I'm starting to play around with the static difficulty setting on my S1's (I'm mining at coincadence ATM). Through yesterday I had left it at the default, which according to the monitoring was "1,000".
Last night I changed it to static difficulty of 128 (BTCaddress+128 in the miner config).
Before the change I had 4 shares over the span of 6 hours. After the change I have had 10 shares in the past 9 hours, and my BTC earnings per block went up by .02BTC. Now, I've not had a share in 2 hours at the moment, so we'll see what happens through today.
In addition, I am noticing that my Rej% is down an average of 2% from about 7% to about 5%, and the Stale% is now flat 0 across all of them, where it was on average about .2-.5%. This to me is a good sign I think.
From what I understand bandwith and latency to the local node does help with a lower diff setting, because you're getting and submitting shares more frequently. If I'm correct in thinking that, then it makes sense. We're physically close to coincadence so my latencies are low, and we have ample bandwith to allow for lots of traffic at the lower diff setting.
I may take some of the group and set it to 256 diff and see if any of the numbers change for the S1's. We just ordered a bunch of S3's from batch 5, so I will probably try a 512 diff to start with when those come in next week and see what happens.
Setting +128 sets your pseudo-share difficulty. All it does is tell the p2pool node to accept shares from your miner of 128 difficulty or higher. The effect is to make the graph prettier at the cost of increased bandwidth and processing done by the node to handle the extra shares your miners are sending. Setting actual share difficulty is done by /128. Unless you set this to some value higher than the share difficulty, it makes no difference to p2pool since you need to find a share of about 4.5M to even get on the chain. The only time you'd want to set this value is if you've got a much higher hash rate than average on the node. You seeing 10 shares in 9 hours is nothing more than luck - not because you set the difficulty level. |

Hitting the faucet takes less than a second. Sure, I can only go to freebitco.in once an hour, but I've spent a total of 2 mouse clicks of time in that hour. How many faucets are there? I really don't know the answer to that question, so I'm hoping someone can give a number. Is there only 1? Are there 10? 100? Let's just say there are 10. Now, I'm making 3000 Satoshi for about 10 seconds of my time per hour. I'm pretty sure I can spare 10 seconds an hour... heck, I could even do that while wandering around collecting cans after I finished my shift at McDonalds  . |

I am looking for Owners of bitcoin mining pools who are looking at datacenters. I work at Cogent Communications. We are starting up a colocation team and I have been slected to be on the team. This allows me to offer pricing that is otherwise unavailable and unbeatable in any of our 44 owned and opperated DC's in North America and Europe. We have our fiber pulled into hundreds more DC's globally. If you've got a quote. I'll beat it. I'll save you money and allow you to make the most profit while mining. Email bfair@cogentco.com. Thanks for your time. Brian I'm a bit confused - especially the part I bolded in your post. Are you only looking for pool operators to run their pool's servers in your data centers, or are you looking to host actual mining hardware for the average Joe? If the latter, what kind of equipment would you be looking to host - cabinet-ready miners like the SP10/SP30/S2/etc, or would you be able to handle non-standard form factors like the S3, which would need separate power supplies? |

Thank you very much for all of your replies.
I am not new to mining, I am a GPU miner, who is selling his 17 GPUs and moving into the ASIC realm.
My reasons for mining are to hold, and hopefully have a decent savings later on in life. (unfortunately I have had many issues come up recently that forced me to sell every coin I have made, which would have been around 20 BTC, this is very upsetting, but life goes on)
I think, after this post and many others reading, that I am going to wait until I sell my hardware, and pick up some s3's, it seems like the best way to go, as no, I don't have free power, but I do have relatively cheap power, and a really nice circuit in my house that's capable of running quite a bit of hardware.
The s1's I am speaking of are a local deal, so there would be no shipping.
I just think that the power usage of the s1's is too high, and that getting s3's is a better idea.
Thanks again everyone who replied!
You're certainly correct on the power usage of the S1. Stock clocks call for 360W at the wall. Most everyone reported the S1 consumed at least that amount. Overclocked, and you're 400 plus. The S3 is 340W at the wall for 440GH/s. Less power, about 2.5 times the hash. |

I have the opportunity to acquire 5 antminer s1's for 130 dollars a piece. I am simply looking for advice here as to whether you guys would go for it, or wait a little while and buy some s3's? Those are my two options, I know the s3's would be better on power, but overall what do you think, should I go for the s1's or pick up some s3's about a month down the road?
Thank you in advance for your opinions!

