Dumb question, perhaps...but curious whether to try to bump the freq on my one Batch 12 S7 to maybe 725. The changes I made to the rack have both the units down by 10+C...and this one's running a consistent <=60C on all three boards. PSUs are 2KW split boxes (1KW ea) and up to it, I think.
Any educated guesses on what would happen? Worth the effort/risk? This box is off warranty.
Sure eventually there is a freq that is too high and the gear has more hw's so the freq setting makes you lose money. so 700 = .0001 hw + temps are low bump to 706 = .0010 hw temps go from 55 to 58 bump to 712 = .0025 hw temps go from 58 to 61 bump to 718 = .0050 hw temps go from 61 to 64 bump to 725 = .0250 hw hemps go from 64 to 67 too high drop to 718 this is a typical result. your top end will be 712, 718, 725, 731,737 just move your freq 6 at a time

It's probably true, look at the huge jump in difficulty recently. We're looking at 8% next.
I'm beginning to believe there is a next gen rig out now for the same reason. If they do in fact have a next gen rig in operation now, do not expect it to be available to the masses until AFTER the halving. It's only logical they will take advantage of the gains to be made between now and the halving with a next gen rig. I would if I were in their shoes. looks to me they emptied the racks they have of s-7 and put in new gear. so 100ph using 25-30 megawatts is now 180ph using the same 25-30 megawatts . They will do this til the ½ ing then sell the s-9 to the rest of us. by the way I now have 186 s-7 coupons that expires in 2 days. so if yoy want 5 or 1 or 2 or 3 or 4 let me know.

What a crap article, so much typos. Anyways, i guess this just prove competing with China's cheap labor, parts and manufacture is a hard thing to do.
power costs killed them more then anything else they never could self mine to off set costs

even the best asic now will mine peanuts for you let alone computer, you need a big farm of asic not even a single asic, but it's true that new asic are coming, i guess those new asic will be made obsolete quickly because of the halving
yeah right today an s-7 with a psu would be about 650 usd burns 1325 watts at the wall and makes about 2.75 usd a day after power if your power is 10 cents a kwatt. or 82.50 a month if you know how to build a cheap rig mobo = 75 usd windows 7 = 40 usd cpu = 45 usd psu = 90 usd ram = 40 usd dvd player = 20 ssd = 60 total = 410 2 r9 380's = 390 price = 800 power used = 400 watts you get 40 mh for the 400 watts that is about 135 usd - 30 power at ten cents so net is 105 a month but you have a real computer with good video cards. you use 400 watts not 1325 watts and you mine Eth coin not btc...... so for today right now it is an easy choice plus

And to anyone that wants a 100 dollar coupon I still have more the 69 of them left.
Hi Phil, sent you a PM for a coupon. Cheers. [/quote] I need your bitmaintech id to send it to you

To clarify why Kano makes us wait to hit a block for payments to clear. We had more then 250 miners so a payment has more then 250 entires and takes about 45,000 bytes.
Kano pays a .002 fee to send the block payment. If you want real fast confirm on a 45,000 byte transaction you need .01 not .002.
So we save at least .008 in fees on every payment made.
To top it off almost every fee he pays .002 x 850 = 1.7 coins ends up in the fees of the blocks we hit.
So we saved at least 6.8 coins. And we added about 1.7 back to our blocks. That is the up side. A gain of 8.5 btc for the pool. The down side is payments slow up just a bit.
I did a few estimates the one of 6.8 btc in fees not spent and 1.7 btc in fees added back is the conservative estimate.
And we just hit a block so payments will confirm now.

