any ideas on modding the fans so its more quiet?
if you have a molex->fan adapter that provides either 5V or 7V try that. at 7V the fan is a reasonable volume and can handle stock speeds as long as the temperatures stay <65C. if its a colder environment, 5V is living-room volume but needs cold air or has to be set a bit below stock speed |

In other words: which is the better miner, when- hashing on same speed (1,1-1,3 TH/s)
- powering 2 units by one of these PSUs
- having the same prices per unit to me
- regarding the noise
Appreciate your help. ... - can be undervolted to 10-11V to achieve even better efficiency - in the range of 900/360 (SP20 doesnt really get any better than 900/420). This requires uncommon 12-10V voltage regulators though and generally there's 5%+ losses in doing so What was the lowest voltage someone has verified the chips start at? I had a look at getting a variable PSU in but they were stupidly expensive. someone tinkered with it and found it really wasnt stable or capable of the advertised 9V = ~0.25w/gh, and that the lowest settings were somewhere around 10.5V or ~0.4w/gh. I almost want to say it was phillipma, but am not 100% i think its in one of the S5 review unit threads |

That is what is known as "letting the market set the price".
last auction that did that, i scored an pair of S2 for 0.2BTC/ea + shipping antminer, not a series 2 - sorry i didnt clarify that. interested to see where this auction goes. if the hologram was in a bit better shape id be bidding aggressively  |

Mines are running at 250W, cable just a bit warn...
what awg and room themp? thx poor quality 16awg can handle around 250-270W. high quality 16awg can handle about 300-320W. (18awg is only good for about 150W). having a bit of airdlow over your wires allows them to carry 20-30W more before getting as warm |

- powering 2 units by one of these PSUs
- having the same prices per unit to me
- regarding the noise
Appreciate your help. - at about 1.16TH, the units are about equal for power consumption (~580W) - for 2 units on a 1300W PSU, either would work fine, as you would be running at about 2.35-2.4TH/1.2kW with either system - for the same price, take the SP20 - noise-wise, you can turn the SP20 down to 10% or less fan speed within its OS. on the S5, you need to physically modify it to provide lower voltage to the fan (ie: use molex 7V adapter instead of PWM) the SP20 is a far better OS by a long shot. If you want a device thats about 1150-1200GH/600W its the winner. where the SP20 excels: - if an altcoin comes out or BTC price sharply rises, you can push the SP20 to 1.65TH/1.2kW if extra hashrate is worth the lost efficiency - fan control and custom power settings where the S5 excels: - overclocking to 1300GH/660W (whereas the SP20 is about 1300GH/700W) or as high as 1400/720 (Sp20 is 1400/800) - can be undervolted to 10-11V to achieve even better efficiency - in the range of 900/360 (SP20 doesnt really get any better than 900/420). This requires uncommon 12-10V voltage regulators though and generally there's 5%+ losses in doing so Bitmain's next step is to use the S5 chips in a longer chain to achieve something like 1.5TH/500W. I don't think spondoolies is capable of improving the current rockerbox chip any further than 0.46w/GH unless they also go with a chain design or create a chip that's better suited to lower voltage |

my early guess?
-4.25%
I think it will swing down int he next few days as high difficulty pushes more miners out again

I get jealous some times knowing I can't buy the larger rigs. Even over electricity I'm more concerned about noise. Not a temporary fan change or a duct tape job, I do really need it quiet.
IMO an SP20 can run at up to 1450GH with very reasonable noise at fan speed of <30%, a single wall between you and it is generally sufficeinet. if you want to be comfortable in the same room though, it needs to be <10% (or <1200GH) but you'll never be able to get away with an SP3x unit - the power supplies are outrageously loud at anything over 70% load |

