I've been using the 'Bitcoin Address and Wallet Import' area to just dump public addresses for it to import. It works like 90% of the time- the other 10% it seems to just not process the job, so it just sits there doing nothing... forcing me to delete and re-create the job, or in the cases where the public address contains more than 50 transactions, the job just processes the latest 50 and just stops. I end up with partially imported transactions, so I have a blockchain explorer window open side by side to verify the transaction number I'm expecting and compare it directly to how many were imported by CoinTracking.
Has anyone else run into this? Should I just leave the jobs that processed the 50 out of 50+ transactions and it will process the rest? Or is deleting the job (and partially imported transactions) the only way around this?

Alrighty, well yours is the new version without a 0.9V LDO. The two resistors right above it (331 and 471) are a voltage divider that gets your 0.9V line. I don't know why you'd see 0.48V on 0.9V (after testing some 400 current-version sticks I've never seen that error) but it could be a problem there. If those resistors are seated correctly and doing their job, it must be something broken inside the ASIC.
Thanks for looking into it and responding quickly. I checked the 0.9V connection on the other 3 sticks and they show between 0.90-0.93 V, so this one does seem to be the odd stick out. I'll PM you for further steps to take for repair/replacement. |

So your 0.9V is reading at 0.5V? That's very not right. Poke around on the legs of the SOT23 LDOs over on the side there and see what you get.
I Google'd what a SOT23 LDO was and there was only one on the side that I saw. Let me know if I measured the wrong points or if this is completely off. These were my readings:  |

Not underneath the heatsink, below the heatsink Slightly closer to the USB connector than the edge of the heatsink. The reset testpad is the pad on the back labeled "reset".
A visual inspection doesn't show any clearly damaged areas, but I've included more pictures just in case. https://imgur.com/a/tOHbYI measured the voltage using the reset testpad and these were my readings: VCORE: 0.55 V 1V8: 1.80 V 0V9: 0.48 V RESET: 1.61 V |

Hello! I received my 4 units today from the latest batch and just got set up following the gekkoscience.com/misc/cgminer-gekko-win32.zip provided in the OP. Settings are just running at the default 150MHz clockspeed and balancing between two pools. I'm running into an issue where one of the Compacs simply refuses to start mining- the green light comes on, I'm able to see it in Windows Device Manager and install the drivers using the zadig tool, but that's it. I've tried connecting via USB ports directly on three different machines (Win10, Windows Server 2012 R2, Raspberry Pi B with Minera + Compac mod) and two different powered USB 2.0 hubs with no luck. The other three Compac units work fine with any combination of machines/hubs, so I am thinking it may be something with this one Compac unit. I noticed that the white light also doesn't come on with this unit anymore, although I'm pretty sure it did the first one or two times when I first plugged it in. I have one of those USB Charger Doctor gadgets (in-line voltage and current meter), and I notice on the stubborn Compac that it reads 5.04-5.05V/0.06A upon being plugged in and idle/not mining. The other units that are working fine read 4.96-4.99V/0.19-0.22A when plugged in and are idle/not mining. This is as far as I can get in cgminer:  Any suggestions? |

I have done a fresh install of ubuntu 14.04 server. Can anyone has any idea why in my ip adress appear only apache page and not that i have setup? http://192.3.52.176/For some reason they changed the directory to /var/www/html instead of /var/www I am doing this from memory right now so it might not be 100% correct, but you need to modify the path. Something like this: sudo vim /etc/apache2/sites-available/000-default Change DocumentRoot I think it is from /var/www/html to /var/www Then restart apache sudo service apache2 restart D'oh! This was what I was missing. I was able to get my node up and running. Thanks!! Edit: Node is at http://168.235.152.55/ |

Look at cex.io right now. You can buy 1 GH/s for 0.2125 BTC, but 1 GH/s will never mine more than 0.1850 BTC (assuming an average difficulty increase of 20%).
Even assuming that cex.io is legitimate, why would anyone pay 0.2125 BTC to mine 0.1850 BTC?
I don't think this business model will ever work simply because there is no reason for cex.io to mine bitcoins for someone else when they could make more money by mining for themselves.
I've also done some math when first saw this site, it doesn't seem to be a good deal... There is a quick way to estimate what a hash rate is worth: Use this formula: VALUE = H * 7040691 / D / R, where H = your hash rate in GH/s D = current difficulty R = average increase in difficulty each period for the next several months For the last 8 months, R has been about 0.30 (30%), but that can't continue much longer. I predict R to be about 0.20 (20%) over the next several months. That's how I get a value of 0.185 BTC per GH/s. Others believe it will be much higher and miners seem to think it will be a little lower. This calculation also doesn't include fees and expenses. Cool, thanks for the explanation and calculation. I may have missed this, but where does 7040691 come from? |

would someone post some figures from a 10gh blade? how many day currently is it taking 10ghs to make one coin?
10.1 gh for 10 days at a diff of 87 mill will make .59 coins 10.1 gh for 10 days at a diff of 113 mill will make .45 coins 10.1 gh for 10 days at a diff of 147 mill will make .34 coins so this is a 30 day projection of coins earned for the next 30 days at 30% diff jumps. sooner or later the 30% jumps will level off but as to when that happens  Think you're off by a decimal point there. It'd be 0.059 BTC, 0.045, 0.034, etc. |
