DELL PRECISION 5820 WORKSTATION

Here’s a closer look at the Dell Precision 5820 Tower Workstation—a high-performance, modular desktop designed for serious professional workloads.

Processor Options

• Built around the Intel LGA 2066 socket (X299/C422 chipset), the Precision 5820 natively supports Intel Xeon W series (Skylake‑W & Cascade Lake‑W) processors with up to 10 cores, advanced vector instructions, and optional vPro support

• It also supports Core X-series CPUs including i7‑78xx, i7‑79xx, as well as Core i9 (9xxx and 10xxx) processors

• According to Wikipedia, the 5820 uses the Xeon W Family (Skylake‑W) generation with dual PCIe x16 support and DDR4 ECC

Memory

• Equipped with 8 DIMM slots supporting up to 256 GB DDR4 ECC memory (2666 MHz), but configuration limits may vary based on CPU—some sources cite up to 512 GB with Xeon W

Graphics Capabilities

• Supports two full-length double-width GPUs, up to 300 W each (600 W total), though a 950 W PSU is required for maximum power delivery.

Storage & Expansion

• Offers robust storage flexibility:

  • Up to six 2.5″ or five 3.5″ SATA/SAS drives, including support for hot-swap front FlexBays.

  • Two front-access hot-plug M.2 NVMe PCIe SSDs and the ability to install up to four NVMe SSDs via the Ultra‑Speed Drive Quad PCIe x16 expansion card, with RAID support.

  • Total storage can scale up to around 68 TB with optimized configurations .

Connectivity & I/O

• PCIe Slots:

  • Xeon W / Core i9X CPUs: 2× x16, 1× x16 wired as x8, 1× x16 wired as x4, and 1× x16 wired as x1.

• Front ports:

  • USB-A, USB-C, and headphone jack

• Rear ports:

  • Multiple USB-A, PS/2, Serial (DE‑9), RJ‑45, audio I/O, and VirtualLink on some configurations.

• Networking:

  • Built‑in Gigabit Ethernet; Wi-Fi 5 and Bluetooth are optional depending on configuration.

Build & Design

• The system has a compact tower form factor with dimensions of approximately 16.45″ (H) × 6.94″ (W) × 20.4″ (D) and a starting weight of around 32 lb (15.9 kg) .

• Designed for high reliability, it supports Dell Optimizer, RMT (Reliable Memory Technology) Pro, and advanced cooling options—important for preventing system crashes and optimizing performance
