Setting eGPU as primary GPU (GTX 1050, ExpressCard)

System Specs:

Dell Latitude E6430: i7 3740QM, 8GB Ram, Nvidia NVS 5200M dGPU, Win 10 64bit, ExpressCard interface.

EXP GDC Beast 8.0, with an EVGA 1050 SC, connected through the ExpressCard interface, powered by a 96W 12V DC power supply. Using the Nvidia 375.63 drivers (Which seem to be the only 1050/TI driver that doesn't give a Code 43 Error, thanks to jimteo for sharing that).

 

 

The 375.63 drivers installed without any trouble, didn't need to modify anything. Device Manager detects the 1050 without any errors, as well as HWInfo, GPU-Z, and the Nvidia Control Panel. However, I can't seem to be able to set the 1050 as the main GPU to be used. I've tried setting it as the Physx Processor in the Nvidia Control Panel, as well as setting it to be used for CUDA, but games and 3DMark11 still uses the dGPU (NVS 5200M). I've tried disabling the NVS 5200M in Device Manager, but everything starts using the Intel HD iGPU instead. Can someone please explain to me how to set things to use the 1050?

I'm sorry if this is a stupid question, this is the first time I'm trying an eGPU setup.

Thanks

Removing all existing NVidia drivers, using 'DDU' to disable automatic driver installation, loading the eGPU desktop drivers and disabling the dGPU with Setup 1.3x has worked for me to fix this issue.

Hi,

 

I´m thinking about building a pretty similar eGPU-setup. Key facts:

- DELL E6420 with Intel i7-2720QM (iGPU) and NVS 4200 M (dGPU)

- PE4C v3.0 adapter --> using ExpressCard, giving PCIe x1

- eGPU: GTX 1050 Ti, still searching for "my" manufacturer (ZOTAC unfortunately too noisy)

- PSU: DELL DA-2 for powering the PE4C adapter (will likely choose GTX 1050 Ti without requiring additional power of an ATX, so power will be <= 75 W which matches capabilities of PCIe)

I´ve read a lot the last days and also checked TOLUD value, which is quite below 3.0 GByte - so I was pretty happy to not needing to use Setup 1.30 which seems to me like a quite deep (and perhaps risky) dive into the system.

 

My plan was/is:

Notebook docked using eGPU: Plug in EC, power up eGPU, have fun playing.

Notebook undocked (e. g. on train/plane etc.): Using iGPU and dGPU.

 

My questions (pretty sure all of them to king of eGPU @nando4 :)):

1) Is this plan realistic? Or did I miss something?

2) Is the disabling of dGPU with Setup 1.3x a permanent step or can I "quickly" switch between dGPU- and eGPU-setup, e. g. with automated scripts or something like that?

3) Can therefore the NVS 4200 M (currently using driver 376.33) and GTX 1050 Ti use the same driver? In other and simpler words: Can I still use the dGPU (pretty related to question #2)?

 

@ybodhanya: Did you finally manage to use the GTX 1050 on your system?

The disabling/enabling the dGPU via Setup 1.31 is an easy step. The biggest problem here is a unified driver that supports the NVS4200M and the GTX1050Ti. As it doesn't exist you'd have to create your own. Those GPUs are different product lines.

With my ZBook 15 G2 (K2100M) + GTX970 + Win10, I resorted to deleting the K2100M driver and installing the Geforce GTX970 driver. Otherwise the eGPU would get detected and have no errors against it but would error "no display detected", so was not usable.

May be a matter or battling through the challenges as they present themselves?

Thanks for your (very quick) reply! So:

1) How do I create my own driver? 🙂 That´s a complete new dimension of my eGPU project.

2) Maybe better (or easier and less time-consuming) to let dGPU disabled and only use iGPU when traveling? That would be a compromise... 🙁

Or switch between the NVS4200M and GTX1050Ti drivers by unloading/loading the one you require. If you find a better way then pls share.

@e-raser Not yet unfortunately, I don't have enough free time at the moment for much gaming, and I'm kinda broke so I can't get Setup 1.30/1.31 right now. Will hopefully be able to get it by the end of the month.

@nando4 Actually, if I remember correctly my NVS 5200M ran fine using the GTX 1050 drivers that I installed while testing the 1050. I can test it out again later if you want.

Okay, if that could be automated I would be fine - still a compromise but also still acceptable.
 
So new questions:
1) Is there a way of "scripting" (Nvidia) driver switch on the fly @ Windows?
2) The root source seems to be the dGPU (NVS 4200 M). I´m not fixed to GTX 1050 Ti, but I quess it doesn´t matter what eGPU I´d choose - it would always end up in the same problem (as you mentioned: different product lines = different drivers), right?

That sounds good! So if you "just/simply" would use Setup 1.31 to disable your dGPU (NVS 5200 M), you should be done, right (@nando4)?!?

@e-raser Hi, I just tested my NVS 5200M with the 1050's GeForce Drivers (375.63) again, to make sure I didn't imagine it last time. It ran fine with those drivers, tested it with Assassin's Creed Revelations. That means you shouldn't need to reinstall drivers every time you want to use the dGPU, or vice versa. Should probably wait for Nando's confirmation on this though.
