Precision T5820 workstation for professional compute

The Precision T5820 tower pairs an Intel Xeon W-2225 processor running at 4.1GHz with a 4.6GHz turbo frequency with 128GB of registered ECC DDR4 memory across four 32GB modules. An Nvidia Quadro RTX 4000 graphics card provides 8GB of GDDR6 memory and outputs through three DisplayPort 1.4 connectors plus one USB-C port. The system ships with Windows 11 Pro installed on a 2TB PCIe NVMe solid-state drive.

Thermals noise and 950W Gold power supply

A 950-watt 80 Plus Gold certified power supply rated at 90 percent efficiency delivers stable power to the CPU, GPU and memory subsystem. The mid-tower chassis uses Dell's engineered airflow paths to manage heat from the four-core Xeon processor and the RTX 4000 card during typical professional workloads. Integrated Realtek ALC3234 high-definition audio and an Intel i219 gigabit Ethernet controller operate without adding measurable acoustic load.

Sustained load behaviour

Registered ECC DDR4 memory at 2666MHz maintains data integrity during extended rendering, simulation or analysis tasks that run for hours. The 2TB NVMe solid-state drive sustains high throughput for large dataset access without the thermal throttling seen in smaller drives. Four memory slots remain available for future expansion up to the platform maximum of 256GB.

Questions about this item

How do I install the four 32 GB DDR4 2666 MHz Registered ECC modules into the eight available slots?

Populate the four modules into the CPU-channel-matched slots first — typically slots 1, 3, 5 and 7 — so each channel gets one DIMM; the common mistake is filling sequential slots and leaving a channel empty.

What maintenance will the 950 W 80 Plus Gold power supply need over time?

Clean the intake filter every few months and watch for fan-noise changes; the unit has no user-serviceable parts, so a full PSU swap is the only fix if efficiency drops or voltages drift.

What thermal limit appears first when the Xeon W-2225 sustains its 4.6 GHz turbo on all four cores?

The CPU package power ceiling is reached before the cooler saturates, causing the firmware to throttle clocks back toward the 4.1 GHz base frequency within seconds.
