P-Mac Posted June 21, 2016 Share Posted June 21, 2016 Hi all, thanks to your posts and knowledge, I was able to get an eGPU rig with a GTX 980 up and running with very few issues! It's been great so far. One of the lingering issues I've had is having to play the lottery whenever I start up the Mac...it seems like only one time out of 5 will the machine actually POST and play the startup chime and continue booting. Most other times, the GPU will initialize (I see the LEDs turn on and the fans spin up and return to idle), but the Mac just sits there at a black screen and never plays the startup chime. No amount of shuffling between thunderbolt ports (on both the Thunder2 and the laptop), or praying to the PC Master Race gods has seemed to have any effect on whether the machine will successfully boot or not. Sometimes it'll boot right on the first try, and do so 10 times in a row, other times I'll have to sit there and hold power to force-shutdown the machine and retry 6 or 7 times before it'll boot. Any ideas? Specs are as follows: 2014 MacBook Pro 15", i7-4980HQ, GT 750m Akitio Thunder2, MSI GTX 980 Gaming 4G, Corsair 650w PSU Quote Link to comment Share on other sites More sharing options...

johndshea Posted October 9, 2016 Share Posted October 9, 2016 I have the same problem, same hardware (running a 970 though, not a 980). I still haven't found a solution. Quote Link to comment Share on other sites More sharing options...
ti_padawan Posted October 10, 2016 Share Posted October 10, 2016 I don't think there's a clear solution for everyone regarding the notorious black screen thing at the moment, but the following threads could at least bring you some ideas and things to try (in case you haven't visited them yet), depending on whether you boot into Windows or OS X. On a side note, it might be worthwhile to make sure that the drivers (the system folders) "match" among MBP 2013/14 (GT 750M; black screen issue) and MBP 2012 (GT 650M; no black screen issue as far as I can tell). If not, significant differences could, perhaps, hold a key to something subtle but potentially important. Quote Link to comment Share on other sites More sharing options...
P-Mac Posted December 20, 2016 Author Share Posted December 20, 2016 A little late, but I'd like to reply that when running macOS (shutting down from macOS, starting back up in macOS), running the goalque script in "-a mode" actually solved this issue 100% for me. That being said, Windows booting is still the same crapshoot, and running the script in -a mode seems to prevent Windows from detecting the eGPU on first startup (gotta reboot into Windows twice for it to work).
