Thank you, douirc, for pointing me in the right direction. I have been able to install the E6400.aml file as a DSDT override on my Dell E6400. I can now run the eGPU with 8GB of ram installed. Here are some quick summary points that may be helpful to others. 1. The ASL compiler for Windows 10 will be installed in C\Program Files (x86)\Windows Kits\10\Tools\x64\ACPIVerify (just as you mentioned). 2. The aml file (e.g. E6400.aml) needs to be installed in this directory 3. After loading the revised aml file, testsigning needs to be turned on. 4. I also needed to install Visual Studio 2015 to prevent a missing dll error in running the Unigine Heaven and Valley benchmarks. 5. I am not able to boot with the Expresscard installed, but simply put the laptop to sleep and then insert the Expresscard.

System: Dell E6400 w/Intel 4500MHD, Windows 10, EXP beast V8 Expresscard, GTX 970 The above system works well with only 2GB installed. I am attempting to do a DSDT override using an E6400.aml file provided by user dummyaccount ( who successfully performed a DSDT override for his E6400/4500MHD laptop). After running iasl.exe, then attempting to use the command asl /loadtable E6400.aml, I receive an error that "asl is not recognized as an internal or external command". Any help in pointing me in the right direction would be very much appreciated.

With regard to my Dell E6400 and error code 12, I have found that the E6400 DSDT file does not contain a DWordMemory entry. However, User dummyaccount posted E6400.aml and E6400.dsl files for his Dell E6400 that resolved the Error 12 issue. I believe that I only need the E6400.aml file. What steps should I take next to override my existing DSDT file by using these files?

Thank you for your advice. I replaced the Dell DA2 with an ATX power supply and used the connecting cable provided with the EXP Beast (V8). If I leave the Express Card in during boot, I get a pixelated screen in which I cannot fully recognize the screen details. This is also true when the DA2 is used to power the system. Thus I can't see the Setup 1.3 boot option choice and the system boots into Windows. If I leave the Express Card out - select Setup 1.3 - insert the Express Card - then turn on the switch for the ATX supply - Success! For the first time, I am able to get the EGPU to be recognized. If I am late turning on the switch, I use the F5 to scan and the EGPU is immediately recognized. Based on your Dell E4300 experience, what specific steps should I apply in Setup 1.3? Does it make a difference if I have 2GB installed for testing? Finally, I do remember seeing TOLUD =3.5GB in Setup 1.3 when I had 8GB installed. There are three MPCIE slots in the E6400, one of which is dedicated to Bluetooth. If I turn off Bluetooth in the Bios, will that have any positive impact on the size of TOLUD?

I have the following setup: Dell E6400, 4500MHD, 8GB Ram, Windows 10, Setup 1.3, EXP Beast V8 Expresscard, Dell DA2, Nvidea 750ti. I am able to run the 750ti on an external monitor by using only 2GB of ram. When booting into Setup 1.3 (as a disk image), it is not able to recognize the EGPU. All combinations of unplugging the power supply, then plugging in the express card. and so on - do not seem to work. When booting straight into Windows 10 with 8GB of ram, I receive Error 12. What are my next steps as far as troubleshooting? Will I need to perform a DSDT override as well as use Setup 1.3 to make this work with 4GB+ ram? Or can Setup 1.3 by itself resolve the problem?
