What I do for my T430 is just suspend on windows, plug in the express card then power the eGPU and unsuspend If you disable the internal screen your iGPU will stop working which means your CPU will run much cooler. My CPU temps are lower when I play The Witcher 3 on high with my eGPU on (it's not even a quadcore, crazy.) than when I idle on chrome with my eGPU plugged out because the iGPU is running. Sometimes I enable the internal screen so I can stream with OBS and encode with quicksync (intel iGPU) and it still keeps the temps pretty low since the game runs on the eGPU

I have a 7850 on a T430. In GPU-Z try clicking the ? on the right of the PCIe speed, mine throttles to 1.2x as soon as it gets under load.

Updating as my PE4C v2 arrived yesterday. I had already done a DSDT override from my previous post, I have a T430 with no dGPU and a i3320M i5. As soon as it arrived I slapped my 7850 on it, powered it up with the Dell brick that came together with it, suspended my Windows 7, connected it and turned it on. Windows recognized it instantly and downloaded it's drivers. Then I downloaded the latest stable AMD CCC and installed it and everything worked out of the box. I had output on both my laptop screen and my DVI connected to the 7850 monitor working perfectly in extended mode without having to do anything, I honestly don't know if what's on my laptop's screen comes from the HD4000 or the ATI card but I can freely move a windowed game between the two seamlessly. GPU-Z says that the connection is at x1 1.0 but as soon as I start the render test or a game it kicks up to x1 2.0 and stays like that.

I really suck at explaining but I think the best way to go at it is this one. Use the iasl.exe to dump the table and decompile it. Add the QWordMemory part and compile it. If loading the table with asl /loadtable doesn't work then do the following. Take the .aml file that came out of iasl.exe and take it to the folder with asl.exe (The version that I linked worked for me, the one in WDK 8.1 did not.) Decompile that file with asl /u filename Rename that file into something else and open it with your editor of choice. Now dump your DSDT table with asl /tab=DSDT This makes another asl file, open it up with your editor. Get to Device(PCI0) in both and compare the two buffers. The one that you disassembled from iasl.exe should have differences like the one I posted (First line and last few lines) Since you added the 32 bit allocation with QWordMemory. Pretty much copy the buffer from the iasl.exe decompiled ASL to the asl.exe dumped ASL. Save, run asl filename (The one you just saved of course.) This compiles, it gave me a few errors for a method which I commented/deleted out. Loaded it with /loadtable and now I have my large memory thingie. I haven't gotten my PCI adaptor yet but I will test it soon. It is of course not recommended to just delete something out of your table to make it compile so you might find another workaround for that.

I managed to DSDT override my T430 with some black magic and luck. First of all I updated the BIOS, something I had not done yet since I had the second most recent and I don't know if this alone does the trick but it might and in this case I'm an idiot and wasted way too much time.

As per my post here: http://forum.techinferno.com/diy-e-gpu-projects/3539-guide-dsdt-override-simultaneous-igpu-dgpu-egpu-7.html#post104586 I'm having problems DSDT overriding on my T430 with Windows 7, no dGPU and Ivy Bridge i5, 3.5gb TOLUD. I really want to get this eGPU setup to work but I'm not so sure about my options right now. I'm thinking of purchasing a PE4C V2.0 as that would work with my Express Card locked at Gen2 by BIOS ( No supervisor password, sadly) as I understood. Another possibility would be abandoning Windows as Dota2 kind of works on Linux but I'd like to avoid that as it's not so stable and I play competitively so I need stability more than anything. I would buy the 1.3 Setup but I don't know if it could do me any good, I'm a student on a tight budget so I'd rather make sure that I'm not wasting my money before buying the adapter and the software.

I'm having quite a few problems DSDT overriding on my T430. At first I tried with the toolchain suggested in the guide, using the intel decompiler to dump and disassemble the DSDT table and then modify it as told, recompiling it with the intel and overloading with the asl.exe from Windows Driver Kit 8.1. That obviously did not work. I tried to search for people who managed to do this on a T430 with very little success. DSDT Override on Thinkpad X230 — BRIGHTBULB I found this guy who managed to do the same on his X230, I downloaded his DSDT and decompiled it with iasl (intel one), compared it to mine and the PCI0 part was pretty much identical except for his QWordMemory. I even got his same exact compile error unrelated to the PCI0 device which I had fixed the same way he did. I tried messing around with it a bit more and gave up. Today I tried with a different toolchain, I used the Windows ACPI 5.0 compliant asl.exe (The same one from before, from Windows Driver Kit 8.1) to dump, decompile and recompile my DSDT table with the 32bit patch applied to it (Windows use a whole different syntax, I figured it out and even compared it to the windows decompiled version from brighbulb and it's consistent). Overloaded that and still nada, boot BSODs at the exact same time in the loading screen it did earlier. I can post my asl or aml files for both windows or intel compilers if anybody wants to take a look at them, I really don't know where to go from here.

I have just checked and the BIOS settings are exactly as you said, EC enabled on AUTO. I have also checked my TOLUD and it's sadly 3.5GB with 8GB installed ram, I have only the HD4000 Ivy iGP and from what I have read the only solution would be a DSDT override. I think that the best way to go at it would be first trying if DSDT works with my locked down BIOS and then purchasing the required connectors, hoping that it works. (About this one, do you have any specific set-up to recommend based on my system specs?) In the end I would love to go for the most stable/compatible set-up possible, as I said all I need is a stable 70-80 FPS on Dota2, all settings low except for the resolution which has to be 1920x1080.

Hello everyone, I have bought an used T430 a few months back and I have been loving it. The only thing that is wrong with it is that it came with a preset supervisor password but it hasn't really been a problem yet (except for the fn and ctrl swap, goddamn Lenovo why.) I have been able to wipe my HD completely, throw grub on it and so on. Lately I have been thinking that I'd like to play Dota2 with it on my other apartment, plugged to a 1920x1080 monitor and even with all settings at low ( I don't really care for anything else ) it doesn't cut it for my standards. I have a plethora of video cards laying around gathering dust that I won at tournament some time ago, a 4850, 5870, 6990, 7850, all ATI. I have been thinking about an e-GPU setup, the only goal is having Dota2 running at a stable 60 FPS while at 1920x1080, all settings low. Do you think it is possible without being able to change any BIOS settings?
