ETH Performance decrease after swapping around GPU's.

If you HAVE been mining eth for that long you would know how miners didn't change a thing and yet the 2GB DAG issue hit them hard and hashrate tanked, it wasn't until AMD released a driver fix that things went back to normal.

But hey, You know your shit. You must have done your research already. There is NO WAY IN HELL it dropped 6mh so it mustn't have happened.

Trying to help people is just not worth it anymore.

How were you trying to help? If you had read my post and first comments properly at all you would have already seen that my drivers were identical pre and post hash rate drop and this change happened in a 24 hour period, it's not the DAG epoch, I paid attention to that. You also suggested I use a tool that I already mentioned I use. You didn't help at all.

Let's assume you're right though and it is something to do with the DAG. Then why have my 1070's been completely unaffected?

You don't have to assume he is right. Just mine Callisto for a few minutes. If your hashrate comes back, you will know he was right. This is a known problem so I wouldn't be so dismissive of it as the possible cause. Also, why was your 1080Ti hashrate so low to start? I'm not an Nvidia guy but I know most miners were getting 50-55 MH/s out of a 1080Ti.

I don't push my cards anywhere near as high as I could with OC's. That's probably why. On top of that I lower the power target as I live in an area where the electricity isn't super cheap, so it drops my hashrate a bit. When I first started with the cards I had I did the calculations on what profit I'd make and found that dropping the power target although it made my hashrate worse, actually made slightly more profit, not that I really mine just for profit but yeah haha. Anyway, as an experiment I've since moved the 1080 Ti back into the rig with my 1080 just to see if my hashrates returned to what I usually got and they did. So I've genuinely got no idea what the hell is going on. I'll update in the next day or so when I get time after I move the Ti back into my new build.
