I bought an ASRock Z97 Pro4 motherboard for a new mining rig and failed to notice that it has 4 PCIe slots and 2 PCI slots. If I’m using the molex powered 1x to 16x PCIe risers, can the regular PCI slots still work or am I limited to 4 GPUs with this setup? via /r/BitcoinMining http://bit.ly/2rY8xsy
