the firmware and the site nicehash, to smith, the only one I know, with cgminer 4.9, I found 59000 hardware errors, something like 3.5% in 12 hours, so I returned to the official firmware of bitmain, 2015/04 / 15, the power and set to 365.2
default and 350M

I also have a problem with the firmware of your site, the speed is lowered significantly, up to log off, and I found a mountain of errors, almost 3%

I went back to the original firmware, extranonce to me it did not work, I found 52740 errors and s5 was not active, then I do not know if it is normal that I see on nicehash hash values from 1200 gh / s, even down to 256 gh / s, 68 ghs, 620 gh / s

more noise than s5, change fan

Italy we have 220 volts, but I never buy s4 +, price too high,Shipping to Italy high, and high customs fees, praticamento s4 + I pay for 2 times

but fail to produce a car from 10 terash
to 16 nm? the cost $ 1500?

as I said we need to see the costs

what will make them pay for the upgrade kit? 500$???

I had to buy 8 delta fans to see if I can lower the damn noise fan 8 x 4 antminer s5

I do not understand why a return to the old chip, instead of going forward we go back? the price should be much lower, however, and very high, you have created
s5 with noisy fans, and do not even bother to correct the problem to help you, I'm sorry for you, but I've already had a bad experience with you to bitmain, you made me pay 3 shipments x 4 x antminer s5, including 1 s5 was well used, I have not even refunded the cost of your mistake, not even 1 coupon for the next purchase, that will never happen again, because you are only interested in money, and does not meet the customer.

bitmain should send fans of silent to all customers who have purchased s5 with infernal noise

but then again the Chinese by nature and very greedy for money, and with style are born, not made with money lords

I think these s4 + I lower the price I are all in stock

we returned to an older chip, added a +, and the price always very high, congratulations

bitmain could fix the noise problem by sending the fans quiet to all their customers, but it certainly will not do it because the Chinese are too greedy for money

GARANZIA BT venire Posso Attivare su S5 Extranonce abbonamento?

I do not understand how to turn on Extranonce subscription nicehash and if should activate it on my 4x antminer s5

thanks for the reply, I remain with the official firmware
