Hi, I recently ordered EXP GDC eGPU (BEAST V 7.0) adapter from Banggood. This thread helped me a lot in getting eGPU working with my laptop. I tried setting up with both AMD and NVIDIA EGPU and here is my experience: Configuration 1: Laptop: Dell Precision M4600 DGPU: AMD FirePro M5950 CPU: Intel Sandybridge OS: Windows 10 with UEFI enabled EGPU: Sapphire 270X Dual 550W ATX PSU Everything worked like a charm without any issues with default settings. Had to disable DGPU in device Manager. 3D Mark 11 score was 6196 and First Strike score was around 4100. The card was giving satisfactory performance in DirectX 9 but had very poor performance in DirectX 11, it was only giving 10-12 frames even after overclocking. Therefore I decided to return it and bought ZOTAC GTX 970 instead. Here is the experience with GTX 970. Configuration 2: Laptop: Dell Precision M4600 DGPU: AMD FirePro M5950 CPU: Intel Sandybridge OS: Windows 10 with UEFI enabled EGPU: Zotac GTX 970 550W ATX PSU The system started but gave me a blank screen. I was quite surprised with this therefore I read this whole thread and then decided to play with delay settings. I used both PTD and CTD and then suddenly I got the display with 7s for PTD and CTD switched to ON. I got into Windows, uninstalled AMD drivers and installed Geforce drivers and rebooted the system. It gave me black screen again. I find out that Laptop was not able to reboot successfully when EGPU is connected. So I have to start after disconnecting the EGPU and properly shutdown the system. I connected EGPU again and when I booted into windows and looked in device manager, I got code 12 not enough resources error. I couldn't use Setup 1.x because UEFI was enabled in my BIOS therefore I decided to give DSDT override method a try. After enabling DSDT override GTX 970 worked with my laptop and I can get around 50-60 fps in DirectX 11 in games I played. I also ram 3D Mark 11 and First Strike benchmarks and score was impressive 3dMark11 - NVIDIA GeForce GTX 970 video card benchmark result - Intel Core i7-2720QM Processor,Dell Inc. 08YFGW, First Strike - NVIDIA GeForce GTX 970 video card benchmark result - Intel Core i7-2720QM Processor,Dell Inc. 08YFGW. But this configuration started giving me a lot of laptop starting issues, sometimes system boots with 7s delay and sometimes 7s + CTD and sometimes blank screen. There is no fixed setting on which it always worked plus it always gives blank screen on reboot. After facing these problem for 2 days I decided to take out my oldest laptop Dell E6510 and decided to give it a try because It has NVIDIA DGPU. Here is the experience of setting up GTX 970 on it: Configuration 3: Laptop: Dell E6510 DGPU: NVIDIA NVS 3100 CPU: Intel 1st Gen OS: Windows 10 MBR mode EGPU: Zotac GTX 970 550W ATX PSU Laptop and GPU worked like a charm with everything on default setting, had to disable DGPU. No start or restart issues. Here are the benchmark scores: 3D Mark 11 score - NVIDIA GeForce GTX 970 video card benchmark result - Intel Core i7-640M Processor,Dell Inc. 0N5KHN First Strike score - NVIDIA GeForce GTX 970 video card benchmark result - Intel Core i7-640M Processor,Dell Inc. 0N5KHN Not sure why Physics was performing so badly even after I selected GTX 970 as Physx processor in NVIDIA control pannel. Physics test seem to be highly dependent on CPU. Conclusion: If you want to avoid any trouble with EXP GDC then you have to buy the same make EGPU as your DGPU e.g. if your DGPU is AMD then get only AMD EGPU for your laptop otherwise you have to work with DSDT override/Setup 1.X etc and GPU detect and startup issues. Also you would need latest Intel CPU to get better Physics score and benchmark results.
