Exact-fit upgrade for Supermicro boards

This 16 GB DDR4-2933 ECC UDIMM is built to the precise rank, voltage and timing the X12SAE and X12SCA-F memory controllers expect. It installs as a single 288-pin unbuffered module and is recognised at full capacity without manual configuration.

Sustained error-correcting operation

ECC circuitry detects and corrects single-bit errors on the fly during continuous workloads, preventing silent data corruption and unplanned reboots. The 1.2 V operating voltage and CL21 latency remain stable across extended sessions because the module uses major-brand DRAM chips specified for server-grade duty cycles.

1Rx8 unbuffered ECC requirement

This part will only work in systems that accept 1Rx8 unbuffered ECC UDIMMs at DDR4-2933; RDIMM, SODIMM or non-ECC modules are physically or electrically incompatible. Builders needing registered memory, higher capacities per slot or a different data rate must choose a different module.

Questions about this item

How much power does the 1.2V DDR4-2933 module draw when the system runs continuously?

The module operates at 1.20V, the standard DDR4 voltage, so power draw stays at the JEDEC baseline for 2933 MHz ECC UDIMMs.

Does my Supermicro X12SAE or X12SCA-F motherboard need a specific BIOS version or DIMM slot order to recognise this 288-pin UDIMM?

The board requires 288-pin Unbuffered ECC UDIMMs; consult the motherboard manual for supported capacities, approved population order and any BIOS updates before installation.

Can I mix this 1Rx8 CL21 stick with older DDR4 ECC modules that have different ranks or latencies?

Mixing ranks or CAS latencies is not recommended; the memory controller will down-clock to the slowest timing and may disable ECC or fail to train.
