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.
