Glad I found this thread, just had a LTC transfer not show up, though everything looks correct in the blockchain. I emailed customerservice@vircurex.com this morning too, so far no response though. |

I believe the theoretical limit of 127 devices - have yet to verify this myself tho  What is the highest that someone has proved? I would LOVE to see a pic of large amount using this. I've read something about this, rpi can handle with a decent percentage of hw errors 40 block erupters, over 40 CPU load is always on 100% and hw errors % increase On a related note, can anyone chime in on how stable the RasPi is as a mining platform? I've heard that the RasPi has some stability issues (especially when dealing with USB), though I've never actually used one myself. I'd be inclined to order one if they can handle ~40 USB Erupters for 24x7 stably. |

We are so doomed.

I can log in bitfunder. But I can't log in weexchange.
What's the problem?
Can't login to either at the moment, both just loop me back to the main login screen with no error. |

Post pics of the the whole setup.
 Behold, the FrankenMiner... 2x7990's, 1x7970 & 1x6950, on a single MB. |

Everything shipped out for group 2. Stale needs to come pickup, that's it. now to deal with group 3 and the impossible to verify messages... (after I get back from FedEx location)
PM'ed, thanks! |

Still up for me connecting out of Los Angeles.
I'm on the eastern side of the US using cgminer 3.1.1 and it's not connecting here.  I have two machines connecting to stratum.bitcoin.cz:3333, one works, the other does not. Can telnet to the port successfully though, so I suspect it's authentication related. |

And yeah, bitinstant allows cash to be deposited directly to exchanges, or straight to a destination BTC address of your choosing.

MikeMike, 1 unit on this group buy is 2.2218, so 2.2218-2.03636 (you sent) - .0299 (your overpayment in group 2) = 0.15554 due when you get a chance, please send the remaining 0.15554 Thanks, Canary I'm trying to verify an account with coinbase. Or if there is another way I will pursue it to get the payment for another 4-9 pieces. Once order closes and I did not have ability to get any more BTC to fulfill at least 5pcs I will send balance. This way it does not get too confusing "on my end". Hope my reasoning explains the amount I sent. I use www.bitinstant.com when I need bitcoins really quick... you can use a money gram location and as soon as you deposit cash, bitcoins are sent to an address you specify on your order. Disclaimer: I do not assist with using bitinstant. Drolla/bitinstant I believe was closed down in USA Dwolla wasn't actually closed down, but their accounts for MtGox were seized. They now require your SSN to do anything.. Bitinstant is alive and well, though they certainly have some fees for their service. I've used them in the past couple days to get in on these orders. I'd definitely recommend Walmart for the local payment site, as they allow you to pay with either cash or a pin-based debit card. The others seem to only accept cash. OK thanks, Do you mean I can "With a SS #" and bitinstant sent money TO ""ANY BTC ADDRESS""  Or do I not need a SS # with just using biinstant ? Bitinstant does not need a SSN, just name/address/phone (they don't seem to check an ID even). Dwolla though changed their terms of service a while back apparently. Because of these group buys I was looking to buy some BTC, and was looking for ways to do so (last time I did was back in the Dwolla/MtGox days). It seems that Dwolla now requires a SSN for pretty much anything (and even with a SSN, you still cannot send to MtGox). Seemed a little excessive to me. I was surprised at how few options there actually are to buy into BTC. Bitinstant certainly is decent (their payments do get processed very fast, virtually instant). Still, ideally I think you could ideally have a credit card -> BTC processor. I understand there isn't one because of the potential for chargebacks, but it seems to me that BTC transactions would be very easy to prove to Visa/MC. |

Does friedcat ship from within the US? or are they shipping from a warehouse in China (I assume so since he's using DHL)?
China I believe. |

Our order has shipped. I've received the DHL tracking number.  Wow, that was quick, hopefully customs is nice to us. |

