I have the following eGpu configuration:
HP Probook 6570b with Intel HM76 Chipset and Intel HD4000 VGA
EVGA Geforce GTX460 FPB
PE4C V3.0 adapter
Corsair CX500M power supply
I get error code 12, even if I put only 4GB ram into the machine. This is laptop is running Windows 10, and I was told under Windows 10 this 32bit addressing memory problem should not cause a problem at all.
That why it is so odd. Moreover, I have a HP 620 laptop as well, that is a much less advanced machine, when I connect the eGpu to that, it works. I had to set jumpers to SW1-2 SW2-2 positions, this way, when I load Windows 7 32 bit on that laptop, put it to sleep, after waking up Windows switches to the Geforce GPU and image appears on the outer LCD, but an image also remains on the built in laptop LCD as well, and I can move the cursor from the outer LCD to the built in LCD, but on the built in image you can only see the desktop background, no menus or icons. If I don't put the laptop to sleep, Windows reports error 43.
When the jumpers are in 1-1 positions, so when the delays are switched off, there is blank screen on the HP Probook, the outer LCD reports no signal, on the HP620 the HP startup screen appears on the laptop LCD, but the boot process doesn't continue, and no signal on the outer LCD either.
I set the jumers just randomly, don't even know what their real purpose is, because I couldn't find any description about it. Is it possible I should adjust them to get the error code 12 to disappear. It seems odd that even with 2GB of ram there is error code 12 on the Probook, I wonder if that error report is real or it is false and limited addressing memory space is not the real problem.
Any advice to get this working on the Probook?
