Got a GTX 1650 and GTX 590 in a system. Long story. (no igpu)

PC only boots when the 590 is installed and used as vid output with the 1650 alongside. I know why but that's a separate issue.

In device manager the 1650 is not currently recognized. If I install drivers for the 1650, will it interfere/remove or mess up my drivers for the 590?

The 590 is currently my only way of using the PC so if I somehow disrupt those drivers and prevent 590 functionality, I am in big trouble.

Thanks for your input
 
The last drivers that supported the 590 were released before the 1650 existed which is where your problem lies. You cannot run two different nvidia driver versions on the same system and I'm not aware of any workarounds.

It's unfortunate that they didn't just opt for video outputs on the board since all SNB era client CPUs have IGPs.

The only way is to use a driver that supports both. Unfortunately the last ever Fermi driver (391.35 for 64-bit Windows 10) only supports up to Pascal such as GTX1060, and Turing is a generation too far.

The alternative is to use a cheap AMD card instead, since unlike with Windows 7, Windows 10 works fine with completely unrelated drivers from different manufacturers both installed. The problem with two nVidia card drivers is parts of the them would be written to the same system locations.

Hi,

I have a GTX 1650 and GTX 590 installed in a Dell Alienware R3 mobo with an i7-2600 CPU and 4GB DDR3 RAM in dual channel configuration.

In order to be able to post & boot when the 1650 is installed, the 590 must be installed and plugged in as primary display to the monitor at time of pressing power button.

Otherwise, it freezes and fails to post, no display, OS corruption ect. Caused by (updated) crappy Dell BIOS refusing to work with Turing.

However, drivers for 1650 are installed and 590 is running on Microsoft basic drivers so after boot OS has lower resolution and looks crap.

When I take the signal cable out of the 590 and plug it into the 1650, image is proper and full resolution and works, but can’t use OS because trying to click on tabs/windows doesn’t display them on the 1650 output, just on the 590 output.

Any suggestions to fix this visual issue? Thank you

As I pointed out in your other thread, the last Fermi drivers do support Pascal. They unfortunately don't support Turing, which is what you have. That's why the 590 is using the Microsoft Basic Display Adapter driver while you have the Turing drivers installed.

Can't you leave a 2nd monitor connected to the 590? It's not like you need hardware-accelerated graphics to click on a few dialog boxes that pop up there.

My mistake, I meant Turing not Pascal as it's a 1650. Don't have 2nd monitor. Hopefully can get my 1650 working soon so I can ditch the 590.
