Very sorry for the noob mining question really apprecaiate the help in advance. I have looked under devives and looked at the PCI its under and what its listed as but still seeing to have a problem/dont understand thanks alot guys.
Good question! I faced this challenge too when building and tweaking my rig.
Here are a few steps to make your life easier:
1) arrange cards physically and connect them how their risers are connected on the motherboard (the card on the most right will get the riser connection to the pci-e slot on the most right)
2) activate and connect each cards from right to left until all cards are connected (if using windows as you connect one card you will need to reboot each time).
3) once all are installed and recognised in device manager start tweaking with Afterburner.
4) Start with all cards on default setting and run your miner program.
5) overclock one card only and see which one sticks out (will give higher perfomance, temperature and hashrate).
6) label that card with a number
7) return that card to default repeat steps 4-7 for subsequent cards in your rig.
