Another question for those who've received their units:
Would I be right in thinking that the airflow is the standard of drawing in fresh air from the front and exhausting hot air from the back?
Roy -- Yep, that's right. Intake through the front grill and exhaust through the two fans in the back. I strongly suggest adding a fan pulling air through the PSU or additional fans in front blowing in before overclocking; with the default fan setup my PSU gets too hot to touch in 20C ambient. Also, you really must run with the top lid on or the heatsinks are bypassed in the airflow. Hmm, I wonder how plausible it might be to take the PSU out and run it entirely externally to the case, to avoid the airflow issues... But your idea of adding fans in front probably makes more sense. |

I have two for "Feb 1st week delivery":
# 337x
# 353x
is that your queue or your ordee number?? if its your queue then you have a long wait This is the order numbers (given in Bitmine emails). I wonder how can I know the queue number? (I saw on this forum lists of "queues" - where do people get them?) I understand some early "Avalon" orders have priority. I wonder who is receiving miners now and how many a day/week? Thank you, long-time-members, for clarifications! People found out by by means of e-mail converstaions with Bitmine, at least in the early days. I don't know if they are still giving this information out. I haven't received my miner yet (nor tracking information) but I did get e-mail today that my order was 'complete', whatever that means. I'm a reasonably early order - see the order list post. |

I don't want to trigger too much consternation, but this may be my 5-module unit's problem:  (which is why they don't sell the Platimax 1500W in the US) I'll be able to try this on a 240v circuit in a few hours... Just curious (hopefully not long before I find out for myself) but what kind of PSU did the 600GH unit come with? Also how long was it between getting notification that your order was 'completed' and receiving tracking info? Thanks roy |

[...] --bitmine-a1-options <arg> Bitmine A1 options ref_clk_khz:sys_clk_khz:spi_clk_khz:override_chip_num
The parameters are well explained [...] What is the significance of the SPI clock values used (4MHz vs. 8MHz)? |

Yep, both SMS and e-mail arrived five minutes after stopping cgminer.
One minor point: both messages say "last activity was at 2014-02-27 19:33:21". There seems to be a bug here in that 19:33 actually seems to be the time at which the alert was triggered. The last activity would have been around five minutes earlier than that.

Cool, thanks Josh. At some point I will probably look at implementing my own alerting - but would still be nice to get to the bottom of what's going on here.

Right. cgminer has been stopped for 12 minutes. Dashboard says last share 12 minutes ago. No e-mail or SMS received yet.
My hash rate is pretty low at the moment so I'm relaxed about leaving it down for a little while. If you get a chance, can you check the status again?
Thanks
roy
ETA: Last share now 33 minutes ago, and still no notification. I'm going to start mining again, but I'd love to redo this test at a mutually convenient time, so you can have a poke around when I'm in this state of being down, and dashboard clearly knowing I'm down, but the alerting system not noticing.

Right. Interesting thing is that the dashboard activity indication is always correct, which does kind of demolish my time zone theory.
Lemme try it again.

Interesting theory, Roy... however, the way shares are handled wouldn't allow disparate times to be entered into the DB. Each share server is it's own independent entity and has no relation to the master database, so if the wrong time were on the share server, it wouldn't affect the alert server at all.
However, can you test a different server, either US1, US2 or US3 and see if your problem clears up.
Yes, I intend to test that. I'll also try changing my timezone (what's the default?) Also, what is your pool name and I can look in the mail log and see if anything is being rejected?
Pool name is roybadami - my shares are certainly getting counted, as the payout is pretty much exactly what I expect based on my hash rate. roy |

Hi Josh, you may recall that many moons ago I complained that miner failure notifications weren't working for me (EMC username roybadami) and you took a look and couldn't see anything wrong (and even triggered an alert by simulating failure of the roybadami_test worker).
Well, I'm still having problems with this and I think I have some more useful information that might point to what's going wrong.
Late on Sunday evening (London time) I shut down my miners, and I didn't get any notification (which didn't surprise me - I usually don't). However some time during the night (apparently at 04:39 London time), I got a text message saying failed miner, last activity at 04:39. And then at 05:54 I received an email alert that also claimed last activity at 04:39 Europe/London.
However I *know* that there wasn't any mining activity anywhere near 4:39am London time, as cgminer wasn't even running over night. So this points to a timezone issue, I think. Somehow my share submissions are getting timestamped in your db many hours into the future, so the activity alert only fires if I'm offline for many hours. Could it be that eu.eclipsemc.com is recording last activity in an unexpected timezone, which is confusing the alerting system maybe? I have a suspicion that the problems _might_ have started when I started using the eu server.
Thanks
roy
ETA: Alerts certainly used to work for me when I first started using EMC. Plausible things that have changed between then and now are.... (very probably) starting to use eu.eclipsemc.com, and (quite possibly, but not sure) changing my timezone in my EMC settings from the default to Europe/London.

Always assuming the source is reliable, of course (I know nothing about upi.com).

UPI is reputable. Here is the original article: http://stream.wsj.com/story/markets/SS-2-5/SS-2-456759/ (google if paywalled) In the email interview with The Wall Street Journal, the French executive repeatedly responded to questions about the company’s solvency by saying that the matter is confidential. He did say, though, that the company had discussed its business model with Japanese authorities “to ensure that we are operating within the law here.” I found this to be very bizarre -- more so than unnerving. I can understand why people view Karpeles as malicious. At best, he is so mind-bogglingly stupid that he doesn't understand the effect of refusing to deny accusations of insolvency. At worst, he is intentionally manipulating the market. There are only three possibilities I can immediately see (please feel free to suggest any i'm missing): 1. He's been misquoted 2. He misspoke (unlikely, given he apparently said this repeatedly) or he didn't understand the meaning of the word (possible). 3. The company really is insolvent, and he knows it. And he is unwilling to issue a false statement to the contrary because he doesn't want to go to jail. I have no idea which of the above is the case (or if I'm missing a fourth possibility). roy |

In his email interview with the Journal, Karpeles repeatedly said the company's solvency was confidential but that it had discussed its business model with Japanese authorities "to ensure that we are operating within the law here."
If that article is accurately quoting Mark Karpeles that's a very bizzarre thing for any CxO of a company to say. I'll certainly accept that it could be a slip of the tongue by a techie who's not really a businessman.... Or possibly even that your typical techie doesn't precisely understand exactly what the world "solvency" means. But still, it's difficult not to read things into that. Always assuming the source is reliable, of course (I know nothing about upi.com). roy |

I was gonna write when I searched it turned up to be a hotel location.. lol looks like Mark wants to just stay in his room and get room service while Gox goes by the wayside. Is this dude still on the Bitcoin Foundation board?...
I see 'tower' in the building name. It's not uncommon for skyscrapers to be mixed use, with a mixture of offices and residential appartments, maybe a few floors occupied by a presigious hotel chain, and maybe thrown in a restaurant or two. This is common in major cities worldwide. So having an office in the same building as a hotel is not particularly unusual (if this is indeed the case). Still, it's an interesting development, and one has to wonder the reason behind the move. Would be very interesting to know whether the new premises are larger/more expensive or smaller/cheaper than the previous ones... roy |

The fact that Armory favors spent over unspent means it is less of an issue unless the wallet has no/few confirmed outputs.
If you mean Armory favours confirmed over unconfirmed, then so does the reference client, I believe. roy |

If the price moves... it's "manipulation". If the price doesn't move, it's "manipulation".
Not saying manipulation never occurs, but I suspect that most of what people put down to manipulation is just markets being markets.
