command so the memory controller can drive all four 4Rx4 modules at DDR5 6400 without signal degradation, while ECC corrects single-bit errors on the fly.
