Is there any way to combine two graphics cards vram?

[MartinIAm]

I have two graphics cards. One is a gtx 1050 ti and the other is an rx 570. They both have 4gb of vram. Is there anyway that I can combine both of them so I can use that 8gb for ai model training?

 

If this is at all possible, but needs the same brand for the card, I also have a gtx 750 ti which also have 4gb of vram.

No, it's not possible.  Unless the software can detect both cards and run some things on one card and other things on the second card.

Technically if you just put both cards in the system, they are both recognized as having usable VRAM and at least in games they can both be utilised. (It worked with a 1gb Radeon r9 and a rx 560 for me) 

I believe they both have to be the same brand for the drivers to work properly.
