thanks! tuning best.cnf now.  false nonce and spi/miso err have to be minimized wright? I just went after the general errors, but I've had very low spi/miso errors all along. Basicly I rose chips that were showing 0 errors and lowered ones that had 10% errors (of valid shares). Hi, where in the rPI logs do you find valid shares? is that the same as nonces/round?? can I use nonces/round as a proxy for valid shares? |

EMC starts at diff 2 and increases it automatically to what it considers the proper value, you can't set it manually.
The rule of thumb for difficulty is, divide your Gh/s by 1.6, then round down to the nearest power of two.
60 Gh/s / 1.6 = 37.5 nearest power of two to that value is 32...
You mean 36 (6x6)? how did you arrive to 32? In addition, if I am using 2 concurrent pools , I guess I'd need to input my total hashrate divided by 2 in the formula to calculate it at the pool level, correct? I'm just trying to figure out why my hashrate is much less than my noncerate even after 24hrs of supposedly automatic share difficulty adjustment... |

I am using slush pool diff 26 with 25Gh/s starter kit and in pool I got 26558.817 Gh/s.
Do you know if I can change the difficulty for the EclipseMC pool? I don't seem to find where Is there a good rule of thumb to set the right difficulty relative to my hashrate? |

Why is my Noncerate about 20% higher than the pools' reported hashrate? My queue fluctuates between 1 and 8 :-/
What pool are you on? I'm using EclipseMC (us3.eclipsemc.com) and OzcoIn under Stratum and port 3333. In both pools the reported hashrate is lower than what I'm seeing locally as Noncerate... |

Maybe they won't last 10 years.... Maybe only 7.... The useful lifetime of these boards is measured in months at this point... OC FTW ! Heat those babies up  Actually, I stopped using my fans and the hashrate dropped like crazy. So, don't let them overheat. Some people here have said before that chips liking to run hot is sort of an urban legend after doing multiple experiments. I say keep them moderately fresh. |

We are pretty unhappy with the USPS (supposedly) 2 day delivery. Admittedly there was a holiday, but we saw a package that left here on Saturday take 5 damn days to reach Ohio. This is totally bullshit - we dropped the idea of using USPS. Everything is shipping FedEx. It costs over $100 to overnight a starter kit, but this is the only reliable way to get these kits to you guys quickly.
Expedited shipping will be FedEx overnight (domestic). Canada overnight might still work there - I'll check with Yvonne.
Non expedited shipping will be FedEx 2 day.
The problem we ran into is that USPS only guarantees 2 day delivery in "certain zones" - something they didn't bother to tell Yvonne when she was researching this.
Since Bitcoin mining is a game of days at this point, megabigpower.com will ship FedEx from now on, period.
We still have about 2 days of shipping left to do. I'm expecting more product tomorrow, but there's been a back up of stuff in AK customs. It should be cleared by now, but I can't tell by looking at the tracking info. It says expected delivery tomorrow.
Cheers,
Dave
Actually, Sunday and Holiday options can make it even in those circumstances but for an extra $$ ( I think there are some zipcodes where this might not work though). Here's a map of USPS "1,2,3 day guaranteed" Pretty Useful stuff: https://www.usps.com/priority-mail/map/As I said before, I still don't get how some customers nickel and dime on shipping (1 or 2 extra bitcoins if anything??) and then they bitch around why they don't get their packages soon enough. Love the idea of using FedEx too! We appreciate a lot your looking into this, Dave! |

I keep trying to shutdown my rPi and it seems to follow that process but soon it always ends in the login screen again and as a side note, without shutting down. Probably it's not caused by it but in the shutdown sequence I happen to see something like 'miner' not found or something like that.
Any reason for these issues? I use 'shutdown now.'

WOW - these boards LOVE warm temps.
I have a 400GH/s kit setup, and got the following:
300GH/s average rate over 1 hour - 2 x 120mm fan at 2500RPM blowing over them
420GH/s average rate over 1 hour - ZERO air flow, 78F ambient tempterature
This is probably the only instance I can remember where I have seen processors that do NOT like cooler temps.
Interesting, I am going to give this a shot... My server room is at 60F, I just took the fan off the 2 boards , lol.., timer started. Will update soon. You can fry your chips at those temps. Dave already has emphasized more than once to blow air on them and still people insist. Lol. At your own risk. Just sayin' |

Would that still need to solider/short some of those pins or that's meant to just flip the switch and that's it?? |

All you should need in your interface file for a static ip is below. One last edit reading back it looks like a few of just need to add the last line for DNS to make this work. Without the DNS it has no idea where to go thats why the dhcp is fixing it, its adding the DNS from the router #Put you own IPs here these are just examples auto eth0 iface eth0 inet static address 192.0.2.7 netmask 255.255.255.0 gateway 192.0.2.254 # This is for dns, my example is using the open-dns ips dns-nameservers 208.67.222.222 208.67.220.220 Yes, that last command seems to be the answer so as to not need any DCHP at all! Will give it a try. I think the values need to be hardcoded, because not sure if I can just set the gateway IP as the DNS. Probably not. I can perhaps just add a public DNS, like 8.8.8.8 correct? Thx! |

