Hi guys, I have now a Sonnet expansion chassis with an Titan X connected to a mid 2014 MBP 15" Retina 750m 16GB 2.8Ghz running. The system is rock solid, it is also a lot more stable now as it used to be when I work with cuda accelerated Software. I'm quite happy :-) However, there is a detail that bugs me. When I connect everything and try to power on the system, it straight up won't boot. It stops around the Post I guess, because there is no apple chime, not even the display is turning on. The expansion chassis does though... So I have to turn the Laptop on without eGPU and plug it in as soon as the apple shows up, after the sound. Then it works like a charm. I know, that's probably because of the internal 750m graphics card, but is there a solution since the problem is probably around the EFI boot rom? :-/ I'm all in all pretty happy about the system, yet I just want to try to make it running as smooth as possible. :-) Thanks a lot. Marco

Hi, does it work with DaVinci though? Marco

Yes, but I'd like to keep it as simple as possible. The Sonnet III-D looks like a neat solution and if it runs stable, I could take it on Set as power boost very easily. I will think about that though... ;-)

Tach auch... :-) I'll keep you guys informed about my experience.

Thanks a lot Dschijn, fortunately it's Christmas soon... Greetings to Germany from a Swiss guy in New York. Marco

Hi folks, I'm working in post production, mostly on workstations from others, but sometimes also at home. I sold my old system and bought for the half of my soul a MBP Retina 15" last winter, which is really a beautiful and potential piece of hardware. With its quad core i7 cpu and the 750m GPU, even DaVinci Resolve runs acceptable. Now, I like scalable systems and I kinda got a crush on the idea of using an external GPU to improve my systems capability, so I'd like to build one of them. What do I have: Macbook Pro 15" Retina Mid2014 2.8GHz i7 16GB 1600 Mhz DDR3 1TB Flash drive Intel Iris Pro 1536MB NVIDIA GeForce GT 750M What I'd like to do with the eGPU: MacOS: using the eGPU as render card for Premiere Pro, After Effects and DaVinci Resolve (therefore it's not about using the eGPU for the Retina Display) Windows: play Video games over an external Display, connected directly on the eGPU (Macbook is closed) What is my plan: Sonnet Echo Express III-D expansion chassis NVIDIA GPU You guys are still with me? If so, thanks a lot :-D Now, DaVinci Resolve likes to have plenty of VRAM, so does an ASUS GTX Titan X work in the Sonnet chassis? Just the "standart" version, nothing fancy overclocked... (I know, I'd have to change some cables for the power supply) I'm from the IT Business, so I'm very confident when it comes to computer, yet I have no experience with eGPU's at all. Moreover, I'm still struggling to belief that the TB connection is fast enough, but I found a lot evidence online that shows how potential eGPU's are, so there must be some truth... :-P I've already read a lot about that topic in this awesome Forum, but now I need personal "know-how" from people who are really into this whole topic. I really hope you guys can help me with your thoughts and inputs, maybe I'm on the totally wrong track. Thanks a lot for your time, I appreciate that. Marco Edit:// thanks to the admin for moving my question to the right place. :-)
