Starting to sound like a lot of reliability and DOA problems out of the gate. I guess that is to be expected with a rig that is a lot more complicated than the previous ASIC's. But a little worrying. Mine should have arrived at my hosting location but not online yet. Keeping my fingers crossed no issues.
These e3 miners have been running for 12 months already, the f3 much less, 7 months. Bitmain knows some are broken and yet shipped cause they know users will keep them even though it has problems, now bitmain gives a imaginary voucher for whoever got a broken e3 or malfunctioning, money wise bitmain will never give anybody back. So there you go, perfect business plan, mine with them for 12 months, send to suckers and in the end suckers got sucked even harder hehe
Even though it has problems, the e3 roi is at moment 240 days, rx 580 roi, 600 days, so the e3 at moment for eth, is the best you can get.
