My pacmic v4 just finished will save all btc if they do a v5

Do you guys in the states have to pay an import tax?
I bought 2 x ANTMINER S7-LN with power supply
had to pay extra $185.00 in import tax

No they don't! Wonder why they are so much in debt.. http://www.usdebtclock.org/ xD

How do you make a payment in BTC in less than an HOUR?
The entire network has not found a block in
Network: 66m (416434)
please explain
I have a payment thats been status ? for 3 hours now and mid setting on confirmation time.

Running S7s in my garage since summer started. Considering S9. Couple basic questions for those who have run both S7s and S9s:
Is the S9 louder than the S7 (same, little louder, much loader)?
Do they put out about the same amount of heat?
Will they run reliably in a 90F ambient environment?

Hi again guys!
Just ordered a sample of the S9-B3, and obviously the transaction did not get confirmed in time, so my order expired. (Payment sent from Trezor wallet with highest fee possible.)
Do you guys think I need to make another order? Or will Bitmain fix this tomorrow? I don't think its possible to get a transaction sent from a trezor hardware wallet confirmed within an hour..
Also just spent 2 hours signing another transaction.. guess I shouldn't mine to my trezor address!

...Power consumption at the wall is 1.37 kW (0.99 J/GH) for the S9 with 13.82 TH/s and a total of 5.06 kW (0.096 J/GH) for the other four totaling 52.58 TH/s. Power supplies used are a mixture of the 90% and 93% efficiency DPS1200FB types, ...
Hey, this is pretty great - actual factual <0.1J/GH at the wall! That's been a long time coming, and is just about 100x the efficiency of the Avalon 1s. Hash rate per volume is around 400x since the Avalons were so spacious inside.
The rest of your news isn't as great of course. The low hash rate you see on m6 and m8 - is that happening without HW errors? My initial o/c tests showed a sudden drop in hash rate around one or two notches higher than 650, but with no HW errors, no x'd chips, and generally no indication of error.

seems like batch 1 got the best deal if you look at USD instead of BTC prices
Except I can't mine USD so batch 3 is the better deal. ~3.1 BTC and apparently will arrive before batch 2, which was 3.4-ish BTC. Another half BTC drop and I might consider a couple.
June 15, 2016, 12:39:04 PM
what was the prices of batch 1 & batch 2?
2100 + shipping
1985 + shipping
I have exact figures give me 1 minute
seems like batch 1 got the best deal if you look at USD instead of BTC prices
unless you purchased enough coins for 4 from batch 1 at 550 a coin.
then got scared when kano siad the s-9s may not mine on his pool.
I grabbed 2 s-9 batch 1 then held coins and got 2 batch 2 s-9's
I paid 6.6 btc for my batch 2.
I paid 8.1btc for my batch 1.
I paid the same for the coins so I saved 1.5 btc now so far my batch one have mined .05 btc so I have a race to see if the batch two show quicker then it takes for the batch 1 to mine 1.5 coins.

Yes, I suspect your method also reduces the overall noise level due to the filter in the front. I am going to try it. Jbbtc

your methods will work. I used to try some like that.
I do like the filter method I listed above.
12 filters for 4 usd and a roll of duct tape lets you do 12 s-9s for under 10 usd.
the whistle stops and much less dust goes into the gear.

Hello, The whistle on the S7's (my B2 s9 ships next week) is caused by an organ pipe effect in the air columns formed by the metal grill. It can be interrupted and largely silenced by a strip of duct tape along one edge. Experiment to find the optimal position which doesn't restrict airflow significantly. A better solution is to remove the grill completely but as these fans can remove a finger, don't do this unless the entire miner is in a sound insulated box and the front fan cannot be accidentally touched. As the S9 has the same fans and configuration as the S7 I expect this solution will work there as well. Also, I have replaced the front fans on my s7's with a delta fan described as "the beast" in some ebay ads. It has a top speed well over 5000 4pm and draws too much current (probably--who wants to risk it?) to power from the controller.)I power it using an extra pcie connector but keep the original connection to the fan connector for the speed control line and the tachometer. The miners have been perfectly happy at 98F in my garage with a little underclocking.

Also note that it has the same # of chips as b1 (189) but runs at a lower clock of 600MHz. Looks like Bitmain decided that the b1's were actually now what they consider as OC'd... Their way of addressing the high chip temps?
Und ja, I ordered 1 of the batch-3's.
Oh, my b1 miner seems to have settled down in it's new home and the overnight avg hash rate as reported by Kano is 13.5THs and checking just now is holding at 13.7 average on the gui. Much better than the barely 13THs it started out at.

I did your fix using vent filters on the intake side.
http://www.lowes.com/pd/WEB-Web-Vent-Register-Filter/3122205
duct tape.
http://www.lowes.com/pd/3M-1-88-in-x-135-ft-Gray-Duct-Tape/3505480
99% of air gets through .
quite a lot of dust is stopped.
and no train whistle.
under 10 bucks and will do 12 s-9's
625 freq is giving me about 26 to 27 th.
temps are 65-90
earnings are 0.03175 so far.
Hi Philip, can you show the pix for - vent filters on the intake side?
3 of my S7s suffered because of dust problems - hate to have that on the S9. Thanks
I am going back to solar array in a few days but I can do a mock up for you.
shot before filter
this is mock up.
red electrical tape not duct tape
white piece of felt not 4 inch by 10 inch vent filter
and the fan is wrong a silverstone 141 not a bitmaintech tech.
of course a card board box the fan is on is not the s-9
but this is the general idea in real life the filter is long like the fake photo but pretty much is perfect fit height wise
