IT WORKS. GT650m and GTX 560 Ti both working in Device Manager. Now if only I can remember how... 

 

So I think after the DSDT override I ran PCI compaction, 56.25GB endpoint, but targeting only eGPU+dGPU, then when asked to force a GPU to 32bit, I picked the eGPU. Previously I was running compaction on "ALL except (sata, etc etc)" which was the recommended setting I'd seen in previous Macbook guides.

 

Am now scared to reboot.

Congrats, @r00x. Now it seems easier to use your eGPU, isnt it?

Frustrated as I am, I cant get it to work. I might need to format again and start from scratch. 

If you could list out your step by step guide, that would be helpful. Or you had follow the same procedure that farandhigh98 given, then that's ok.

Hey, I made my mid-2012 setup a few weeks back, and I had the same problem...I think.

 

That instruction is what I initially did to solve the problem; but every time I installed driver again (the 980Ti driver) it would automatically get 650m again.

 

I did a DSDT override, and it worked; take a look at the link below!

 

 

I hope it works for you.

Hi @farandhigh98,

I have try to follow the link you shared it but I haven't try out the results yet.

Were you able to get the same results as shown? I can't find the PCI bus last entry but only PCI complex roots. 

And also I wasnt able to get LARGE memory from device manager > resources by connection. 

I'll post another update if I was able to get it to work or failed again. I dont have the time to do any eGPU test for a while.

If you can see the card in Device Manager that's good news. Hmm, it shows as Microsoft Basic Display Adapter - usually at this point it's a case of getting the drivers installed for the eGPU, I think?

 

Once you disabled the GT650m, did you restart?

 

Have you installed up-to-date drivers from NVIDIA? The default Microsoft ones might not be good enough (I might be wrong, but I think the error you describe is it complaining that it expected to work only with a mobile GPU?).

 

Maybe try this:

• Download latest NVIDIA drivers from their site (use your eGPU when they ask what card it's for)
• Then uninstall your existing drivers (from Programs and Features, not device manager)
• Then try to limit Windows automatic driver downloads (go to your System Properties (right click in bottom-left corner of screen and click System), then Hardware tab, then Device Installation Settings and set it to "No".)
• Then restart
• Then install the new drivers you downloaded (use the clean installation option). It should, ideally, show both GPUs now, but the eGPU will have an error  (maybe 43, like with mine)
• Then disable your gt650m and restart - ideally now your eGPU will pop into life! You do need an external monitor plugged into the eGPU and turned on, I think.

 

 

 

Hi @r00x,

Yes, I did restart after disabling the GT650M. And updated the lastest nvidia driver. In no specific order

I followed your instruction but I start off:

• Plug in eGPU , disable GT 650M, Reboot
• Download latest NVIDIA drivers (specifically my eGPU)
• Uninstall just the nvidia graphics driver through Programs and Features
• Limit Windows Automatic Driver.
• Reboot
• Install drivers

And this happens. Once the drivers install, external monitor did went on but it show a black screen and a wifi symbol glitch on and off?

Still no luck. Oh and I went back installing Setup 1.2 for good measures.

Hi,

A little update. I followed @errin guide with every step of the way. Still no result. No detection of eGPU in windows 8.1 . 

Later, I installed DIY Setup 1.3. Giving me a chainloading error.

I'm really getting frustrated here. Am I really out of options here? Can someone give me a very specific guide whether I should do or dont?

Hi Kazeki, what switch settings have you used on the PE4C? I have the exact same laptop (assuming you have Retina model? Anyway not much different except for screen really) and I've found it worked best with SW1 set to "2" and SW2 set to "1". 

 

Set up like that, I can get eGPU running in OS X or Windows with no hotplugging required.

 

However for me, to get eGPU to work in Windows, I did have to first open Device Manager and disable the GT650m. If I do that, then restart, the eGPU works and you can still use the normal laptop display (but you might need to reset the resolution and scaling, and it won't be hardware accelerated like the external monitor).

 

eGPU setup 1.20 didn't seem to work for me, it made no difference using PCI compaction so I actually don't use it at all - as long as I disable the GT650m in device manager, the eGPU works, and this is good enough for playing games on an external monitor. eGPU setup 1.30 couldn't even complete PCI compaction without hanging/crashing.

 

If I don't disable the GT650m then Device Manager will show the eGPU is detected but it says Code 43 error.

 

Hope this helps!! Also let me know if eGPU setup worked for you and you somehow can have the GT650m AND the eGPU running because I'd love to know how to do that.

Hi @r00x,

Thanks for helping. Setting the PE4C SW1 and SW2 worked. Save me the hassle to hotplugging. But unfortunately disable my GT650M did not help at all. Still wont able to detect my eGPU.

I'm not too sure if my thunderbolt needs to be updated or not but it works with other PCI-express hardware. 

I have no error code so which mean I did not progress at all.

Yes. Ruining mobile and desktop drivers simultaneously has led to error 43. Revert to just the desktop driver.

 

Pci.bat needs to be edited as explained at the following amongst most MBR egpu implementations for your system. Did you not see and therefore not do this important step? 

 

Hi @Tech Inferno Fan,

Thanks for helping. The link you sent ,user bsohn, did help me a little bit. I dont know how but the eGPU setup 1.2 did detect my GPU or looks like it but when following the steps froze or stays when choosing an option (mind you, i press the number keys instead of anything else) . Im still stuck with my computer not detecting a gpu or giving me an error like everyone else. I need to try again. 

Bottom images are something new that happened. Probably isnt important.

Hi,

I have a big/little problem to make my eGPU work.

Here's are my specs and hardware.

Macbook Pro 15" Mid 2012

2.6GHz quad-core Intel Core i7 processor (Turbo Boost up to 3.6GHz) with 6MB L3 cache

8GB of 1600MHz DDR3 memory

1TB Seagate SSHD + 750GB 5400 rpm (optical disc drive removed)

NVIDIA GeForce GT 650M with 1GB of GDDR5 memory

OS: OSX Yosemite & Bootcamp (Windows 8.1 64-bit)

eGPU needed hardware/software:

480W PSU Veriton

Sonnet EE

PE4C-EC060A v3.0 (Link to website: http://www.hwtools.net/Adapter/PE4C%20V3.0.html )

QLeadtek GTX 650 Ti Boost

DIY eGPU Setup 1.20 by Tech Inferno Fan

So,

I already have bootcamp(Windows 8.1) installed. So skip that part.

Installed the DIY eGPU 1.20 (Have read throught MBR implementation, it seems my model requires 1.20 since everyone is using it?)

Hook up the hardware. Image below shown. Ok. I cant upload a 189kb picture. This sucks.

I hooked up the 24 pin from PSU to the eGPU. And use a 2 molex adapter to a 8 pin connector to power my GPU. Then eGPU express card to my Sonnet and to my laptop.

Situation:

eGPU and GPU works when I on my laptop. That's fine.

Problem 1:

Whenever I do that in the beginning, my computer freezes. Before my mac can boot up to windows os, it freezes on the white screen.

Problem 2: 

Run laptop first to boot windows 8.1. Then plug in eGPU. GPU isnt detected. Nothing happened. 

So far this is accurate on what I have been doing with eGPU. I worked on this for more than half a year now. I need help.

I've gone through lots of websites and such. But havent gone through enough.

Please let me know what's my problem or any further information, i'll do my best to answer them.

(Edit1: Planning to buy a swex soon. So its gonna take 1 month time. Not sure if its needed or not)

Thanks,

Kazeki
