Yea, they are clocked at 275 iirc. I can check when I get home from work. They both have 2 fans so I can run them quieter,  one of them I swapped s3+ heatsinks and it made a world of difference in temps. I can get a wattage reading as well when I get home.

Awesome I look forward to it. The only question beyond that would be are you willing to accommodate in any way for the value difference?

I am a bit lost as to the why of this.  but hear me out.

you want

solar >>> battery >> Regulator >> s-5


why not Solar >> battery >> invertor >> atx psu >> gpu rig mining eth coins

yeah I know we are talking alt coins sin sin.

but if you are going large scale right now at this moment  the eth coin idea pulls 195 watts vs   590 watts

 easier to do  .

I suggest your first tests are with an eth coin rig like I just said.  read my thread in alt coins on an eth rig


https://bitcointalk.org/index.php?topic=1429151.0

my idea has more conversion and loses in the conversion  but is ⅓ the power draw and actually earns more then an s-5 does in a day.


if you are going big scale the ability to do either or could help you earn profit over your startup cost .



I'll certainly look into this. I wont rule anything out. The only downside to running an inverter is the efficiency loss. Same thing back into a psu.

I could lose 5% stepping up to ac through the inverter, and another 5% to drop it back down to DC through the power supply. The charge controller itself is probably a good 10% alone. it adds up quick. Any regulators etc all seed power on a low scale. Running right out the gate with 12v of the panel, battery and a regulator, I'm looking at minimal loss through the regulator. Still probably a good 5%. I also need the 3x factor in terms of solar power. If I'm using a 500 watt draw 24/7 assuming I get full power 8 hours of the day I'm going to want a 1500 watt solar array minimum. This will not only power the miner during the day, but provide an additiona 1000watt charging capacity to recover the 16 hour draw.  



The best idea I have at this point is to use the power company as my battery. If I simply grid tie these units with an inverter and make up the power during the day, the solar should still run my meter backwards for what I consumed at night no?

I wanted to stay off grid with my mining but perhaps the battery's just are not pheasible right now. I know my state put the kabosh on solar efforts. The power company basically said fuck off if you made your own power. Pretty shitty world we live in.

That is sad.  As solar works well with the gird tie in. NJ and MA  are good but many states are bad.

Yeah its horrible. WE energies is among some of the worst. I read they recently shut down a Michigan plant they had, and then due to loss of profits from running that plant, decided to push that cost onto Wisconsin residents (where i live) to coop profit loss due to the Michigan site being shut down. That could be the reason for the extra hatred towards green energy programs. This is a company that is down right bitter about the fact that people creating clean energy directly affect their revenue stream. They aren't losing money by comparison.... they are making less profit. It costs them pennies on the dollar to move green (as customers are absorbing this cost all on their own) and they still won't do it.

There are two costs on my bill from them currently.

1) Service charge of $9~ a month. This covers the cost of the connection, monitoring, up-keeping and maintaining the lines, and repair.

2) The cost of the kWh you consume. For me... 0.135$ per kWh.



Now for people with grid tie solar....

WE said people who run their own solar don't contribute to the standard maintenance cost of people who pay for actual power usage. Even though they themselves state all those costs are wrapped up in the initial service charge standard customers pay.

So in addition to the standard $9 i would pay closer to $18. That's without using or sending any power at all. Now, they also put a tariff on power generation capacity. For every 1kWh capacity you generate they charge an additional $3.80 per KWh capacity from what i understand. They more or less make it completely senseless to go solar with them and i have the most efficient solar cells on the market.


This article covers the topic quite well


http://www.dailykos.com/story/2014/9/17/1328688/-Wisconsin-Electric-s-War-on-Solar-A-Case-Study


What's also funny about the claim that they lose large amounts of revenue is this:

https://www.we-energies.com/residential/acctoptions/eft.htm

Their own site... where if you want to be a customer that uses specifically or exclusively green energy that they themselves create... you must pay a higher rate

"Pay additional charge per kilowatt-hour. Because renewable energy costs more to produce than energy generated from traditional sources, the price is slightly higher."

Now that is somewhat as expected in my book (green energy costs more), but then don't make the claim that you lose money on green energy...

I have 2 s5s that have been running under clocked for 5+ months and cleaned regularly. I have owned them since may/june 2015

http://solo.ckpool.org/users/1PJ63JUfX6q8CfLUorQwMxzkkXBDXfFq7m

Interesting, so you are totaling 1.6- 1.8 ish between the two of them?

Any idea on the power consumption? I planned on undervolting

"Best efficiency with reliable starting and operation was at 150MHz,  9.4V supply (Core Voltage 0.63V) consuming 166W at the Wall giving 495GH with an efficiency of 0.335J/GH."
66  Bitcoin / Mining support / Re: Running Miner off of Deep cycle batteries - expected drain? on: April 08, 2016, 12:57:42 AM
Yeah, a good efficient buck/boost would solve a lot of problems.

Wasn't one of the later revisions of the S5 capable of running down around 10V?

I read something like that somewhere and it was said to be around 350 watts down around there i thought. Ill see if i can find it.
67  Bitcoin / Mining support / Re: Running Miner off of Deep cycle batteries - expected drain? on: April 07, 2016, 11:11:03 PM
Capacity is also a function of draw. A 600Ah battery drawing 600A probably will not last for one hour. It really depends on what the "expected load" of the battery is, what the draw was at capacity measurement.

You also need to consider regulation. Is the nominal voltage of this battery 12V? Because if it's more like 14V you're going to sorely overvolt your S5 and likely burn it up.


