Exact-Match DDR4 Kit

This 32GB kit contains two 16GB DDR4 2933MHz modules built to the precise 1Rx8, CL21, 1.20V specification that Supermicro X12SCQ and X12SCZ-QF motherboards expect. The unbuffered, non-ECC UDIMM form factor ensures the memory controller recognises the full capacity at rated speed without manual tuning.

Verified Fitment for Supermicro Boards

The kit is validated for the X12SCQ and X12SCZ-QF platforms, matching their DDR4 2933 (PC4-23400) requirement and 288-pin UDIMM slot layout. Major OEM chips from Samsung, Micron or Hynix are tested at the rated timing and voltage, delivering a stable, cost-effective upgrade that follows the board's population rules.

Not for ECC or Laptop Builds

Buyers who need error-correcting code memory or SODIMM modules for notebooks cannot use this kit; it is strictly non-ECC desktop UDIMM. Systems requiring registered or load-reduced DIMMs, or a different DDR generation, are also incompatible.

Questions about this item

Will the 1.2 V DDR4 modules need any firmware updates or heatsink additions later?

The kit runs at the standard 1.20 V with no heat spreader fitted; no firmware is involved and no extra cooling is required for normal desktop operation.

What limit appears first when the CL21 2933 MHz sticks run continuously at full load?

The memory controller on the Supermicro X12SCQ or X12SCZ-QF board will hit its maximum supported bandwidth before the modules reach any thermal or timing ceiling.

How much power do the two 16 GB UDIMMs draw during all-day operation?

Each 1Rx8 module operates at 1.20 V, so the pair consumes only a few watts total and adds negligible heat to the chassis.
