For all those who measure the voltage applied to chip on H-Boards, as a minus (GND) use for this GND on the H-Board instead power suply or M-boards. These differences arising from the resistance of sockets and contacts on a card. They range tenths of volts. It turns out that, instead of 0.865V is 0.825 or even 0.760 Therefore, the chip receives voltage measured preferably on next chip capacitors or capacitors next to coils (PULSE) of DC-DC converter labeled C12 to C16. https://www.dropbox.com/s/rxhufkcy1tgtwx2/20131110_220257.jpgCheck voltage on top of the inductor (grey box with PULSE printed on it and any of the GND pin from the PCIE power supply)
Just FYI... There is a small problem with measuring voltage like that, but it's still the easiest way in a crowded rig. There's a significant and varying voltage drop on the ground line between the power supply and a card. Just between the M-board's GND terminal and a slot's ground pins, there's a drop of between 0.023v (slot 0) and 0.067v (slot F) on my v1 rig. So while it may look like you're running a card at 0.900v when measured the easy way, it could actually be as low as 0.833v. And I didn't even account for any further drop from the slot to the chips' ground plane. |

I have been using bfgminer since i received my bitfury instead of chainminer and find its a lot more stable and seems to work fine with all the pools i have tried as it does stratum itself there is no need for the proxies.
This seems reasonable to me as I am a long term cgminer user. Any tips on how to set it up? Sorry been tied up have you got it working ? according to bfgminer readme, it says there is no thermal shutdown regulation. do you have heatsinks installed? I don't think chainminer is any different. AFAIK, the boards have no temp sensors anywhere. |

Where can i find the latest firmware for the chilis? I have one that won't start hashing and is reporting to cgminer as a BAJ instead of an ls. I figure it was a bad flash or something stupid like that as it's brand new.
which is the newest firmware?
any link/

In other words, if I give him 5 BTC for assembly that never occurred, then he has been sitting on 5 Bitcoins that were never used for anything at all this entire time.
...
He probably sold the BTC and bought all the components (except Avalon chips) with it. |

Maybe the router is only telling you the devices that requested an IP via DHCP?
Once logged into the rPi with putty, try a traceroute to some internet IP address (i.e. 74.125.224.164) and see if/where it stops.
Ok tried this. From 192.168.1.249 icmp_seq=148 Destination Host Unreachable From 192.168.1.249 icmp_seq=149 Destination Host Unreachable From 192.168.1.249 icmp_seq=150 Destination Host Unreachable Seems that I cannot send anything outbound at all. its not the 2nd half where dave says to set the gateway on the image either because I've done this before and the setup was working correctly at my workstation not too long ago. Check that it has the right gateway address. Is your router 192.168.0.1 or 192.168.1.1 or something else? My router is 192.168.0.1 and my rPi is correctly using it as its default gateway: pi@192-168-0-249:~$ route
Kernel IP routing table

okay so i took my full kit to its final home and now its acting wierd: I can access it through putty and also through the ip address to get to the bitfury web interface. I CANNOT see it on my router at all. It is not hashing at all  I figured it was an ip conflict but I can manually ip to the bitfury using my browser, although on the router interface, I do not see the device at all. While in testing mode at work I was able to see it appear as rasberrypi. Any ideas guys? Using a generic ATT 2wire wireless router. Maybe the router is only telling you the devices that requested an IP via DHCP? Once logged into the rPi with putty, try a traceroute to some internet IP address (i.e. 74.125.224.164) and see if/where it stops. |

arghhhh. these things are really sensitive.
just tried redirecting to a pool and needed a reboot. now not working at all.
any suggestions when one gets zeros across all slots?
Reboot again or restart chainminer. |

I have run zadig, installed the WinUSB driver and cgminer still doesn't show the klondikes. Running windows 8, cgminer 3.7.0 stock. Should I see something in the device manager? Perchance are you not starting with --klondike-options mhz:temp ? Does Device Manager show K16's under the "Universal Serial Bus devices" tree ? The K16s are NOT showing in device manager, correct. I ran zadig several times, and rebooted several times. No luck. Does the computer show the "new device found - installing drivers" dialog when it is correct? Try 3.7.2? Maybe full support was only very recently added. But you should see them somewhere in device manager. Did zadig see the correct number of K16 devices? Are you sure the units are actually coming on? If I power up mine with the yellow fan plugged into the board's fan pins, it doesn't init, and doesn't even spin the fan, just gets really hot. If I then unplug/replug the fan, some lights blink, windows sees a usb device plugged in, and the fan starts spinning. |

