Setting up a four GPU altcoin mining rig using a nice Gigabyte motherboard I picked up on craigslist the other day.
This motherboard has five PCI e slots which makes it the best board I have in the house right now. My second best is a 3 PCIE motherboard.
I first started out with a single graphics card directly in the first PCI-E slot and fired up the computer. I let Windows set up the drivers and do its work before restarting the computer.
After it was fully rebooted I shut the computer down again and installed a second graphics card on a riser. Then I booted up the computer and let Windows find the card and install the drivers.
I use MSI Afterburner to see if the card is installed and working properly. This program gives me a lot of data on the cards.
I did the same thing until I had four graphics cards installed and running.
Sometimes Windows will shut off the display and you think the computer has crashed. This is normal and I see it a lot. Just let the computer work for a while and generally the display will come back on again.
Once I had all four cards installed I turned on the fans to high speed in Afterburner.
Then I started my mining program and - wow - all the shares I was getting!!
It was so awesome to see so many shares all at one time. Each green line is another share found.
This is really exciting.
I need to buy another card and get it mining on this motherboard with the others. I am going to keep this mining rig running with all matching cards.
Thanks for watching.
