Motherboards with a single pci-e x16 slot added with aapte gong to x4 or x1 slot

[Lotus47]

Hey guys i just wanna ask if a motherboard with a single pci-e x16 slot will work if i buy an adapter for pci x1 or x4 slots and install to my board. ?

After i install the adapter will it be working if i add another video card to that adapter ? (Pci x4 or x1 slots converted to pci-e x16) so that i can put another vdeo card with a pci-e x16 slot.

Im thinking about crossfiring a board with a single video card slot which is the pci-e x16 slot . So im just wondering if i buy an adapter and put it on my pci x4 or x1 slots that will convert into pci-e x16 slot .

Will it work if i installed another video card in that adapter ? Im planning about setting my pc for dual monitors.

Here are my specs:
Case: tecware edge
Mobo: MSI A68hm-e33 V2
Processor: amd a10-5800k
1st Video card: rx480 radeon
2nd video card: rx480 radeon

Opinions, comments and advices is highly appreciated thanks

It will not work. First of all, that board does not support Crossfire. Second of all, even if it did, it would stink because of the choked-off input to the second card. The board has
• 1 x PCIe 3.0 x16 slot
• 1 x PCIe 2.0 x1 slot
• 1 x PCI slot