i have the entire Bank 1 at zero hashing (first 4 slots) i have 3 140mm fans and one large box fan blowing at it. have v2.2 H boards with v3 M board. doesn't matter which H boards go into those slots. any suggestions? Im going through something sort of similar however I found that it was becasue my best.cnf file was not configured properly. I'm tuning each chip to AIfDSo Bank 1 Bank 2 Bank 3 Bank 4 1: 35.137GH/s 5: 2.407GH/s 9: 32.583GH/s 13: 34.36GH/s 2: 31.768GH/s 6: 32.583GH/s 10: 0.815GH/s 14: 34.915GH/s 3: 32.175GH/s 7: 7.775GH/s 11: 36.581GH/s 15: 33.471GH/s 4: 34.915GH/s 8: 33.693GH/s 12: 35.804GH/s 16: 30.213GH/s Bank 1 Bank 2 Bank 3 Bank 4 1: 36.86GH/s 5: 34.456GH/s 9: 10.545GH/s 13: 19.936GH/s 2: 31.699GH/s 6: 18.045GH/s 10: 30.834GH/s 14: 20.129GH/s 3: 30.802GH/s 7: 34.424GH/s 11: 4.167GH/s 15: 18.045GH/s 4: 22.565GH/s 8: 20.417GH/s 12: 5.353GH/s 16: 15.353GH/s Bank 1 Bank 2 Bank 3 Bank 4 1: 30.68GH/s 5: 9.964GH/s 9: 35.004GH/s 13: 35.276GH/s 2: 32.212GH/s 6: 19.556GH/s 10: 28.576GH/s 14: 20.186GH/s 3: 32.227GH/s 7: 14.574GH/s 11: 23.293GH/s 15: 13.157GH/s 4: 13.085GH/s 8: 21.289GH/s 12: 23.221GH/s 16: 12.541GH/s This is my result from 3 tests at 5 minutes in on those settings - I saw a chron job 1-line script here that Keefe wrote that is supposed to reset stratum every 10 minutes, I want to try that script but to restart my miner every 5 minutes - seems like I'm getting solid hashrate within that 1st 5 minutes then everything runs - but as you can see from my past tests - my hashrate seems to drop every time after 5 minutes - I have 6 120 mm fans going and heatsinks so I have no idea what gives  Chainminer's autotune function doesn't kick in until 5 or 10 minutes (not sure which) after it starts. Also, the stats in the first 5 minutes aren't reliable. But if you think autotune is the problem, create /opt/bitfury/best.cnf like this and restart chainminer: 1 aIfDSo 53
2 aIfDSo 53
3 aIfDSo 53
...
256 aIfDSo 53
Note: Not sure if it matters, but those are tab chars between the columns, not spaces. Here's a simple script to easily create such a best.cnf: rm /opt/bitfury/best.cnf ; for i in {1..256} ; do echo -e "$i\taIfDSo\t53" >> /opt/bitfury/best.cnf ; done |

I have a Silverstone Strider Essential Series ST60F-ES, it has 4 PCIE connectors, if each PCI connector has only 75W and each klondike uses 60W wont I be able to only use 1 per connector rather than split each connector? I thought originally each Klondike would consume 32W, but steamboat says the F16 uses 60W. Any advice on this? Will I be able to power 8 K16's with this power supply or only 4
One of those 4 connectors is a 6+2 pin, which is designed for 150W. Assuming they use the same gauge wiring on all the cables, it should be safe to pull 150W from each 6-pin's as well (both 6 and 8 pin connectors use only 3 positive wires). Though I suppose the PSU's internal connections could be poorly designed. The PSU can do a total of 500W on the single 12V rail, so I'd say you can probably run 8 K16's without problem. Incorrect. The terminals are rated for 75W each (72Watt actual), this is why a 200W graphics card will have 2x6pin connectors for 150W plus the 75W from the PCI-e slot (~225W) and 250W cards will have 8+6pin (the 8 pins (8 and 6+2) are rated for 150W, 6 pins are only 75W (72Watt actual)). My point is that both 6-pin and 8-pin connectors use the same number of wires for the 12v line, so if they use the same quality wires for both 6-pin and 8-pin cables, then you can be sure the connector and cable can handle 150W on even the 6-pin connectors. As long as they tied all the 12v wires to the same mount point in the PSU, you're fine to pull 150W on the 6-pin's. There is only 12V line on all PCI-E 6 and 8 pin connectors, and it's not ncessarily the wire that will catch fire/melt (unless low-gauge poor quality and long length), but the connector itself  If Anyone tries to pull 150W from PCI-E 6 pin connector you MUST keep an eye on the connector temperature, preferably using a FLIR Thermal Camera. IT IS UNSAFE! You've been warned! 150W on a 6-pin connector pulls about 4A through each of the 3 positive wires/pins. 150W on a 8-pin connector pulls about 4A through each of the 3 positive wires/pins. No difference. And usually the connectors are rated for much more than 4A per pin anyway. The question is are they using the same quality connector for both the 6-pin and 8-pin connectors on the same PSU. I assume they are. |

I accidentally cleared my crontab earlier, while trying to add my own logging script. Can someone show me their crontab for a v3 rig?

Question - I am suppose to receive a second EOL board tomorrow. How do order them on the M-board.
The higher hashing one second to the end and then the lower one at the end of the line? Does it matter?
I don't want any screw ups as I'm adding two more regular h-boards on top of this.
EOL cards must be at the end of a bank, because no cards after them (even other EOL cards) will be seen. Do you have a single-bank v1 M-board, or a 4-bank v2/v3? I have one of the first ones shipped...order #12. It's V1 m-board but I thought it had four banks. Maybe not. Right now I have 4 cards and the EOL. EOL last. Pretty sure you can only use one EOL card then. Want to sell one to me? |

Probably the added airflow over the back of the regulator area.
|

|

If you donot add heatsinks to the regulator area, cards will cycle. The real point of adding heatsinks to the ASIC is to keep the regulator cool. Add sinks to the regulator and atleast the bottom 2 rows of ASICS and reduce STRESS in your life . BTW, I also did another mod, but I will not advise anyone to do that unless they know what they are doing. It's obvious if you look at my H-card very carefully. Ah, I think I see what you did. The thin wire over the fuse? Is that supposed to break if the fuse trips, so you can see that it happened? |
