Exact-match DDR5 ECC RDIMM kit

This 64GB kit contains two 32GB DDR5 4800 registered ECC modules built to the precise rank, voltage and timing the Supermicro X14SDV-20C-SP3F memory controller expects. The 2Rx8 organization and CL40 latency let the board recognize full capacity and run at the rated PC5-38400 speed without manual tuning. It is intended for administrators upgrading that specific server platform.

288-pin registered form factor

The 288-pin RDIMM form factor is the only type the X14SDV-20C-SP3F accepts; UDIMM or SODIMM modules will not seat or function. Registered architecture buffers the command and address signals so every slot can be populated at full capacity while maintaining signal integrity. ECC circuitry detects and corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots in production workloads.

Lifetime support and verification

Each kit is verified for fitment against the Supermicro X14SDV-20C-SP3F motherboard and ships as a matched pair to satisfy the board's population rules. Buyers should still consult the system manual for approved DIMM order and maximum supported capacity before installation. The modules carry a lifetime replacement warranty with free US-based technical support for the duration of ownership.

Questions about this item

What speed does the DDR5 4800 interface run at on the Supermicro X14SDV-20C-SP3F board?

The kit operates at DDR5 4800 (PC5-38400) with CL40 latency at 1.10 V, matching the motherboard's rated memory speed.

What physical slot and form factor do these modules need to fit the Supermicro X14SDV-20C-SP3F?

Each 32 GB module is a 288-pin RDIMM; the board requires registered DIMMs, not UDIMM or SODIMM, and the kit provides two sticks for the supported slots.

How are the modules installed, and which population rule is often missed?

Insert both RDIMMs into the correct channel slots per the motherboard manual; the common mistake is skipping the prescribed population order, which prevents full 64 GB recognition.
