  1. Setup 1.30 requires MBR. If you edit c:\eGPU\install-disk-image.bat and place "::" in front of the line as is in RED, it will ask you to do a MBR install. Consider too it testing for x2 capability then can install on a USB stick to avoid UEFI to MBR conversion headaches. :check_EFI type bcdtemp.txt | findstr /c:"path" | findstr /c:"winload.efi" > nul :: if NOT errorlevel 1 goto EFI_found echo. echo Can't detect if you have a MBR or EFI Windows installation. choice /C ME /M "Press M (MBR) to do a disk-image install or E (EFI) to cancel and exit." echo. if errorlevel 2 exit /B 1 exit /B 0 A x2 link should automatically show up in Setup 1.30. If not, you can try to set it using PCIe Ports->x2. Though this is likely to fail because it requires two things: 1. That there is a second electrical lane wired to the slot. If the slot can also be used as a x2 2.0 PCIe SSD then that may be possible. 2. That the ME FW or BIOS port bootstraps enable the second electrically wired lane. This is complicated as requires Intel ME FW Tools and an unlocked FW descriptor. There are only two people I know that have publically done this with the more widely available tools for a 3rd gen i-core system. Intel is locking things down more and more to prevent these sort of mods. https://www.techinferno.com/index.php?/forums/topic/7574-14-dell-latitude-e6430-performance-upgrades-and-system-mods/&page=9#comment-127745 https://www.techinferno.com/index.php?/forums/topic/7574-14-dell-latitude-e6430-performance-upgrades-and-system-mods/&do=findComment&comment=115469
  2. automate-eGPU.sh 0.9.8 gives full public and commercial fork privileges Not a Bizon fan but am surprised Bizon took down your script. Your MIT-license.txt for 0.9.8 (Dec 2015) gives *anybody* the legal right to a full fork of 0.9.8. Yes, that means Wolfe, BiZon, Netstor, AKITiO, Razor, Apple, Intel, InXtron or any eGPU community can continue development of your script as a 0.9.8 fork. Those commercial ventures would surely be jumping for joy to see the DIY eGPU community develop and beta test automate-eGPU.sh for them free and would surely like it to continue. I understand if @goalque would now cease it's development - others are profiteering from his work. For example, here is a public Tech Inferno Fan github fork of automate-eGPU.sh 0.9.8 . How many private forks exist? Let's look at this in detail. Here's the MIT-license.txt from the 0.9.8 (Dec 2015) release https://github.com/goalque/automate-eGPU/tree/73a53ac705dd31a927aebc85121aa6bae5df6e46 I see 0.9.9 (Aug-16-2016) has had MIT-license.txt deleted and SCRIPT-license.txt created to rectify this problem. From https://github.com/goalque/automate-eGPU Sierra 10.12 support, issue #31 Goalque, you give BiZoN the quick fix for lines 725 and 754 which they've studied and merged at https://github.com/goalque/automate-eGPU/issues/31#issuecomment-239673651
  3. I've used those common 12V/14A + 12V/15A PSUs before and too noticed PSU buzz under load. It was very prominent during testing of 3dmark vantage and would occasional switch off - the overload protection kicking in. Very questionable whether they can deliver the specified power and maintain longevity. Jetstream GTX970 is one of the performance cards with higher power consumption. The solution here is to get a quality replacement PSU.
  4. A 15" MBP hosts it's dual-Thunderbolt ports controller down a single x4 2.0 link. Adding a second card would increase processing power but if both cards are working at the same time then they share the x4 2.0 bandwidth. Consider offloading the GTX970 and purchasing a GTX1080. That would then give you about 23% less processing power than the GTX970+980Ti all the while having exclusive access to the x4 2.0 bandwidth within a single AKiTiO enclosure.
  5. Ok.. added a EC2-4Gbps reference to the discussion. EC2 is also directly wired to the Southbridge. if x1 2.0 = 373MiB/s, then multiple by 2 to get x1 3.0, then multiple by 4 to get x4 3.0. The result is 2984MiB/s, which is onpar with your 2842Mi/s. So definitely running x4 3.0. EC2-4Gbps (x1 2.0): 373MiB/s link
  6. Moved related discussion to https://www.techinferno.com/index.php?/forums/topic/10579-17-clevo-p870dm-g-gtx108032gbps-ngffm2-pe4c-v41-win10-bloodhawk/
  7. @bloodhawk, I moved the discussion content here since it was referencing your implementation, plus I've summarized your hardware as I know it in the opening post. Pictures of the actual hardware and how the PE4C V4.1 connects would bring it to life. A unique eGPU implementation that's for sure.
  8. You have "Host Pinned to Device: 2842.01 MiB/s" which would mean it's a x4 3.0 (32Gbps) link as reported by GPU-Z. That would be faster than TB3 since there is no additional TB3 controller latency to deal with. Rather, it's a direct electrical link to the Intel southbridge.
  9. Pls run CUDA-Z on your eGPU and post the result. We know from https://www.techinferno.com/index.php?/forums/topic/5226-2013-15-macbook-pro-gt750m-gtx780ti16gbps-tb2-sonnet-iii-d-win81-squinks/ CUDA-Z Host-to-Device Bandwidth TB2 -16Gbps: 1258 MiB/s TB1-10Gbps: 781MiB/s link TB1-8Gbps (x2 2.0): 697MiB/s link EC2-4Gbps (x1 2.0): 373MiB/s link We'll quickly be able to establish it's bandwidth using these reference Thunderbolt results.
