32 GB DDR4 2933 ECC UDIMM

This 32 GB DDR4 module runs at 2933 MT/s with CL21 latency and 1.2 V operation. It is an unbuffered ECC UDIMM built with a 2Rx8 rank structure on a 288-pin PCB. The part is validated for Supermicro X12SAE and X12SCA-F motherboards that require DDR4 2933 PC4-23400 ECC memory.

Suited for ECC workstations

The module fits systems that accept unbuffered ECC UDIMMs at the specified speed and rank. Builders needing registered DIMMs, SODIMMs, non-ECC memory, or a different voltage should select a different part. Capacity beyond a single 32 GB stick depends on the motherboard's slot count and population rules.

2Rx8 rank at 1.2 V

The 2Rx8 organisation at 1.20 V is the specific electrical signature the memory controller expects. A mismatched rank or voltage will prevent the system from recognising the full 32 GB or running at the rated 2933 MT/s. Verify the board's approved DIMM population order before installation.

Questions about this item

Should I pick this 32GB 2Rx8 CL21 kit or a different capacity for my Supermicro X12SAE?

This kit provides exactly 32GB in a single 2Rx8 ECC UDIMM that matches the board's required rank, voltage, and timing so the controller recognises full capacity at the rated 2933MHz speed.

What does the 2933MHz rating deliver once installed in a Supermicro X12SAE?

The module runs at DDR4-2933 (PC4-23400) with CL21 latency at 1.2V, giving the memory controller the precise frequency and timing it expects for stable operation at full rated throughput.

How does the 288-pin DDR4 ECC UDIMM interface limit real-world use?

The 288-pin unbuffered ECC form factor fits only DDR4 UDIMM slots — not RDIMM or SODIMM sockets — and the ECC function corrects single-bit errors on the fly to prevent silent data corruption.
