  • 32 GB capacity from four 8 GB modules lets you fill the board's slots and run large workloads
  • DDR4-2933 (PC4-23400) speed with CL21 timing matches the controller's rated frequency for stable operation
  • 20 V unbuffered ECC UDIMM design delivers error correction without registered latency
  • 1Rx8 single-rank organisation aligns with the motherboard's population rules for full recognition
  • 288-pin DDR4 form factor fits the Supermicro X12SAE and X12SCA-F boards exactly

Exact-match DDR4 ECC kit for Supermicro X12 boards

This 32 GB kit contains four 8 GB unbuffered ECC UDIMMs rated at DDR4-2933 (PC4-23400) with CL21 timings and 1.20 V operation. The modules use a 1Rx8 organisation and 288-pin layout that matches the memory-controller expectations of the Supermicro X12SAE and X12SCA-F motherboards. Builders who need registered DIMMs or SO-DIMMs should look elsewhere because this kit is strictly unbuffered UDIMM.

ECC protection and verified fitment

On-die error-correcting code detects and corrects single-bit errors in real time, preventing silent data corruption and unexpected reboots during critical workloads. The kit is validated for the exact DIMM population rules of the target Supermicro boards, so the system recognises the full 32 GB at the rated 2933 MT/s without manual tuning. No heat spreaders are included, leaving clearance for dense server chassis.

1Rx8 rank organisation decides compatibility

The single-rank 1Rx8 density per module is the specification that determines whether the motherboard can populate all four slots at the rated speed. Systems requiring dual-rank modules or a different rank-per-channel limit will not support this configuration at full capacity. Consult the board manual for approved population order before purchasing.

Questions about this item

Will the 1.20 V ECC UDIMM modules need replacement after a certain number of duty cycles?

DDR4 ECC UDIMM modules have no specified wear-out cycle limit; they remain in service until a hardware fault occurs or the platform is retired.

What limit appears first when the four 1Rx8 sticks run at 2933 MHz continuously?

The memory controller's maximum supported capacity and population rules for the Supermicro X12SAE or X12SCA-F board determine the practical ceiling.

How much heat do the 1.20 V CL21 sticks produce when the system runs all day?

Operating at 1.20 V without heat spreaders, the modules generate typical DDR4 UDIMM thermals; adequate chassis airflow keeps temperatures within specification.
