Dell Precision 3930 Rack Memory Kit

This 32 GB kit contains two 16 GB DDR4 2666 ECC unbuffered UDIMM modules built for the Dell Precision 3930 Rack workstation. Each stick runs at 1.2 V with CL19 latency and uses a 1Rx8 organisation. The modules are validated for that specific platform.

Thermals and Power

Standard DDR4 voltage of 1.2 V keeps power draw low during typical workloads. No heat spreader is fitted, so airflow in the chassis handles cooling without extra noise. ECC operation adds reliability without increasing thermal output.

Upgrade Scope

The kit replaces smaller-capacity DDR4 ECC UDIMMs in the Precision 3930 Rack when 32 GB is required. It is not suited for systems that need registered memory, non-ECC modules, or a different DDR generation. Builders needing more than two modules must look elsewhere.

Questions about this item

How do I install the 288-pin DDR4 ECC UDIMM modules in the Dell Precision 3930 Rack and what step is often missed?

Power off the workstation, open the chassis, align each module's notch with the slot key, press firmly until the retention clips click, then verify in BIOS that both 16GB modules show as 32GB total at 2666 MT/s with ECC enabled.

What maintenance or replacement will this 32GB DDR4 2666 ECC UDIMM kit need over its service life?

No scheduled maintenance is required; keep air vents clear so the modules stay at 1.20 V operating temperature, and replace only if a memory diagnostic reports uncorrectable ECC errors on either 1Rx8 rank.

What limit appears first when the kit runs sustained workloads at 2666 MT/s CL19?

The thermal envelope of the unbuffered 1.20 V modules without heat spreaders is the first constraint; prolonged heavy traffic can throttle throughput before the CL19 latency ceiling is reached.
