32GB DDR4 2666 UDIMM for Supermicro systems

This 32GB DDR4 2666 module is built for Supermicro desktop and workstation motherboards such as the MBD-C9Z390CG-IW. It targets IT professionals and enthusiasts who need a single high-density stick to expand memory capacity in compatible platforms. The non-ECC unbuffered design suits standard desktop workloads.

CL19 1.20V operation without heat spreader

Running at CL19 and 1.20V, the module follows standard DDR4 power characteristics for its speed grade. No heat spreader is fitted, so airflow from the CPU cooler or case fans provides the only cooling. Acoustic output and power draw remain at typical DDR4 UDIMM levels for this voltage and frequency.

Single 288-pin 2Rx8 stick frees remaining slots

The 288-pin 2Rx8 form factor occupies one DIMM slot, leaving other channels open for further expansion up to the motherboard limit. No extra cables, brackets or BIOS steps beyond normal memory installation are required. Builders who need ECC, registered modules or speeds beyond 2666 MT/s should look elsewhere.

Questions about this item

How do I install this 288-pin DDR4 UDIMM and what step is often missed?

Align the notch on the 288-pin DDR4 UDIMM with the motherboard slot key, press firmly until both retention clips click, then verify the module is recognised at 2666 MT/s in the BIOS.

What maintenance or replacement will this 32 GB DDR4 module need over time?

The module has no heat spreader and no moving parts, so no routine maintenance is required; replacement is only needed if a memory test reports errors.

What limit appears first when this CL19 1.2 V kit runs sustained workloads?

The CL19 latency at 1.2 V sets the performance ceiling before thermal throttling becomes a factor on this unbuffered UDIMM.