I tried the other way around, but I found out it would prevent me doing business in the long run..  I understand and you are not breaking any rules against doing so but at least you could of registered another nickname. Some might not be too happy that you are just raising the prices of these miners for personal gain. Why should I try to hide the fact that I am ready to buy and sell? There is nothing to be ashamed for. The only thing that matters is that, for a specific trade, both traders profit from it. No both traders with you actually lose profit because you are the middle men pretty much. Somebody sells at a loss to you and somebody overpays from you. You are benefiting nobody but yourself. ^thats the entire pojnt of being a middle man. I routinely buy used mining equipment when the price is right (such as the S2 auction), and then advertise it locally for sale. I probably make $300-600/month through local resales of gear like the S3 or SP20, around 30% ROI. If MaximeAD can find both buyers and sellers at the prices advertised, I see no problem. OP makes profit, sellers ditch inefficient gear, buyers get local without needing to acquire BTC first or deal with overseas imports and delivery time. Capitalism at its finest |

just ordered one - Im a bit skeptical of the markup and large (2000) run quantity, but it looks fantastic. It wouldnt be the first 1oz silver coin ive spent >$100 on
wonder if we will see it fire-sale for $50 in a few more months though... IMO, the sooner mike melts down the remainder and keep ths total of these in circulation low, the better

not sure - theres no obvious reason for it to not push itself higher. Your start and max voltages are quite spread apart though, so it could take several hours to actually ramp up very slowly. It looks like your system uptime is only 1hr
try bumping your start voltage to 700mv - if it does down from there, its a sign of problem. if it stays there or barely rises, the system is likely very slow to adjust upward to nominal speed
OK, I'll try.. how much time it takes for the system to stabilize.. I never mined with ASICs before  It takes a bit of time to ramp up the speed. +1. Theres a reason the settings page suggests keeping your start voltage close to your max voltage. If they are more than 50mV apart it will take a few hours or more to slowly adjust. you should at least see the hashrate stepping up 5-10GH every so often (5 min?) |

@klondike_bar: Upset was mostly caused by not responding for months, but that is ok now and Terk is not mining 50%-70% anymore. It is 30% now. 0%-10% would still be better though. honestly, if clever mining reduced as much as you like, the hashrate of the coin would drop by 15-20%, becoming even easier a target for anyone with ~12GH of scrypt. At least with clever mining involved, you need about 14-15GH to overwhelm the coin and cripple it via forking or a range of other attack styles. IMO, new coins need to either be fast out of the gates to get a safe amount of hashrate, or be based on a new type of algo. It would not take much for a malicious miner farm or pool to bounce around various altcoins destroying them with 51% attacks for a few hours. Only reason it doesnt happen is that most altcoins simply are not worth the attack, which serves only to devalue them at the cost of time not spent mining BTC/LTC/DRK/etc (the leading coin for each algo) |

I stay with my opinion.
I thought it wasn't an opinion, they were facts that you and your lawyer were going to use in your clear-cut case? he spoke with his lawyer {this? last?} wednesday. his facts are strong and he will go to court to get compensation of his 50 shares scoff - two weeks later and giray never came back. I think he got laughed out of his lawyer's office when he explained he was after a few hundred dollars in compensation |

Bought my first SP30, second hand from eBay and with - FW: 2.6.1, start V: 0.655, max V: 0.75, max P: 1290W and 80% fan I can't get more than 2800GH/s stable (two ASIC chips auto disabled - Loop [5]: 15, 17) It looks like the device can't set the right voltage. No matter what voltage I set, it is fluctuating between 625-635, the PSU powers fluctuating between 700-800W and the temps are about 30 °C / 53,5 °C.

Suggestion: Managing a small number of SP20's at the moment, and love the page at http://start.spondoolies-tech.com/ to set them up and monitor everything. What I would appreciate is if there was some way to include the hostname or some other machine-specific information on that page. Using DHCP is the easiest way to manage things, but it's presently not possible to tie an IP address to any machine-specific information (beyond name or fw version #) eg: At the pool, I can see that a worker named SP2005 has gone down, but I have no idea which physical machine that is by looking at the start page and seeing all the IP's. KnowwhatImean ? they are 1 step ahead of you - http://www.spondoolies-tech.com/blogs/technical-blog/16385044-new-amazing-feature-in-2-5-54New amazing feature in 2.5.54
If you set in your pool user something like:
your0wallet0address0something_%%m...%%v...%%i
it will save it in cgminer.conf.template and then whenever cgminer starts dynamically creates cgminer.conf adress like this:
your0wallet0address0something_SP35...2.5.54...10.102.20.25
The nice thing is that now it is dynamic, so when you change IP or FW it will update the pool username. If you don't want username to change - don't use this feature. But be careful - if you have /etc/cgminer.conf.template on your machine DONT MANUALLY EDIT /etc/cgminer.conf, since it will be overwritten first time you run cgminer. |

