Exact-match DDR4 ECC kit

This 32 GB kit contains two 16 GB unbuffered ECC UDIMMs rated at DDR4-2933 with CL21 timings at 1.2 V. The modules use a 1Rx8 rank structure and 288-pin form factor so the memory controller recognises the full capacity at its rated speed.

Verify board population rules

The kit is validated for Supermicro X12SCZ-F and X12SCZ-TLN4F motherboards that require unbuffered ECC UDIMMs. Check your system manual for supported capacities, approved DIMM population order and installation steps before ordering.

Standard voltage thermals

Operating at 1.2 V without a heat spreader, the modules run at standard DDR4 power levels in typical server or workstation workloads. Passive airflow from chassis fans is sufficient for normal use.

Questions about this item

What comes in the kit and do I need anything else to install it?

The kit contains two 16 GB DDR4 ECC UDIMM modules for a total of 32 GB. No extra parts are required; they plug directly into the 288-pin DIMM slots on the Supermicro X12SCZ-F or X12SCZ-TLN4F motherboard.

Should I pick this 32 GB kit or a different capacity for my Supermicro board?

Choose this 32 GB kit if your workload needs 32 GB and the board manual confirms two 16 GB 1Rx8 UDIMMs in the supported population order. Select another capacity only if the manual lists a different approved configuration.

Will the DDR4-2933 CL21 rating actually run at that speed once installed?

Yes. The modules are spec-matched to the board's DDR4-2933 (PC4-23400) memory controller, so the system recognises the 1Rx8 rank, 1.2 V voltage and CL21 timing and operates at the rated 2933 MT/s.
