Dell Precision 3930 Rack Memory Kit

This 16GB dual-channel kit uses two 8GB DDR4 2666 modules built for the Dell Precision 3930 Rack workstation. The PC4-21300 UDIMMs run at 1.20V with CL19 latency and a 1Rx8 organisation. Non-ECC unbuffered design matches the factory specification for straightforward installation.

Buyers upgrading a Precision 3930 Rack

Ideal for IT professionals or workstation owners adding 16GB of validated DDR4 memory to a compatible Dell system. The kit will not suit servers requiring registered or ECC modules, nor boards limited to lower speeds or different pin counts. Systems needing higher capacities per slot should look elsewhere.

2666MT/s DDR4 UDIMM Speed

The 2666MHz data rate is the single figure that decides fit; the Precision 3930 Rack memory controller expects exactly this frequency. Faster or slower modules may default to an unsupported speed or fail to post. Matching the rated 2666MHz ensures stable operation without manual timing changes.

Questions sur cet article

Will the 288-pin DDR4 UDIMM modules need any thermal paste or active cooling added later?

No heat spreader is fitted, so the chips rely on case airflow; no thermal paste or extra cooling is required under normal loads.

What is the first limit reached when the kit runs at 2666 MT/s continuously?

The CL19 latency and 1.20 V JEDEC voltage are the fixed timing and power ceiling; sustained throughput cannot exceed the PC4-21300 rating.

How much heat and noise do the 1Rx8 modules produce when the workstation runs all day?

Unbuffered DDR4 at 1.2 V generates minimal heat and zero acoustic noise; the system fans will dominate any temperature rise.
