Re: Bitmain's Released Antminer S9, World's First 16nm Miner Ready to Order

Ive got three gecko usb sticks that consistently pop up with 18Ghs (set to 12ghs) but they don't reach it regularly, infact they often drop to 8-9Ghs (even though still set to 12Ghs). That's why you have an average hashrate (which is the only one you should be worried about). The next 5 min hashrate could only be 10Ths on your machine so it evens out.

I understand about the average hash rate.  What I am curious about is what is happening to the miner that raises the TH/s that high, even though its only 5 minutes and drops back to average.  I have a no fluctuations in electrical current, so what internally is making this happen.

I was hoping to get more feedback from the master electricians and hardware hackers.  What I am hoping is that if the machine can run at 20.03 TH/s for 5 minutes, then should I not be able to find/duplicate the action causing the spike?  Even furthermore, once found should you not be able to keep that action stable?

I also see in my Kernel Log that is showing two odd errors-

"Test Patten on chain[3]: FAILED!
Try to add 0.1V on chain[3]..."            

"Below ASIC's core didn't receive all the nonce, they should receive 8 nonce each!

asic[12]=908
core[058]=4   

asic[38]=910
core[023]=6"


How would I add 0.1V to board 3 and why do asic 12 and 38 not receive all the nonce?

Thanks for the help in advance!