  10. The hwinfo64 screenshots confirm the M.2 eGPU port hosting your GTX1080 is running at 8Gbps. It doesn't give the link width. I assume it would be x1 3.0 but GPU-Z would tell us exactly.
  11. 6th Gen i-core systems have Gen3-8Gbps Southbridge PCIe Ports Owner's of the latest 6th-gen i-core systems have seen a speed bump to Gen3 speed (8Gbps) for the Southbridge PCIe ports provided by the HM170/QM170 chipset used to host mPCIe/NGFF ports. This is highlighted in RED below. Gen3 capability is however a lockable feature. Anyone contemplating buying such a system is best advised to use hwinfo64 to peruse the link speed status of the wifi card to see if indeed it's running a Gen3 speed. Reference CUDA-Z Host-to-Device Bandwidth NGFF.M2-32Gbps (x4 3.0): 2842 MiB/s link (17" Clevo P870DM-2) TB3-32Gbps (x4 3.0): 2288 MiB/s link (17" Clevo P870DM-2) TB3-32Gbs (x4 3.0): 1500 MiB/s link (12" Asus Transformer) TB2 -16Gbps (x4 2.0): 1258 MiB/s link (2013 15" MBP) TB1-10Gbps: 781 MiB/s link (2012 MBA) TB1-8Gbps (x2 2.0): 697 MiB/s link (2012 13" MBP) EC2-4Gbps (x1 2.0): 373 MiB/s link (12" Dell E6230) Previously 2nd to 5th Gen i-core systems have Gen2 (5Gbps) Southbridge PCIe ports. 1st gen i-core or older have Gen1 (2.5Gbps) Southbridge PCIe ports Soldered cable eGPU adapters best to attempt a Gen3 link Anybody with one of these systems wanting to attempt a 8Gbps (Gen3) link is best to try using BPlus eGPU adapters with their soldered cable (PE4C V3/4 or PE4L 2.1b). EXP GDC's socketted cable often has reliability issues trying to maintain even a lower specced 5Gbps (Gen2) link.
  12. After booting Setup 1.30 -> Video cards -> dGPU [off], the Chainloader->mode=MBR followed by Chainloader->Test Run, select windows, boot Windows and check if the iGPU and eGPU are the only GPUs enabled. If so, the NVidia Optimus will provide an accelerated internal LCD mode if drivers are configured correctly: https://www.techinferno.com/index.php?/forums/topic/10305-guide-how-to-get-nvidia-optimus-work-in-win10/ If the eGPU isn't detected or gets error 43 then refer to https://www.techinferno.com/index.php?/forums/topic/8947-mpcieec-egpu-troubleshooting-steps/ If the eGPU has error 12 against it then boot Setup 1.30, highlight PCI Compaction->Run compact and hit F1 (help). Over 20 different configuration items will be listed to try. If there is any other problems then pls email or PM me to work through.
  13. Your laptop uses a series 8 chipset whose South bridge mpcie ports are limited to pcie 2.0. PE4C 3.0 a good choice to maintain a reliable link there.
  14. @macfan, suggest you pursue getting the eGPU detected in OSX. That would then at least indicate it's working. Until then it points to you having faulty hardware.
  15. Pls use the delay switches on your EXP GDC adapter to hide it from the BIOS as otherwise the BIOS initializes an unstable state. That will overcome your ACPI_BIOS_ERROR. As mentioned in https://www.techinferno.com/index.php?/forums/topic/8947-mpcieec-egpu-troubleshooting-steps/
  16. There might be some clues by goalque's submissions in the Implementations Guide like this: https://www.techinferno.com/index.php?/forums/topic/6745-2014-15”-macbook-pro-2x-r9_280x16gbps-tb2-netstor-na211tb-win81osx-goalque/
  17. Be sure to get the right command for the DSDT override: https://www.techinferno.com/index.php?/forums/topic/5874-guide-dsdt-override-to-fix-error-12/ You can use the startup.bat->Edit menu to add the command to your startup.bat for automated replay during next Setup 1.30 boot. As for your ACPI BIOS error, suggest you test if this is because of your DSDT override OR due to your BIOS seeing your eGPU on boot and configuring an unstable system. For the latter, can use delay switches on your eGPU adapter to hide the eGPU from the bios during a cold boot: https://www.techinferno.com/index.php?/forums/topic/8947-mpcieec-egpu-troubleshooting-steps/
  18. @LukeHero has updated the opening post explaining the configurations steps to need for this MBP+ eGPU using Win10 (BIOS).
  19. Don't know why it disappeared off here. Found an archive at http://web.archive.org/web/20150829044909/http://forum.techinferno.com/throttlestop-realtemp-discussion/6958-haswell-step-backwards-ivy-bridge-i-have-some-shocking-tdp-results.html I'd say stick with the i7-4702MQ. Dell E6440's cooling system isn't up to dissipating the heat if try to increase UEFI TDP values of the i7-4800MQ processors to allow function in their upper multipliers.
  20. error 43 is usually an hardware initialization issue. Check that you have the PCIe power ports plugged in, you have 75W slot power and your GTX1070 or AKiTiO is not faulty. Remove any PCIe risers and instead run the card in an opened AKiTiO chassis.
  21. Pls check your NVidia driver. If it's 372.90 then install the older 372.70: https://www.techinferno.com/index.php?/forums/topic/10516-error-code-43-with-nvidia-37290-driver/
  22. Pls PM or email me your system model, eGPU details and which Windows version you are using.
  23. This youtube link shows a very easy way of making a molex-to-barrel cable without soldering or splicing any cables.
