  1. Have checked Afterburner settings and found that all custom voltage settings were disabled by default so ticking appropriate options and changing skin to v3 made a trick and now I can play with power limit, change core voltage, etc! Thanks for tip, @Dschijn! I have lowered Power limit down to 90%, saved profile settings and run the game to see how it works... First run about 20 minutes - everything stable. What was found that actual GPU power usage is a bit higher then Afterburner settings, so sometimes it jumped up to 103%. Then, I've loaded location where I've experienced crash before and after 5 minutes in game e-GPU shutted down once again, same place, same textures... I've managed to capture Afterburner screenshot just after crash occured, looks like a huge jump in power usage! Now I'm wondering is it something wrong with Afterburner or is it more hardware related?...
  2. Hi Dschijn, I'm using Zotac GTX 970 . Strange thing! I've just spent another hour in Witcher 3 in same location where I've experienced crashes before and today everything is running smooth. No problems... I was keeping MSI Afterburner and GPU-Z in background and made few screenshots of graphs. The only thing that I've noticed is GPU power usage peak that was 113% at some point. Max GPU temperature 78, suppose that is normal. Also, in GPU-Z prevailing PerfCap Reason during game session was Power restriction. It might be a good idea to lower power limit as you advised above, however not sure if it is a case, since this time game was running stable in same locations without any adjustments... Will keep monitoring graphs and will post e-GPU behaivor in any further crashes. It is also possible to suspect problem with Dell DA-2. Forgot to mention in previous post that I have power switch button installed in Akitio and after e-GPU failed, I was not able to start it by switching power button on and off and had to unplug DA-2 adaptor from socket in order to get yellow/green light indication back. Hi davidexD, Thanks for reply, I've expereinced same crashes both with 361.75 and 364.51 drivers (updated yesterday), not an expert but seems like drivers are not an issue.
  3. Ok, had to bring my first post up since another question appeared after some time of heavy gaming. Hopefully, somebody can give an a bit of help on my issue... After about 60 hours of almost flawless Witcher 3 gameplay using both Optimus mode and External display have experienced several consecutive e-GPU crashes obviously caused by power failure, since Dell DA-2 adaptor led is not showing any light indication after crash. In order to restart Akitio box have to unplug it from 220V socket and plug it again. Then, reboot Windows and everything works OK. I didn't make any diagnostic yet since not sure where to start from but what was found, all crashes happened in different locations but with similar textures prevailing on screen which are looking very similar to haze. Attached screenshot was made just a moment before crash occured and upon restarting from saved game, another crash happened just on the same scene. I haven't overclocked or changed any stock settings, the only alteration was made is custom e-GPU fan curve which is applied using MSI Afterburner. Akitio box is powered using Dell DA-2 adaptor and self made barrel plug. Any ideas what might be a cause of crashes will be much appreciated! Thanks !
  4. Thank you very much for info ZapCord, very nice to see that you've managed to make it working under Windows 10! In my case I didn't have enough time for testing, since had to leave home for the next month due to work and my goal was to bring with me 100% working e-GPU and avoid re-installing OS and games while abroad. So I've sticked with Win 8.1 for a moment but for sure upon return I will give Win 10 another try. Would be very nice to figure out what is the cause why sometimes Optimus is not working under Windows 10. Any ideas is it something that was fixed recently with latest NVidia drivers or problem is somewhere else? BTW, here is my box. I know, there are a lot of unnecessary stickers on it, but that was done on purpose to avoid questions like "what is that black box with plenty wires" when passing security checks at the airports. However, looks like that didn't help much since had to pass separate check at Frankfurt yesterday when Akitio was placed on X-Ray scan's belt. Not sure if it's worth to make a separate post for it, since it is not brining anything innovative to already well described guides from pioneers of DIY e-GPUs, but anyway I would like to give a huge thanks to Dschijn, HammerFET and other folks on this forum for posting their builds and answering my often silly questions during assembling.
  5. Just finished assembling my build couple of days ago and also didn't manage to run e-GPU on internal display using Windows 10. Downgrade to 8.1 fixed problem with first boot! 15" MBPr (2014) + Akitio box + Zotac GTX 970.
  6. That's correct Dschijn, both Iris and GTX can be seen in device manager. Did a bit of search on forum, looks like Optimus is not working properly with Win 10, at least for now... So I would guess downgrading to Win 8.1 wil solve that issue? Cannot test with external display for a moment, do not have any. Thanks for info ! ?? It is running well for me as well, but only with Iris, e-GPU is not active during tests and gaming...
  7. Hi all, Just finished assembling Zotac GTX 970 e-GPU build based on Akitio Thunder2 box and have tried to test it with internal display using Optimus and Windows 10. It seems like GTX 970 is recognized by Windows and starting without any problems, however when I'm running 3DMax Firestrike benchmark performance is very poor and I've got only 1347 scores just like using Intel Iris graphics. Here is a link for my recent results: http://www.3dmark.com/3dm/10641833 And my spec is as follow: MBPr 15" (Mid 2014) Intel Iris only + Zotac GTX 970 + Akitio Thunder 2 Win 10 (Latest updates) and NVidia drivers ver.: 361.75 Any ideas what might be wrong? Thanks in advance and apologize if that question was already asked.
  8. Hi Phantron, As far as I understand Windows is not your primary OS? In Evo*'s guide there is step which will set Windows 8.1 to boot automatically during start up. Does it mean that it is possible to skip this step and keep OS X as a main OS and initiate Windows only for lets say for gaming?
  9. Hi Phantron, That's sounds like something is not starting in correct sequence?... Your finding will be much appreciated. Still waiting for parts in order to begin assembling my AKiTiO based system, so cannot share any experience with you for the moment.
  10. It looks like assembling barrel plug will be first option for me, as far as I understand from various posts, all extended powdered risers are just too big in order to keep all parts inside and be able to close the box. Thanks for the info @Dschijn.
  11. Thanks for reply @Dschijn, have read both posts. Procedures are more or less clear now how to do it without extended riser, however do you know if making modification to internal PCIe board may affect stability or both methods are equivalent?
  12. Hi all, Trying to figure out what parts I need in order to setup e-GPU based on AKiTiO Thunder 2 PCIe box, this forums helps a lot. However, still not certain what problems I might encounter running system without 16x powered riser. My main goal is to keep all parts and cables except PSU inside the box for mobility purpose. Any help will be much appreciated.
  13. Hello Phantron, Your setup looks very promising in terms of mobility. Looking forward to extend my mid 2014 rMBP 15" Iris Pro only with e-GPU based on your guide since portable and durable system is my priority. Can you please confirm if you had any problems running it using Internal Display only? Thanks!
