GT 1030 and GT 520 in one PC

Hello,

I want to use the GT 1030 as main graphics card/gpu and the GT 520 as an HDMI/audio solution to try this out.

So I stuck the GT 520 into the PC as well. It has two PCI express ports/slots (winfast motherboard NF4SK8AA (or similiar))

Windows 7 ultimate edition 64 bit is not detecting the GT 520 at the moment..

Only the GT 1030 is detected and working with installed driver.

The installed driver is currently:

417.35-desktop-win8-win7-64bit-international-whql-rp.exe

(Older drivers are available online and on my system, however they contain some security issues).

I have run two 7900 gtx cards 512 mb in sli mode in the past but these got to hot.
These only required a single driver and was easy to setup.

The current experiment is not so much about increasing graphics performance but using graphics cards for different purposes.

It could also be handy for dual-monitor setup or cuda debugging.

So it would be nice if the current driver would work for both graphics cards.
However perhaps this newer driver does not support GT 520 anymore.

I am unfamiliar with how to setup multi-monitor/multi-graphics cards solutions.

Would windows normally detect both graphics cards out of the box ?!

Or does it require special driver installations ?

Does it require "two graphics drivers to be installed or just one" ?

Also perhaps I need to disable something in the bios, perhaps SLI ?

Or perhaps I need to tweak some setting in bios.

Or perhaps I need to fall back an older driver to make this work, but that would rule out this experiment cause I don't want to risk security issues via browsers/opengl/webgl hacks and such.

Very maybe a reboot might help but I doubt it.

Any ideas how to proceed and diagnose the problem ?

I am kinda surprised that windows 7 doesn't auto-detect the GT 520 usually it would detect at least something.

Perhaps it's a winfast motherboard issue ? Unfortunately I cannot really try an other operating system at the moment cause of bad cd/dvd drive.
This is a lesson learned though. It's usefull to install multi operating systems though when buying new computers in case "external boot devices and such" fail Though I am not a big fan of multi-boot and such... bit risky also to run linux on my harddisk for example, so for now... hmmm rather not..
Fortunately newer hardware has all kinds of boot options (for now) but useless for me for now... I tried booting from flash sd but I don't think winfast supports this unless a bios update or something is done... this would need new bios firmware which doesn't exist as far as I know.

I also "invented" a nice trick while cleaning my pc to install second graphics card.

I use a little soda-stick... which is normally used to suck up coca cola and such... and attached it to my vaccum cleaner to suck up dust from hard to reach places ! =D Quite an invention... will google later if a more mature device already exists lol... I would expect so =D LOL.

Please advise with any advise you can give to get this second graphics card working on windows 7.

Bye,
Skybuck.