I used 6990 before for hashing wpa2, mybb and some other hashes so i really luck them problem is its very hard to find (at list it used to be) i sold my hash box few months ago, never tried to mine some bitcoins (regret it now) And 7990 looks very sexy and expensive too, Im thinking to get one too in the future. I was very close to but butterflylabs Jalapeno last month, actually I did but my bank canceled my card strait away,had very long conversations with them on the phone... Now I got feeling all this ASIC machines a bit cloudy... I understood you done pools and solo too? at he same time? Thanks for answers guys I really appreciate it. I understand why you saying i should mine in pool but with mine hash rate Im getting around 0.02 bitcoins a day. By mining solo i might get lucky (very very hardly ). I bought today 6990... with other 2x 5770 Im hoping to get around 800 M/hash But which cards you could suggest to me? I'm basically in the same arena right now, as I'd like to expand - but: Historically I've liked using GPUs simply because they hold a pretty good resale value, with the downside being the power draw. Though with the rates being shown with some ASICs (Avalon = 60Ghs), I'm hesitant towards buying any more GPUs. * I do like 7970's for BTC, though I have tried LTC with the same cards, and optimizing them can get weird. For BTC though, I haven't had any real issues with them. * The 7990's I have are expensive, though they certainly are fast (~1,300Mhs each). However I had one die a few days after receiving it, which is painful waiting on an RMA (knowing how much they cost, and having lost 1,300Mhs of capacity). Powercolor received the RMA, and responded that they didn't have any replacements available - and that it would take 3 months for a replacement. I doubt I would get any more 7990s for this reason alone, and probably will never go Powercolor again. I'm watching ASICs pretty closely, though the one aspect that has me nervous is the longevity of ASIC hardware. Spending 75BTC on an Avalon is a rough sell as-is, could you imagine it dying after a month? Maybe Avalon has a smooth RMA process, but I'd rather not count on it. I love the idea of the Block Erupters ( https://bitcointalk.org/index.php?topic=195004.0), which basically negates the risk of a single massive failure. But 2BTC per 300Mhs is expensive, though if these dropped in price a bit I would probably stock up on 'em. Na, I've always gone through a pool. Primarily Slush, though Deepbit for a short time and some at Coinotron as well (to play around with scrypt mining). When picking cards I tend to weigh the resale value pretty heavily, so I always go for the latest / fastest cards. My logic is those will retain the most value for the longest period (though some of the older cards are technically more energy efficient). I do think ASICs are real, though there are certainly a lot of scams out there. If the Jalapeno was shipping today, for 5GHs @ $300, they would be flying off the shelves. I first saw an advertisement for them sometime last summer, hard to believe it's almost a year later and they still aren't shipping in quantity. |

I understand what you mean with 337Mhash/sec rate it probably will take me at list few years to find something. But is it possible? is config right? At the moment Im just learning and setting up and trying to understand everything
It is completely possible to solve a block with that hash rate, just very improbable at this point. To give an example, I started around May of 2011 with a measly 140Mhash/sec. Basically I've been re-investing the proceeds into more mining gear, to try to make this self-sufficient (largely have been successful). * Doubled to ~300Mhash in August 2011 * Quadrupled to ~1,200Mhash in January 2012 (with the release of ATI's 7970s) * Added more throughout 2012/2013 to leave me with the ~4,400Mash I have now. In total, I mined @ Slush's pool during this entire time, and he has me down for 8 blocks found in total during these two years (timestamps below). Really it wasn't until I exceeded 1Ghash/sec that I started solving blocks, and even then the difficulty certainly wasn't 10+M. * Timestamp 2011-10-23 21:50:22 * Timestamp 2012-02-02 23:20:54 * Timestamp 2012-02-23 13:53:07 * Timestamp 2012-02-25 20:54:46 * Timestamp 2012-08-12 12:23:03 * Timestamp 2012-09-08 03:53:05 * Timestamp 2013-02-12 03:18:16 * Timestamp 2013-03-02 03:17:07 Hope this helps. |

You might as well forget solo mining with a 5770 for bitcoin. Not enough hash power. You will never find a block competing against Asics. You may want to find a mining pool.
Hit S for settings then save a config file then post it.
Im getting few 6990 cards for now, I try to look for some Asics but all looks like big bubble just pr-ordering Here sreenshot after i left to run for 56 hrs  Why it all 0? You saying not enough hash power? What hash power should be? Here is config file: {

From the screenshot you averaged 337Mhash/sec for about 2.5 days. My rigs together average ~4,400Mhash/sec, and I don't even have enough to solo mine effectively. I would second the recommendation to look at pooled mining (Coinotron is good, I've used Slush for over a year and am happy). With pooled mining your rewards are no longer based on the blocks you've found, but is based on a mixture of the blocks that are found by the entire pool along with your contribution. You'll be much happier with pooled mining. |
