My eGPU issue was a driver problem. Works fine with 375.70 driver, not with newer ones. Seems to be a common problem with new Nvidia drivers.

It would be a good idea to include your system setup in your signature.

 

On our laptop TOLUD is set automatically if it detects an eGPU prior to boot. You could try and set it manually lower using UEFI variables to check if the problem persists.

Thanks, added the specs to my signature.

DIY eGPU Setup V1.3 shows TOLUD 2.74 GB so it should not be a problem. it also shows that both dGPU and eGPU have been assigned memory areas. I tried playing with different options, currently my startup bat does set Gen 1 link for eGPU, does eGPU compaction with dGPU ignored and then disables eGPU. With this eGPU takes pretty much the same memory areas normally used by dGPU.

if I try to initialize the eGPU in Setup V1.3 then addresses get somehow messed up.

Still no picture to external monitor and always Code 43 in Windows. I tried lspci -vvvv in Windows and it shows the following. For some reason it shows the memory areas as disabled. Could be because of code 43 or maybe is the problem itself?

Unfortunately I don't have any other power supply or GPU card to try.

Disable fast boot in BIOS. Try to boot with the eGPU connected and powered prior to boot.

 

Hi,

Fast boot was already set to slowest setting. I have tried connecting eGPU at all possible stages always having the same issue with code 43. I have tried sleep + wake and all the usual tricks without any help.

I noticed that Device Manager does not show any memory areas for the eGPU in e6430. I tried the setup on Dell e6220 and immediately got picture (internal screen went blank, external monitor connected to eGPU working already at BIOS level). However when I tried to install Nvidia drivers in Windows 7, I got the code 43 on that computer too and eGPU is working as generic VGA device.

I'm trying to get eGPU working with my e6430. So far I always end up with code 43 in the Device Manager and no output to the display connected to eGPU HDMI port.

- e6430 with 5200M dGPU, 8 GB RAM, SDD, HDD

- Bios A18

- EXP GDC V8.4d ExpressCard version + Dell DA-2 PSU

- GTX1050 Ti 4 MB

- Windows 10 64-bit

- Nvidia drivers 376.19

Windows sees the eGPU and drivers install without errors. So far I have tried: removing all Nvidia drivers with DDU and re-installing the driver. Disabling dGPU with eGPU Setup 1.3. PCIe compacting with eGPU Setup 1.3, always hangs when asked to press ENTER to return to the menu.

Any suggestions how to get the card working?
