soo its quite safe?
I've been running at 310 since I got the thing. SHOULD be fine, but keep an eye on your temps (note I am not endorsing, just sharing my experience).
Been mining at 494, trying to keep the error rate down on bank 0. My avg hash is 287 kh/s. Are you banking the coin? temps always below 60 on the chip usually between 56-58 unless I close the door to that room.
Yes. I've been mining ETN from the beginning and I've held everything. I like the direction they're taking, they're one of the few making efforts to be an actual usable currency IMO.
