Hey every one. I am in need of some guidance trying to hook up a GTX 660 ti through a Beast eGPU into my lenovo w540. I have tried updating drivers and software for Thunderbolt 1, booting computer into UEFI only mode to see if the computer detects Nvidia card, and checked for eGPU detection in Thunderbolt Software. I know the computer is communicating with the eGPU because the fans speeds on the GPU are dependent on it being plugged into Thunderbolt, but besides that nothing. Any help would be appreciated.

The Beast is not a Thunderbolt adapter, I am not sure why you think that something will be detected in the Thunderbolt Software.

What exactly are you connecting to the system? Which cabling are you using with the Beast? Which port(s) on the W540 are you connecting it to?

That could be my problem. I originally had it set up through mPCIe with my older computer. I switched to the w540 and was doing research about the best way to get it set up. I read Thunderbolt 1 has better transfer speeds than Express card. I am using a Thunderbolt to HDMI adapter to connect the beast. Is this my issue? I have ordered an Expresscard cable, but would like to try to use the better speeds of thunderbolt.

What you are doing is impossible to get working. You are connecting a native PCIe signal to a Thunderbolt port over a cable that connects wires for two entirely different protocols (DP and HDMI). Not only that, but it is potentially dangerous to your hardware since you're connecting together two things that really should not be connected.

Get the Expresscard cable, or consider getting a Thunderbolt enclosure, but stop trying to do what you're currently doing.