So if I flip burgers and buy BTC, I'm indirectly mining BTC? (Minimum wage paycheck) => (BTC), voila? Some twisted thinking, but K.
The vast majority of altcoins don't even have altcoin X / USD pairs. You are forced through BTC first to cash them out. It's not that big of a step, or so twisted. By your logic, everyone buying BTC is "indirectly mining" BTC. By the same logic, miners selling their mined BTC are "indirectly mining" USD. Because they wouldn't mine BTC if they couldn't sell it for USD. So ya, twisted. TL;DR: There is no such thing as free electricity. Unless by "free," you mean "steal without getting caught."
Well someone is mining with those GPUs and it ain't the Chinese... Well ya, people like you, who think that stolen = free. Mind you, I have nothing against theft, just don't want you to misunderstand what it is that you are doing. Electricity is free to you, but your mom, your landlord, or the people around you have to pay for it. So mining on "free" electricity is no different than starting a toilet paper business, because you can get free toilet paper from your school's toilets. P.S. Don't. I can explain to you cases that 80 and 90 % discounts are perfectly legal. My friend rented on floor of an office building then sublet it to a printing business he kept 2 small rooms about 10 to 15 % of the floor. The sublet has the printing guy paying 80% of the 13 cent a kwatt power bill. My friend has had the lease for 15 to 16 years. He usually got a 1000 a month power bill that was paid 800 printer 200 him. He got screwed on the deal for 11 years as the real power split should have been 910 to 90 the printer used more gear and more ac in the summer. Since my friend was getting the rent at 80% which was correct he never bother to say the power should be 90-10. bitcoin came along now the bill was 1150 that is now paid 920 - 230. So he is not stealing but paying 30 bucks for 150 worth of power. So we first mined s-1's then mined s-3's now mine s-7's perfectly legal and not stealing.

So, Spondoolies lost because they decided to not openly screw over customers (from both a design/feature and service standpoint) in as many ways as possible and still retain customers? Sounds about right.
yeah no matter how you phrase the language Sp-Tech mining it sp20 at 3-5 cent power would have given them a real cushion in the game. They were not able or willing to do this which is why they lost out more then any other reason. If I build my gear in Howell NJ and drive it to my 40 acre solar farm in New Egypt, NJ a short 7 miles from my house I have a huge edge over other builders. (note this farm is not yet built or is even soon to be built it is merely possible to be built) If I stay stealth until my farm's capacity is maxed out> I can then sell my gear at the lowest price on the market. Basically this is what bitmaintech does. To further their edge they do not sell chips so that a guy like sidehack can build a miner that is versatile. Say .19 to .31 watts a gh So far bitmaintech has pulled this off and made $$$ . Should be interesting to see what the ½ ing does to this.

Apparently MiningSweden has bought S9s the launch should be just around the corner
proof ? Only proof right now is on the Mining Sweden website. They did S7 hashpower preorders a month or two before the S7 got released. So if you go by that, then it could mean the Antminer S9 could be on sale within a month or two. Difference is this time Bitmain are keeping quiet on it so whether Mining Sweden have just left the cat out the bag bigtime, who knows for sure. what cat these are simply preorders on cloud mining. 100 share of 20gh = 2000gh or 2th of a s-9 that does not pay until they come. 2000gh for a year earns about 705 back without a 1/2ing they want 598 for the 2000gh good luck with buying that.

So you wouldn't consider the slick rackmountability, total adjustability, integrated server PSUs, spiffy UI and everything else Spondoolies did (and charged a premium for, then sold truckloads of) that Bitmain doesn't to be "frills"? Please, define "frills".
I would not consider it successful, no. The buyer has to pay for those frills, and unfortunately Spondoolies wasn't able to recoup those costs and still be able to sell units. As scyth3 suggested, no frills won over frills. Bitmaintech won over sp-tech because of power cost not gear cost. If I build and mine at 2 to 5 cent power cost and you build and mine at 9 cent power cost you will be ground down over time and lose. But wtf do,I know I know this at 1 cent power an s-3 still turns a profit. Sp-tech was never able to self mine the way bitmaintech did. In the long run they died off because of this more then any other reason. I could make Avalon win over bitmaintech if I supply them with all the free power they want. It is obvious bitmaintech has a huge source of cheap power for self mining which allows them to sell gear cheaper then anyone. The current price of 433 for an s-7 after coupon is a fine example of how they leverage the low cost power to rule the world of Asian asic mining. Avalon is content to be a distant second since it works for them. I would not mind Avalon picking up their game a bit. But I rather see some chips sales more then any other thing.

