Hi all

 

Hope you're all well. I need some help with my SLI multi-monitor set-up.

 

So some background first, I'm running the following...

 

i5 @ 4.5mhz - very stable

2x gtx670 in SLI

16gb ram

256gb ssd

Windows 7 64bit

3 asus 1080 ws monitors

 

I run a dual boot set-up with Win 8 for games and Win 7 for FSX/P3d. SLI is mainly for the games in the Win8 boot, I've never seen a great improvement in FSX with the two cards. When I set the system up as an extended desktop and then run FSX full screen I invariably get a system crash. When I disable SLI and run three independent monitors I don't, but of course I can only run full screen in one monitor.

 

When it crashes there's no "record" in the admin, just the re-boot errors. I've investigated and eliminated the following so far...

 

power supply - 850w, should be an issue

drivers - tried a few different ones and doesn't appear to solve the problem

disabling fsx from using SLI in the nvidia drivers or inspector doesn't solve the problem, but I am a little uncertain exactly how that successfully can be done

 

What I would love to do is keep the SLI set-up but somehow disable it for FSX and use it for P3d. Any ideas would be really appreciated as I find full screen 3 monitors to be much more immersive.

 

Thanks

JJ

 

 

Not much love here I see  :lol:

 

For future generations, I found a fix that worked me me, so far....Nothing is ever certain when it comes to PC's!

 

The latest nVidia drivers now allow you to use the 2 graphics cards differently. You can either have the traditional SLI setup with the 2 GPU's working together to compute and display OR you can have one card do the normal work and the other dedicated to PhysX. I've done the later, FSX doesn't use PhysX, so I have a nice stable dual card set up.
