Can I use 4 Radeon GPU with this mobo? Crossfire

[unusual41]

Hoping someone can help me.  I have ASRock 970 Extreme3 R2.0 AM3+ AMD 970.
Can I use 4 AMD Radeon GPU with this mobo for mining?
It has 2xPCI Express 2.0x16slots + 2x PCI Express 2.0x1 slots. I have "16X to 1X Riser Card Adapter Extension Cables" for utilizing "PCI Express 2.0x1 slots".
Can someone help me?

I highly doubt you can, you already seem to have trouble using the search function.

Make sure to use powered risers, or use a motherboard with an extra molex input to give the PCI slots additional wattage!

I still waiting for straight answer.
Can I or not? I have 1050W PSU.

The motherboard manufacturer's website says it supports quad crossfire. How is that ambiguous?

Quad crossfire could be done with 2x Radeon 7990 which have 2 chips each, so I think it is indeed ambiguous.

Crossfire is totally useless for mining.

Do not use it if you want to mine.
