Exact-fit DDR4 ECC kit for Supermicro

This 64GB kit delivers two 32GB DDR4-2933 unbuffered ECC UDIMMs built to the memory controller's exact rank, voltage and timing requirements. It targets administrators and builders who need validated, error-correcting memory for those specific Supermicro server boards.

Replaces mismatched or non-ECC modules that cause

The jump is worth it when the system requires 2Rx8 organisation, 1.2V operation and CL21 timing at the rated PC4-23400 speed, and when the board's population rules demand matched pairs. Without ECC, silent data corruption and unexpected reboots remain a risk.

Fits the 288-pin UDIMM slots on the named

The kit frees the installer from guessing rank, voltage or timing compatibility and avoids the mismatch that occurs with RDIMM or SODIMM form factors. Builders must still consult the motherboard manual for approved DIMM population order and maximum supported capacity before installation.

Questions about this item

Will this 288-pin DDR4 UDIMM kit fit the DIMM slots on my Supermicro X12SAE motherboard?

Yes, the kit uses the 288-pin DDR4 UDIMM form factor required by the Supermicro X12SAE and X12SCA-F boards, so the modules seat directly into the standard DDR4 DIMM slots.

Do I need to install the two 32 GB modules in a specific slot order on the X12SAE board?

The X12SAE manual defines a DIMM population sequence; follow that order when seating both modules so the memory controller initialises the 64 GB kit at DDR4-2933 with CL21 timings.

The modules have no heat spreader — will they need extra cooling or replacement over time?

ECC UDIMMs at 1.2 V run cool without spreaders; no active cooling or scheduled replacement is needed, and the lifetime warranty covers any module that later develops correctable errors.
