Hello, so recently I started zCash mining. I have a bunch of older GPU's so I thought I would give it a go. I plugged my in newest AMD GPU that I had, a PowerColor 7870 giving me about 2$ a day. Then soon I discovered that I had a 5850. Soon after I tried to plug it in and hoping it was just plug-and-play, but no. When I first booted up and tried mining one of my cards only showed up. I was so frustrated after trying to fix the issue for 1 week I decided to screw it and start over. I got it to detect the card, but not actually mine anything. It kept giving me "Insufficient data" Or something along those lines.
What software am I using? I am using claymores cash GPU miner
Do I have enough power? Yes I do, I have a 750-watt corsair PSU
What OS am I using? I am using Windows 10 64bit
Anyone have any idea how this issue can be fixed? I mean like it's a mystery I have tried everything that I can think of.
