so how do I tell where ICA 24 is located among my hubs? is there a way in cgminer to force the green light on the USB Miner to flicker very fast to help locate a particular USB Miner? kind of like on some hard drives in raid array you have an option to "identify" a drive by turning on a flashing light or something... if this feature does not exist, i'd like to request it. should it be added to ICA, AVL and BFL devices?  |

It is a common myth that Bitcoin is ruled by a majority of miners. This is not true. Bitcoin miners "vote" on the ordering of transactions, but that's all they do. They can't vote to change the network rules.

Hi, does anybody can help me? I'm using Ubuntu 12.04 64bit and the latest cgminer 3.2.1 I have 6 7950 GPU, installed drivers properly and all the needed sdk tools as described on many tutorials. Ubuntu detects all 6 card with no problem. I tried many many combinations of scripts to get good hash rates but failed all the time. I saw all the time that 1 GPU temp goes high - working on 80C, but the other 5 cards are on ambient temps. Max hash rate is 100mh/s per GPU what I able to make. The script is: ./cgminer -o http://pool.50btc.com:8332 -u XXX -p XXX -I 10 --gpu-reorder --auto-fan -w 256 -g 1 Posted a screenshot maybe will help http://s24.postimg.org/3llk0yhqd/low_hash.jpgThank you in advance |

I don't think you need to specify a work size with those GPU's, not sure though since I don't have those. Why are you limiting your GPU's to one thread? I would remove both of these settings. Sam |
A: Because it messes up the order in which people normally read text.
Q: Why is top-posting such a bad thing?
A: Top-posting.

What does "cgminer-nogpu" -n say? I use 3.2.1 and it tells me what bus number and device number each one is so I can, with some trial and error, which one is which. I agree your suggestion would make things easier especially with the number of devices you have. I would hate to map all of those serial ports like you are with 3.1.x. I would recommend going to 3.2.1, it really is much easier. Sam |

Sam I tried it without them, same story. It's like GPU's not working on their full power (this config worked in windows, hardware is ok, linux is more stable). I don't know is there some settings how to configure GPU usage. |

I don't know is there some settings how to configure GPU usage. This looks familiar. I think someone else had a similar problem. Anyway GPU usage is affected my intensity and engine clocks. What Catalyst and SDK are you using? |

I tried to set intensity from 10 to 18, all the same, defined GPU and MEM clock manually, same issue. Trying different combinations for days but again the same. I have [fglrx] module loaded - fglrx 9.0.2 [Sep 20 2012] with 6 minors AMD Driver and ATI OpenCL Drivers 2.8 and ADL SDK 5.0 It is promising that I'm not alone with this problem, tried to search for it but just can't define correctly the search  |

AMD Driver and ATI OpenCL Drivers 2.8 and ADL SDK 5
Hmm, I was expecting something like Catalyst 12.8 and OpenCL 2.6 or something along those lines. From the FAQ Q: Which AMD SDK is the best for cgminer? A: At the moment, versions 2.4 and 2.5 work the best for R5xxx and R6xxx GPUS. SDK 2.6 or 2.7 works best for R7xxx. SDK 2.8 is known to have many problems. If you are need to use the 2.6+ SDK or R7xxx or later, the phatk kernel will perform poorly, while the diablo or my custom modified poclbm kernel are optimised for it. Q: Which AMD driver is the best? A: Unfortunately AMD has a history of having quite a few releases with issues when it comes to mining, either in terms of breaking mining, increasing CPU usage or very low hashrates. Only experimentation can tell you for sure, but some good releases were 11.6, 11.12, 12.4 and 12.8. Note that older cards may not work with the newer drivers. |

That was my last option to reinstall all the drivers/sdk. Thanks for helping, I will post here results, maybe more come with similar problem. |

I have cgminer 3.1.1 and five USB ASICs on an Anker USB 3.0 hub and windows 8. If I try to run them in one instance of cgminer, only the first one is active and the rest show up as off. Strange thing is, I had three working just fine in one instance and it was only after I added the COM settings for the two new ones that it stopped working. If I run an independent instance for each miner, they all work. |

That was my last option to reinstall all the drivers/sdk. Thanks for helping, I will post here results, maybe more come with similar problem. I noticed a big difference switching to the poclbm kernel. It's not used by default. I'm running two 7850s with Catalyst 13.4 and either SDK 2.6 or 2.7, (I can't remember which). One of my cards always runs hotter than the other. Initially it was so much hotter that CGMiner would throttle back the clock from 1050 to 860, but now they're running pretty evenly matched at full speed. (This is all on 3.1.1 by the way, there's not much if any GPU improvements in 3.2.1 from what I understand). |

I assume you mean your GPU fans. There were absolutely no GPU changes going from 3.2.0 to 3.2.1 so you have changed something when upgrading cgminer, likely the driver... |

OpenCL 1.1 AMD-APP (831.4) FULL_PROFILE 8.15.10.2696 (3-19-2012) - GL:ig4icd64.dll absolutely nothing changed... just unpack new cgminer on desktop, where all old versions located, copy config files and shortcut to new cgminer directory and do corresponding shortcut changes |

***Insert standard "I tried to search" disclaimer***
I am getting an error with cgminer 3.2.1; windows7 x64; BFL Jalapeno: "Waiting for USB hotplug devices or press q to quit" I have installed the winUSB drivers. The Jalapeno works fine with BFGminer and the other drivers. Does anyone have any suggestions, as I would prefer to use cgminer?
