As it was late and I was bored, I disabled the video card from “Device Manager”, turned off the computer and went to bed. I solved the problem on my 740M (so it seems), I uninstalled the drivers 355.60 and I tried to install the drivers mentioned in the other thread (the 341.61) with a clean install, but the problem has not been resolved.

Then I have to do roll back the driver to 305.46, reboot, and then reinstall 341.92 via the Device Manager method to get it going again. Problem is that the next time I reboot the card will code 43.

My process went something like:ĭisconnect hard network connection and set WI-FI to metered. I’m not an expert, not sure how much of this is necessary or what I was just doing because I read it on forums. This is all documented elsewhere so I’ll paraphrase. It’s a Sager P170EM notebook with a Quadro K3000M and Intel HD 4000. The windows option to prevent this did nothing. Once I figured out how to get things working initially the problem became Windows Update constantly overwriting the driver I deliberately installed. I’m pretty close to having this fixed for me anyway… Need the last 10% though. But nevertheless the advice to use R340 will allow both devices to work. In your case, I suspect the K600 is being enumerated as primary. The behavior will vary depending on which GPU is enumerated as primary by the system. Note that there are more details to this that I haven’t covered. In the future (probably later this year) I expect NVIDIA will release drivers that allow the usage of Fermi devices in WDDM 2.0 mode.įor example, this R340 driver is compatible with both Q600 and QK600, and should allow you to use both devices in Win10: This is a WDDM 1.3 driver and will work correctly in win 10 both for Kepler and Fermi devices. To use both Fermi and Kepler devices in the same Win 10 system CURRENTLY it is recommended that you use a driver from the R340 branch. The latest drivers currently are from the R352 branch. Your Quadro K600 is a Kepler device and currently has WDDM 2.0 (i.e. Your Quadro 600 is a Fermi device, and currently only has WDDM 1.3 support via NVIDIA drivers (this will change in the future).

in systems with certain mixed GPU configurations.)

I’m not an expert on this as windows 10 is pretty new, but the new WDDM model in windows 10 imposes some nuances on behavior of NVIDIA GPU devices from architecturally different generations (i.e.
