I just got mine. 2 red and 2 black.
Had them mining in under 2 minutes.
Thank you for your amazing customer service.
Question: Is it better to set up a worker for each one of them or is it ok to run them all under one worker?
I've got five per worker. I have 6 Erupters at the moment and have 2 per worker per pool in 3 different CGMiner sessions. Using the --usb ICA:2 argument in CGMiner 3.3.1 and has been working great. But if your only mining on one pool at a time just run them all in one instance with one worker. Just make sure you have failover pools setup. Sam |

Where do you get those little heat sinks?
Now that I'm ready to get some I can't find a link to order them from.
Thanks,
Sam

5830 for 2 years and 2 months.
5770 2 years and 1 month.
I just retired them both last month after getting Block Erupters. Both GPU's are still functional.

I strongly recommend BFGMINER for USB Block Erupters.
BFGMiner may well be just fine. But I cannot believe it is easier nor more reliable than CGMiner. The install was the easiest miner setup I have ever done, with any mining program including Ufasoft. I am running 3 instances to three pools 2 Erupters each. Maybe since I don't have a high number of devices I'm not seeing issues others may be having?? Mapping Erupters as serial ports has to be problematic as the serial port mappings will change at Windoze' whim on a reboot which would cause major problems with multiple instances of a miner. Win7 32 bit CGMiner 3.3.1 2 Rosewill USB 2.0 7 port hubs. Sam The problem is the -newest- cgminer requires more than just mapping them to COM ports. It uses WinUSB on top of the other tool that maps them. As a result it's fully hotpluggable, but adds an extra hoop and sometimes requires you to run an extra tool to re-assign WinUSB when you change ports/add more units. Meanwhile, bfgminer only uses the software that makes them show up as COM ports, and you run '-S all' to have it scan/recognize all of them at once. Older cgminer verisons work the same as bfgminer as far as I'm aware, it's only the newest version that added extra steps (newest cgminer does not have -S at all). My experience with installing USB serial drivers and having them stay mapped to a particular comm port is more like hoops with flames. Whereas using the Zadig utility is a one time event you never have to repeat again. I just don't see the validity in the comparison. I'm not trying to be difficult, nor say anything disparaging about BFGMiner, but CGMiner setup is not as problematic as many have MADE it out to be. One caveat in my experience, the Block Erupters are my first USB mining devices so I had no baggage from previous installs/configurations. Sam |

This would open up some nice dynamic configuration options  Such as, making it easier to control botnets? |

Does a namecoin status in payments and PPLNS Statis work or is it just me?
NMC doesn't show up anywhere outside of the dash board at this time. I don't see where, could you point me the exact place on dashboard? I have a NMC address set up in settings Enable "Show Namecoin Summary" in the account settings |

I didn't try reinstalling zadig because the XP version doesn't seem to have the libusb 1.0 version that is recommended in the readme.
Worked fine on my XP SP3 |

A Star topology offers a more direct route so that would be my first choice pending testing.
I'm using 7 port Rosewill hubs which have 5 Powered ports and 2 unpowered which, I believe, have their own separate controller for the purpose of daisy chaining, or so I thought. Are all 7 of the Dlink ports in Alexrossi's diagram powered? Sam |

Is possibly a thing like this? Thanks in advance for all the replies  Well your diagram poses a new question with me. Is it better to configure the USB Hubs in a Star Topology as you are doing or to Daisy Chain them in a type of Bus Topology? I am connecting mine in a Bus Topology and never really put much thought into doing a Star. Sam |

By the way, currently I have 4670 GPU, run PCI-E 1.1 x16 (32MH/s with 750MHz > 800MHz clock using cgminer).
So, if I move GPU to motherboard that capable PCI-E 2.0 x16, dose Hash rate will increase? i think not
I was getting 35Mhs on my AGP 4670. So I would expect you should be getting higher than that already. But no changing the slot/MB won't help. |