It's gonna be tough all round with BTC holding in the low $200's and diff looking like it's going up again  Its even tougher for ppl holding their miners hoping to get ROI. Phillipma's opinion does not count because he got "free" electricity with his rent. I feel bad for ppl who just bought some miners tho.... however, it is a good time to get *some* used gear at good prices. I pay $0.09 USD for nighttime and $0.13 in the daytime/peak, so am still somewhat competitive. and im hoping to move into ~$70/kw/month colocation very soon |

I will continue to address you in public. You want to hide in PM, and I'd rather let the people who want answers see what you have to say. These coins don't disappear. If the coins are sold on markets, then it means that someone else bought them. So the coins still go to users who will actually use the coins. Nothing changes here.
The change is that at some point someone decides to buy a miner and use said miner to produce coins rather than buying them. This is most likely someone who will end up using these coins on a day to day basis, as that is what the coin was created for. When you're taking 50% of the coins out of the mining equation on any given day, you're taking coins out of miners hands. If you came to that conclusion at the time you now claim you did, then well, you were not successful in implementing it. I recommended DIGI to another NLG developer in a PM sent on Sep 14th and I recommended it to you personally in a PM sent on Sep 16th. One week later you announced switching to DGW3. Then you finally implemented DIGI with the beginning of Feb, four months later. You can't blame me for you being unable to implement good solutions for four months.
Actually exactly 5 months ago I recommended you the solution which you failed to implement then and finally implemented only 4 days ago.
I'm not a dev. I'm just a community member. I, along with many others, made numerous suggestions to the devs of the coin. It's true that it's not your fault that it took that long to make any changes, but it was your fault that we continued to struggle with your pool's influence on the coin during that time. Don't sit back and claim innocence. Your pool, your responsibility. I repeat: There is no difference wether we actually mine 50% or don't mine but control hashpower which is able to dominate your mining network. It's just the fact that somewhere there exists a hashpower which could take over your network - this is the problem. There are dozen of entities with this amount of hashpower, CM being only one of them, and you can't do anything about it. Wether we mine 50% blocks or 0% changes only perception, but doesn't solve the problem. Mining 50% blocks makes only the problem more visible to you. Not mining makes it less visible to you - and that's the only change. Us stopping mining won't change the problem - there still will be dozen of different entities each controlling enough hashpower to dominate your network at any time.
You're absolutely right. It's all about perception. You go absent for long periods of time. You let your pool rape our coin. You finally come back here to answer questions. When asked about the last 5 months, you sit back and tell us we should kiss your feet. Right now, my only perception of you is you're a greedy narcissist. I'm sure there are plenty of other people thinking the same thing in the NLG community. So perception... yeah, let's talk about it. If you come back to mining NLG, you're sending a clear message to the NLG community that even though the profit made from mining 50% of the NLG a day was a "tiny amount", as pointed out in your first post today, you're going to continue to mine it. The only message that you're sending with that, that can't be perceived any other way, is "Fuck NLG". Just leave NLG alone. Just lets us enjoy not having the cancer that has been your pool run our blockchain into the ground. If you find a solution to this - and somehow prevent the other dozen entities to be able to control your network, then I'm ready to discuss what more CM can do for you. Until this happens, I refuse to decrease my users profit only to change your perception of the problem, but don't solve any real problem. Your coin is as much vulnerable with someone mining 50% or not mining but being able to mine. Think of it like 10 people accidentally holding copies of keys to your home. You are vulnerable, because if they decided to, they can go in and out whenever they please (as: attack the coin). 9 of these people are holding their keys in their pockets (are not mining) and you don't see them. 1 of these people have his copy in plain sight (is mining) and it annoys you. You really should be worried that 10 copies of the key exist, not that you can see 1 of them. The thing is that you can't take these keys back and these people cannot give them back even if they wanted. There are dozen of entities with high enough hashpower to dominate your network and they won't disappear. Me hiding my key in a pocket won't solve your problem. And I won't throw my key away (where key being controlling enough amount of hashrate) as it would require shutting the pool down.
