  1. Hello, I've posted about this a few times, but still no solution. I have a GTX 570(Have also tried a GTX 560ti) connected to a Dell 6440 dGPU version (Yes, I've already made posts in the Dell 6440 thread by Nando regarding this) using a Bplus PE4C V3.0 (Have also tried with a GDC Beast V8). My problem is that my eGPU shows up in device manger with no errors. Multiple versions of nvidia drivers detect it and install successfully. Everything looks like it should be working. What is happening, is that GPU-Z, dxdiag, nor any benchmarking software will detect it and Windows 10 (Have tried fresh installs of both 10 and Windows 7 Pro) does not detect any external monitors I attach to it. I have tried disabling my dGPU in DIY 1.30 and set it to initialize my eGPU. The best part about this is that it works sometimes! About once every 12 reboots or so, I can uninstall and reinstall my nvidia drivers and the first time my monitors flicker/flash during the install, it works. It will be detected everywhere and it runs absolutely amazing until the next reboot, then I have to mess around the drivers for an hour and it will seemingly magically start working again. I have wrote down every little thing I do to log my actions each time and there is seriously no pattern. I can do the exact same thing (reboot, uninstall drivers, reinstall drivers, reboot, repeat) for an hour and it will work eventually. Possibly Relevant Info: Dell 6440 w/ dGPU option i7 4600MQ 8GB RAM mSata 250GB Samsung Evo Windows 10 Pro (Have tried 7 Pro) x64 GTX 570 (Tried GTX 560ti) Bplus PE4C V3.0 Dock (Have tried GDC Beast V8) Dell DA-2 220W PSU (Have tried 2 other ATX PSU's) I have only found a small handful of people who have posted about this issue, but not resolutions. If anyone could help I would be super grateful. Edit: Also, sleep/resume breaks this when it does work. (I get a Blue Screen) Edit: I'm so invested in this setup right now (Few Hundred Bucks and a couple months of on-off trying to get this reliably working), I'll seriously PayPal $20 to the first person who can help me.
  2. I've been working on getting an egpu working with my Dell e6440 for a couple months now. My e6440 has BIOS A.02 and is running Windows 10 x64 and has the dGPU. I have tried any combination of the three cards I have (gtx 570, gtx 560ti, and R9 270) with the two docks I have (GDC Beast V8.3 and a BPlus PE4C V3.0). With the exception of the R9 270, the eGPU is detected, the drivers are installed successfully, and no errors are reported in device manager (Haven't been able to successfully boot with the R9 270, but I strongly suspect it's an issue with the card as it gives me issues in a desktop environment). Even though everything checks out when I check in Windows, I can't get anything else to see or use it. Attached monitors don't work and no benchmark or system utilities see it. I have tried booting with it attached and trying to attach it after Windows boots, and both have the same result. I hope I'm not missing something completely silly here, as I see in the large post by Nando4 regarding the e6440 says, "A NVidia or AMD card is a straight plug-n-play implementation on a E6440." I have already tried using both docks and both the gtx 570 and 560ti with a e6420 and both worked nearly effortlessly. I have also tried using a clean install of Windows on the e6440 with no effect.
