Hey guys After about a year of testing, experimenting and finishing up my build, I decided to put my setup on display here. I'm pretty happy with how it turned out. Specifications of my current setup: Machine: MacBook Pro 15" (mid 2014) CPU: Intel Core i7 4780HQ @ 2.5GHz RAM: 16GB Storage: 512GB SSD OS: Windows 10 Pro (x64) and OS X Yosemite 10.10.5 E-GPU: Akitio Thunder2 Case: Coolermaster Elite 130 PSU: Corsair RM450 GPU: EVGA GTX960 4GB SuperSC ACX 2.0+ External monitor: Dell U2913WM Ultra wide-screen monitor Setting up the hardware: In the early stages of my build, I used a powered riser. Back then it was recommended. However, it quickly became clear that it was a cause for stability issues, so I removed the riser from my build and made a molex-to-barrel adapter from the plug that came with the Akitio. I also drilled some holes into the case so I could mount the Akitio circuit board into the case like you would do with a motherboard. I wasn't pleased with the result however, because the card didn't have enough support for its weight. So I cut off the back of the Akitio inner-case so my card would fit inside the enclosure. I mounted the circuit board back into the inner-case, and screwed the inner-case into the mounting holes of the case I drilled. To turn on the E-GPU setup, I also mounted a latching vandal switch at the front of the case that is hooked up to the PSU. This allows to easily turn on/off the system. Setting up the software: There was not much to this, actually. This version of the MacBook pro (the ones with dedicated GPU) hardly experience any problems with the installation. For Windows 8.1 and 10 (having them installed in EFI mode), it immediately detected the presence of the extra GPU and was as simple as installing the correct NVIDIA drivers again. For OS X, I used the script from @goalque to make it work, which is very neatly and easily done. Issues: I faced some issues while I experimenting and playing with the setup. My initial setup used a Gigabyte GTX770 4GB, which seemed to crash rather randomly. I had the same problem with a Gigabyte GTX760. These cards, however, were factory overclocked, and clocking them back to the default specifications from NVIDIA somewhat lessened the problem. But I never experienced these issues when using older cards (GTX560 and GTX460). So I assume it was either something with the 700-series, or manufacturer related. The card I use right now, the EVGA GTX960, doesn't have any of these stability issues. The only problem I still face right now, is the black boot screen without booting chime. I can see my USB-devices starting up (blinking lights, LED displays turning on), but it doesn't get further than that. I need to do a hard shutdown of the system by holding down the power button, hoping to have better luck next time I turn it on. However, this doesn't cause any stability issues once the system finally gets past the boot chime. Credits: I would like to sincerely thank this entire community for making this possible. Your dedication and experimentation to making this work is something that I admire and appreciate. I believe this setup is the most ideal one and most convenient to use in my daily life: good system on the go for work, best system at home to game!

For those who don't like the restrictions Lenovo put on their system, here's a BIOS mod that will get you back at least some of the freedom you should have over your own hardware. Features: WLAN card whitelist removed, any (hardware-wise compatible) card should now work hidden BIOS menus unlocked VBIOS tweaked for more performance and better tuning possibilities Keep in mind that not necessarily all of the BIOS options available with this mod will be fully functional, so use the new available settings with care. If you're unsure about something don't change it and ask here, someone might be able to help. Available for v1.07 / v1.09 / v1.10 and v3.05. v2.04 and v2.07 added (only whitelist removal as for now) If you have a different BIOS (or more specific, a BIOS newer than 3.05) I will need a copy of it in order to make it work for your system. Instructions for flashing the modified BIOS v3.05: You need a USB stick prepared to run DOS, here is a guide you can follow in case you don't know how to do this: Guide by @StamatisX - thanks! >>> Before continuing make sure the AC adapter is connected to your laptop and your battery has at least 20% charge remaining. <<< (0) - NOTE: This step is Only necessary if your system isn't already using BIOS v3.05 Update to the official v3.05 BIOS provided by Lenovo . (1) - Create a backup of your own BIOS (now v3.05) by using Fptw64 tool. Extract the files and run the included .bat file from an admin command prompt. . (2) - Download Lenovo_Y510p-Y410p_[v3.05]_modified.zip and put the files of folder [1] to the root of your prepared USB DOS stick. Let the BiosFixer prepare your BIOS for flashing by drag and dropping your backup file on it. Put the created "v305mod.bin" file to the root of your USB DOS drive as well. . (3) - Now you need to downgrade the firmware back to v2.07 (Y510p-Y410p_v207_[stock].zip) in order to flash the mod. . (4) - Boot from your USB DOS drive, when you see the command prompt type BIOS and hit enter. Wait until the BIOS is flashed (you can safely ignore warnings about non-existing regions). . (5) - Once the BIOS flash completed with no errors, type EC and hit enter. Wait until the EC is flashed. Then reboot. . (6) - Go to the BIOS setup menu, load the default settings, apply and reboot. Done. In case you're using an ultra bay GPU follow the instructions in post #2 and flash the vbios.. NOTE: It's crucial that you flash both, BIOS and EC. Having different EC and BIOS versions can in certain situations lead to issues. IMPORTANT: If you want to go back to stock v3.05 you can do that easily by simply using the official update from Lenovo. That's it, nothing additional required in this case. Old instructions for users with v1.07 / v1.09 / v1.10 or v2.04 / v2.07 who for some reasons don't want to update to v3.05: Video walk-through of bios settings (thanks @allstone): My donation link in case you want to buy me a beer Download link for files referenced in this post:

Install GFE to update all profiles, once updated...uninstall GFE ASAP... - - - Updated - - - [MENTION=1756]twin snakes[/MENTION] even v352.86 is not safe...if you stick to win10 then don't switch graphics or enable/disable SLI *whatsoever*. [MENTION=2750]Miguel Maroto Madrid[/MENTION] like twin snakes update profiles using GFE.

Did not know about the option settings, but 1080p is still the highest available, thought it did show a bunch more (all <=1600x900). I'll look into SwitchResX. Thanks for being so attentive and helpful!

Perfect!! installed GeForce 355.83 drivers in my m18x r1 with w7 and working fine, but still is not possible change to integrated graphic card... may be is not a mod drivers problem.

my question is are the latest drivers for 8.1 safe to use? i also have an AUO panel that i can spare for those testing win 10 on the AW17 R1. will send if there's a person willing to pay for the shipping.

6870OD1.1v.rom.zipAfter i tried to mod my 5870's to FirePro M ended up with a different project, however i not given up just jet... But the project revealed something for me so i thought why not give it a try???? So here i ended up AMD 6870M CrossfireX with a fancy Overdrive Support in it 860/1200Mhz at 1.05v Used different methods to unlock that, (BAGZZlash's RBE ) and HexWorkshop v6 to peace it together... New ver 2 oc'd 800/1100Mhz 1.1v OD up to 860/1200Mhz 1.1v [ATTACH=CONFIG]1810[/ATTACH] Here if you need it, or want to give it a try...
