Re: [ANN] US/North American Bitfury sales NEW STOCK ***NOW SHIPPING***
^what about price adjustments in the MBP store?
lulzdouble lulz,
We have 3 pages of cost adjustment questions and we get a reply about where he is going/meeting. With the btc price low now, antminer is better choice by a huge margin. 400 for 35gh +controller or 750 for 180gh standalone machine, tough choice right?
Aside: Hmm - so why does my BA fury board do 40.1GH/s paid to the pool?
What's up with the ones made by the guys here?
(or is that something to do with my cgminer driver?)
Yes these are real questions ... I've only had access to a small number of BA fury boards and basically no access at all to the boards listed here.
So I've no idea if my driver needs more work to support a lot of boards (yeah there really isn't much CPU power in an RPi) or if something else is going on.
I guess I need to spend some time on a large BA fury setup and work out what's going on with these crappy performance figures reported for the hardware here.
Then once I'm sure cgminer performs well with lots of boards, then the question here will be why on earth the boards here are rated so low.
What voltage do the BA boards run at? My best MBP boards can get just over 40GH when the weather's cool. But the main bottleneck seems to be the voltage regulator. Most of my boards are overvolted to around 0.86v, and the speeds are set just below where the regulator would cut out due to overcurrent/temp. At 0.86v, they could usually be clocked higher before getting too many errors, if it weren't for the current limit. I can determine that by turning off a couple chips and clocking higher until the errors start. Do the BA boards have a higher current limit than 30A?
