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
[ALL OF MY GEAR IS BEING DETAILED WITH SPECS AND PICTURES RESPECTIVELY]
What I’m trying to do:
- 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)
- making my OS (windows 7 x64) recognize the new card in “device manager” (go)
- play games and running 3d mark benchmarks with the use of the e-gpu (no go)
My problems and symptoms:
- 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)
- 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)
- 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)
- 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:
- Can any of you tech-savvy engineers/super-geeks/crazy technicians help me figure this out?
- If and how can I disable the internal GPU with a magic bios hack or anything else?
- Can you please help me with tutorials, experience-based advices, useful links to software and manuals?
- 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?
yes I did, but the problem seems to be installing the new graphics drivers correctly. that is a big big issue still
