Perfect, thanks for sharing, sikke. I think I agree that 1600 doesn't seem worth it at that rate. I'll go ahead and try mine and see if I might have a "luckier" system (probably not, given my luck). I'll also try 1550 if I can get it to take that. I did do a little --avalon-auto this morning and it seemed to alternate between 1450 and 1500, so I might have a shot.
My --avalon-auto got stuck at 1499 in that unit and also 1550 didnt stay stable hashing. I'm pretty happy with 1500@230GH/s i will continue going trough refurbishing all my units to that spec. i still have work to do with fuses and so. i want to get all out from these.
