Topic: ANTMINER S7 is available at bitmaintech.com with 4.86TH/s, 0.25J/GH - page 156. (Read 527808 times)

It's well within the spec of the chip, so it's all just down to cooling. Trouble is you only know the temperature in the middle of the board. So my concern would be what the actual temperatures of some of the chips that are getting less cooling are going to? With the "Right" cooling it should be ok... but there would be a much less margin for error.

I know what sonopan is but what is "bam?"

Beside the chips heating up. Do you think there's any tear on the circuits itself that would make the unit wear off too quick?

Because at this level of gain, i'd just build it an enclosure with an air circuit that goes strait outside with sonopan and bam. Run the fan full speed with no noise.

I just noticed, he has five (5) pools in the miner status.  I didn't know we could have more than 3.  Is that with the new firmware or what?

LOL, agreed...

Might have to have a mechanism to provide a steady mist of hydrogen while he's at it in order to keep them below 80C.  LOL

Only kidding around...

Yes, I'm like you.  I wonder how long it will last?  

Anyway, THAT is some serious mining there with the S7.  Can't be done without increasing the voltage.  Great job!

Yes very nice, that's more like the sort of Overclock that we should be seeing. 

Technically according to the BM1385 Data Sheet with 12.8V you should be able to run 775MHz giving 6278GH/s  Although I would want the fans running flat out for that...

True, I have an old friend I used to work for who is a Master Electrican (certified).  All of it was commercial work.  I was only an apprentice then and took classes at night.  Did that for almost 3 years but quit shortly before taking a Journeyman's test to get a Journeyman's license.  All of this was in the late 1990's.  If you don't use it, you lose it.

I'm sure I could still do a large portion of the install myself but I would still need his guidance at times I'm sure.  I'm hoping the Contractor he and I worked for [He just retired about 4 months ago they said] will be able to contact him to give him my telephone number.  I'm going to call them again Monday to see if they had any luck.  They said they are not allowed to give personal phone numbers of employees or former employees.  So, I have to rely on them passing my number to him.  If that doesn't work out, I have to go with a contractor that's insured, bonded, licensed, etc...  I'm NOT paying anything up front.  

If I can find someone who is certified to guide me with what I should purchase and do's and don'ts when installing it, of course I would prefer that route.  However, it's still important to have a work permit issued for the job.  Also, the power company will not hook it up to the new upgrade if it has not been inspected [Has a green tag on it].  But yes, I would prefer to purchase all of the equipment myself and install most of it myself.  I just need to know [From a master electrician] everything I would need to purchase for the job.

Holy Smoking HOT!  That is really pushing it.  Keep us informed if you have any issues.  You are getting COIN right now and I hope that you can continue to get COIN later! 

i understand where you're coming from, but then i guess i miss the point of having an electrician. If you're going to go to all the trouble to research everything anyways (my time is worth something to me), why not just do the work yourself as well. Unless you need it inspected. Even then you could do 90% and have a certified electrician do enough to get the inspector to sign off on it.

Hw errors go up and you can't reach those kinds of speeds.

Those are great numbers across the board.  I am curious, what happens with your hardware error rate if you overclock but don't overvolt?

Weird, it works for me. (I just tried and got a bitcoin adress to send to)
Try deleting your shopping cart then retry.

Cool, keep us updated. Maybe start a thread about it? I'm sure a lot of us would like to see your project evolve. I'm the same way, I don't rely on others unless I know I can trust them. I'd investigate everything before contacting the electrician also.

Well usually you would go out and buy what your electrician needs to install, if possible.  Or else he goes out and buys it, but why pay someone to shop...and research wires, if you buy wires, most big hardware store sell "recycled" wires (the ones where they cut it for you), which your electrician is not allowed to install in your walls.  Also for the "clips" to hold wires together, get the plastic ones, hardware stores sell metal ones, but they arent good for normal wires.  Basically dont ever take advice from a big box hardware store worker, they dont know shit.

I don't have an electrician I'm "buddies" with.  How am I to know if they aren't wanting to choose the route that makes them more money instead of going the route that saves me money?  I'm sure many electricians who over charge customers who are "ignorant" probably say, "Ignorance is bliss."

Sure, I'm going to tell them the load I need but also let them know I want to see prices on the hardware for both scenarios I mentioned to see which is the cheapest route.

wouldn't it be easier to tell your electrician your expected load and let him size it. save you the trouble of all the research. it is after all what they do for a living.

I stayed up to read the NEC till 6:30am this morning.  I slept until 2:30pm.  It is 3:30pm now.  

I do not see it written like what prelude provided regarding the "feeder to the breaker.'  However, I do see many references of "...marked 100%."  So, I must conclude 80% is the rule for all Main breakers and other breakers installed in the Main Panel or Sub Panels unless otherwise stated on the breaker that is listed.

Now, I'm going to have to determine [After talking to electrician] if it will be cheaper to have a 700 amp service provided by the power company and installed by the electrician to get what I want [OR] get a 600 amp service with special breakers "marked 100%" in special panels.  I'm not sure which will be cheaper but I will find out and pass that information along in the forum.

Thanks for getting me to investigate this more, Prelude.

Now, back to more reading of the NEC 2015.

You never loose anything, just takes 4-5 days to reach full 5N, but if you ever decide to leave and I'm pretty sure you will not, you will get paid for 4-5 days after you stop mining also, till all your shares are out of 5N range.
