Hi all,

Long time no see.

Performance improvement on Nicehash


We have shipped a test miner to Nicehash and opened source to them to help improve the performance of A4 on NH. We will let you know the update.

Hello Innosilicon, what is the update from Nicehash? What settings should I be using suitable for Nicehash? Thanks



It will be interesting to see what they come up with, I have contacted Inno and them about the drivers, I guess I am glad they let someone look at it, I was hoping to get a shot but oh well. I updated my boards to B3 myself and was hoping for a better luck, which over all they are better but still not good. I have went and patched the cgminer binary, for some reason no one has been able to tell me was why the cgminer took so long to run if you just started it, turns out there is a sleep(9) first thing in main, why is it there , who knows changed it to a 0 and works just fine, got wondering why ./cgminer --help took 10 seconds to run.

Another thing is the reboot on slightest problem, I changed the /sbin/shutdown binary to just do a sudo pkill cgminer, the only thing is you have to run cgminer command line and in a while loop but it restarts, but normally when it dies like this you have one more more hash boards that are going to act up ... so the next thing was to solder a wire to the MCU reset and tie them to a pin on the rPi that hardware resets them as well, seems to help some but still testing..

Only being about to poke around in assembly is a real bummer, unless there is just a simple answer everyone has overlooked I wonder if it is going to be easily fixable, sure it will mine LTC and other slow block coins one at time.

I just wish a bit more thought had went into some of this, I wish you could specify the voltage per board not as an over all, most of my units just need one board to have a little more but when you do them all you are wasting some power on the others.
