Exact-Match Upgrade for Supermicro X12SCQ /

This 128GB kit contains four 32GB DDR4 2933 UDIMM modules built to the precise rank, voltage, and timing your motherboard expects. It is designed for desktop PCs using the Supermicro X12SCQ or X12SCZ-QF boards and installs as a matched set for full-capacity recognition.

DDR4 2933 Unbuffered UDIMM Interface Limits

The DDR4 2933 standard delivers PC4-23400 bandwidth through a 288-pin unbuffered connection at 1.2V. This kit operates at CL21 latency with a 2Rx8 organisation, so the memory controller must support that exact speed, timing, and rank configuration for stable operation at rated specifications.

2Rx8 Rank Organisation Determines Compatibility

The dual-rank 2Rx8 layout on each 32GB module decides whether your board's memory population rules allow all four slots to run at 2933MHz. Systems limited to single-rank DIMMs or lower maximum ranks per channel will not support this kit at its rated speed or capacity.

Questions about this item

Should I pick the 128 GB kit or buy single 32 GB modules to reach the same total?

The kit supplies four matched 32 GB modules that are tested together, so the motherboard sees identical timing and rank on every slot and boots at the rated 2933 MT/s without manual tuning.

Will the CL21 CAS latency slow down my Supermicro X12SCQ compared with lower-latency RAM?

The board's memory controller is validated for CL21 at 2933 MT/s, so the kit runs at the full rated speed without down-clocking; tighter timings would require modules the board does not officially support.

Does the PC4-23400 rating limit bandwidth on a DDR4 2933 system?

PC4-23400 is the peak transfer rate for DDR4 2933, so the kit delivers the maximum bandwidth the memory controller can use at that speed.
