13" Lenovo U310 + GTX 750Ti + Win 7 (EXP GDC V8 PCIe) [ReverseEffect]
3dMark11 Performance Preset Benchmark: http://www.3dmark.com/3dm11/11262792
1.) Lenovo u310 (I have a Core i3 - Ivy Bridge, 8GB RAM)
2.) 65CN99WW unwhitelisted. (Had mine removed at bios-mods.com a while back.)
3.) eGPU (I used a EVGA GTX 750 Ti from another computer I had).
4.) EXP GDC mPCIe Edition adapter (got from eBay - banggood seller).
5.) ATX power supply (I used a 600W PSU from another computer I had).
6.) USB wireless.
7.) External monitor, keyboard, and mouse.
1.) Obtain and install a unwhitelisted BIOS. (As I put above, I got mine from bios-mods.com a while back when I was changing out the wireless cards on the computer, they require you to use a BIOS backup that is unique to your system). If you are unable to obtain a unwhitelist BIOS, I think it might be possible to bypass it with nando4's Setup 1.x (may need confirmation as I haven't used it myself yet.)
2.) Shutdown computer and remove all USB devices, ethernet cables, power cables, card reader cards.
3.) Remove mPCIe wireless card and detach antennas.
4.) Attach EXP GDC external mPCIe cable to the former wireless slot and screw down.
5.) Attach HDMI end of the mPCIe cable adapter to the EXP GDC device.
6.) Attach graphics card to the EXP GDC device (I moved my laptop off the desk and onto the side shelf to make room on the desk for the monitor/keyboard/mouse).
7.) Using the power cable adapters that came with the EXP GDC device, I hooked in my ATX power supply's 20 pin and CPU 4 pin cables. Then hooked the other end (8 pin) into the EXP GDC device. My EVGA 750 Ti also required that I use an additional PCIe power cable (6 pin) in the top of the card.
7a.) Connected 20-pin motherboard and CPU 4-pin to adapter.
7b.) Closeup of power adapter (20-pin, 4-pin).
7c.) Overhead of connections and connected 6-pin PCIe additional power for my card.
8.) Then I attached my misc devices (HDMI monitor, USB keyboard/mouse/wireless adapter), and hooked in my PSU and powered it on (below is image of final product, also moved HDMI cable out of the way).
9.) Power on your computer and let it install the standard VGA drivers and then install your drivers (I didn't have to go in the BIOS for any graphics settings, which it doesn't have anyways, nor did I have to disable iGPU in Device Manager before the card was added).
I found that most games will play on med settings with about 45 FPS with this particular card.
BDO: Upscale on - Anti Aliasing on - SSAO off - med settings.
Skyrim: Med-High settings.
Fallout 4: Med settings.

Lenovo T450s NGFF Implementation
I have been trying to get an eGPU implementation working on my T450s. The only option I could find for it is through its NGFF slot, which I think is only 1x speed. I picked up the eGPU adapter from yoybuy: http://www.yoybuy.com/en/Show/40808703110.
The graphics card I am testing with is the Zotac 750ti. When plugged into the T450s before boot, the laptop won't post and gives 2 beeps. It does let me chainload, however I can't seem to get the device to show up in the device manager or in Setup 1.30. It's plugged into the port that the wifi chip was in, so it should support more than just SATA right?
Anyways, NGFF eGPU setups seem like uncharted waters, but if anyone has tried this form factor before, please let me know.
14" Lenovo T420s (working in progress)
First of all, really appreciate this project and I want to thank to all of you guys sharing your experience and creating such a great community.
if there's anybody that managed to do it successfuly on this Thinkpad model, please PM me so I can talk with him, and I promise at the end I will post a full guide for this type of Thinkpad (wasn't able to find more that 2 posts related to this type of Thinkpad, and at one nobody responded, the second one I cannot find it anymore).
I decided to start my own eGPU project, on my Lenovo Thinkpad T420s.
I have waited for the PE4C-EC060A V3.0 ( eGPU PCIe x16 interface for ExpressCard) to be released and decided to order one (since Thinkpad T420s has an Express Card port) but instead I ordered an PE4C version 3.0, PCIe x16 interface for mPICe; Length 60c and it has been shipped. I than opened my laptop and I've noticed I do have a 2nd mPICe slot, and here comes my first question:
1st question: do you guys recommend me in switching to the Express Card version, or the mPICe one behaves the same as the Express Card one? The only inconvenience is that it will be harder to plug it in and out, since I take my laptop to work at a daily bases.
Looking at the requirements, I saw that it is possible to do it for this type of laptop by having a bios version of 1.3x.
2nd question: The bios version of 1.3x refers to the bios versioin developed by @nando4, or just the market one? ( I currently have 1.31 installed).
I than need to consider what GPU to order.
The post that I found about GPU installed on a Thinkpad T420s, it was talking about an Geforce GTX 570 (from what I remember - this is the post that I cannot find anymore) .
I was thinking about buying an GTX 750 Ti OC2 2GB, beeing a 3rd Generation that seems to work with the PE4C V3.0, but while reading the forums, most of the guys installed a 2nd Generetion GPU.
3rd question: Does anyone know if the PE4C v3.0 Gen3 is stable or it';s safer to go with older GPUs.
That's it for know.
Thanks and really appreciate the support.
Lenovo Ideapad y50-70 BIOS Modding (GTX 860m 4GB)
Hey guys, does anyone have the spare time to mod my laptops BIOS so that I can remove the limit of the sliders in MSI Afterburner. So that I can go above a max of 135 on the core, have the voltage and power limit sliders unlocked etc. If it can be done for free, I would much appreciate it, and donate in the future when I get some money. If you can do the task, plz reply and I'll upload my BIOS backup to RGhost if that's the site you guys upload stuff to on this forum. Thanks in advance friends!
