less than half actually - each rack of 9 units is just shy of a Terrahash (9*105GH) still - very impressive. is it bad that i want to bid an amount i know itll never earn back, simply because its red? |

okay, I know i said i would offer a sub-groupbuy, but at this time i do not see these being profitable enough to meet my own use requirements. However, at the next price-drop (whenever it may be), consider me interested. At that time i would be glad to organise at least 20 units for ontario residents with the option of pickup/dropoff in central toronto

I don't know why, but my bitfury won't talk to slush, so it is BTCguild for that, where it is happily mining at 26Gh/s. sad because Slush's pool needs all the help it can get lately.
you're telling me! yesterday i got confident and cocky that slush might NOW accept my bitfury. connected to the pool right in the middle of the goddam 15-hour block that hit CDF 99.8% or something like that. 12 hours later on another block, i see that with 1 worker it wont show more than 6 GH/s - back to bitminter i guess. ps: seriously, i know everyone likes the frequent payouts, but stop using btcguild. 33% of block solves is ridiculous, and they should increase their fees to >4% to force some people to use other pools. bitminter is only 1% fee + 0.3% if you want api use |

Anyone else hoping they come out with a new PCB colour for each batch/month? I would be at least 20% more willing to invest in equipment if it meant my rig became a massive rainbow   |

personally, im a little excited to see how they proceed. at this point, they are surely looking at how they can fire-sale all thier chips to get the liquidity and space to move forwards on gen2
based on the redhash avalon copy, we should see avalon systems in the 10-20BTC range very soon. I'd even be okay with converting my electric bill payments to BTC as long as i can get back some solid resemblence of my investment in a 3-5month timeframe using conservative calculations - course avalon systems will be the first asic to go offline when the power costs exceed profit (the gen2 competitions are about 700% more efficient)

Is the bitcoin boat sinking?
Looks like it, 15 hours for a block between yesterday and today... That is on Slush's Pool. If the difficulty goes to 200000000 (which is most likely) in 2 weeks time will it still be worth to mine on pools for small miners? Maybe we should all go solo? You won't get much out of pools neither solo but hey if you find a block when soloing it's all yours! Would be nice to hear what you guys think about it. Also I was thinking of investing in a Cointerra 2TH box but by the time I get it (Jan or probably "2 weeks time" after that deadline) the difficulty will be so high that you'd need 20TH to mine anything. And another query, if mining will become impossible/unprofitable for most people will Bitcoin lose its steam? i think we have a front row seat on the fall and collapse of bitcoin, and never thought i would say that , time to cancel my ebay orders for asic miners !!!!!!! People got greedy by making asic miners too fast , i don't think satochi thought this would happen , this wasn't in his maths Prove me wrong someone !! Your first problem is using eBay to buy a bitcoin miner. The second is I have no clue what you're arguing, that bitcoin is going to die due to asic, that asic is 'cheating', or that the growth curve right now looks any different from the one 3 years ago where using gpus was discovered Ok so there's a lot wrong with your response and i have no time to point it out , also cant you see the difference between a statement or an argument , i cant respond to what you wrote as you made no sense. i dont mean to be offensive but your kinda short sighted, using the argument of old dose not apply here, was the same situation relevant back then as is now ? No would be the answer! im sorry but alot of people on this forum dont know what there talking about they just post there un educated responses , im not interested in peoples opinion im looking for information, my issue is that the times now are not the same as before , forget the jump from CPU to GPU forget the hassle with MtGox , there in the past. TODAY there are new challenges with the network . i don't see it being sustainable in the near future for individuals like us and so far no one has given me a response to prove otherwise!!!!!!!!!!!!!! Or are all these issues with slush pool!!!!! i didn't say anything about cheating, i didn't say i was arguing , i didn't say anything about ebay being the problem , you stated that not me ........... In my opinion, we are quickly approaching the point where the upwards climb will appear to stabilizre a bit. a few more designs will come to the table, low-efficiency devices will stop being used (avalon, BFL), and we wont move past 28nm in the near future. Basically, I think that if you are using a calculator like the genesis block, the point where a 1w/GH miner starts 'losing money' is the point where we will stop the climb and become much more linear as systems turn off, switch to altcoins, etc |

Voodoo: oddly, the pool falls below 80Th/s and a block gets found. I wonder if the pool is having trouble dealing with the current amount of traffic, a scaling issue. or perhaps it is just coincidence.  Ive tried twice almost a week apart to get my 38GH/s bitfury to work with the pool, both with 1 and 2 worker accounts, and can never get past ~6GH/s even after 12 hours. yesterdays luck just made it all the more frustrating! |

