I have a frequent issue while booting with my eGPU (GTX 980 on a Macbook Pro 2012, Windows 10). I am using DIY eGPU setup 1.20 to get rid of my code 12 error. This means I need to access my boot manager every time I boot, chose setup 1.20 and finally option one. And that's the tricky part: 20 % of the times I boot I don't even get to my boot manager. My macbook just boots normally, and thus my eGPU won't work. 60 % of the times my external monitor (connected to my eGPU) shows the boot manager. If I chose eGPU setup and try the automated startup .bat-file the system just freeze. 40 % of the times I get the boot manager to show up on my macbook, and then it works perfectly. So, how do I get boot manager to always show on my macbook?

Oh so that is the boot menu I'm supposed to access? I thought it was some sort of bootloader/BIOS were I had to press F8 (which doesn't seem to work on my computer). Alright, I'll give it a shot, thank you for all your help

Alright thanks, I think I can manage that. However, I don't understand how I'm supposed to access the boot menu in order to run Setup 1.x. I thought I would need BIOS for that? I am confused, Device manager tells me I'm running Master Boot Record (MBR) but I thought Macs were using UEFI?

Alright thanks, I am glad to hear that However now I have no idea what the trouble might be. Yeah I think I have everything connected correctly: I am using a 500 W PSU that seems to power my Akitio box correctly (even tho I had to use power from 4 Pin Peripheral instead of the 6/8 pin PCI-E that was recommended, since my GPU takes up my 2x8 PCI-E slots). I have fan movement on both my PSU, GPU and Akitio box. However I have to use a PCI-riser, since my GPU doesnt fit inside the case. The riser is also powered via a 4 Pin Molex. When I plugged in my GPU the first time I had to manually download the drivers in order for my GTX 980 to show up (with a code 12 error). Seconds after that my mouse pad stopped working and the computer started making multiple, short beep-sounds every time I tried to use it. Rebooting computer didn't work. Any idea what the problem might be? Feel free to ask if you need more info Cheers

Can someone please help me troubleshoot this? I've payed a little too much for someting that currently doesn't work

Hi friends, I am new to this forum and unexperienced with eGPUs, so I apologise in advance for any wierd/stupid questions I might ask. Here is a list of what I'm running: Computer: Macbook Pro Retina, from 2012 CPU: i7-3820QM @ 2.7-3.7 GHz dGPU: Nvidia GT650M RAM: 16 GB OS: Windows 8.1, via Bootcamp Thunderbolt connection: 2xThunderbolt v.1 As eGPU I chose MSI GTX 980 Gaming 4G together with AKiTiO Thunder2 PCIe Box. And now, the reason I made this thread: I installed my eGPU today and encountered some software issues(?), more specifically a code 12 error that seems to be rather usual. My question is if this has anything to do with my TOLUD being >3.25 GB? I tried using the guides posted on this forum to check my TOLUD, but my Device Manager seems to differ a bit from yours. I would be grateful is someone could take a look on my pictures and tell me my TOLUD value. Secondly, if what I described above is the cause of my problem, can I fix it using the DSDT override that has been described on this forum? I found the made by Kizwan. Can I follow his procedure thoroughly to get it to work on my setup?Thank you, A confused Red Onion