The order for additional units was placed last night with friedcat. They should arrive on Friday, unless the 4th of July holiday adds *2* days instead of 1 to the delivery, or a random holdup occurs. The new batch will cover all current backorders, and will hopefully cover all backordered units that are ordered up until Friday. If the backorder queue starts getting "dangerously close" to the number of new units ordered, I will order even more to compensate.
My goal is to eventually have a reasonable (100-200 units) in on-hand inventory at any given time. The only thing preventing that right now is it's hard to judge what the residual demand will be once the first feeding frenzy is over.
Canary sold over 1000 in group buy #7 alone. Could be a while before the frenzy is over. M I'd speculate around end of August to the beginning of September. |

Yeah, that will explain everything. This pool could be 10x times bigger. But, NMC, why bother... no?
Good luck guys.
NMC is a waste of time and effort. It's an abandoned project that has failed and was never meant to be a currency. It caused problems for EVERY pool that has ever implemented Merged Mining. And it is worthless. But hey, besides that it's just great. Sam BTC Guild (the largest and most advanced pool in the world) added merged mining for NMC just a couple of weeks ago. There was much rejoicing. So much for "abandoned." The DotBit project has resumed development? NMC has the third highest cryptocoin market cap behind LTC, a position it has held for many months. So much for "worthless" and "failed."
The last time I looked it was over 250 NMC to get one BTC. So if NMC is the 3rd most valuable alt coin then the others must be really worthless and a waste of time. But keep repeating your baseless, demonstrably false assertions ad nauseum. You might get lucky someday and find them to be true!  Until then, we'll be amused by your embarrassing confusion between actual reality and wishful thinking. My "baseless, demonstrably false assertions" are mostly opinions I hold and may not be completely accurate in their entirety, as I am not proponent of ANY alt coin. But you have failed to demonstrably prove that the DotBit distributed DNS system is still being developed. And nobody has made an argument that Merged Mining was good for the DotBit project, I think Merged Mining destroyed what may have been a worthwhile project, but again that is opinion on my part.

But it sucks to wait, doesn't it?
It's not a big deal for me at this time. But at some point it will be. I still have not seen an explanation why an artificial soft limit was established in the first place. |

"diakgcn" is the Diablo GCN kernel, it is designed for GPUs built on GCN technology (Radeon HD7000 serries)
CG miner auto-selects the best kernel for your hardware and rarely gets it wrong so just use the default kernel and you'll be fine.
Ah, OK. At one time there was a diagnostic kernel probably started with diag* instead of diak*. Thanks for the correction. Sam |

Folks, if you could say a prayer for my uncle
Prayers ascending. |

both GPU, run OpenCL benchmark, no problem. Latest test:  I read Diablo Readme for GPU vector size, and diablo return opencl worksize 256, and apply it here. I try use other kernel, seem mining no respond at all, like null? this one on Catalyst 13.4, OpenCL 1.2 Uh, I think the "-k diakgcn" is a diagnostic kernel that doesn't actually submit any shares. try using "-k phatk -v 2 -w 256" |

Zanatos666 ask report here, I have 2 GPU with different desktop platform. Radeon HD6870 GV-R685OC-1GD Radeon HD5770 GV-R577SO-1GDBoth GPU are GIGABYTE Super Overclock SeriesBoth GPU can't use for mining, CGMinier give crash during starting application, same with poclbm. These GPU unsupported? I have used a 5770 with no issue. And others are using 5770's and 6870's with no issues. I would recommend reading the readme and pay special attention to the Q & A on the catalyst and SDK versions to verify that you have the correct versions for mining. This is a helpful link, I think https://en.bitcoin.it/wiki/Mining_hardware_comparisonSam I reformat and downgrade Catalyst and use AMD Stream. still no luck. What versions of Catalyst and OpenCL SDK? What coin are you trying to mine? Can you capture the error's and post them? Do the GPU's work with games or 3d rendering test's such as those with GPU Caps viewer? |
