Who else have overclocked their a3 miners / at what and how is it performing?
I ran some tests, posted here:
https://bitcointalk.org/index.php?topic=2881452.0. I'm sticking to 681 as I'm taking advantage of cool ambient temps (miner next to an open window) and my HW error rate is a bit lower than it was when I tested.
I've been mining in SiaMining, but switched over to Luxor today to give it a shot now that their luck has been improving... I'm going to give it a few days before making the call on switching back.

Update, just switched back to SiaMining. Ended up giving it almost a whole week (~6.4 days) but ended up averaging only 1,409 SC/day on Luxor (and I'm overclocked at 681, hashing average 940GH/s in Antminer UI). They had a day or two with solid luck and enjoyed that payout, but there has been much more bad luck than good. Maybe I'm too impatient to handle 10+ hour timeframes with 0 blocks found but that's a bit tough to stomach when there's a month left before the second batch ships and profitability tanks. They did mention that along with their "24-hour ramp-on" that there is also some sort of ramp-off where I get paid for 24hr after stopping, so I will update this post's figures with the additional revenue (if they find another block

)
I was netting 1,900 SC/day on SiaMining before I switched over, the diff has of course gone up so I'll also see what I end up back at once I've been live for a day or two.
