Dell Precision 3930/5820 memory upgrade

This 8GB DDR4 UDIMM is built for Dell Precision 3930 and 5820 workstations. It suits professionals who need a straightforward capacity increase for multitasking and larger project files. The module is validated for those specific systems.

288-pin non-ECC unbuffered installation

The stick fits standard 288-pin DDR4 slots and runs at 1.2V without ECC or registered buffering. It requires an available UDIMM slot on the motherboard and frees no additional resources beyond the added capacity. Backward compatibility with 2133MHz and 2400MHz bus speeds allows mixed-speed configurations.

Replaces slower or smaller factory modules

Upgrading from lower-capacity or lower-speed DDR4 DIMMs yields noticeable responsiveness gains when the workload exceeds the original memory ceiling. The jump is worth it when current modules limit the number of concurrent applications or the size of datasets you can keep in RAM.

Questions sur cet article

What does CL19 at 2666 MHz mean for sustained workloads?

CL19 is the CAS latency at the rated 2666 MHz speed, which sets the minimum delay for each memory access during long sessions.

How much heat and power does this module produce when running all day?

It operates at 1.2 V with no heat spreader, so power draw and heat output stay low during continuous use.

What must my Dell workstation already have for this UDIMM to work?

A Dell Precision 3930 or 5820 with a free 288-pin DDR4 slot that accepts non-ECC unbuffered memory.
