I'm not SLI'ing them.

It's still not supported.

Welp, it is in an older driver apparently.

Either way, you are the first person to say this. Ive seen on countless forums that running 2 different cards (one for physx and one as main) is perfectly fine.

AND

I have an AMD HD 7750 that I can plug in and it'll work perfectly fine as far as mining goes, and it detects both cards in device manager.

What you're trying to do will work fine if you used a GTX 680 and 670 or 680 and 660 or 680 and 650. Or if you used a GTX 960 and 970 or 960 and 980 or 960 and 950.

 

It won't work if you try to use a GTX 6xx card with a GTX 9xx card at the same time.

Hmm.

Well, this still dosnt explain why my HD 7750 + EVGA 960 FTW work together.

Let me clarify what i mean when i say "work together"
1. Both cards are detected in device manage
2. No error msgs on either of the cards in device manager
3. I CANT use the 7750 for physx BUT using it to mine works perfectly. Ontop of that, I can use both the 960 and the 7750 to mine at the same time.
Edit: #3 is honestly the main goal im trying to accomplish hear. I guess i would have to run 2 systems? I'm only doing this to benchmark kinda and its sorta interesting to me and i've made like $10 mining with my 960 xd.

wait..
i guess its cuz i.. had to install drivers for the 7750..

Im confused, but what you said did shed a bit of light on the subject. Ty, I was being naive...
Now, work around?

Btw, would you mind linking me to something that specially says this? just so i can confirm that this is for sure true.. Genuinely curious about it.

I don't see how this isn't supported. We have been able to use two different generations for a long time now where one card is being used as a PhysX processor.

It's a computer!

Yeah, this is what i thought aswell. I mean im pretty sure ive seen someone doing it..

But on a side note maybe its true?
Reinstalling the 960 drivers, 378.92 i think it was, clean install and everything didn't fix the issue. Im about to plug in the card by itself in a min.. once windows decides that its done updating.. :T

Edit:

I alao just read this on toms hardware:

"...two different cards, not bridged (not working together) will require drivers that might conflict, as well as outputting two completely different images, the monitor can only show one image. Two graphic cards can work if each one has it's own monitor to power up, there will be no conflict between the graphic cards..."

It was marked as the solution on the forum i read this from. This seems a bit strange tho, i dont know why that would matter.
