Instructions for Connecting to NVIDIA GeForce GTX 3090 eGPU

In lab mc342 are seven external GPU systems, or eGPU, each equipped with an NVIDIA GTX 3090 Graphics Accelerator card which are available for use by Computer Science students.


System Requirements

  • You must have a Windows laptop with a Thunderbolt-3 (or faster) port.  Note that USB-C has the same shape port as Thunderbolt.  A Thunderbolt 3 port looks like a standard USB-C port on any laptop or desktop computer, but can be distinguished by a lightning bolt icon printed next to it.  
  • Mac systems are not supported

Example of Thunderbolt-3 cable.
