@Storx: did you get any more granularity on the intervals? Seems strange you were getting best results with 3000 (that's 50 minutes without switching)...

Im sorry bud the test was spoiled by thunderstorm a few days ago, my parents house which has 2 rigs, 2 racks of 4x1080ti's per are down.. still troubleshooting the issue.. seems the motherboard is fried.. really hope that the 8 GPU's are ok...

currently im mining at 10minute intervals, because it seemed switching to often was causing a lost in profit due to switching in the middle of processing data, but going to long was pushing out off the clif of income.....

That's a damn shame, talk about luck. I hope your 1080 ti's are okay!

My condolences also.
Did you use surge protector on your rigs?
I am still unsure if surge protectors are worth it when it comes to thunder hitting nearby electrical grid.
Theoretically, decent PSUs have surge protection, so maybe its just your PSU that is dead?

Ya i had each rig on UPS brand backup power supplies, the UPS is still working on both and when i turn the PSU on manually the GPU's turn the fans.. but the motherboards are not responding at all... im thinking the damage came through the internet cables, because it took out the cable modem as well.