Well, let's take a look at some numbers. First, a few assumptions: You pay 0.00017 BTC per kWh, difficulty will jump 10% every 2016 blocks, BTC remains at $600 for the duration (mostly so I don't have to use variable rates for power) and you can start mining immediately (pretending you have the S1 in hand right now). Also, I'm going to assume the price of the S3 drops to 0.6 BTC in a month and you start mining with it on 9/1. Oh, and I also assume you already have a PSU capable of driving the units. S1Up front cost is 0.22 BTCExpected ROI after a month: -0.1267BTCExpected ROI at EoL (1/14/2015): 0.004746BTCS3Up front cost is 1.2 BTC (MOQ from Bitmain is 2) Expected ROI after a month: -0.7747BTCExpected ROI at EoL (5/27/2015): 0.3253BTCTake this analysis with a grain of salt - I assumed a few things that may or may not happen (especially the constant 10% difficulty increase). |

Anyone that updated firmware that was overclocked? I have one happy overclocked a little. I'm just scared to mess with whats working. Wondering what you overclocks think of newer firmware. I don't care about beeps just speed  I dropped the new firmware on my batch 1 units the day it was released. It had absolutely no impact on their ability (or, really lack thereof) to over clock. My batch 4 units all came with that firmware installed from the factory. I have not yet tried to over clock the batch 4 units, although every one of them is very happily hashing at 440GH/s, so I might tweak them a little and see what happens. good news on the batch 4 gear. I have 2 coming today I want the same results 440 at 218 freq. and the new firmware So, just for fun I've tried a few different clock settings on the batch 4 gear. One unit clocked successfully up to 250 with all "o" chip status; however, the HW error rate was quite high, and for some reason it never made it above 400GH/s. I have since set that unit to 237.5, and it has been hashing at 475GH/s for about 3 hours now. Another unit at 250 immediately started showing "x" in a few chips. I set it to 237.5 and it, too, has been hashing at 475 for the past 3 hours. Yet another unit is like my batch 1 units... just won't over clock at all, but is very happy at 218.75 and 440GH/s. One thing I have noticed... my batch 1 units have almost nonexistent hardware errors. After hashing for the past 3 hours, one has an error rate of 0.0046% and the other is 0.00079%. All told: Batch 1| Clock | Speed | HW Error % | | 218.75 | 440.33 | 0.0046% | | 212.5 | 428.36 | 0.00079% |
Batch 4| Clock | Speed | HW Error % | | 237.5 | 476.14 | 0.1079% | | 237.5 | 475.11 | 0.1932% | | 218.75 | 441.72 | 0.0166% |

Here is a question? What is up with the name Discus Fish?  I am sure it has some meaning in Chinese but I don't get it (being from New Zealand). It does not appear in your blocks, I am just curious to find out how it came about. Neil Google Translate gives "Fishpond" for the Chinese in the post title. I have no idea how/why this pool is referred to as Discus Fish... |

This is a problem...on this particular boot its showing a time difference of 24 minutes which causes this result...Im sure I have seen as much as 8-9 hour difference between the uptimes
This miner was rebooted only 3 minutes yet the miner status page claims its been running 27 minutes which is impossible and the "hashrate" shows it...so how often is the cgminer process restarting behind the scenes or what is going on here BITMAIN?
How did you reboot it? Web UI, or ssh? I see this whenever I reboot through ssh... or if I just turn off the PSU. If I reboot through the web UI, or if I use the poweroff command in ssh, everything comes back up properly. |

Are people happy with their S3 units on p2pool?
If you're on p2pool, are you using the stock queue option (4096) or did you change it?
I've got units both at stock 4096 and changed to 1. I haven't noticed any differences in hash rates, although the hardware errors seem to be a bit lower on the units I set to queue of 1, but I need to change the stock units to 1 to see if the lower error rate is truly a result of the change or not. |

ok cheers ! thanks for patience with a noob like me. now setting the 2nd PSU will be a piece of cake  First, congrats on your foray into mining... it's addictive. Each S3 requires a minimum of 2 PCI-e connectors. The RM1000 has 8, so you're good to go. The PSU has 6 PCI-e connection points which are clearly labeled. You'll also have 6 PCI-e cables, 2 of which will have a "double" end giving you the total of 8 available connections. You plug the 8-pin end into the PSU, and the 6-pin end into your S3 (the 6-pin end is actually a 6+2 setup... pull the "2" away and plug the 6 into the S3). Make sure you plug 1 PCI-e connector into each side of the S3... don't plug them both into the same side. For the paper clip, go here: http://www.corsair.com/en-us/rm-series-rm1000-80-plus-gold-certified-power-supply and click on the "FAQ and Support" tab, then the "PSU Paper Clip Test". Scroll down to see a picture of the ATX plug with the proper holes highlighted. Shove your paper clip into those holes. |

