Hi, I've got a Thinkpad X61 (C2D, 2GB RAM) running Win 7 Pro SP1 to which I'd like to connect my eGPU. I've made my own PCB (MXM <-> mPCIe adapter) so I'm testing it, but I have too many variables for the moment. This is a clean install of Windows. I have an NVIDIA Quadro K610M card and have installed driver package 364.51. I have done the Large Memory DSDT override successfully and conquered error 43 using the PCI dump in Setup 1.30. It detects the GPU fine and initializes it, once I get to Windows everything *seems* to work, but only if I disable my internal Intel GPU (ok for now, I'll fix that later). Device Manager tells me I have a working NVIDIA card. GPU-Z detects it fine as well. The issue I'm having is that I'm not getting anything at all on the VGA port. I realize this very well might be a HW issue, but I'm not convinced yet. I would like to try to use the NVidia Control Panel to verify what's going on, but I can't open it. nvcplui.exe is running in the Task Manager, but I don't get anything else. I read that this is a known issue with no particular fix and I wanted to see what folks here thought, given that this is being used for an eGPU. By the way, the normal "Adjust resolution" dialogue doesn't detect any 2nd screen, but then it seems to be specific to the iGPU (which is listed as the hardware under "Advanced") so it shouldn't work anyway. Is there a way to get the built-in Windows Control Panel to detect / use the new GPU? Any input is appreciated, and further clarification gladly provided. Thanks! Rafael
