DELL Precision T5820 desktop PC Xeon W-2235 32GB DDR4 2TB NVMe Quadro P600 Win 11 Pro

Precision T5820 Xeon workstation

The Dell Precision T5820 is a mid-tower workstation built around an Intel Xeon W-2235 six-core processor running at 3.8 GHz with a 4.6 GHz turbo frequency. It ships with 32 GB of DDR4 2933 MHz registered ECC memory across four slots and a 2 TB PCIe NVMe solid-state drive. The Nvidia Quadro P600 graphics card provides 2 GB of GDDR5 memory and four DisplayPort outputs for multi-monitor setups. Windows 11 Pro is pre-installed and digitally activated.

LGA 2066 platform limits

The LGA 2066 socket supports the installed Xeon W-2235 and allows memory expansion up to 256 GB across eight DDR4 slots, though the board runs at 2933 MHz rather than the 2666 MHz ceiling mentioned in some platform summaries. The 950 W 80 Plus Gold power supply delivers 90 percent efficiency at typical loads, which constrains total system power draw for additional cards or drives. Integrated Intel i219 gigabit Ethernet and Realtek ALC3234 audio are fixed on-board features that cannot be upgraded separately.

Upgrading from entry workstations

This system replaces single-socket desktops that rely on consumer-grade processors and non-ECC memory, offering registered ECC DDR4 and a certified professional GPU driver stack for ISV applications. The jump is worthwhile when workloads demand error-correcting memory, multi-display output from a Quadro card, or a power supply rated for sustained 950 W operation. Buyers who need more than four DisplayPort heads, higher GPU compute performance, or a different form factor should look elsewhere.
