I consider underclocking / undervolting my antminers. This should enable two antminers to run on one PSU. Problem is that my PSUs only have two PCI-E connectors.
May I use some of the other connectors? Can I cut off the end of the CPU connector and connect three of the yellow cables and three of the black cables to the corresponding slots on the miners?
as per S3 message board, you can connect molex (4 pin connectors) through 4 pin to 6 pin adapters to PCIe slots. I have never done this so far, but plan to try with S3 9 I also have CX500M which have only 2 PCIe connectors. S1 undervolted should be just 200W, right? I have 3 running at 560 watts total with 420gh total so 180 to 200 with 140gh is a good estimate. note I use a evga 1300 watt gold psu. on sale here http://www.newegg.com/Product/Product.aspx?Item=N82E16817438011&cm_re=evga_1300-_-17-438-011-_-Product |

I have 17 gh pointed at this. I finally seem to have achieved a working connection. I also spoke to the op on the support free node. A few questions here is my settings page  and here is my mining page. We talked on free node today I assume that I have done this correctly based on our prior talk. please confirm. and you also are a part of oz coin correct?  |

Thank you this is much appreciated . If I get lucky I will tip you. |

I finally got up and running on solopool.net
I am doing 17gh in usb fury sticks.
I was told it is a branch of oz coin pool.
Any info on it would be helpful.
Seems to be okay. I am looking for help to set up a .bat file on it
I run bfgminer 3.9.9 a special build for the 2x fury sticks.
I don't want to type in my btc addess each time I run it.
So if some one can point me to the right links please do so.

Sadly 1/2 of that went over my head to be honest, but I will read up on it.
Would there be a way to have software implement a query to make sure the miner will submit a winning solve (like a test solve) every X number of shares. I guess that would require a protocol change since the pool would have to issue the challenge work.
ASICs do not always test every nonce from 1 - 2^32. There's many reasons this may happen such as 1) Many will slice that range into pieces based on the # of chips on the board, giving each one a slice. If a chip is damaged, that range isn't checked. Hardware errors. 2) It may be setup to have modules, with each module getting a range, but some units only have 1 or 2 while others have 8. Instead of splitting the ranges up evenly between available modules, it gives them their static range and ignores the others. 3) It may immediately feed in new work once a solution is found for a nonce range, even though multiple solutions can exist in the full range. Additionally, modern mining protocols have the miner use a local counter inserted into the coinbase in order to generate work (this is why stratum and GBT are immensely more efficient than getwork, they can make their own work locally). That counter will be in a different state for every single miner. If a call were added which forced miners to have that counter in a specific state, you've just clued in a block withholder that the work it received is a test for withholding, so they won't. So at this point we are left with no workaround or method of detection for withholding attacks short of statistical outlayers? Forced solo mining on all pools for 1 hour a day . We all bear the burden for that hour and really large defective miners could be found out. IE a 2ph mining setup that never makes a block during forced solo mining it would certainly be found easy enough. Also adds the element of luck for every miner on the pools. The cost is nothing for a pool operator for the 1 hour a day. As pools keep track of the block makers any way. This also make test mining and tweaking a large amount of miners/software such as the 2ph miner less desirable . Since it may show it is defective during that 1 hour of solo mining. So while this is not a perfect fix it is low cost to do. Makes the network far more diverse. Frankly where is the down side to it? |

