@Angelo, suggest you upgrade to win10. They you'll be able to disable the Nvidia dGPU graphics due to either being too old or Quadro type, and install the Geforce driver for your eGPU. That mechanism is unavailable in Win7 since secondary video adapters don't work if the primary dGPU is disabled.

I got a new Exp Gdc Beast and my laptop booted up, but now when i boot up the graphics card don't spin, and im sure i have plug in my psu correctly to the Exp Gdc and the graphics card, and when i look into device manager the egpu is not there, i tried booting with my wifi card in, put it to sleep and swap to the mpcie adapter, but it still no detection after i clicked search for hardware changes. my graphics card is a Gigabyte Gtx 750ti 4gb.

Hi again, I managed to upgrade. Now when going through the same steps, the laptop freezes when trying to get to my desktop. I feel like I'm in the right direction just need the additional fixes.

I recently bought a used ExpressCard EXP GDC Beast (not sure which revision) to try and use with my HP Probook 6460b. Sure enough, I got an error 12 in device manager after I installed the NVidia drivers for my GTX 1050 Ti. Did a bit of reading, and then removed the 16GB of RAM and replaced it with 2GB. This time I got an error code 43 in device manager.

So it seems likely that I need to apply a DSDT edit. I'm totally clueless when it comes to DSDT editing despite knowing a fair bit about PC hardware. Looking on the forums I've seen DSDTs for other Probooks, but not my exact model. There are two that are very close to my model (Elitebook 8460p and Probook 6560b) but I'm not sure if they're similar enough to my 6460b to try the DSDT.

It also seems like there are a few other (safer?) ways to approach an Error 12, like eGPU Setup 1.35 and some BCD edits. Should I try these before attempting to apply a DSDT edit?

Hello, i recently bought EXP GDC 8.4 Expresscard version, it works fine without any game opened. But, when i try to run any game, the GPU shuts off and the notebook get back to the IGPU. I have to remove and reconnect the expresscard to get it working again. Can anyone help me? (I set the delay of PTD to 7 seconds on the egpu because the notebook don't start when it is off.)

My PC settings: 

HP Probook 6470b

GTX 760 ACX EVGA 2gb GDDR5

PSU: Gigabyte PB500

This might be due to the PCIe link going to Gen2 as the card begins to see utilization and then the link fails due to the unreliable signaling on the GDC Beast cabling with a Gen2 link. All your power cabling is right on top of the signal cable, which creates a lot of interference. Move all power cables to behind the card, and the PSU away from the beast itself. Spread them out as much as you can like this, along your table:

PSU <--> Power Cables  <--> eGPU <--> Signal Cable <--> Laptop.

If that does not help, drop the PCIe link speed on the Expresscard port to Gen1. You may have a BIOS option to do this, or it might need to be done via a different method, such as nando's Setup1.35 software.

Alternatively, it might be a power issue, even though the PSU itself is solid in theory, it might be malfunctioning. Can you test it separately (or just use another PSU instead for the eGPU for testing)?

  • i only have the nando 1.3x setup, i tried to downgrade gen2 to gen1 and still the same. Yesterday i made it work on The Witcher 3, but the GPU usage ingame was 15% and i got 5 fps even on low settings. After it, i rebooted my notebook and i couldn't open any game anymore. I bought the PSU 1 week ago, it's new.. and i tested the GPU In another pc and it works fine.. when i run a game, the SPU and GPU do some noise and suddenly shuts off..

The PSU might be new, but it just might be faulty. Since everything else seems to work and it is not a Gen1 issue, I'd be looking at that next.

Hi there!

Recently i've bought an GTX 570 and connected it via Expresscard-Slott to my iGPU-only HP Elitebook 8460p. I saw in the Bios settings, that i have the option to choose between Gen1 und Gen 2. So i tried to use the Gen 2 Version (Gen 1 was the default one) to see if there is going to be any improvement, but instead i got more of performance drop. I couldn't find any information if the Laptop supports the second Generation or not, but i wanted to ask, if any of you has experienced that kind of a Problem?
