Kr4nG Posted February 19, 2016 Share Posted February 19, 2016 I just had a huge problem updating the web drivers. After it wanted me to restart my mac os wouldnt load. Once loaded it was stuck in the tiny mode again. Like 4 K resolution on my display. After 3 hours of messing around i disabled the csrutil command again and it seemed like it started working back to normal. Is the csrutil command suppose to be enabled or should i leave it disabled. I tried to enable it and it broke the computer again. Left it at 4k resolution and it seemed like my intel cpu was not being detected. I can explain in detail what i did to fix it but it would take a while. Simple answer is to leave it disabled for me or else it wont work after the nvidia update that was just released.

Kr4nG Posted February 19, 2016 Share Posted February 19, 2016 Let me add that the diable monitor app resolved the border issue i had. I only need the app when i use egpu in clam mode. Also, when using the egpu in mac osx i cant let the mac sleep or else it would cause a crash. Any fix to this? I remember it would sleep without a crash only like 2 times. Do I need to plug in the tb cable into the slot closest to the usb or closest to the mag connector. Do i leave the "automatic gpu switching to save battery" checked on or off.

allancavenz Posted February 21, 2016 Share Posted February 21, 2016 (edited) Hey guys, Anyone have benchmarks from 3dmark for an akitio thunder2 egpu using a gtx980 ti (or even a titan x)? Just looking to see how much of a step up in performance it will give me from my gtx 970 thunder2 egpu. Couple stats from my existing setup below: http://www.3dmark.com/sd/3791173 http://www.3dmark.com/fs/7548370 Thanks a heap!

hongi Posted February 21, 2016 Share Posted February 21, 2016 I have Akitio2 + GTX 970 + DA 220w It connects to MBPr Mid 2014 with GT750m I got one problem with this DA 220W but don't know how or what is wrong with my set up. Here is the pic of my wiring https://dl2.pushbulletusercontent.com/xne6bghnrJe2oMaAEzZobDqcN3ZhvCd6/20160220_230246.jpg When i plug just only the power of the Akitio, all the lighting came on but when i plug both 6 pin to the GTX970, everything just stop. The green light on the power supply also gone. What is wrong with my set up? Any comment? I followed this guide Quote Link to comment Share on other sites More sharing options...
Dschijn Posted February 21, 2016 Share Posted February 21, 2016 (edited) @allancavenz I upgraded to an GTX980Ti a week ago, can do some benchmarks later and post them here. @hongi Are you 100% sure you are matching the correct pinout of the DA-2? ground 3x on the upper side and 12V 3x on the lower side.

allancavenz Posted February 21, 2016 Share Posted February 21, 2016 @Dschijn Thanks for that! Same CPU as I've got so it's a good comparison. It's about where I thought it would be for the firestrike result but your result for skydiver was strangely low? The firestrike score is the one that counts anyway though. I'll have to put a few pennys aside for 980 ti upgrade sometime in the near future I think. Quote Link to comment Share on other sites More sharing options...

--Alex Posted February 22, 2016 Share Posted February 22, 2016 Hi, I'm a new member here. I just built an EVGA TitanX + AKiTiO Thunder 2 + 1000W power supply system, and have it up and running on my 2013 Mac Book Pro & thunderbolt display. I spent a few hours figuring out power supply wiring and bending open the AKiTiO case. I used C clamps to helped flatten the bent section out, but it is still not very pretty. At least the external enclosure fits. As far as benchmarks, the octane benchmark gave me score of 127 for the Titan X alone , and a score of 139 for the GT 750M + GTX TITAN X. The basic guide was incredibly helpful, along with 2 other guides: The automate eGPU script https://github.com/goalque/automate-eGPU and How to compile tensorflow with CUDA support on OSX https://medium.com/@fabmilo/how-to-compile-tensorflow-with-cuda-support-on-osx-fd27108e27e1#.aggzip20a 1 Quote Link to comment Share on other sites More sharing options...

Tensor flow, and caffe are for machine learning. Working with convolution networks on a mac is a good reason for an eGPU. BTW: The caffe benchmarks on my system are equivalent or better than using Nvidia K20s.