Do you think that "bad hardware / software" exists and that could make the pool vulnerable?
Like I said, all mining pools are vulnerable to block withholding attacks. All pools. Whether bad software is still out there, I don't know. But as we have seen, it can happen. Bad hardware is very unlikely. All the ASICs I heard of so far simply look for anything from diff 1 and up. Doing something else would require more logic on the chip. Okay, I concur all pools are vulnerable to block withholding attacks (currently) .. and established bad software exists, and we can debate hardware concerns pointlessly as a "consumer union" report would have to test different hardware with testcases. So, given that vulnerabilities exist, do you think it is possible and worth protecting against known vulnerabilities? Is there a statistical test to say that a miner or group of miners are behaving unusually ... I would think there is. yes there are tests, but all involve groups of about 100th to 200th of hash. In bitminter : group 1 total of 200th koi group 2 fefox kdecastator tyson76 rbatista204 MRoj r0ger jay83434 spiccioli amahastpl xportz finnfiu jzarcaro total of 200th make 6 groups of 200th each group of 200th should make around 9 block per month that drops as time moves on. after 1 month you could see if there is a terrible group. the problem is the groups at the bottom will have many little guys. Next test method put koi on the side. since he does so well. pick 5 top miners 95 bottom miners pick 5 more top miners 95 bottom miners. say 5 piles of 200 th groups with a few big guys and a lot of small guys. look for 1 month see what happens. All of the above is needle in a haystack and not the best way to sift out really bad miners. Also does any one care if a 6gh miner sucks no does anyone care if a 60th miner sucks yes. Well I like doc h I have 3 s-1's pointed here and will keep that up. I have my hosted miner at btcguild. And more firepower in gridseeds pointed at wemineltc.com I feel I may end up being a solo ltc miner since I can point enough gear solo to get blocks. oh I now joined solopool.net pointed 17gh there. rather do it here solo . pointed at solopool.net  pointed at bitminter  |

Came across this site was wanting to solo mine my s1 there if I can can ever get it running(long story)they claim to give the founder of a block the full 25 minus transaction fees for pool as well they are merged mining namecoin and keeping any name coin found for keeping pool up and running
If you are talking about the solo pool set up by Ozcoin, They are legit. He's not, he's talking about this: http://bitsolo.net/Oh, i thought he meant solopool.net. This is why people need to be clear about what they are asking. We can't read minds. Solo mining is really nothing more then using your machine as a lottery ticket unless you have a significant portion of the network hashrate. wrong so very wrong but not completely wrong.. a lottery ticket pays terrible odds. 3 digit number should pay 1000 to 1 most lottery 3 digit numbers pay at 500 to 1. if you are using any gear at 1.6 watts per gh it is like getting 1060 to 1 on a 3 digit number . pretty accurate estimate for today. the problem is you use 10 gh or 30 gh and it is like only having 1 to 3 numbers out of the 1000 numbers so most likely you lose. most of us can't buy enough tickets and pool with many other ticket holders and since the overall payout is 1200 to 1 on a 1000 to one shot we all profit. Any one that says playing 10gh in solo mining is like playing a lottery ticket is missing the fact that the solo mining pays at a much higher rate then a lottery ticket. A truly huge fact that is why a good clean easy to use solo pool should be part of every miners pools. Especially a smaller miner. I mine 10gh at solopool.net . I never think it will hit a block. but It costs under 16 watts to do this. which means every day for 6 cents of power I can hit blocks. Show me where for 6 cents getting a 15000 prize (600 x 25 = 15000) is possible. todays odds of 1 block found for me = about 67,000 to one. I spent 6 cents for that chance since 67,000 x 6 cents = about 4000 usd . my payoff should be only 4k if I hit the block my payoff would be around 15000 usd. so 4000 usd vs 15000 usd seems simple solo mine is better. well you have to hit the block for the benefit of the higher payoff. I also was a little bit misleading. Since I said I spent 6 cents to have the chance at the blocks true, but if I pool mined the 10gh I would have collected about 22 cents so my real money spent is : 22 cents a day for a shot at 15000 usd. that comes to a 68,181 to one payoff for something that should pay about 67,000 No lottery ticket overpays like that. |

