Exact-match DDR4 upgrade for Supermicro X12SCQ/ZF

This 64 GB kit contains two 32 GB unbuffered UDIMMs built to the DDR4 2933 (PC4-23400) standard. It is intended for owners of the Supermicro X12SCQ or X12SCZ-QF motherboards who need to reach the board's maximum supported capacity with modules the firmware will recognise immediately.

2Rx8 dual-rank organisation at CL21 1.2 V

Each module uses a 2Rx8 layout with CL21 timing and 1.2 V operation, the exact electrical profile the X12SCQ/ZF memory controller expects. Matching rank, voltage and latency is the single specification that determines whether the system will boot at the rated 2933 MT/s speed without down-clocking or instability.

Fills two 288-pin UDIMM slots with non-ECC memory

The kit occupies two DIMM sockets on the motherboard and provides non-ECC unbuffered DDR4, leaving any remaining slots free for future expansion within the board's population rules. It is not suitable for systems that require ECC registered modules, SODIMM form factors, or any memory standard other than DDR4.

Questions about this item

Will the DDR4-2933 speed run at full 2933 MHz on my Supermicro X12SCQ board?

Yes, the kit is spec-matched to the motherboard's DDR4-2933 (PC4-23400) rating and its memory-population rules, so the controller recognises the full 64 GB at the rated frequency.

Does the PC4-23400 rating limit bandwidth compared to faster DDR4 modules?

PC4-23400 defines the maximum transfer rate at 2933 MT/s; the board's memory controller caps throughput at that level, so higher-speed modules would simply downclock to this speed.

Will the 288-pin UDIMM modules fit the DIMM slots on the X12SCZ-QF?

The 288-pin unbuffered UDIMM form factor is exactly what the X12SCQ and X12SCZ-QF require; no ECC, registered, or SODIMM modules will fit those slots.