When people talk about fixing "errors": A) Do they mean SPI or Miso-Errors?? Other errors?? B) Do they mean the errors shown at the bottom summary section of the log or in the upper, detail section of the log at the individual chip level?? C1) Do they mean looking at this file ---> /tmp/.best.log or at this file --> /run/shm/.stat.log ?? C2) What's the difference between these 2 files? D) Is this the file that ultimately needs to be manually edited --> /opt/bitfury/best.cnf ?? E) When I look at the file /tmp/.best.log, one of the chips I'm looking has this ChipID: "[E:F]" , what the heck does that mean? My board is numbered from 0-16 (I have m-board v1.0) and even if it was m-board v2.0, why is the second part of the ChipID a letter and not a number?? F) How do I fix each of the errors individually? Just by changing speed/auto-tunning and/or relocating boards? Which change fixes which errors? G) Punin said to verify that the queue size in /run/shm/.putstat.log to be zero. However, my file (see below) has 3 records/values (3, 0, 0) which one should I look at, only the last one?? Queue length Getworks Nonces found Nonces submitted Server IP 3 55762 32058 32055 [0]http://127.0.0.1:8332
0 0 0 0 [1]http://127.0.0.1:8333
0 0 0 0 [2]http://127.0.0.1:8334
Many thanks for clarifying these questions!!! I'm sure I'm not the only one trying to piece together all these little details.. A) In my posts and testing I have been assessing errors in general, I havent seen a large number of SPI or Miso errors at any point and havent seen changes in it. B) I've been looking at errors on a chip by chip basis when tweaking the speeds. C) the stat.log is a log thats being rewritten every 5 minutes, the best.log is the best results that autotune has reached. I started off by copying the best.log to /opt/bitfury/best.cnf, which is loaded when the miner starts. D) Yes. F) The boards with the most Miso errors should be the last ones on the 4-slot bus so they do not interfere with better boards. G) You appear to have one pool in the configuration now and it's the top one. Great answers! Thanks, Isokivi! I think the only one you missed is E)  Oh, and on G) having 3 or a 9 value in the .putstat file, is that too small to be concerned or too bad? what's a reasonable range to have? Also, Dave said that pools are parallel and not failover, do you have a sample file on how to format the pool file. I'm just accessing the rPI IP per as Dave recommendation but would love how to edit the file directly. The current pool file location provided by Punin in my SD card is empty so not sure if there are 2 files managing pools in my SD. |

Same here. This looks correct and allows me to connect when I set my laptops ip to 192.168.169.177 and direct connect the ethernet cable to the rPi but won't work when connected to the LAN.
auto lo
iface lo inet loopback
iface eth0 inet static
address 192.168.169.175
netmask 255.255.255.0
network 192.168.169.0
broadcast 192.168.169.255
gateway 192.168.169.168
allow-hotplug wlan0
iface wlan0 inet manual
wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf
iface default inet dhcp
I hate dynamic IP. I like a predictable IP. This issue is probably related to lack of DNS definition but then the question is how to setup DNS??? Does anyone know how to make static IP work?? |

Orders 76 and 78 - shipped! Email sent about 10:00 PM PDT - they're working late. According to the tracking, my order was shipped out on the 3rd, and it's almost here already...  wtf... my order shipped saturday and the tracking just updated today and it's not even in my fucking state yet. It even says Scheduled Delivery Day: September 3, 2013. Fuck USPS. If you really wanted your order soon enough, why didn't you pay the incremental Overnight expense?? We can only bitch around time or price but not both :p |

Thanks. Dave.
The M-Board-to-PCi-e Ring terminal adaptor (for version 1 of M-boards) should come along with the m-board, correct?

#13X still sitting at CC paid, i will be a little dissapointed if it doesnt update tonight. Punin shipped pretty much every single on of his orders within 2 days, and dave has had the entire set of m and h boards since friday
Dave decided to match the card to the orders so that he uses least number of cards to fullfill orders. Imagine 1000 cards on the table, sort out which ones are 25GH+, 20-25, 15-20, 10-15 etc. That takes time (and money). Punin decided to KISS. 2 cards per m board, boom, go. Next. I like Punin's approach way more. He doesn't nickel and dime with today's mining difficulty and I feel pretty good about my soldering skills in case of board issues. Yeah - but no way am I signing up to teach all the other customers how to troubleshoot these rigs. I agree. Good call, Dave! I'd probably do the same on your shoes. You'd get a lot of calls/emails otherwise. I'm pretty sure on the quality side you have the edge for sure! |

Don't forget that Dave might be reviewing/testing boards probably more thoroughly than Punin. |
