Back to topic. My batch 2 comes tomorrow.
Orders on 2 and 3 are done.
so if you ordered on the 21st of oct or later have you received shipping info?
no shipping on Oct 16 B2 order no shipping on B2 oct 22 order I am starting to slowly getting wound up about it. I missed most of the day today because of stupid comcast blackout, so maybe it was discussed at length already, but here are my 2satoshis about internet disconnect issue: 1. I confirm that manual setting of fan alleviate the internet disconnect problem as fan stayed up during the disconnect. Incidentally, If you don't have this data yet, any setting between 90 and 65% gave me exactly the same fan speed, which is weird, i know. So, i set it up at 80% arbitrarily as I don't care about sound due to my igloo-like S7 isolation. 2. during disconnect miner was beeping, but fan was at the same speed. 3. I kept miner powered and took measurements as soon as it was reachable. Board temp were in the 40-44C-fully safe (normally they run at 54-55 for me) Cheers

For those wondering if the firmware fixes the issue with not having internet access potentially frying a s7, I can confirm it. My father-in-law was watching my kids today and was having issues with the wireless on one of my Roku boxes. He arbitrarily started setting static ip addresses and knocked two of my seven s7's offline about five hours ago. Both had the new firmware luckily, but one of my seven did not. I killed the port on the juniper switch with the one that had the old firmware and the fan crawled to an idle, so I can confirm beyond a reasonable doubt that the new firmware keeps the fan at a very high idle if there is no internet connection.
I asked him what time he messed with the addresses on the Roku and it was five hours ago. On both of the ones he knocked off before finding a non-reserved IP they were both beeping very loudly, but the fans were spinning at a high rpm. During my test on the one with the old firmware the fan was barely spinning, so for the father-in-law variable the last one is updated now. Hard resetting them both allowed them to recover, luckily I am anal and log dhcp assignment and errors to syslog. It only took me a little while to figure out that he picked addresses that were in my reserved dhcp exclusion range.....
Neither auto-reconnected, which I find to be an interesting design flaw or bug.
Sigh!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Thanks for the information, Sir. Much appreciated! Glad I updated to new firmware then. Can keep fan on auto and not worry if internet goes out a while. I normally don't do firmware updates but I think this one is worth it. The people that hard code their fan settings low on purpose on the original firmware may be in for a nasty surprise. :/ Ufo

And doing it voids warranty...... so expensive machine to void warranty on. So I'm honestly surprised some do it at all. It's almost to the point you need a area to put loud miners. It makes your life so much easier then trying to battle noise.

You have too many conflicting statements, Sir. It's so confusing that I don't know what you are trying to imply anymore. It's just not possible to pull 32,000 watts at 120 volts (266 amps) through a 200 amp breaker UNLESS the breaker is defective.
OK, believe what you will. I do know several "licensed" electricians and had one confirm with me today, after these exchanges, that it is Per Phase on the Main - not total. So each phase can be loaded with 80% load and the main will not trip as they are out of phase and not an addition of current. Here is a list of miners and wattage that I am currently using - all at 120V. They alone are exceeding 200A in power usage - 13 x s7's = 15730 WATTS 8 x s5's = 4720 WATTS 1 x S4 = 1400 WATTS 3 x A2 @ 88 = 2250 WATTS 4 x A2 @ 110 = 4000 WATTS TOTAL WATTS = 28100 @ 120v = 234A The only 240V circuits being used are 1) Stove - 2) Water Heater. Even with the miner loads, I'm still able to use all sorts of other electricity - IE this computer - a couple 1000 Watt gaming machines, a 200 Watt Laser Cutter, air compressors, electric drills, radios, garbage disposal, hair dryers (when gf needs), and charge my Chevy Volt. You are saying this is impossible, unless defective - seems to be working. I'm beginning to wonder if you have a 300 amp breaker thrown in a main panel rated for 200 amps. Also, when you say, "All on 120V," are you using 2 pole or single pole breakers for your rigs? Isn't a 200 amp main at 240 volts? So it would be 400 amps at 120v? Use both legs on each breaker 200 amps max One leg on each breaker 400 amps max Same power/wattage either way Since we are talking power, any way to take two 20A 120v dedicated outlets and make them 240V externally? I don't have access to the panel and only the outlets, but each is dedicated on its own 20A breaker. Just asking, probably not, but worth a shot.

However, the main breaker is designed to trip IF EITHER POLE exceeds 200 Amps; not both.

If you have a 200 AMP Main Service Panel, you are limited to 200 Amps REGARDLESS of whether it's 120 Volt or 240 Volt. A 30 Amp 240 Volt circuit does not take away 60 Amps of 120 Volt. A 30 Amp 240 Volt circuit has taken 30 Amps of 120 Volts [When measured in amps]. The main service panel is limited in "AMPS" not volts! Yes, it's limited in volts in the sense that your main service panel in you home is rated for 120V/240V. Other panels, especially for industrial use, can be rated at much higher voltages.
So, again, your main service panel is limited in amps NOT volts. A 30A/240V circuit does not mean 60 amps worth of 120 Volt circuits have been kept from installing in the main service panel. I will say this: 60 amps worth of 120 Volts has the same power (watts) as 30 Amps of 240 Volts. You could have a 30 amp/120 Volt circuit. However, it would not have as many WATTS (POWER) as a 30 amp/240 Volt circuit. The main service panel is not limited with a measurement in watts. It is limited with a measurement in AMPS. Your amount of watts (power) used in the main service panel will be determined by what voltage or voltages used in the circuits wired to the main service panel.
Thanks for this info. Very informative for me. I'm learning more and more about electrical here.

