    My External GPU Challenge

    • I really have a tough conundrum today;
      I’m trying to connect an external GPU to my laptop…
      What I have:

      • Computer - Sony Vaio e series laptop (EA37FH), with a dedicated internal GPU ATI mobility HD 5670
      • External card unit – SAWAKE EXP GDC Beast Laptop External Independent Video Card Dock
      • Discrete GPU card – Powercolor HD 7990
      • Extra PSU – Thermaltake Tough power 650W



      What I’m trying to do:

      1. physically connect the e-gpu to my system via the express card port. The card is lighting up, the psu is working just fine (go)
      2. making my OS (windows 7 x64) recognize the new card in “device manager” (go)
      3. play games and running 3d mark benchmarks with the use of the e-gpu (no go)

      My problems and symptoms:

      1. I am unable to install the driver set of my external gpu on this laptop: It just “runs” a super-fast iteration of the installation without doing any real installations of the software. Also, Its’s not even synching between the software and the new hardware. (no go)
      2. I tried to uninstall the mobility dedicated internal gpu with DDU and completely disabling and uninstalling it from the device manager. I also made sure windows will not automatically install the drivers for the mobility gpu (no go)
      3. So basically. There “is no way” to install the dedicated new drivers for the hd7990, even if I completely disable the inboard gpu (no go)
      4. I heard of a way of doing it with a special bios hack with a 25$ software that I just didn’t seem to be able to find – and trust me that I am quite good at searching. (no go)

      My question:

      1. Can any of you tech-savvy engineers/super-geeks/crazy technicians help me figure this out?
      2. If and how can I disable the internal GPU with a magic bios hack or anything else?
      3. Can you please help me with tutorials, experience-based advices, useful links to software and manuals?
      4. If any of you people did it before, and struggled like I am – please dig me out of this pit hole of a mess I am in right now.

    Just watched this video are you connecting to an external monitor or expecting to use your laptop screen? also have you connected all the 6/8 pin power leads?