--Alex Posted February 23, 2016 Share Posted February 23, 2016 One more helpful hint: I discovered that I had power issues because of my UPS. I was using a Cyberpower 390W that was just fine for my MacBook, monitor and external devices. Not quite good enough for the eGPU setup. Luckily, running the caffe cifar10 full training dataset exposed a shutdown message for loss of power. Does anyone have any ideas how to increase the airflow in the AKiTiO enclosure? It was extremely hot running some tests, the ports on the GPU were hot to touch and I had to take the external enclosure off. Quote Link to comment Share on other sites More sharing options...
allancavenz Posted February 24, 2016 Share Posted February 24, 2016 @Dschijn Thanks for running that again. Interesting seeing the 980ti running as an eGPU versus the other stats in 3dmarks' results for desktop PCs. Obviously the CPU on a laptop like ours is a limiting factor but desktop PCs are getting up to almost double the performance in that benchmark with a single 980ti - http://www.3dmark.com/sd/3459668 I guess there's a limit on the ability of thunderbolt2 - think it needs more like 30gbps rather than the 20gbps available. Obviously thunder 3 is heading this way, but makes me think a hackintosh desktop might be my next move for 4k multi monitor if I ever do that.

I just think the 20gbps of thunder2 might not quite be enough when getting up to a card like that. Still an awesome setup as an egpu though. Just pondering on what to do for a nice 4k multi monitor rig in future. Quote Link to comment Share on other sites More sharing options...
DannyFK Posted February 24, 2016 Share Posted February 24, 2016 Hi to everybody again, Some weeks ago I wrote this: "Hi to everybody. I made my own eGPU using an external PSU. With the goalque script I got on all the system in OS X, but I'd like to use on Windows because I heard that the performance can improve. I have a problem because my system on Windows 10 (Bootcamp installation) recognize the eGPU but it's unable to use (code 12). It attempts to connect to the external display but the Windows logo freezes and turns to the internal display using the dGPU (Geforce 650M). I realize that Windows don't recognize the Intel 4000 HD Graphics. My Mac specs are: - 2012 MacbookPro Retina mid 2012 - 16 GB RAM. - iGPU Intel 4000 HD Graphics. - dGPU Geforce 650M. Somebody could help me? The second issue is that using the DELL DA2 power source when I am using the eGPU on OS X during some minutes, it shut down and the system crashes. I suppose that it could be a electrical power up issue. What do you think? Thanks to everybody in advance. Danny." Please somebody can help me? THANKS A LOT.

DannyFK Posted February 24, 2016 Share Posted February 24, 2016 (edited) Now I am powering with an external PSU that works fine. I mean, using Mac OS X I have no problems. The problem is when I try to use it on Windows 10. I made the partition on the hard drive and it looks like to work, but the Windows logo screen freezes on the external display and then return to the Mac screen. In the device manager I can see that the eGPU, but it indicates code 12. I installed the latest drivers for Windows but it continuing with the code 12. I have MacBook Pro Retina mid 2012 with 16 GB and i7. iGPU: Intel HD 4000 and dGPU GeForce 650M. I have to do something else apart of configuring the hardware, starting as you indicates Windows with the eGPU and install the NVIDIA drivers? Thanks.

sgrit Posted March 3, 2016 Share Posted March 3, 2016 (edited) Dear TechInferno forum members, I have a MBP (17-inch, Mid 2010) with an i7 2,66 Ghz Arrandale processor and my built-in graphics chip GT 330M is fried. In my current situation I can use the integrated HD Graphics (using "gfxCardStatus") but it doesn't need a lot of explaining that my performance is limited somewhat. My question is if it is possible to use an eGPU with my laptop using the ExpressCard/34 that my MacBook Pro is equipped with (it sadly lacks Thunderbolt ports). I would like to use it (mainly) in my Bootcamp setup, but using it in OS X would be a serious boon. Does anybody have experiences with a similar model, or has heard of cases where it was done? And if so, what are your/their experiences? Kind regards, and thanks for any help, Stefan Edited March 3, 2016 by sgrit Quote Link to comment Share on other sites More sharing options...

kblack21 Posted March 4, 2016 Share Posted March 4, 2016 @valix2fr I saw your issue and it seems similar to mine. I've traded in 2 gpu's and 2 psu's (Though I don't regret getting the evga 500 PSU to replace my Corsair, it is so much better) but I still kept getting no device detected. So I Bit the bullet and got another Akitio, and that solved my problem. Still i'm kind of inquisitive and didn't see what was wrong with my original Akitio, so I by chance tried pulling the board out the enclosure. What I found was that the chip with the thunderbolt ports was a little loose from the chip with the PCI E slot (Posibly from when I altered the box for my Titan), so I disconnected them and reconnected them. Then I tried the old Akitio again for kicks, and it worked perfectly. So i'm not sure if you messed with your Akitio, but it's worth giving this a shot. 1 Quote Link to comment Share on other sites More sharing options...