i cant find this listed anywhere, and i havent had one so i dont know.
i do know that they use an external controller, a rpi.
my question is if i compile cgminer, will they run off a laptop usb?
You need the little dongle also to convert from I2C (or SPI, I can't remember which they use), to Serial - but a PC can certainly communicate with them then. Avalon supplies tools to diagnose the boards that run on the PC, and I used them to check cores before. Now, whether or not they latest driver code is part of the CGMiner tree, I don't know - but if you don't have an RPi, the easiest thing to do is probably just to compile it and see, if I remember correctly the dongle just enumerates like a normal USB serial port on Windows, so it's probably the same on Linux. Hope that helps... yes that helps a lot. thanks. the kit https://bitcointalk.org/index.php?topic=1318003.msg13598167#msg13598167you need the kit as the software on the rasp pi interacts with a daughter board in the miner

I disconnected everything else and used 1 separate PSU .. so those 154W was only connected to the gpu
(different psu for mainboard and cpu)
You have a 6 380itx rig right now right ? What power supply are you using ? Whats the draw fully loaded with six cards and a hard algo.. Whats hard ? quark or whatever is hardest..lol You might find this post from earlier today interesting: https://bitcointalk.org/index.php?topic=1461408.msg14768588#msg14768588I only use 5 GPU's in my rigs. I find the mobos cheaper and easily available, and everything generally is simpler with 5gpus. Also less strain. I use overpowered PSU's .. just to keep the load fairly low for longevity. So on a 5 x 380 rig i use 1300+650 On the 5 x 390 is use 2 x 1300 (i like using sep psu for mobo, disk, cpu, fans and system) Can you under volt the 380? The default voltage is usually too high. So you can save some energy and use just one PSU. No .... not without any form of modding i think. Thats a good selling point for NVIDIAs btw. They can be undervolted, underclocked, and underwhatered ... I would love to be able to do that with amds... With 7990/280x or some R9 390, you can change the Core voltage with MSI afterburner or the Sapphire Trixx. the r9 380 can undervolt if you get the correct one

just got back from brooklyn navy yard we had a DIY audio speaker build contest. So I was busy since 8am till now. block count for sat https://blockchain.info/blocks/1462590928160410734 (Main Chain) 2016-05-07 23:53:18 410585 (Main Chain) 2016-05-07 00:01:04 that is 150 vs 144 or +6 and early sunday https://blockchain.info/blocks/1462677328160410749 (Main Chain) 2016-05-08 03:17:16 410735 (Main Chain) 2016-05-08 00:03:46 15 blocks in the time it takes 20 or -5 so for the weekend so far we are at a +1 pace. granted it is too soon for the winding down to be official . Fingers crossed that we back off more and have a gentle price rise . Maybe a +3 % and a price of 480 at the end of this period.

the fans sensor wire could be bad. when the gear fires up for the 1 or 2 minutes do you get a fan rpm number?
Also what batch number is the fan?

Like if you have an old s3 thats over clocked with some burnt out chips you give a power source that won't shut off like it should or like this rental I just cancel because it had half rejects... You can always just find a trusted miner and rent old school. Miners usually love getting advance coin. A few days or a week up front is a bill they can pay early or a rig they can buy early. The should be a thread for that... Don't expect compensation like MRR, just pick a stable miner. Prices are way to high on all renting on sites right now, we are going to have to stop paying unreasonable prices or it will never change. NH eats orders up and drops them at will. They all have choppy connections, and %95-150 of diff estimate rental prices. I'm not sure of the point. People renting to boost Kano has just killed any profitability in the renting market.
Yeah I backed off renting. Will just do core mining real gear with32th

Damn this looks dope, up and running now yea?
yeah we are up to 6 + ½ avalon 6s' about 22th. slowly adding more hash We will add 2 more avalon 6's I have been talking with some bitmaintech guys about a possible s-7 or 2 as kind of a joint venture. They front us 2 s-7's we split the coins. So if we add the 2 avalon6's and the 2 s-7's our current capacity will be maxed. At just about 37th which is not much anymore. I am more of the mining end and of course buysolar is the solar end .
