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.

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

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.
