Dell Precision 3660 memory kit

This 64 GB kit contains four 16 GB DDR5 UDIMM modules built for the Dell Precision 3660 Tower Workstation. It targets IT professionals and power users who need maximum supported capacity for memory-intensive workloads on that specific platform.

Four-slot population at 4800 MT/s

The modules run at DDR5 4800 (PC5-38400) with CL40 latency at 1.1 V. All four 288-pin slots are filled by this kit, leaving no free DIMM sockets for further expansion. The unbuffered, non-ECC design matches the workstation's consumer-grade memory controller.

No heat spreaders or software included

The bare modules rely on the chassis airflow of the Precision 3660 for cooling. The package supplies only the four UDIMMs; no configuration utilities, monitoring tools or additional accessories are bundled.

Questions about this item

Does the 4800 MT/s speed hold under sustained load?

The kit runs at DDR5 4800 (PC5-38400) with CL40 timing at 1.10 V, matching the Dell Precision 3660 Tower Workstation specification.

Will the modules run hot or draw extra power during all-day operation?

Each 16 GB UDIMM operates at the standard 1.10 V DDR5 voltage and has no heat spreader, so thermal output and power draw remain at baseline DDR5 levels.

What must the workstation already have for this 64 GB kit to function?

The Precision 3660 Tower Workstation must provide four free 288-pin DDR5 UDIMM slots and a BIOS that supports 1Rx8 non-ECC unbuffered modules at 4800 MT/s.
