I am all for people posting their work on these forums for others to appreciate or criticize, I just feel pretty strongly it should not take an admin to MOVE YOUR HACKJOB GPU RIGS TO THE ALTCOIN FORUMS WHERE THEY BELONG!
Y'know, so that people looking to this topic for pictures and updates of BITCOIN mining rigs can find what they are looking for. I'm pretty sick of popping on here for an update or some feedback and seeing the thread hijacked for fly-by-night ETH miners trying to sell their rigs that any noob can slap together in a couple hours.

Thanks for the update! I'm going to wait for the warranty to be nearly expired before I overclock any of my s7's, but I've been playing with the idea of adding some manner of A/C cooling to my system. I've got a couple blades that run about +5 above the others in 2 different units so I'm glad to hear it's stabilized your temps overall.

Am I misunderstanding something about this paper or is everyone else?

If I am interpreting this thesis correctly it has everything to do with the manner in which an ASIC chip is laid out internally and therefore the order in which it processes data, based on purely face value it certainly has some merit, but the manner in which this person is trying to sell this technology publicly on a forum/website instead of directly to a manufacturer who MAY actually be able to interpret/test this idea on a simulation or new run of chips is highly suspicious.

Please feel free to correct my if I'm wrong and this is software/firmware implementable, though I cannot imagine how changes to processing could be implemented any other way than designing/manufacturing a new ASIC containing this tech.

Heck if the price was right, I'd gladly add in my own cooling..... so many options I don't know where I would could begin! If things are going well I want to mess around with a piezoelectric air cooler that will bolt onto the intake of an s7, anyone here bothered to dick around with piezos?

Wizard box Update 1

Hey guys, had these puppies running at 100% for a week now, I couldn't be happier! Still more work to be done to add in the 8in outside intake and hopefully add a second centrifugal fan as a failsafe and so I can bring the outside noise down.

Finished (Phase 1) 5in outside air intake + 5in inside air intake = 8in intake, 8in exhaust with ~1200cfm centrifugal fan I managed to snag used for $75 




Replaced useless laundry room window with 2x8in manifold




The door needs to be finished, same with the lid. Sound is low enough once I build the laundry room door you really won't hear it through the rest of the house.




Half occupied with my 4 s7's





Mess o' cabling 




MINING FACT: In Alberta (Pretty sure it's actually a North American standard) you *CANNOT* wire up a standard 5-15 outlet with 240v and have it pass an inspection. We wired these up with simplex 240v outlets and built these adapters which are entirely acceptable to code.


Crowded exhaust





Always make sure your 240v breakers are properly ganged!


Going to be a few weeks 'til I put any more into the rig, waiting to see what the prices on these single fan s7's do because they would be a perfect fit in this box.

Until then, good mining guys!

Haven't seen a dedicated speculation thread for it yet, there's been far more speculation as to whether any new generation of chips actually exists in a mass-producable model yet. Looking into the past I would gamble there being an "S7+" or something of the sort. It's a tremendously costly process to retool a factory and bitmain is going to keep pumping out s7 hashboards as long as possible, I'm betting on a couple more batches of the s7 single fans, and then who knows? Hopefully a 4-6 board rig with some small efficiency gains or maybe some lower sound levels.

zpool.ca is pretty reliable, I've gotten some good profitability on everything from neoscrypt to sha256, 2% fee is not bad compared to hashpower.co's 4% for regular BTC payouts.

The only thing more awesome than those two fat blocks in 5mins breaking the bad streak is sitting and waiting for the conspiracy theories and people screaming "Switch pools! Even though they're statistically identical pool x is somehow superior!" every time slush goes >20hrs without a block. Welcome to pool mining people.

Though my mine is still very much in it's infancy, I'm glad to be mining in Alberta. It's a deregulated energy market and there is companies willing to provide 250,000Kw/yr at wholesale + $.01CDN or roughly $0.024USD/kWh at present. I've known some people who use decent amounts of power for some horticultural endeavours and they have never had an issue with the power companies (I have read some horror stories from the states with power companies refusing service or demanding exorbitant rates once they find out people are mining etc.)

I will definitely be keeping the community in the loop, my contract isn't down at the $0.024 mark but is damn close, just no reason to swap companies with such a small operation at present. Personally, I hope they come bitching about power factor or something so I have a good excuse to get out of my contract and go cheaper.

I have been using PureVPN for a couple years now and I have only good things to say. Costing only $50 a year for access to a huge number of proxies I have not hesitated to keep renewing.
Assuming you're using windows their application is great to use and comes with some great features (I tested using unencrypted vs. 128bit vs 256bit and saw <10ms latency difference when I was gaming.) With 256bit encryption and the compression they use I have not seen another letter from the RIAA and happily torrent and tour the deepweb (always use Tor  ) with confidence.

Hope that's been of some help!

Indeed sir, well said.

The fact that cryptos were created, arguably, to circumvent the gigantic capitalistic nightmare that is big banking; certainly does not make them immune to those in positions of great power. I spent the last decade of my life working my fingers to the bone learning trade skills and making myself an indispensable employee to any number of companies; and now almost entirely as a result of my government pouring billions of dollars into the oil market, only guaranteeing the eventual crash, I find myself unemployed and struggling to provide for my family along with tens of thousands of others.

If cryptos hold any hope of breaking the vicious cycle of debt-creation and bubble economies, I'm all for it.

My money is on BTC being reasonably stable for the near future, can't help but have a bit of a biased attitude.

Cheers!

