Thank you for your reply.
I got it, I am thinking something is strange as I was not running it overclocked, it was actually under the factory settings because I want a more sillet machine and anyway it happened, I will try to put factory firmware later and see what happens.
Another thing, are you on stock firmware with those D3s? Does hardware change from one to other? I'm not sure but maybe they only find sweet spots to run higher as we try to do.
If anybody has more hints.
First of all, thank you Blissz for the work. My first message here at bitcointalk, cheers!!!
Is that normal having a hashrate of one board disappearing and coming back all the time?
The power usage still same when it happens but as I am mining in nicehash and when I see there is a decrease in hash rate also on their dashboard, what can it be? I am running my D3 at about 9500Gh/s(only two chains) as I am using a pc PSU while they ship APW3++.
From what I was told by a buddy (maxumark) you just have to set the speed down to where it is stable...took him 2 weeks of mucking about with it
thus my 1st batch I get a 'fairly' regular 16gh with no errors
remember the orig batch was supposed to be 15gh (they overclocked it and said 17.2gh)
the batches after were then supposed to be 17.5gh (they overclocked it to 19.2gh)
so I have one 2nd batch doing about 19 and 1 1st batch doing 16 for 35gh or about what they were supposed to do in the first place ..stable ...for a total of 35gh
maybe this new firmware bitmain released helps ...not up yet on my stuff
also they get about 2100 watts at the wall combined not 1900 watts as bitmain states
so it goes