You're a trip. "If you find a solution to MPs, let me know so I can adjust my pool to beat it". LOL... what CM can do for me. CM can kiss my ass. That's what it can do for me. I still don't understand how you can possibly think you're helping anyone in the NLG community. You are seriously delusional. So again: I'm helping any way I can while running our pool at the same time. I reduced your max block time 20-fold. I recommended you the best readjustment algorithm four months before you finally decided to use it. But I won't stop mining NLG at all only for you to feel better, because it wouldn't solve any real problem.
Your idea of "cooperation with coin-switch pool" is the pool to stop mining at all. This is not cooperation and this is not going to happen. This is not coexistence. You would like us to stop existing at all. I can agree to solutions which decrease inconvenience to your users a lot (decreasing maximum block times from 580 minutes to 30 minutes) and don't decrease profitability of my users in a significant way, but I won't implement solutions which really don't improve NLG in any way (other than make you feel better) but decrease our users profitability.
No, cooperation would have been you not raping the shit out of our blockchain for 5 months. It would have been you not ignoring NLG all that time. 10%, 20%... anything besides the 50-90% you took everyday. If NLG is a "tiny amount" of the profit you make in a day, then it wouldn't be significant decrease in your miner's profits in any given day if you stopped. At most, you made a 1-2BTC a day mining NLG into the ground. Spread amoung how many users? You're seriously telling me that if that's a tiny portion of what you make in a day, you can adjust your mining to 10-20% and still not meet your profit goals by just mining a more profitable coin? Again, perception... it really just looks like you either don't care about cooperating with anyone, or you're really bad at math. I'm finishing discussing with you (and any other member of NLG community) in this thread because it's not the place for it - it's a support and announcement thread for communication between me and pool users. If your goal is to troll, then you can continue posting in this thread, but then I will simply ignore you and you will never hear from me again, let alone have a chance to ask me for something or try to convince me to something. If you really want to discuss something and try to convince me to something, then you already got my attention and show me that I should treat you seriously by stopping cluttering this thread and switching to PM.
I see you poked your head into the NLG thread, where people would LOVE to hear you talk about how much we should thank you for all your "cooperation". I'll see you over there from now on. -Fuse holy crap, you are THICK. Your issue isnt with Terk, its with your shitty altcoin that is seconds away from being crushed by any half-decent scrypt-mining farm or pool. Clevermining: - redirects user hashrate to what is profitable. - puts newly-mined coins into exchanges so that people can buy them (or not buy them, if the coin isnt worth anything) - is not 51% attacking anything NLG: - has around 1% of the total scrypt hashpower. This makes it insanely weak and suscpetible - has atrocious blocktimes, an issue that hasnt been resolved for months - is incapable of handling an influx of hashrate, and does not adjust its blocktimes properly in accordance You should be happy that clevermining is playing nice, when Terk could ACTUALLY rape and destroy your coin overnight very easily. Building a new coin based on an algorithm that's already in place and dominated by LTC is a terrible idea in the first place, and if Terk doesnt destoy it someone else will - either for profit or just for fun. having the added hashrate of clevermining is supposed to be a good thing, you just dont see that |

Has anyone published out the wattage draw to frequency settings in a chart for 110v?
Also...
I'm considering adding in additional S5s to some 2 Phase 208v 30 Amp Breakers. I have 4 of these circuits just sitting idle in one of my rooms.
Im a little unfamiliar with 208v to begin with, let alone 2 Phase. If I buy the simple distros for the sockets, use EVGA g2 1300w PSUs, how many could I plug in and feed of a 30a 208v 2 Phase?
Thanks!
Strato
30a x 208v = 6000W, of which you should try to keep the load below 5400W (80% capacity) since mining is 24/7 load. Thats enough to run 4 1300W PSUs, but not necessarily at full load. 1250W draw at ~90% efficiency means the PSU draws almost 1400W at the wall, and 4*1400 would exceed the recommended maximum of 5400W. It would be advised to try and draw 1200W or less from each 1300W PSU |
