Use laptop GPU to game while using EGPU for mining
Windows automatically disables the internal 1050ti when the eGPU is plugged in. But I would like to use it for gaming still if possible in order to avoid slowing my mining, or causing crashes in game. Is there any way to re-enable the card? In device manager the option to re-enable is greyed out.
XPS 15 9570, Razer Core X w/ 3060ti
I too have the same issue, I got a 2080 maxq built in and a 3080 egpu, just noticed it is only using egpu. I can't even open nvidia control panel as no display is plugged into nvidia device (egpu is back feeding video to laptop screen)
Let me know if you found a work around.
the reason that your Dgpu is disabled is beacuse that different driver versions installed at Dgpu and Egpu. So first try this workaround:
iii) error 43: running a NVidia dGPU and eGPU
If you have NVidia dGPU as well as NVidia eGPU then it's likely because of having the mobile NVidia and desktop NVidia drivers loaded simultaneously. Proceed to disable your dGPU, uninstall ALL your NVidia drivers , use " DDU " to disable automatic driver installation and clean NVidia registry entries. Then do a 'clean' install of the latest NVidia desktop driver.
then your Dgpu and Egpu should be enable, you could try to use them in meanwhile.
I'm also very interested with this, as i want to create a set-up of gaming laptop + egpu. (i have my reasons not to opt for desktop)
In case im not using any of the laptop or egpu, i also want to mine on both Cards (laptop + egpu).
@joshuaind, Like @klabc stated, the mismatch in drivers is the reason only eGPU was working. Run DDU to remove all Nvidia drivers then download the latest desktop version drivers. Install the drivers when both dGPU and eGPU are active and present in Device Manager.
@itsage Thanks for the reply. Aside from making both cards work i also want to find out the performance impact if both used for mining or if any one is used for mining and other is gaming. I understand that there will be significant impact on gaming as both are taking pcie lanes, what about in mining? can anyone share their thoughts. Thanks!
@joshuaind, For mining thermal management is most crucial. Bandwidth doesn't make a big difference. Most mining software give you the option to specify the card/s used for mining tasks. You can disable the one you intent on using during gaming then switch it back to to enable for mining once done gaming.
