Using internal nVidia & egpu with nvidia card

Hi all

Ive been tearing my hair out the last few days.

I have a Clevo based laptop with internal intel and 2080Smq. My egpu housing is a razer core v2 with a 2080ti. The egpu has a monitor hanging off the primary DisplayPort. I am also leaving the lid open and the laptop display on.

monitors are setup in extended mode.

in short I can install both the notebook nvidia drivers and desktop drivers in any order to make device manager show both cards working. Everything is great but when restarting generally the egpu card shows as an error yellow triangle (code 18 reinstall drivers)  and is not accessible in nvidia control panel  or other applications. If not the egpu then the internal card stops functioning.

this is irrespective of the same or common driver versions or order of install. 

Have I hit a limitation or am I missing something?

To get things working I simply install the same drivers again. 

thanks In advance for any ideas or tips.

@foobaru, This is fairly common when the dGPU and eGPU are the same brand. I'd recommend running DDU to remove all Nvidia graphics drivers and open [OPTIONS] in DDU to check a box that prevents Windows from auto search and install drivers for devices. Once these tasks are done, you can install a common set of drivers with both dGPU and eGPU active.

great this worked well! second issue im having now is when i load a game, e.g. GTFO and start to play my entire eGPU housing switches off and requires me to pull power to reset the PSU to reconnect back to the PC.

i am forced to restart as windows hangs (but music stilll plays).  It seems to happen consistently, Division 2 the same thing occurs, load the game, and when the gameplay actually starts pop! egpu dead....

any thoughts on why that could be? ive tried different TB3 cables, different games all to no avail..

@foobaru, are you overclocking or increasing the power limit on your eGPU? I had something similar occur when I was trying to overclock the 2080ti on an Asus XG Station. It only has a 300watt external power brick so anytime the GPU tried to draw above this, it tripped the breaker and I would lose video but keep hearing sound.

@ishikawa_goemon, good point. I’m not over clocking the card but have peripherals galore handing off the unit. 

so would it be fair to say that if power is tripped that it’s likely drawing too much? I hadn’t considered that.

i tried 3 machines and 2/3 trip it ... which is also odd. 

I will start to isolate devices tonight

@foobaru, if the behavior you see is a sudden cut-off of power after things have been operating normally, it is usually an indicator that some sort of power protection system tripped.

Another thing I noticed was that on the XG Station, after the power tripped, I had to disconnect the AC adapter and then plug it back in (maybe reset some sort of breaker?) before the system would work again.

Did you have any luck after removing the peripherals? If that is something you absolutely must have, you could consider getting a powered USB hub. This would decrease the draw from the Core V2s power supply.

@ishikawa_goemon, thanks again for your suggestions.  Ive done exactly that.  Ive got powered hub now to help out.

 

things are neeeaaarrrly working 100%.  ive got a bizarre issue in certain games.  Division 2 and GTFO it occurs, COD:MW2 it goes ok.  The issue is about every 5 seconds it stutters for a second.. frames drop right down and then shoot back up....

this seems to be only on the external GPU (ti).

Any thoughts as to what this could be? i *think* its consistent if i boot and disable the internal Maxq card, and only use Egpu that things go smoothly.....

I can categorically confirm that having both the internal and external nvidia cards active causes the external to stutter every 2-3 seconds.  once ive disabled the internal nvidia gpu things are smooth as.  I can do this mid game.....

@foobaru, your observation is something that I can confirm as well. On a laptop, when I have the internal dGPU and eGPU active at the same time, there is stuttering. I think this may be tied to Nvidia's Optimus software.

As for the games you mentioned, have you tried running Division 2 on DX11? When I was playing Division 2 with an eGPU, anytime I tried DX12, the stutter was insane. Not sure about GTFO but sometimes it can be tied to the game itself.

Has the power tripping behavior improved?

firstly let me thank you for keeping an eye on this thread and continually providing helpful tips.

the random resetting of the eGPU housing has diminished but it does happen every now and again.  to that end i have a measuring meter for power from wall sockets. i used this.. the absolutely peak load i could generate was 291w which is far below rating.  not shortly after that it turned off and the last reading was 261.9w..... so still stumped.

 

Things got really bad with the stuttering, it was happening at windows desktop. tried all sorts of combinations of disabling the iGPU dGPU while running the eGPU and still couldnt get it to run acceptable. to that end i have to reboot with with the dGPU disabled prior to the reboot to have an acceptable experience with the eGPU.  i tried the different renderers where i could change them... again no appreciable difference still stuttering!

 

so im completely stumped. ive tried the last 4 drivers from nvidia... so not the most recent...:(
