Pascal GPUs with Dell Precision M6600

[Nowan]

Big discovery of experimenting. Got the chance to try my quadro p4000 from my m6700 to my m6600 cause I was inspecting my p4000 to insure that my thermal pad and paste is making contact while vram Half covered. it booted from bios to os with no issues and the best part is nvidia Optimus doesn’t switch off from powering down like the P106M does. As of now I couldn’t the gpu because it’s missing the option to use the nvidia processor instead of the intel gpu in the nvidia control cause of something to do with editing the hardware I’d and and drivers not sign now after editing. like the third try I did with P106M but with more updated driver with same issues. Not sure I need to edit something else then hardware I’d to enable the option to switch. I’ll continue testing tomorrow and find ways get gpu working to do some benchmarks.

You can sign the drivers yourself after doing modifications.

Update...  I was unable to get the option to use Nvidia gpu instead intel gpu on newer driver. has optimus been discontinued on newer drivers? same on older drivers the Nvidia  control panel does not start after installation instead run it manually by going to the folder. it has the option and select it to the gpu but no change after apply still use the intel gpu. i try using windows 7 to see any different on the gpu switch option control panel is there but still wont use the Nvidia gpu, after installation of Nvidia the aero is disable u cant reenable it. even tho the drivers are signed. 😓 i did one final test is disabling optimus bios and enable windows 10 startup sound to see if it boot with no issues without optimus and it successfully boot to windows 10 as it played startup sound. dell never create edp cable for 50pin edp screen (well for interposter for 10bit ips lvds screen ).

Just wanted to post an Update, since I am in the same situation. On the M6600 the card will change form 10DE 1BB8 15CD 1028 to 10DE 1BB7 14A1 1028 for some reason, after modifying the driver nvdmig.inf the driver will install. you will be able to see both cards installed. However they have their own discrete outputs, the intel card will have the internal and external monitors and a "Phantom monitor will be on the P4000". The only workaround I found is to disable the Intel video card on device manager and you will able to use the external monitor (HDMI in my case) with P4000 for games. if you want to use it on the internal display you will have to use mirror displays instead on Extended. I am still playing with Nvidia settings on the control pannel to see if I can modify the display settings for the Phantom Display.

 

Just in case anybody is in the same situation on 2024
