Xeon W-2145 Workstation

The Dell Precision T5820 Tower is built for professionals who need sustained multi-threaded compute and certified graphics in a mid-tower form factor. An 8-core Xeon W-2145 running at 3.7 GHz with 4.5 GHz turbo drives demanding CAD, simulation and rendering workloads. 128 GB of registered ECC DDR4-2666 memory across four slots protects data integrity during long jobs. A 2 TB NVMe SSD provides fast project storage and boot.

950 W Gold Power Supply

A Dell 950 W 80 Plus Gold certified supply delivers 90 % efficiency under typical loads, keeping waste heat and fan noise lower than standard units. The Quadro P5000 with 16 GB GDDR5X memory is cooled by the chassis airflow design, so acoustic output stays moderate during GPU-accelerated tasks. Integrated Intel i219 Gigabit Ethernet and Realtek ALC3234 audio add no extra thermal load.

Four DIMM Slots Free

The motherboard offers eight DDR4 slots total; four remain open for expansion up to 256 GB maximum supported capacity. Four DisplayPort outputs on the Quadro P5000 drive multiple 4K displays without additional adapters. The mid-tower chassis leaves room for extra PCIe cards or storage upgrades. Buyers needing more than two terabytes of internal NVMe capacity or a second full-height GPU should verify slot and power headroom before ordering.

Questions about this item

How is the Xeon W-2145 processor installed in the LGA 2066 socket, and which step is commonly missed?

Align the notches, lower the CPU gently, close the retention lever, then apply the pre-applied thermal interface material before mounting the heatsink — skipping the paste step causes overheating.

Which component will need replacement first during long-term use of this Precision T5820?

The 950 watt 80 Plus Gold power supply is the primary wear item; its electrolytic capacitors degrade after several years of continuous operation.

What hardware limit appears first when the Quadro P5000 runs sustained heavy workloads?

The 16 GB GDDR5X frame buffer fills before the GPU core saturates, forcing texture swaps over the PCIe bus.
