2 Different Nvidia cards in one PC

[Enzo1001]

Hello everyone,

 

I have 2 monitors, one is connected via DVI and the other via hdmi, i recently decided to upgrade to a gtx 970, since it doesnt have an hdmi port, i decided to throw in my old gt 710 for my secondary hdmi monitor.

Now my issue: When i install the driver for my gtx 970, my secondary monitor wont work, and if install the drivers for the gt 710, both monitors work but everything is super laggy, since the gtx 970 is not used, and its not showing up in task manager. 

 

How can i have the 2 different drivers installed at the same time?

are you plugging the monitors into the correct gpus or bothering to clean out the old drivers or are you just piling the drivers on top of eachother

run both monitors off the same card. DVI to HDMI adapters cost only a dollar or so.

I just picked one up to run an older 23" HP 1080p screen as i wanted to have somewhere to dump all my open webpages and  links for my Eve Online escapades.

Trying to run two sets of drivers is simply going to create conflicts even if you managed to install both which is highly unlikely.

get a passive DVI-D to HDMI adapter

you understand an operating system has more than one driver installed at any given point correct?

To clarify DVI monitor is pluged into the GTX 970

The HDMI monitor is pluged into the gt 710

Is it the Fermi or Kepler GT 710? If you don't know, use GPU-Z and under "GPU" it should say GF119S if it's Fermi and GK208/GK208B if it's Kepler. 

 

And which GPU driver version are you using? Kepler needs a fairly old GPU driver, Fermi needs an ancient one.

yes I understand but for example  GTX 970 wich use Nvidia driver 353.06 and an older GTX 280  uses driver 341.44.

Installing one set from nvidea simply overwrites the other.

Nvidea control panel you can select alternative GPU installed and select one specific for Phys X but it has been known to slow down the faster card if selecting the slower one for such tasks.

One can also simply look to the device manager and select GPU adapters and select the older card for a generic driver to avoid the issue on a newer Nvidea driver software set over writing an older version.

Personally I would just use the fastest card and buy a dirt cheap adapter plug. I purchased one only last week for a Dollar here in Asia. USA as low as 2.50 USD