In a nutshell, yes. To add a block to the chain, some miner somewhere has produced a share with difficulty of at least the current target (18,736,441,558 right now). At the end of January last year, that miner would only have had to produce a share with difficulty of at least 2,968,775.
Genesis block (block 0) difficulty: 1
Block 100000 difficulty: 14,484
Block 200000 difficulty: 2,864,140
Block 300000 difficulty: 8,000,872,136
Latest block (313500 at time of posting) difficulty: 18,736,441,558

I'm fairly new to the mining game and missed the period of time when ASICs and high powered miners started to hit the BTC scene. I'm trying to get into the new ASICs for scrypt and was trying to figure out what type of impact a large increase in hashrate would have... 1) Is it a fair assumption to say the new ASICs into scrypt would have the same/similar effect it did on Bitcoin? 2) If #1 is true - What type of effect did the large asic introduction have on the BITCOIN market, community, and price? 3) Is there any other things that could be expected from these changes that would effect the bottom line (ROI) that I haven't mentioned? Any info would be awesome! Not sure if this thread belongs in alt currencies or speculation, so apologies if I posted in the wrong spot. Also - If I used affect/effect incorrectly don't bash me for it, but feel free to correct me! You used effect correctly in numbers 1 and 2, but incorrectly in number 3. To understand the proper usage, you need to understand the meanings of the words: Affect - to bring about, or to produce, a change in something Effect - the result of something, or the ability to bring about a result Generally, and a pretty good rule of thumb to use, affect is a verb, and effect is a noun. Using this approach, you can substitute words in your sentences to see if they still make sense. Substitute "consequence" for "effect" and "transform" for "affect". ASICs affected mining difficulty. ("ASICs transformed mining difficulty" makes sense, whereas "ASICs consequence mining difficulty" does not) The effect was a massive increase in mining difficulty. ("The consequence was a massive increase..." makes sense, whereas "The transform was a massive increase..." does not) As with most everything else in the English language however, this is not always the case, which is why I started by stating you need to understand the meanings of the words. For example: Even though she was sad, she displayed a happy affect. You can effect change by taking action. So, how will you be affected by the effect? |

hey just wanted to know that is Bitcoin Cloud Mining profitable?? I am new here just bought 100$$ btc and wanted to invest in mining.i have invested like 5$$ in betarigs.com but after 10 min .i could see that i was losing what i invested .so i started to do research about mining and know that the actual miners cost like 1000k to 2000k $$.it was too much for me so searched for some cheap options and found out about Cloud Mining .I just wanted to know about it a little bit more and if anyone can help me get started with it any good sites to start could mining and is Bitcoin Cloud Mining PROFITABLE!!! Thank's in Advance!!  EDIT: I am thinking to buy this http://buy-antminer.com/antminer-u2 .will it be profitable to invest in the device?? First off, no, cloud mining is not profitable to anybody but the guy selling you the cloud mining contract. Secondly, congratulations on your purchase of BTC! That Antminer U2 is a fun little USB stick miner, but you certainly won't make any profit from it, especially at the completely outrageous price quoted in that link you gave. The U2 should cost no more than $10 - $15. If you want to try out mining and have your very own hardware just for fun, with your budget I'd suggest something like the Rockminer R-box (32-37GH/s for about $65 - $75). Lastly, your expectation of being able to just spend $70 and somehow having that magically multiply itself from mining is unrealistic. Mining is not a get-rich-quick scheme. It is an investment. And, just like any investment, it can either be rewarding or not. Honestly, since you've already purchased the BTC, I would suggest you just hold onto it, rather than trying to find mining hardware with it. |

Hello ! i'm new in this big world of cryptocurrency , i want to start mining just for fun ,, for undestand how this work ... can you explain me .. How can i get start ??
I have a simple Personal Computer .. ... Which software i need or can i to use (miner) ??
which cryptocurrency can i mining ( i do not give a ... if i do not earn $ i think it's impossible with my tech ) but just for fun ..
What exactly are you trying to get out of mining, then? I'm not even sure if there are any WinXP compatible software builds out there at the moment... speaking of Windows XP... you do know that the product is no longer supported, right? No more patches, security fixes, anything coming from MS at all for it. You might want to consider upgrading that, rather than thinking about mining. |

You can check out Corsair's website for the paperclip test instructions, complete with pictures of which pins on the ATX connector to use: http://www.corsair.com/en-us/cx500-80-plus-bronze-certified-power-supplyLooking at the cabling pictures it is difficult to tell if the PCI-e connectors are two separate, or one cable with two connectors. I know that the CX600M (the modular one) had a single PCI-e cable from the PSU with 2 PCI-e connectors on it. I also know that this setup worked absolutely fine with the S1 (I had it running for months with an over clocked S1). If you don't want to do the paperclip thing... or strip wires and make your own jumpers... there are a number of vendors out there who make connectors. For example, you can pick one up from here: http://minersource.net/products/psu-jump-starter or you could plunk down the $750 to get 500 of the brand new jump switch from Bitmain: https://www.bitmaintech.com/productDetail.htm?pid=00020140731043909819C9CL7qf4064A. If you do, I'll buy one from you for my HX1050 |

