I tried to do that way + setting Gen2 link speed and it works...until I run GPU-Z or any other application - system freezes and i get BSoD :/ It seems that when I run my GTX660 with 1.1Opt, all is working great. But when trying to do anything to force GTX660 to 1.2Opt system freezes after run any application - question is why?

OK. Here's my step-by-step DSDT override - trying to do while eGPU disconnected: 1. Command iasl.exe -g 2. The File that has been created: dsdt_CBX3.zip 3. I found in that file line: Device (PCI0) { Name (_HID, EisaId ("PNP0A08")) Name (_CID, EisaId ("PNP0A03")) Under the last DWordMemory entry in that area (line 2272) I have 'QWordMemory' and I've added additional 'QWordMemory' that was provided by instruction (shown on my screenshot as red buckle) and this how it looks like now: 4. I've made an .aml file without any error by command iasl dsdt_CBX3.dsl (download an .aml file here: DSDT.zip ) 5. Loaded table into registry as shown below: What I have to do now?

Thank You for Your answer. 1) I tried the method with connecting eGPU before booting, but sadly it doesn't work - the computer won't wake up, no backlit of the screen (jumper SW2 set to 2-3, SW1 to 1). I also tried to set the SW2 to 1-2 and SW1 to 3 and then to run the DELL - and OS starts, but doesn't changed the value DFA to CFA in Device Manager, what means eGPU probably isn't detected at boot 2) I've done DSDT override earlier, there was error when iasl tried to generate .aml file so I used a newer version of iasl that ignored this error and generated .aml file - I loaded this file and after restart in Device Manager I see something like a "big memory." - please see screenshot: Should I do DSDT override again with older iasl and without any errors or is there other solution maybe? EDIT: Added screenshot with error when trying to do: iasl dsdt_CBX3_EGPU.dsl

Hi nando, Using Your latest Setup 1.30 test2, my GTX660 is successfully found and switched to Gen2, but I'm getting "no solution found" when I run compact. DELL E6430, Win 7 32-bit. I deleted the incorrect "PCI bus" section in devcon.txt file. Please see attachment and help please...

Hi feodor_ I have Dell E6430 (+GTX660) and I have exactly the same problem. I've had error 12 and I made DSDT override too. Now, my Device Manager looks exactly the same like Yours and only 1.1Opt is available. I know the solution to get 1.2Opt working is probably to change the value of PCI bus (first of Your screenshots) from 00000000DFA00000 to 00000000CFA00000 (more info) - but when I'm trying to run Dell with eGPU attached there's only blank screen without backlit. Also, solution could be forcing PCI bus to 2.0 mode (called also as Gen2; G2) by setpci -s command, but i don't know how to do that (call iport g2 command doesn't make it). I tried something like setpci -s 0:1c:2 CAP_EXP+40.b=42 (0:1c:2 is graphic card info, 40 is starting address of Express Card and that address +2 should make it running in PCIE 2.0 mode - but doesn't work too).

Hi nando! Thank You for Your amazing work for us. Could I ask You to help me - how to set G2 link speed by setpci -s command? The command "call iport g2 2" is not working My laptop is Dell E6430 and graphic card is 10de:11c0 (0:1c.2). When I'm using code above, all is working but only with 1.1Opt.
