NVIDIA Quadro K4000 workstation GPU

The NVIDIA Quadro K4000 is a workstation graphics card built on the Kepler architecture with 768 CUDA cores and 3GB of GDDR5 memory across a 192-bit bus. Core clock runs at 810MHz with memory at 1404MHz for 5.6Gb/s effective bandwidth. It connects via PCI Express 3.0 x16 and occupies a single slot.

Suits CAD and multi-display setups

Professionals running DirectX 12 or OpenGL 4.6 applications on Windows or Linux will find the dual DisplayPort and single DVI outputs drive up to 4096 x 2160 digital resolution. The 6-pin auxiliary power connector and single-slot design fit many workstation chassis. Buyers needing more than 3GB frame buffer or additional display outputs should consider other options.

IBM 03T8312 part number included

The card carries IBM part number 03T8312 for asset tracking in managed deployments. No extra software bundles or adapters are mentioned in the specifications. The package delivers the graphics board itself with its standard bracket and cooler.

Questions about this item

What power connector must my PSU provide for the 6-pin auxiliary input?

The card needs a single 6-pin PCIe power connector from the supply.

Will the PCIe 3.0 x16 interface run on my older PCIe 2.0 x16 motherboard slot?

Yes, the card is backward compatible and will operate at PCIe 2.0 x16 speeds.

How can I verify the 768 CUDA cores are recognised after driver installation?

Open NVIDIA Control Panel or run nvidia-smi; both will list 768 CUDA cores for the Quadro K4000.
