Exact-match DDR4 upgrade

This NEMIX RAM module delivers 8GB of DDR4 2933MHz memory built to the PC4-23400 standard with CL21 latency and 1.2V operation. It uses a 1Rx8 rank configuration on a 288-pin UDIMM form factor and is verified for Supermicro X12SCQ and X12SCZ-QF motherboards.

Verify motherboard population rules

Before ordering, consult your system or motherboard manual for supported capacities, approved DIMM population order, and installation steps. The module is non-ECC and unbuffered, so confirm your board accepts this type and that the rank and voltage match the controller requirements.

Fits standard desktop DIMM slots

The 288-pin UDIMM design installs directly into compatible desktop memory slots without requiring ECC or registered module support. It uses major OEM chips from Samsung, Micron, or Hynix tested at rated speed and timing, freeing you from compatibility guesswork while adding capacity to your existing platform.

Questions about this item

Does the module arrive as a single stick or a kit, and are any extra parts needed for installation?

The package contains one 8GB DDR4 2933MHz UDIMM; no cables, brackets or additional hardware are required for a standard desktop DIMM slot.

Should I pick this 8GB CL21 version or look for a different capacity or latency?

This part is an 8GB single-rank CL21 module validated for Supermicro X12SCQ and X12SCZ-QF boards; choose it when your system manual calls for exactly that capacity, rank and timing.

What does the 2933MHz rating mean once the DIMM is seated in a compatible Supermicro board?

The board's memory controller will recognise the SPD profile and run the module at 2933MHz with CL21 timing at 1.2V, delivering the rated PC4-23400 data rate without manual configuration.