you need to know bitmaintech decided to hold the gear and mine for a week before they sell it to us.
hash spiked 27ph it is not all bitmaintech.
So AM held the gear a week and decided to mine with it.
BFL may be mining the monarchs
The sp30 maybe mining right now.
that gives us the 27ph spike. I am most likely not going to hang in with the current BTC diff spike.
I did some math. I am at 1.6th of paid for btc gear. It has just about done roi. I spend 800 watts in house for the 600gh and I have a hosted 1th miner that costs 180 usd a month.
A realistic power ability for me is 2k-watts summer 4k watts winter. I need 3 s-3's now and that will max my power for in house mining for the next 75 days.
I will go from 1.6th to 3.1th spend 3btc to get the gear.
Or I can increase my gridseed blades for 6 doing 32mh and 510 watts
to 9 doing 48mh and 775 watts. cost about 3btc.
It looks like I need to put money into gridseed blades ..
As I can expand and keep power under control way better then any btc gear available.
My network share of btc is a joke 1,600gh/128,448,261gh or .00000124563 and with 4 k- watts max I have the k-watt power to 3x my network share.
My network share of ltc is 32mh/338,664mh or .0000944889 and with 4k-watts max I have the k-watt power to 8x my network share.
I have some tough choices do I expand my gridseed blades in house?
Do I expand my btc mining gear with s-3's?
Do I expand my hosted gear?
The delays from bitmaintech and from AM with the s-3 and the RK-BOX have pushed me towards gridseed blades.
I am waiting for one to come from china once I determine it is could I will most likely get more.

I put none. Since you put at s-2 prices. If it was at the best s-1 price I would buy 10 or more.
Note the best s-1 price I paid was 173 usd an s-1 which was under 1 dollar a gh.
The best s-2 price I have seen is about 1.40 usd a gh. that would be a no go price for me.

and to chime in I stuck with crazy guy's build 6 units run flawlessly on the custom 4.3.3
I get 194-196 gh. they run at 38-41c in a room temp of 84 f.
side mount is better then fans up

If you check out Stunnas recent post you will see has asked us all to suggest an opinion on the best way to change the system. You should read that post and add to the discussion so Stunna knows your opinion. Too much spam, multiple accounts abusers are the issues up for discussion and how to fix the problem is what matters at this point.
"Quote from: Stunna on June 20, 2014, 08:25:40 PM

I firmly believe it is impossible to make more than 100 really solid posts in a week. 9/10 people who are breaking that limit are just posting worthless contributions as rapidly as they possibly can.
Preferably I'd like to just pay people a fair price based on their rank which would cut down on forum spam tremendously this could upset a lot of participants though. If anyone has some suggestions on how pricing should work for that scheme I'm all ears."
Please stop spreading FUD. Stunna only asked for opinions, and he never said what you quoted. Reminder: 2440 Yes he did: Drastic changes here as well. Seems to me like the era of people having a decent income just for posting in a forum is over. Time to move to something else maybe. Posting is more like a hobby to me, the fact that I can earn some pennies by doing what I like sounded good. But good things don't last forever.  I don't think sig campaigns are going to die soon though, the frequent posters will certainly do though. hehe Actually it is good, now it will stop spamming in whole forum. I firmly believe it is impossible to make more than 100 really solid posts in a week. 9/10 people who are breaking that limit are just posting worthless contributions as rapidly as they possibly can.

If anyone has some suggestions on how pricing should work for that scheme I'm all ears. Oh. Lol, fail on my part. Quite disappointing, I think it's perfectly possible to make more than 100 solid posts in a week. 10 minutes to make a solid post means 1000 minute to make 100 solid posts. that is 16.5 hours in a week 2.4 hours a day. Many people have the time to do 5 hours a day on this site . which would mean they could do 200 good posts in a week. If you bother to read most every thing posted in the last hour. I am sure many of us good give a good answer to 20 posts every day. I still fell it is stunna's money and */-he get sot doe the rules |

buy some gridseed blades miners from zoomhash. they take up 80 to 90 watts. they can run with a pcie to dc plug adapter from an atx psu I have 5 going on 6. they run about 700 usd. you will hash at 5 or 5.2 mh here are five running for me. note each blade has two board so 5 blades = 10 workers. will they roi  ? i do not know if they will/. www.zoomhash.com you can use a cc or paypal so you will get the gear delivered.  actual blades running  |

