Gaming Laptop build with GTX750ti-LP (Non-eGPU)

So I'm a recently father of 1 and struggling military personnel. No need for more details. I'm building a "gaming desktop" out of parts I'm collecting out of other people's trash basically. Running on all 2012 standards. currently I'm using a AMD Athlon II x4 clocked at 2.6 GHz on a Pegatron M2N78-LA (Violet6) motherboard with 500Gb of space and a Zotac Nvidia GT 640. I'm really proud of this setup so far because the overall price of the desktop is currently sitting at $10 for the Arctic Silver to replace the old thermal paste. The main thing I'm wanting to know from this community is whether or not the AMD Phenom is a decent processor. On paper it looks fine, but i have never built with it before, therefore I'm uncertain. Also if anyone knows of a cheap cheap MOBO that is still high quality and has 4 DIMM slots and preferably at least AM3+.

In case you own a Lenovo Y410p or Y510p laptop, you might be interested in upgrading its performance by installing an external graphics card. Ultrabay eGPU adapter designed by @gerald was proven to be a convenient plug-and-play option to do exactly that. However, for a long time only an AMD-branded GPUs could be used due to limitations in the Lenovo's stock BIOS. The purpose of the modified firmware presented here is to expand the range of available GPUs by enabling Nvidia support on Gerald's Ultrabay eGPU adapter.
 
Huge thanks to:
@MWichni - For efficiently assisting me during the development of this mod. By flashing dozens of BIOS builds over the course of several weeks and thoroughly describing the effects observed (or the lack thereof), he enabled me to fully understand necessary parts in BIOS structure and come up with a final solution. @svl7 - Whose unlocked BIOS / Whitelist mod has served as a basis for this modification. His discovery of a security hole in V2.07 BIOS has provided us with a convenient BIOS flashing method that does not require a physical programmer. The Unlocked BIOS and WLAN whitelist mods originally designed by him are also implemented in this BIOS mod. @gerald - For designing the aforementioned adapter. Without it, all this work would make very little sense.  
Key features:
Resolves the "40-second reboot" issue normally encountered while using Nvidia graphics cards with Ultrabay eGPU adapter, thus allowing all Nvidia cards to be used. Based on the latest V3.08 BIOS. Includes Svl7's WLAN whitelist removal mod - for the convenience of aftermarket WLAN card users. Includes Svl7's BIOS debug menu mod - for the ease of experimentation with newly available features, e.g. attempting to use Nvidia Optimus to pass eGPU video back to laptop's display.  
NB! Svl7's Debug Menu is not a toy! It contains a lot of options that are either not supported or partially supported by the hardware platform and/or can disturb its normal operation or prevent the PC from booting up at all. Any of the entries not originally present in the stock BIOS should be modified at your own risk!

If things don't go right:
 
Error 43:
If you intend using the GTX10XX-series Nvidia card as the eGPU (which you probably do), you are very likely to encounter the infamous Error 43 in Windows Device Manager. This is a widely known issue in the eGPU community and is not related to this particular mod in any way. Following this guide thoroughly will in most cases resolve the Error 43 issue.

Version of this mod for Lenovo Y400/Y500 models is coming soon!
 

Hello, I need help trying to put my setup to work. I recently purchased an Akitio Thunder 2 with a GTX 1050 ti Superclocked to implement it as an eGPU for my system. I have a Macbook Pro 15” mid 2012. I’m not interested in using it with OS X (I’ve read that there is not much support by Apple for Nvidia cards Series 10). My main goal is to use it using Windows 8.1. I had some trouble with the initial connection as Windows recognized the external card but it gave me error code 12. I already got rid of the error 12 problem. The situation now is that I connected a second display through the HDMI port of the eGPU and activated it using the Nvidia Control Panel. After a restart I choose to boot windows 8.1 again but the two displays get hanged with black screens and I only see the cursor. Anybody has had this problem and was able to fix it?
 
I did some further testing, decided to boot up with the eGPU connected but without the HDMI cable plugged. I was able to log in to Windows and the eGPU got recognized in device manager, but then I connected the HDMI cable and for one second I saw my Macbook screen displayed in the external monitor, then both screens hanged again with black screens only showing the cursor. I’m exhausted of experimenting and seeing no positive results...
 
My goal is to be able to use the eGPU with the internal monitor of the Macbook (if that is possible with my system). If not, I would like to know how I can set it to work with a second display. I will be very grateful if somebody can help me... Sorry for the long post.
 
 

Hi, Masters,
 
i m trying to let my egpu working through modding the inf file.
My 660ti's device number is this
PCI\VEN_10DE&DEV_1183&SUBSYS_2843 1462&REV_A1 and i manged to add a few lines in the nvlti.inf file, cause my laptop is thinkpad...
i m not sure if i should mod this file or others either way it didnt work.
i added line below
[NVIDIA_Devices.NTamd64.10.0...14310] ... %NVIDIA_DEV.1183.2843.1462% = Section021, PCI\VEN_10DE&DEV_1183&SUBSYS_28431462 %NVIDIA_DEV.1183.2843.1462% = Section022, PCI\VEN_10DE&DEV_1183&SUBSYS_28431462 [Strings] ... NVIDIA_DEV.1183.2843.1462 = "NVIDIA GeForce GTX 660 Ti" for some unknown reason it just didnt work........
Could you guys help me out,