Hello people,
I cleanly shutdown my Rasp Pi, and started it back up but then I noticed I wasn't able to connect to it any longer.... So I hooked up a monitor and it craps itself during boot with the following message:
PANIC: VFS: Enable to mount root fs on unknown-block(179,2)
Does this mean I have some sort of corruption with my SD card? Should I just go out and replace this one instead of trying to reflash this existing card?
I'm heading to the store now. Let me know what you think. Thanks for your help.
did you use the RPI's shutdown or sudo shutdown command? The last (and only) time i did that it started up mining just fine, but SSH was a no-go until i gave up and re-did the SD card. try reimaging the card before going out to buy one |

Just took a look at the results from 12+ hours of logging yesterday after pulling chainminer v1.2. The board looks quite stable and error rates dropped significantly (~1% over the entire peroid). I'm looking at 36 GH/s sustained over long periods just dc fans and no heat sinks. I've manually clocked all chips at 54 and have not noted any benefit in using the auto feature in v1.2. Now someone push the board up to 40  how are you making that sort of log? Im moving to manual tuning now, since most chips are stable at 54/55 with 1% errors and 36Ghash/37Ghash-nonce. if it runs well for the next few hours i will consider moving the resistance from 1.178 to 1.165 (before it gave me issues, but that was prior to chainminer update) Send Isokivi a tip for saving you the headache. ooh, not being a linux guy that still looks like a headache! (massive respect for the method/result though!). I can see 1.5hr averages at bitminter that work okay, but a longer-spanning solution would be nice. maybe the next sd update ill try to get the logger set up. right now, im seeing a very steady 36.5 Ghash at the pool over the last 3 hours, with the bitfury page suggesting it might be closer to 37 EDIT: after about 16hrs, looks like 36.8Ghash is the average hashrate, with the last 3hrs above 37Ghash EDIT 2: some new tweaking, and it looks like i am averaging 37.7Ghash I have gotten 43-44GH/s frome one board. Only 1 of my 5 h-boards did this for 24+ hours. My assumption is the chips were from a good bin. What I also notice is there is a HUGE variance in the performance of these chips. My question is: why? most of mine appear to run between 2.2-2.6 GH/s right now, so i suppose it could be an issue where some chips are just a little more cleanly packaged and operating. for 43GH/s, how is the heat/stability, and what voltage/resistance are you getting? (pencil mod i presume?) |

try: nano /run/shm/.stat.log to see whats going on with the chips. Maybe your h-board is not fully inserted
you probably have the wrong (default) ip in use. did you change to your home network (usually 192.168.1.249 / 255.255.255.0 / 192.168.1.1 for ip/dns/gateway)
edit: saw you can ping out, so your net is probably ok. try another pool like
mint.bitminter.com 3333 klondike.guest x
Correct me if I'm wrong but shouldn't the syntax here ... "klondike.guest" be "klondike_guest" for BitMinter (and BTCGuild). And Slush uses "." Or does it work both ways when entering workername? you're not wrong, i was. mint.bitminter.com 3333 klondike_guest x |

So how much have you guys earned in a week? For me it has been about 0.50-ish with 25GHs on slush (a tad lower than ideal... I lost a day or so due to miner complications).
bitminter i see about 0.13-0.17 per day at 38.5 GHs on my starter kit sounds almost too good to be true  difficulty just jumped i to 148M i think, making predictions now in the 0.1-0.14 range per day |

bitminter i see about 0.13-0.17 per day at 38.5 GHs on my starter kit I am not sure why my balance is so low..are you taking your future balance/number of days mined. Also, I set my difficulty to 32 did you to the software tuning or the hardware tuning? i havent checked the recent total, but I have difficulty 16, 2 workers at bitminter, bitfury set tuning (no autotune), and pencil modification. anyone pushed past 40 GHs on a bitfury card? When 'hot' (full operational temp/speed), I have a voltage of 0.808 per chip. When first powering on from 'cold' state, the voltage is about 0.790. It takes about 30min to reach 0.800. I have hashrate of 39 GHs and noncerate of 38GHs on average when 'hot' (full operational speed after 24hrs). Error rates are <3% on most chips, with 2 chips in the 4-6% range that i will likely tune from 55 to 54. heat is not excessive at this point, with some heatsinks in use, but i wont be pushing my chips any harder until i know that the dc converter can handle more voltage (30A top limit, which i want to leave some headroom). |

 The latest push earned me >39 GHash/second |

anyone using slush pool?
Yes. No problems at all... how? I created 3 workers at difficulty 16, couldnt get past 8ghash. 2 workers was no better |

^thanks for the link oh, and 38 Ghash/s |

anyone using slush pool?
general consensus is that slush's pool cannot handle bitfury devices. (dont know why, but noone seems able to do better than 30% of their optimal hashrate) its suggested to avoid btcguild due to thier massive network percentage. bitminter is a good site, and mines namecoins as well |

think of it as a delay. It will take about 12hrs to get up to the optimal (or nearly there) btc/block.
if you stop mining, you will keep seeing block payouts that dwindle for ~12hrs to 0 btc/block
