What type of RAM does the Dell OptiPlex 3060 SFF use and what is its maximum capacity?

The Dell OptiPlex 3060 SFF uses DDR4-2666 non-ECC RAM across two SO-DIMM slots, with a maximum capacity of 32 GB via 2×16 GB sticks. The 2666 MHz speed is below the 3200 ceiling on newer DDR4 machines, and 32 GB is a firm limit — fine for standard office workloads, but not for memory-heavy virtualization.
