8 GB DDR4-2933 UDIMM for Supermicro X12SCZ-F/TLN4F

This 8 GB DDR4-2933 (PC4-23400) UDIMM is built for the Supermicro X12SCZ-F and X12SCZ-TLN4F motherboards. It runs at 1.2 V with CL21 latency in a 1Rx8 unbuffered non-ECC layout. The 288-pin module uses major OEM chips and installs directly into the desktop DIMM slots.

Who this fits and who it does not

Suits owners of the listed Supermicro boards needing a single 8 GB stick that matches the board's exact rank, voltage and timing rules. Not for systems that require ECC registered modules, SODIMM form factors, or speeds other than DDR4-2933.

The deciding specification

The 1Rx8 unbuffered non-ECC organisation at DDR4-2933 CL21 1.2 V is the single spec that determines compatibility. If your manual calls for a different rank structure, ECC, registered buffering or another speed grade, this module will not work.

Questions about this item

What motherboard must I already have for this NEMIX RAM 8GB DDR4-2933 module to be recognised at full capacity?

The module is an exact-match upgrade for the Supermicro X12SCZ-F and X12SCZ-TLN4F motherboards, using the 288-pin UDIMM form factor those boards require.

Will this CL21 1.20V DDR4 DIMM run reliably alongside any existing memory I keep in the Supermicro board?

Yes — it uses major OEM chips (Samsung, Micron or Hynix) tested for stability at the rated 2933 MHz, CL21 timing and 1.20 V, matching the board's memory-population rules.

How can I confirm the kit is operating at its rated DDR4-2933 speed after installation?

Check the BIOS or a system-information utility; it should report the memory running at 2933 MHz (PC4-23400) with CL21 latency at 1.20 V.