Always a little chilly here in Alberta, looking forward to having these babies keep the house nice and toasty year round

Alright, after 3 months of research and planning, some seed money, and an immense amount of elbow grease I can now officially call myself a Miner.


Welcome, to my Wizard Box!



Framing the box, mounting the electrical (8x240v, 2x120v, 1xCat5e)




Sub-panel run from main (60A 240v line to 125A sub) wiring finished and drywalling the interior



Soundproofing/Fire-resistant insulation



Box closed (for now, still have to finish the lid)




Woo! Mining!



Ductwork going in

Intake manifold



Exhaust manifold




Cold air intake and 8" exhaust (Still have to add the T to draw from the house cold air return directly above the 5" duct)



Miners and power supplies arrived in 3 days flat.




FULLL POOOOOWWWEEEEERRRRRR!




All assembled, sound is minimal, still have some work to tie in the exhaust to both the house heating and an external exhaust for the summer. All told by far the funnest project I've undertaken in a long time. Hoping to get another 4 miners by the end of this year, with the halving coming up I'm just waiting to see what happens to prices.

My cousin is great with these conspiracy theories, always worth a laugh.

The current hashrate of the network is 1.17EH, if we were to try and estimate the actual total cost of mining equipment on the BTC network I'm going to take s7's at current price (600USD). To gain 51% of the network would take ~126,958 s7's running full bore at a daily cost of $158,444 @ $0.04USD/kWh. I don't believe for a second any one organization would put ~$76,174,800 (not even including power supplies, power distribution, cooling, floor/rack space, assembly and monitoring/maintenance, you can basically just double that number to get an idea) worth of equipment running at that daily cost for the sole purpose of destroying BTC and ultimately rendering an $80,000,000 investment worthless and throwing all that money for power down the toilet for some imaginary war on crypto-currency.

Are people threatened by crypto-currency? Sure
Are there forces always working to destabilize the system for any number of purposes (almost always personal gain)? Sure

Do I believe any person or organization would be short-sighted enough to spend tens of millions to nuke a technology just to watch it burn? Not so much

As for taking control of the network as to make small miners a thing of the past: Well that's the beauty of crypto-currency, only if a single organization took control of manufacturing the only miners could they squeeze us out; even then how do you stop someone else from making a miner? To reduce profitability for the small miner is to reduce profitability for the medium/large miner. That's how it works. And greed ALWAYS wins. Not to mention the day a single organization takes that kind of control is that day I and the vast majority of Coinheads will wash our hands of BTC, yet again leaving the organization with vast amounts of worthless miners and coins.

Cheers, always love a good conspiracy.

It's such a grey area to define "stealing" your electricity when it's included in an agreement.
In any rental you really can't modify any wiring and certainly can't increase your supply legally, meaning the miners you could run *safely* would be relatively paltry and the consumption pretty low, not to mention the fact you are averaging your consumption with a whole building and I have a hard time really calling it theft.
All that said, doing anything of the sort without consulting the landlord is a risky venture as I'm sure some would see it as grounds for eviction (operating a business in the unit, wiring/fire concerns, etc.)

Just received my 4 batch 12 s7's, arrived in 3 days flat.
Just finished testing all 4 and I couldn't be happier. Another 18TH/s for slushpool and classic blocks 

Very sorry to hear you sent money to these people, I was disappointed to read this has shaken your faith in crypto-currencies and encourage you to push forward. NO economy, currency, or person is immune to con-artists as the weakest link in these transactions is always human beings. I have spent the last few months doing my research into BitCoin and CC's in general and my faith in the system is stronger than ever largely due to the community I see, people who will tirelessly and with great enjoyment RUN THESE SCAMMERS INTO THE GROUND. Sadly not every potential victim can be warned, and I sincerely hope your loss was a minor one.

Best of luck in your future endeavours.

I have a GTX 750ti that I have been running on Nicehash for the last two months with profitable results, If your electricity is truly $.02-.05/kWh you will make some profits by way of BTC, but based on my math your ROI will not be nearly as fast as running S7's in the current market. My *personal* advice would be to invest in used/new asic equipment if you're thinking about investing anything. As always, do your diligence on your particular situation.

Perfectly correct, I meant to say the *miners* supply will halve on an average basis, from that standpoint of course older hardware will go offline and perhaps drop the eH/s noticeably. I suppose my takeaway from this was simply that difficulty will only have to stagnate for a matter of 2-4 weeks and I will see my ROI come back. I'm just interested if anyone would agree it may be slightly riskier to be buying hardware ATM.

I'm still betting on BTC going up as a result, I feel quite strongly it's an all-around good time to be involved in cryptos, with Japan looking to legitimize BTC and Canada now regulating it as a commodity it's an upward situation all around.

By my math if you can get your power for BTC.00015/kWh you should see a reasonable ROI, I'm quite interested to see what happens when the reward halves, but I can only deduce that:

1) A number of old miners will start going offline as no longer profitable, gonna be watching to see the eH/s move before, and the 2 weeks after.

2) $/BTC will move. Flat logic would say based on supply halving, price will double over x time, with difficulty increasing and new-gen hardware it's impossible to say for sure.

3) Profit? That's down to $/kWh.

Of course the real alternative to this is that 1 happens and 2 doesn't, which means that either the newest s7's remain half as profitable and it drives up the price for the next gen, which would drive up $/BTC or crash the small mining market entirely. Personally I can't wait to get my s7's up and running and watch what happens.

As far as investing in and holding onto bitcoins, I have to say it's a pretty decent idea.
