Thank you, appreciate your help. I run ccminer lbry with default settings, no overclocking of gpu. I didn't see any settings for temp, How can i lower the temperature ? Thx in advance!
Load up afterburner and set the power limit to 75-80% and see if it has much of an effect on your hashrate. I think you'll find you only lose a few percent, but the temps will run much closer to 65-75c. Overclocking can shorten the life, but I think it depends on the temp more than anything.
I think you basically covered it, I guess the question for miners now is (other than what coin), do you go with 4 1080s (or 3-4 1080ti) or 6 1070s.
What can your motherboard handle is important also, I'm leaning toward 4 1080s, I just don't know if it's worth it to go with 4 1080ti...
I'd say that if power costs are a concern I wouldn't go with the 1080ti's They will run a good 250W each so you'll need a big power supply for them. The 1080's are going to run more like 175-200w at the top end. Other thing is the 1080Ti's will likely hold above the $500+ resale value for a good long while, whereas I'd expect the 1080's will be closer to $350-400 after about a year, maybe less if mining dries up. Either way you'll likely have the cards paid off in 2-2.5 months of mining at current rates.
I'm running all mine on Windows 10, but that's just because that's what I had handy. Not sure if the OS would affect my rates that much or not. I might try reloading one with Win7 and see if I get different results or not. I might actually try Linux too since that is likely much lower performance requirements and I could easily put that on a thumbdrive and try it out.