I have 10 S1 miners and I have 6 Thermaltake 1000w PSU's - I thought that I could run 2 of the miners on a single 1000w Thermaltake, but I can't. I have an 850w Corsair and I can run 2 S1 miners. None of my miners are overclocked. Maybe by under-volting my miners, I can run 2 on one of the Thermaltake PSU's. Will the drop in hashing be more than made up for in electricity savings by using 1 PSU instead of 2? Does anybody have any other suggestions about why I can't run 2 miners on a Thermaltake, but can on a Corsair? I don't want to spend any more money on buying more Corsairs' Has anyone had this problem? How did you fix it?
I had your issue with fractal 1000 watt psu's. you could buy this psu it runs 3 and is on sale 195 usd http://www.newegg.com/Product/Product.aspx?Item=N82E16817438011&cm_re=evga_1300-_-17-438-011-_-Product35 usd rebate form http://images10.newegg.com/uploadfilesfornewegg/rebate/SH/EVGA17-438-011Jun17Jun2314yh62us.pdfyou can do the pencil mod and clock your gear to 300 freq hashes at 140-150gh pull 180 -200 watts. |

Problem is that this was not particularly bad luck. You can't call it consistent either, because they mined for a very short time.
Complaints started when their mining was at a CDF of about 70% which is just silly.
Even at 95% CDF you may think this is really rare, but it's not. If you crashed your car 1 out of 20 times you drove, would you still say that's so rare you would never expect it to happen?
I'd suggest we finally do the hardfork on bitcoin that has been suggested long ago, which would make block withholding impossible.
Concerns were raised because of: - a history of other pools being abused - the very large size of the user, with no pedigree of success on other pools - the risk of others using the pass through to veil their exploitation of the pool - the opaque means that flound makes a profit with this venture - below expected returns from multipool The combination of those items make it very likely that users were being exploited by multipool. It's called Bayesian analysis. And at 70%, with the additional data it was perfectly rational to start asking questions. With PPLNS your incentives are not aligned with your users. You lose nothing when the pool is being exploited. You collect your cut regardless and just distribute the rewards unfairly. That means users like me have to be watching carefully. Given his response, I think it is very likely that Flound knows, or at least suspects that some of his users are exploiting the pool. I have to wonder how far you would have allowed things to progress. A hard fork of bitcoin is out of the question, for the same reasons that countries almost never rewrite their constitutions. Too many competing interests would attempt to force their interests into the hard fork, and consensus would be impossible to reach. We are already past the point where a super majority favorable to public pools could even be formed. A revision to stratum is possible, and I'm quite surprised it isn't being actively driven by pool operators. well the problem for a midrange player like me 10k in gear 500 usd power bill is pretty simple. I can stay in BTC pools that are not addressing the bad luck, bad gear, bad software issue. Knowing that solo mining is not practical in the btc world for me. So I could slide over to alt coins with gear that I know works and push comes to shove i could solo mine. any coin that grid seed blades work on. I have 4k plus in grid seed gear burning under 600 watts. I have 1k gear in house for btc gear burning 800 watts. I have a 1th dragon miner hosted in china costing 180 usd a month to host. I have more then 10btc to hold or invest. So I have various ways to go. I really want to continue to mine BTC but LTC + alt coins have grown for me while I have shrunk btc due to the pool issue I see. Frankly pool ops need to get together on this one way or the other or more of us may drift into alt coins since we won't be so small a fish so to speak. MY skill set is not coding so if some says stratum revision works lets do it. I know quite a bit about quite a lot of things in life and i can say doing nothing at all is not the best idea for pool ops. |

Is that a bong in that picture, Philip?
Nah I am old school never liked pipes or bongs.. just joints back in the days of purple haze and shit say 1972-1991 my stoner years but I quit weed in 1991 I quit tobacco in 1996. all other fun drugs were stopped in the late 80's . Still drink a bit. Just too old for the other stuff. LOL |

@wpgdeezReally? if Spondoolies sold at those prices, We'll try to reach them. (I not, WE YES!  IMHO that price is unrealistic to 6TH/s I have read about the BM1382 and I think the comment that best describes BITMAIN company is this: Still waiting for resolution on damaged & underperfoming S2 miners.
Still waiting to hear more about upgrade blades and what to do with old blades.
shall we brush all that under the rug and just focus on more sales asap??
Spondoolies have proven to be a reliable and trusty company. I don't know their big errors (I don't know if it exist). They use OpenSource products and you can reconfigure all the software easyly. please I never knocked your gear or the s2 from ant miner.. fact of the matter is sept delivery is too far from now. but both ant miner and asic miner have already held up the s-3 and rk-box for 1 week as of today. plain and simple all three companies are playing games to max their profit. BTW all of you should do exactly that. Me I will mine ltc with my gridseed blades for now and wait for something worth while in the world of btc. |

