Dell Precision 3930 Rack

Dell's 1U single-socket rack workstation on the Intel C246 chipset: Xeon E-2100/E-2200 or 8th/9th-gen Core CPUs, 4 UDIMM slots up to 128 GB, two front drive slots (4 x 2.5" or 2 x 3.5" SATA), two onboard M.2 NVMe, one double-width GPU up to an RTX 6000 / RTX A5500, and optional redundant 550 W PSUs. Built for remote 1:1 users and datacenter-hosted CAD/visualisation seats.

Memory

Slots: 4 DIMM (2 channels, 2 DIMMs per channel)
Type: DDR4 UDIMM, non-ECC or ECC; ECC only with Xeon E and Core i3 processors
Speeds: Dell memory matrix lists 2667 MHz and 3200 MHz DIMM kits
Minimum: 4 GB (1 x 4 GB)
Maximum: 128 GB (4 x 32 GB non-ECC); largest ECC factory config 64 GB (4 x 16 GB)
Population: Populate one DIMM in both channel A and channel B for best performance; mixing DIMM sizes is not supported

Storage

Front drive slots: Drive slot 0 and slot 1 (left and right of the front panel): either 4 x 2.5" or 2 x 3.5" SATA drives, depending on configuration
2.5" drives: SATA 6 Gb/s, OPAL/SED FIPS options, up to 8 TB listed
3.5" drives: SATA 6 Gb/s, up to 16 TB listed
Hot-swap: No: front-load drives are not hot swappable
M.2 onboard: 2 x M.2 2280 Key-M PCIe x4 NVMe on the system board (SSD0, SSD1); SED/OPAL options, up to 4 TB listed
M.2 add-in: 2 more M.2 PCIe x4 NVMe on a Dell Ultra-Speed Drive Duo card in riser 1A slot 2
SATA: 4 SATA connectors on the system board (Intel C246)
RAID: Intel RSTe (legacy OROM or UEFI HII) RAID 0/1/5/10

Graphics

Integrated: Intel UHD 630 (Core) or UHD P630 (Xeon G); DP/HDMI/VGA/DVI through the rear USB-C ports; max 4096 x 2304
NVIDIA: Quadro P400, P620, P1000, P2000, P4000, P5000, P6000; T400, T600, T1000; Quadro RTX 4000, RTX 5000, RTX 6000; RTX A4000, A4500, A5500; RTX 2080 B
AMD: Radeon Pro WX 3200, WX 4100
Power: Cards over 75 W use the graphics power cable to the system-board GPU power connector; dual RTX 4000, RTX 5000 and RTX 6000 configs need dual power supplies
Chassis revision: NVIDIA RTX A4000/A4500/A5500 are only compatible with the updated chassis
Riser: A riser 1 dual graphics card option exists (service manual)

Expansion

Riser 1A slot 1: PCIe Gen 3 x16 full height double width, or single width x8 (bottom)
Riser 1A slot 2: PCIe Gen 3 x8 full height single width (top); used by the Ultra-Speed Drive Duo
Riser 1B (alternative): Two full-height PCI 32-bit/33 MHz slots
Riser 2 slot 3: Fixed riser, PCIe Gen 3 x4 full height single width (all chassis)

Networking