The difference comes below 65%. i might update the firmware, but someone here bricked the miner by doing so. Why risk it if all it does is make the fans turn and putting 80% in % window does exactly the same thing.

However, the main breaker is designed to trip IF EITHER POLE exceeds 200 Amps; not both. [/quote] That's what I've been trying to convey Wolfen, however technically its not combining the Amps. Each leg has a capacity of 200A. The Main will switch off if either LEG exceeds 200Amps is true - however if you load 160A on each leg you are not Exceeding the 200A per leg. I'm using single pole breakers for the rigs - mostly consisting of 20A and 15A circuits - a couple of 30A circuits run to out buildings. 2 Pole breakers would be 240V no? My service is rated 200 Amps according to electric provider. The main appears to only be 180A on the panel, which seems right because if I load over 170A on one leg the panel gets very warm and will switch off after 30 minutes or so. Load balancing the 2 legs/poles and I have zero issues running the 230+ Amps of rigs and other electronics. It took a lot of trial and error as well as hand-charts to balance the load, but before I had s7's I had 25 s5's and 4 S4's along with the scrypt miners running all summer without issue. Yes the main panel got warm in the summer and I put a fan on it to help cool it down, but circuits held and nothing burned up.

Ouch... that looks nasty. I hope you get your warranty sorted out. Make sure to document everything, which you seem to be doing already. And despite what Bitmain tries to tell you I would inspect all remaining heatsinks before powering them up... something seriously wrong there. Ran out of glue or used wrong glue or something.

Your amount of watts (power) used in the main service panel will be determined by what voltage or voltages used in the circuits wired to the main service panel.
Thanks for this info. Very informative for me. I'm learning more and more about electrical here. I think the important thing is this: One (1) 20 amp 2 pole breaker has the same watts (power) as Two (2) 20 amp single pole breakers in watts (power). One (1) 20 amp 2 pole breaker can pull a maximum of 20 amps ON BOTH SIDES. This is like having two (2) 20 amp single pole breakers [One on each pole] pulling 20 amps on each pole. A Main breaker is designed to trip if there is ever more than 200 AMPS / 24,000 WATTS draw ON EITHER SIDE. When I said on both sides combined earlier, I meant to convey if we have more than 200 amps draw on either side, the 200 amp main breaker "should" trip. Otherwise, THAT pole could get too hot and risk possible melt down of the pole and the breakers connected to it. The drawing I'm including below was done in Microsoft Office Visio. It depicts the guts of a 200 amp main breaker panel without including the neutral/ground bar(s). Notice how I have 5 x 20 AMP/120 VOLT (12,000 watts) single pole breakers on PHASE - A and 5 x 20 AMP/120 VOLT (12,000 watts) single pole breakers on PHASE - B. This comes to a total of 24,000 watts for rigs. Which, is no where near the 32,000 watts mentioned earlier. Something else: I'm not saying to max out each circuit. Simply add another circuit to make up for the same total of 12,000 watts on each phase while collocated with the 75% limit for circuits inside walls and/or conduit. Also, I have only shown double pole circuits for the large consumption appliances for the home, such as, Air Conditioning, dryer and stove top/oven. I have not included a refrigerator, separate freezer [if you have one like myself], multiple televisions, lights, stereos, gaming stations, computers, exhaust and intake fans for getting out the heat from rigs, etc. We have very easily maxed out this 200 amp breaker panel with what I have shown in the drawing without coming anywhere near the 32,000 watts of rigs mentioned earlier. Plus, we don't have the other things necessary in the house like I mentioned. A 200 amp main breaker is rated at what it says, "200 amps." Meaning, if we ever have more than 200 amps on either phase, the main breaker will trip... period!!! I was trying to think of a way multiple single pole 15 or 20 amp breakers could be installed to achieve 32,000 watts WHILE STILL PROVIDING SUFFICIENT POWER to all of the other circuits mentioned, such as a compressor and 1000 watt gaming machines, etc... I just couldn't see a way to do it. If I'm wrong, if someone would not mind taking the time to explain it to me, I would appreciate it. Here is the drawing:

Run all single pole breakers on one leg and it is done. Hot through load to ground. I was confused, I run all two pole 240v circuits so it automatically balances.

Wow that looks really bad. Could've burned down the house. Sorry to hear about all your troubles and I hope that Bitman comes through for you. I wonder if it would be better to run these things on the side so that gravity doesn't pull down as much on the heat sinks.

Yes the main panel got warm in the summer and I put a fan on it to help cool it down, but circuits held and nothing burned up. [/quote] Will you take the time to show me what you did to balance? Maybe I'm about to learn something. Don't forget, you have 2 pole breakers for A/C, Dryer and stove top/oven. Also circuits for fridge, lighting, etc... Unless you did not use 2 pole for those appliances and used 2 single pole instead. You can draw it on a piece of paper; take a photo of the paper and post the image here. Maybe we all will learn something.

Ouch... that looks nasty. I hope you get your warranty sorted out. Make sure to document everything, which you seem to be doing already. And despite what Bitmain tries to tell you I would inspect all remaining heatsinks before powering them up... something seriously wrong there. Ran out of glue or used wrong glue or something. Thanks. I have asked for permission from Bitmain to allow me to remove and inspect all hashing boards before proceeding any further.

Only thing funny is photobucket offering prints of photos.... i doubt that is a memory you care to mount on the wall. Most likely I bet Bitmain say's no and asks to ship it back looking at the damage. If they do surprise me and let you open it up please share.
