Matched DDR4-2933 Kit for Supermicro Boards

This 16 GB kit contains two 8 GB DDR4 UDIMMs rated at 2933 MT/s with CL21 timings at 1.2 V. The modules are unbuffered, non-ECC, single-rank 1Rx8 parts built with major OEM chips. They are specified to work with Supermicro X12SAE and X12SCA-F motherboards.

Builders with compatible Supermicro X12SAE

Owners of those exact boards who need a straight-forward capacity increase will find the kit drops in at rated speed. Systems that require ECC, registered DIMMs, SODIMM form factors, or a different DDR generation cannot use this memory.

DDR4 2933 CL21 1.2 V unbuffered specification

The DDR4-2933 (PC4-23400) CL21 1.2 V unbuffered rating is the single parameter set the motherboard's memory controller expects. Matching that exact speed, voltage, and timing allows the system to recognise the full 16 GB and run at the rated frequency.

Questions about this item

Will the 2933 MHz CL21 timing hold when the memory controller is saturated for hours?

The kit runs at the rated 2933 MHz with CL21 latency at 1.20 V; without a heat spreader the modules rely on case airflow to maintain those timings under sustained load.

How much noise and heat do the bare 288-pin UDIMMs add when the system runs all day?

The modules have no heat spreader and draw 1.20 V, so they generate minimal heat and no noise of their own; system fan speed will determine overall acoustics.

What must the motherboard provide for this 2 x 8 GB kit to work?

A DDR4 288-pin UDIMM slot that supports non-ECC unbuffered memory at 1.20 V and can run the 1Rx8 modules at 2933 MHz (PC4-23400).
