I should solve a block in 2.5 months... not so bad as long as I know it's working... amazing there is no clear way of making sure, like a green light in the GUI!? Also if there was a C/C++ or Java implementation of p2pool I would definitely use that!
The problem with that is the difficulty has a tendency to rise over time so by the time 2.5 months is up, the estimate may be 5 months... it really is a lousy idea solo mining with less than 100GH. |

12.4 driver has a bug that enables ULPS on the 2nd+ GPUs. Downgrade drivers or search google for "disable ULPS". Some regedit shit on windows will fix it.

I'm wondering if pools will be able to keep up with a sudden spike in the network speed
I doubt many pools will be able to handle 50 TH/s or 100 TH/s
Will mean a lot of additional hardware expenses on their side, without any additional income for them.... Back to solomining ?
No, there's an easy fix already for pools - shares at higher difficulty. The difficulty 1 share acceptance just needs to be scaled to the network size. Of course your mining software needs to support this, and cgminer is already ready for it  |

I'm quite sure the longpoll delays are affecting not only mtred but other pools as well, and the delay seems to correlate with the number of transactions on the network. The fact that deepbit, which limits the number of transactions, is not getting delayed LPs supports this theory. Blame satoshidice.

Just wait that AMD will add that "usb warmer" chip into newest GPUs  Not really, as AMD really don't care about mining since it's only a tiny proportion of their sales. If they cared they could produce a product that would blow everyone out of the water, as could intel or nvidia. Bitcoin mining doesn't even register on their radar. |

3) BitForce SC Mini Rig: a case & rack mount server providing 1 TH/s, priced at $29,899 If BFL made just one of these, they could earn $40k per week as 1/15th of the current network, so why sell them? Something's not right with these equations unless the profit margins are ridiculously large... |

32bit windows CANNOT run more than 4 cards. Install 64bit.
Where exactly is the restriction? In number of phycical cards or number of chips? I understand that it's imposible to fit 5 5830s in W7 32 bit, but is it possible to fit there for example three 5970s? It's an AMD driver limitation. |

[ copy of email sent to support@enterpoint.co.uk ] Dear Enterpoint It has come to my attention that you are distributing a modified version of the cgminer code in binary only form from your support website here: http://www.enterpoint.co.uk/cairnsmore/cgminer_windows.zipAs the maintainer of cgminer, I am pointing out to you that the codebase you are building on is licensed GNU Public License version 3.0. The terms of said license agreement are here: https://raw.github.com/ckolivas/cgminer/master/COPYINGwhich can also be found here: http://www.gnu.org/licenses/gpl.htmlIn violation of this license, you are releasing binary-only modified versions of cgminer which also include a binary only blob to be used with your hardware, as well as completely removing any reference to the original license agreement. I am going to assume this is a simple misunderstanding of the terms and conditions of the licensing agreement. I hereby kindly request you stop distributing cgminer in this illegal manner. You are obliged to provide links to the source code for all modifications done to our code and the source code for the binary firmware you include with this archive, as well as the original licensing agreement, should you wish to further distribute this code. If you wish to provide support for your hardware with cgminer, there are 2 broad options: 1. Provide modifications to cgminer code directly to the maintainer (i.e. myself) to be included in the master codebase upstream, add binary blobs to the code upstream and provide a URL link to where the original source for the binary firmware may be found. This will be the easiest to maintain long term and benefits everyone the most. 2. Maintain a fork of cgminer with your modifications to the source and the source for all dependent binary firmwares freely available for download. I hope cgminer support for your products can continue to be provided in the appropriate manner for your company and client's benefit. Regards, Con Kolivas |

Today i update the driver to 12.6 beta, remove the includet sdk and install the 2.1 sdk.
Now the prob is, that cgminer seem to work with ~350mh/s, but there are no shares at all?!?
wtf...
2.1 sdk does NOT work with the newer 12.x drivers at all. They are simply incompatible I'm afraid. Um. I use 12.1 driver and my 2.1 SDK works just fine. Try breaking it with 12.4 I'd rather not fix what isn't broken, unless you'd like to pay for my mining downtime. Duh as if I expect you to... I was just pointing out it's newer 12.x drivers that are problematic, as I had said in my post. |

What timezone are you, and what port ip is pool0 and 1?
I'm in UTC+10. Pool 0 is a port 8332 pool with a ping time of 350ms, pool 1 is port 8337 mtred with a ping time of 250ms. Note my rejects are in the order of 2% now with mtred. edit: Those rejects are so high I had to drop my donation to make it worth mining here... |

Lol nah  |

BTW any word on using more than 32 pools??
I wasn't serious... but anything can be done. You really want this? |

There was also nothing accepted for 20 seconds which at a utility of 39 shares/minute there should be ~13 shares. The 15 rejected shares works out to ~23 seconds of lost work. |

bitlane acknowledged it might just well be 10 weeks, but the point of his post was how long he has paid for an investment that is not mining. That makes their return on investment time longer much worse. * ckolivas hugs his 7970s |

Bus error
It works great until a share is found, then it dies an immediate and horrible death  I was hoping the code for testing if it was a block solve was fixed for openwrt so I removed the commenting out of that test. I guess it was premature and that bug still exists. This is the commit responsible in git: dbe9056df4db4007524af9569edc28c92827b3c4 |

it is not downloaded automatically
They're automatically generated when you run cgminer so you don't need to download them. However if you are after binaries from different SDK versions to what you have installed, you're out of luck as I stopped collecting them because it was getting too much effort to keep them all. |

I seem to be getting a heck of a lot more rejects across longpolls lately. There's a deathly pause where no shares are being accepted, then the longpoll hits and a ton of rejects are returned along with it. eg: [2012-06-15 19:56:56] Accepted 474d3cb6.ba57e09a GPU 2 pool 1

Does CGMINER support multiple backup/fallback pools?
I've noticed that a number of pools will be down or lagging at any given time, so I'm looking to set up 3-5 backup pools to mitigate all this downtime I'm seeing on my miners. Been using GUIminer up to now, but the 1 backup server option still leaves me running idle every now and then.
cgminer supports no more than 32 pools I'm afraid. I can remove that limit in the next version if it's desired... |
