Dell Precision T3420 Workstation i7-7700 32GB 1TB NVMe

Tower workstation for professional workloads

The Dell Precision T3420 is a tower workstation built around a single Intel Core i7-7700 quad-core processor running at 3.6 GHz. It ships with 32 GB of DDR4 memory and a 1 TB NVMe M.2 SSD, plus Windows 10 Professional 64-bit pre-installed. Integrated Intel HD Graphics 530 provides display output through two DisplayPort and one HDMI connection for dual-monitor support.

32 GB DDR4 at the factory maximum

The system arrives with 32 GB of DDR4 installed across four DIMM slots, matching the 32 GB maximum capacity specified for this Core processor configuration. Memory operates up to 2666 MHz and supports both ECC and non-ECC modules depending on the exact CPU installed. No further memory expansion is possible beyond the factory limit.

Half-height expansion and internal drive bay

A half-height PCIe x16 Gen3 slot and a half-height PCIe x4 Gen3 slot accept low-profile add-in cards such as discrete GPUs or capture cards. An M.2 2280 socket is occupied by the boot NVMe drive. One internal 3.5-inch bay can hold a single 3.5-inch or two 2.5-inch drives for additional storage. The 425 W 80 PLUS Gold power supply delivers 90 % efficiency across 100–240 VAC input.