I do plan on running a solar charge setup inline with a few batteries. I was thinking running three to four 600 amp deep cycles on a solid buss bar in parallel. That should be enough capacity to maintain a small draw. Sidehack, I intended to use a step up/down voltage controller to regulate the output to the miner. Honestly i wanted to underclock/volt the unit to get larger efficiency so i could run two or three units. I'm shooting for a specific power maintenance level around 1kW. I could even fit a undervolted s7 if that's been done. I made my own panel out of some 21% efficiency cells. I plan to make a solar sun tracker for this panel and about 5 more.

I do realize however this is a very large expense for running two s5's  Grin   But this is more or less a proof of concept for a larger plan.

Hey guys, I'm wondering if anyone knows how a 12v Deep Cycle battery would do running a miner like an S5? Assume a 590 Watt draw just as a baseline. Is it as simple as pulling watt hours from the battery? IE an S5 running @ 12v using 590 watts is pulling roughly 50 AMP. Is it as simple to say that if the battery is 600 AMP it would provide 600/50= 12 hours? Deep cycle's don't really like to drop below 50% for long life. So 6 hours? I'm more concerned with my concept being incorrect than actual data numbers here.

I've seen plenty of naysayers shunning the use of batteries as they typically have voltage drop as load is applied and battery resistance rises. That is how automotive batteries work, however deep cycle are specifically designed to maintain voltage across a usage curve with a steep drop-off and resistance increase generally happening around the 80% drain mark.

Happy hunting

Hey guys,

Doing a new project and need a few S5's or an S7. Looking to trade my Evga GTX 980 for (3) S5's or (1) S7.

Anyone interested please message me Smiley

I'd probably also be interested in any btc deals on S5's at a good price but mostly preferring a trade for this pilot run.

Thanks,

So you bought an over 5k miner...and just left it in the box and never used it? Lol come on man come up with something more believable when your outright lying...

You people Erk the shit out of me. You don't read. You make grand assumptions. And try to make a seller look like an ass with no supporting evidence what so ever.


His time stamp is valid. And hes asking 6 btc. So no it doesn't sound like he paid 5 grand for a miner and isn't using it. It sounds like he payed around 2k for it as he's producing a profit at his asking price of 2,500. Maybe he paid 2,500. Who knows. What do we know? It doesnt fucking matter. If he proves it works to somewhere near the advertised hashrate its really none of your business now is it?
72  Economy / Computer hardware / Re: [WTS] KNC Titan 300MH - New Never Used on: March 18, 2016, 08:50:37 PM

Wow. Didn't realize what he said was a guarantee. In reading it, it doesn't sound like that's what he did at all. He made a suggestion to what it SHOULD produce. READ

75  Economy / Services / Need a programmer skilled and experienced with android on: December 21, 2015, 04:09:40 PM
Hi all,


            Looking to do a start-up. Have a pretty solid idea for an application/concept. Willing to pay a programmer $250 deposit to get started. My scope of work would think this project would finish up around $1000 total paid work. I could pay in bitcoin if needed. This project would essentially require you to be able to interface with a raspberry pi over a local wifi network and send commands via a app/GUI on a tablet which would in turn be able to output to the GPIO wirelessly. There will be graphic design involved and i'm more or less able to handle this side of things but we would need to work together somewhat.

Please PM me. Details won't be given out publicly unless extremely vague questions are asked.


Thanks!
76  Bitcoin / Mining / Re: Pics of Large Miner Hosting Center Under Construction on: December 15, 2015, 02:09:25 PM
Are you going to exclusively host the miners that will be sent by us or will you be hosting self-miners which can be bought simultaneously? (just like a typical cloud-mining service)

We don't do cloud hashing at all, and have no plans to offer cloud hash at this time, and I don't see that changing for the foreseeable future. We strictly do collocation: You send us the miner: we provide power, networking, and cooling.

What if I want to terminate the service after a year or two? Will you be sending our miners back or will you be paying it's equivalent cost price? (at a reduced rate of course)

We offer flexible monthly contracts which can be broken at any time, for instance if, you'd like to sell your hardware and upgrade to a newer model. However, if you want the miner shipped back to you, you will need to pay the shipping costs.

Can we get full access to our miners' configuration, giving full freedom for users to select their convenient pools as well as setting up their payout addresses anytime?

New customers of ours get a username and password so they can login on a portal on our website. Once they've logged in, they can see a page which displays their miners' temperatures and hashrates. Each miner is represented by a rectangular tile. If you click on a tile, an authentication dialog pops up (root/root) just as if the miner was on your LAN. Once you've filled out the dialog, you can set pools and have access to all the options within the miner you normally would have access to.

Will you be live streaming our miners in order to verify if they are maintained properly? (For instance, Genesis Mining is having a 24/7 live stream of their miners here => www.lifeinsideabitcoinmine.com

I'm currently living at the datacenter, and I'd like a little privacy, haha. This is a good idea though.

In the meantime, I'm gonna watch this thread and will eventually contact you after the construction gets completed and if everything goes right. Smiley

Construction already finished on the facility that pictures are posted for early in this thread. We leased space at that data center from the data center owner, however, we were forced to move about 50 miles away to Quincy, WA this summer when the owner was not able meet the cooling demands that miners require in the Washington summer.

The Quincy site is currently fully operational and we are offering the rate of $55/kw/mo (7.5 cents/kwh) to both small and large customers.

A few quotes from their ToS


"Our maximum liability to you under the contract shall be twice the value of the goods that you ordered."

" If payment is not received within the time that is customary for the used manner"


Or the fact that they haven't tweeted in a year

Those kinds of offers are almost always going to end up being a scam unfortunately.

I personally would not trust any miner reselling website to buy a miner from (unless I was also using a forum based escrow), and I am not even sure that there is a single reputable website that resells miners.

He's a scam. He deleted one of my posts accusing him of being a scammer and locked the thread.

I wanted to add though there is a bitcoin hardware reselling website that can be trusted. User here known as HolyScott
