Is this still relevant about error code 43?

Some of the instructions are so old it's tough to know whether the more recent drivers have come to fix these issues.

Had no luck. The parts are fine, it's something in my config.

Following this thread the settings don't seem to stick. Process is:

1. Reboot into DIY eGPU 1.3 Setup

2. Set settings

3. Reboot

4. Boot into windows

5. Install graphics drivers

6. Reboot and use setup.bat from DIY eGPU 1.3 menu.

7. It then shows menu "Windows 10" or "DIY eGPU 1.3" and selected Windows 10.

Parameters are holding: dGPU is definitely disabled.

Could it be an issue that I'm installing the GTX960 drivers when my computer has Optimus? Are there different drivers I should be installing?

Ensure you are using Setup 1.30 to downgrade the link rather than any BIOS settings or any earlier versions of that software. Check it's downgraded within Windows using GPU-Z while placing the eGPU under load. It should report x1 1.1 rather than x1 2.0.

I think I need to do some playing around with it. I do see x1 1.1 but all of the stats are either unknown or 0 MHz. I'll post back after I've tried a few things.

I downgraded the link successfully but same issue is occurring. I disconnected all of the peripherals just in case.

I'm not sure how to test the components individually. They're all new and the setup reflects the instructions I linked to. Power switch is working both on PSU and on the board. SW1=1 SW2=2-3.

Couple other things I noticed:

- Have to disconnect the PCIe card before booting up--otherwise it stops at the initial "Thinkpad" load up.

I have this as my startup:

call iport dGPU off

call vidwait 60 10de:1401

call vidinit -d 10de:1401

call pci

:end

call chainload mbr

I have checked that 10de:1401 is the correct device id but I'm unsure of the other lines. The instructions said to use this:

call speedup lbcache

call iport dGPU off

call vidwait 60 10de:1004 (your Hardware IDs may differ)

call vidinit -d 10de:1004 (your Hardware IDs may differ)

call

call pci

call grub4dos mbr

but I understand the first line isn't necessary and I wasn't 100% sure that the last line wasn't out of date (I had tried it once before while on Gen2 and it didn't work).

Is there any more information I can provide that would help dig further into the issue?

I followed the instructions here although I understand they're 2 years old. All of the steps made sense and were easy to complete. I do have the DIY eGPU setup 1.3.

I'm in Windows 10 now with the drivers installed. It recognizes the GTX960 but says Windows has stopped this device because it reported an error. In events it says:

> Device PCI\VEN_10DE&DEV_1401&SUBSYS_32011462&REV_A1\4&16c2da34&0&00E2 requires further installation.

Driver version is 10.18.13.5900.

I'm unable to start Nvidia Control Panel. Any ideas?