For most mining gear you only need an Ethernet connection to run your miners. You access your setup and monitoring software via webpage on a computer or other device. No USB necessary.
Wait are you talking about cloud mining? I'm talking about a physical piece of mining hardware I have attached to my laptop. Lol, nope. I'm talking about hardware mining. Gear from Bitmain, KNC, Spoondoolies, Bitfury, Cointerra, BitMine.ch, etc. do not use USB to access or control the hardware from a PC. They have their own built in controllers (often RPi or Beagle Bone) that you connect to via ethernet. BFL does require connection to a host PC (or other computer device) via USB though. But you don't want to go there. Oh wow, I wasn't aware of that. I always thought you needed a "host" computer. Anyway, is there anything simple that can be plugged into a USB and not cause too much heat? and again can you do more than 1 miner in 1 laptop? I'm not very familiar with Rockminer's gear but I think they may have a small USB miner. And yes, you should have no difficulty hooking several up although you may need a USB hub. Any of the USB miners will do that (Antminer U1, U2, Bitfury, IceFury, etc). Get a powered USB hub, hook that into the USB port on your laptop and run your favorite mining software. Also, the R-Box by Rockminer works the same way... plug USB cable into your laptop's USB port. |

Man I tried.. They said driver would not be back until 7:15. They close @ 7PM. lol. I told them to hold it and I'll just pick up there tomorrow. I hate when this happens. At least it's in town and not stuck in a shipping fiasco like some. Missed my UPS guy and he didn't leave them. Called in and I'm going to try and pick them up from the UPS office this evening. The one time this dude comes before 6PM.
if ur packages arrived at the warehouse, go call the UPS, and ask them if you can pick it up by urself now u'll always ended up dissapointed if u want to wait them to deliver it trust me, just pick it up urself, then mine immediately I got mine today, heard him from the basement with his squeaky ass brakes. Ran upstairs to see him "tossing" them up to the front of his brown van, and then deliver them to me. He got my signature, verified the address, I asked him if he needed any ID and he said "no, whats your last name".. Satisfied with my answer he said "Have a nice day." I told him you too and went inside. Then what happened? I know, I'm gripped, the anticipation is killing me. After going inside, I realized these were heavier then I wished to carry at that point in my life. So I set both boxes down, rubbing my back gently, as I can get some aches from time to time. Staring thoughtlessly at my new miners, still wrapped in their plain brown boxes I remembered 3 things. First, I really did not like the new waitress at the restaurant down the street, she was quite ugly. Second, I was thirsty and wanted a beer. Finally, I really had better get these things down stairs, before my wife arrived home. OMG...hahaha! Continue on please! |

Well folks, it's official! I hope you are all as excited about this as I am ------------------- FOR IMMEDIATE RELEASE: 7/31/14 CoinCadence.com Acquires P2Pool.org Domain
And Announces Plans For New Open Source P2Pool Dashboard Stamford, CT: Today, CoinCadence.com, a Bitcoin startup focused on mining decentralization and transparency, announced that they have acquired the p2pool.org domain name. p2pool is a decentralized mining pool that creates a peer-to-peer network of miner nodes working together as a mining pool. p2pool is open source and any miner may host their own node and join the pool. Milk House, LLC’s managing member said, “We have been working with the p2pool mining community to develop the most data-rich and useful p2pool dashboard available at minefast.coincadence.com. With the acquisition of p2pool.org we now have even greater capabilities to promote the growth of p2pool and strengthen the decentralized mining network.” The company plans a staged roll-out for the new p2pool.org website: ● The existing p2pool.org site will remain as-is until the new site is complete, mining will not be interrupted. ● By September 1st: A fresh home page for p2pool.org explaining the benefits of becoming a p2pool node operator, a public Coin Cadence p2pool node with 0% fee for those that are not able to operate their own node, and links to accredited p2pool resources and guides. ● By November 1st: Open source version of the data-rich Coin Cadence p2pool dashboard released including real time data from p2pool and the Bitcoin blockchain and an API that provides historical data. ------------------- Hey windpath, congrats on the acquisition!!! You've done a great job so far and have been a highly valued contributor to the p2pool experience for miners. I know when I'm not mining on my own node, I'm on yours. I'm glad I was able to contribute to what is, at least in my view, the best p2pool experience going. I wish you all the best, and look forward to your upcoming release. |
