Exact-fit DDR4-2933 ECC UDIMM

This 16 GB NEMIX RAM module runs at DDR4 2933 (PC4-23400) with CL21 timing at 1.20 V. The 1Rx8 unbuffered ECC design matches the Supermicro X12SCZ-F and X12SCZ-TLN4F motherboard requirements so the controller recognises full capacity at rated speed.

Thermals and power

Operating at standard 1.20 V without a heat spreader keeps power draw low and noise non-existent in normal use. Passive cooling is sufficient for typical server workloads on these boards.

What the kit changes

The single 288-pin UDIMM adds error-correcting memory that detects and corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots. Buyers who need registered DIMMs, SODIMMs or non-ECC modules cannot use this kit.

Questions about this item

How do I install the 288-pin DDR4 ECC UDIMM into the Supermicro X12SCZ-F and what step is commonly missed?

Align the notch on the module with the key in the slot, press straight down until both retention clips click, then verify the motherboard manual's required DIMM population order for the specific CPU configuration.

What maintenance or replacement will the 1Rx8 ECC memory need over its service life?

No routine maintenance is required; the module either operates correctly or is replaced if ECC logs reveal uncorrectable errors, and the lifetime replacement warranty covers such failures.

What limit appears first when the 16GB DDR4 2933MHz CL21 kit runs sustained workloads?

The JEDEC-rated 1.2V voltage and CL21 latency define the thermal and timing envelope; exceeding either requires manual overclocking beyond the validated specification.