What may seem silly to you, is not to me. But then our rewards and costs are not exactly aligned with you as the operator of the pool. The cost of free riding is far less to you than to the miners. For some, it is the difference between profit and loss.
You and ooc are looking at this from the perspective that each pool is a 'fair deck' whereas I firmly believe there are miners that do not work.
That difference likely makes me shoot someone who jumps the wall to my house before he robs me and before he pulls a knife and kills me. OOC would state "there is still a 1 in 1000 chance that this person is in your home by chance and picked up your belongings by chance and that the blood coming from the stab wound was not from his knife". I overreact, he under reacts. BTCGuild is a GREAT example of this. Constantly I (and others) were told we were being stupid and it was bad luck and this happens "all the time" (although all the time was like 3 years ago wasn't it?). What happened? Who was correct?
Do I think multipool was a bad actor? Not likely. Do I think something could be wrong with his code or his users equipment? Possibly. Do I get more suspicious by his lashing out at people from the very beginning? Yes. His arrogant denials? Yes. His unwillness to prove us wrong by hashing until his luck normalized so he can satisfy his ego to call me an idiot? Very suspicious.
Now you know where we stand and our tolerance for risk and that the tolerance level is based the fact there is some unknown amount of bad machines out there. It is your pool, you are free to make the rules.
well ddos a fact no one argues. bad luck miners seem to exist. I am a small miner in fact I have more mining at ltc then I do at btc. My ltc gear makes blocks not a lot but it does make blocks. I have not made a btc block in a year as I have not grown like the network did. Back in 2012 I earned a coin a day and made a block about 1 time a month. All gpu based. My last block was with an asic miner be usb stick in very early sept 2013. my btc hash is 1.6th or a block every 14 months. my ltc hash is 26mh or a block every 23 days. Right now I am more inclined to stick with my gridseed blades and mine ltc why ? I know they make blocks. For now I can keep up with the diff rate. You can buy 10 gridseed blades for 5000 usd and burn only 800-850 watts hash at 52mh and make a block every 12 days. You need to buy 56 s-2's or about 84000 usd and burn 56000 watts hash at 56th and make a block every 12 days. I have the money to buy the gridseed and run them so that I can see blocks made. I am doing it right now. I am not going to be able to do this with BTC so I need a pool. I would like to know it is a good pool. I would like to know certain gear works well. Say an s-1 or an s-2 or an s-3. Or another way If I have to solo mine LTC I already know my gridseeds make blocks. |

saved for updates.
please ask him what he charges for wholesale gridseed blades. So far I am impressed with the gridseed blades. I just ordered my sixth one today. I would consider getting up to 4 more. |

Having some issues with the Silverfish, either chained or not chained they seem to only stay at full speed for a very short period of time, then slow down over 4-6 hours, and then speed up again, and repeat.
Two things I can think of. What is temperature like? It seems to be more susceptible to heat with open air then the A2's with closed case. With 6 in a row without extra cooling this most likely could be it. Looking at setup of 6 pulling air from against wall so close together and no extra fan's or cooling I think this is best bet. The firmware would be second thing to look at. What does your second tab in the blades go to, does the performance (M) go to 14 and level there? Old firmware seems to not level there. Edit i should add this just so it's out there in-case anyone else needs this I didn't mention earlier as your mining experience is difficulty level. But the difficulty level on pool needs to be set high enough to optimize the asic miner. If difficulty is to low it can cause high variance and low hash rates. Temps are less than 55 , so not a problem. The are pulling 65f air right from an over head AC you cannot see in the pic. Firmware is the latest, and is at '14' Diff is set correct at the pool level. I now have 2/6 blades showing a dead blade out of the 2, and they still do not remain hashing stable for more than a few hours. So bob is this still a work in progress for scrypt gear… I am running gridseed blades and I have been happy with them. these looked a little better but now i wonder. |
