Exact-match DDR4 upgrade

This 32GB DDR4-2933 module delivers the precise rank, voltage, and timing your Supermicro X12SAE or X12SCA-F memory controller expects. It installs as a standard 288-pin UDIMM and is recognised at full capacity without manual configuration. Builders needing ECC, registered DIMMs, or SODIMM form factors should look elsewhere.

Thermals and power

Operating at 1.2V without a heat spreader, the module runs cool under normal desktop workloads and draws minimal power from the memory rail. The unbuffered design adds no active components that could generate extra noise or heat. Systems with restricted airflow around the DIMM slots will not see thermal issues from this part.

CL21 timing at 2933 MT/s

CAS latency 21 at DDR4-2933 (PC4-23400) is the single spec that determines whether this kit matches your board's qualified-vendor list. The 2Rx8 organisation and 1.20V operation must align exactly with the motherboard's supported population rules for stable operation at rated speed.

Questions about this item

How do I install this 288-pin DDR4 UDIMM in my Supermicro X12SAE motherboard and what step is often missed?

Align the notch on the module with the slot key, press straight down until both side clips click, then verify the DIMM population order in the motherboard manual so the 2Rx8 rank is recognised at full 32GB capacity.

What maintenance or replacement will this non-ECC UDIMM need over time?

No scheduled maintenance is required; the module has no heat spreader and uses major OEM chips rated for 1.20V operation, so replacement is only necessary if a memory test reports errors.

What limit appears first when this CL21 2933MHz kit runs sustained workloads?

The CAS latency of 21 cycles at DDR4-2933 sets the timing ceiling, and the fixed 1.20V voltage prevents further frequency scaling under prolonged load.
