DEVICE=ID - Sets the OpenCL device to use. This isn't needed if you only have a single device.
So this miner requires you to run multiple instances for multi-gpu configurations? Why not just use all available devices by default? |

So 1 Gh/s generates 326.7 BTC at today's difficulty. Those 2 are offering 326.7 BTC for the cost of about 280 BTC. Nice deals!
331 BTC on the other hand sounds way too high. You should update the FAQ in the first post. You no longer are offering a cheaper deal.
Yes, I do offer the cheaper deal ("my price will be an average of 245 BTC per Ghash/s/month over the next 3 months" -- a conservative estimate.) That is your estimate of what may happen. That is not, today, a cheaper deal. As I said, both BitcoinRigs and vladimir lock you in for 3-4 months (you will generate much fewer than 326.7 BTC/month by then.)
Edit: if you prefer their kind of flat pricing over 3-4 months, I can match that! 1 Ghash/s for 4 months at a price of 270 BTC/month. What do you think?
270? What happened to 245? |

I am correct:
* BitcoinRigs: 1337 (USD for 3 months for 1 Gh/s) / 3 (months) / 1.60 (USD/BTC) = 278 BTC
* vladimir: 4444 (GBP for 4 months for 4 Gh/s) / 4 (months) / 4 (Gh/s) * 1.65 (USD/GBP) / 1.60 (USD/BTC) = 286 BTC
(1.60 USD per BTC was the average these last few days - the run up to 1.90 USD is unlikely to last.)
Ah, I misunderstood. So 1 Gh/s generates 326.7 BTC at today's difficulty. Those 2 are offering 326.7 BTC for the cost of about 280 BTC. Nice deals! 331 BTC on the other hand sounds way too high. You should update the FAQ in the first post. You no longer are offering a cheaper deal. |

Edit: the trial was a success. I will continue this offer. I operate a 15 Ghash/s mining cluster, and offer selling mining capacity at a price of 331 BTC per Ghash/s per month. - BitcoinRigs who sells 1 Ghash/s/month for 278 BTC (1337 USD for 1 Ghash/s for 3 months, 1.60 USD/BTC)
- vladimir who sells 1 Ghash/s/month for 286 BTC (4444 GBP for 4 Ghash/s for 4 months, 1.65 USD/GBP, 1.60 USD/BTC)
I think you need to look at your calculations again. Your prices for your competitors USD/BTC are incorrect. |

please link lower prices.
bitcoinrigs.com's "Professional Rig": $1 more expensive than your cheapest model (which seems equivalent - both use one 6990). However... their cheapest model is only $899. Took me twenty seconds in Google. I used "mining rig site:bitcoin.org" to search, and clicked on the first link. bitcoinrigs.com model is far superior, with a larger power supply and room for a third video card. That alone is worth far more than "free shipping". Or compare their dual 5870 to your single 6990. The dual 5870 will hash faster and is $600 cheaper! |

Thank you. Adding "-v -w 128" definitely made a difference. I just have a single 6990, and a single 6990 has two GPUs, so I don't think I need to do anything with crossfire.
Can you get over 550 mhps? |

Linux is not an option for a 6990 rig. ATI has not released the Linux drivers yet.
Pretty damn important piece of information to know. As stated numerous times, this is untrue. The 6990 is fully supported under Linux by the Catalyst 11.3 driver. I am mining with it! The confusion comes from AMD's website that only lists Windows 7 drivers when selecting "HD 6990". Select "HD 6xxx" instead. So if I go to http://support.amd.com/us/gpudownload/Pages/index.aspx and select HD 6990 I see only Windows drivers. That's not fully supported, now is it? There are significant problems with the 11.3 driver, especially relating to OpenCL. So unless you plan on Open Sourcing your CAL miner, stop telling people that 11.3 is "fully supported". |

Nice idea. I hope someone posts back with their results.

Is bitcoin legal to have and use? Of course it is legal. Bitcoin is hardly the only virtual currency around. |
|
|

That's just wrong... as I type this, I see the command prompt windows telling me that my 6990 is still hashing at 330mh/s per core.
Details? Miner, OS, Driver versions, etc. |

The 11.4b linux driver seems not ready for prime time yet, i only get 250-301(averaging ~220) mhps per gpu on 6990, my setting is -v -f 0 -w 128.
Yes, very disappointing. I get about 275 per gpu with both 11.3 and 11.4b on my 6990s using DiabloMiner, all stock clocks/etc. I hoping for something more like 350. |

I'm running a 6990 + 2 6950(unlocked) in Ubuntu 10.04 just fine with 11.3....
What's the hashrate on the 6990, and which miner? |
|
|
|
Not true. I mine happily with multiple 6990s with the catalyst 11.4 driver on Linux. To my surprise, even the older 11.3 works, if you write the xorg.conf manually. That said I do use a custom CAL miner, as opposed to OpenCL, so perhaps the problems preventing you guys from using the 6990 only affect OpenCL miners. What catalyst 11.4 Linux driver? |
|
|
|
Are you absolutely sure you're using SDK 2.4?
I am now. I installed dual 6990s and did a fresh install of Win7, Catalyst 11.4, Stream 2.4, and latest DiabloMiner with '-f 1'. 4 Caymans are found but hashrate is poking along at under 700 mhps. |
|
|
|
|
Anybody with Win7 and a 6990 running DiabloMiner? I installed Catalyst 11.4, and while DiabloMiner runs, the GPU activity level barely gets above 80%, and thus my hashrate is poor.

I threw Win7/32bit on my box and it is slow as a dog. I hope 64bit is better.

Price just jumped $.10. I wonder who is buying...

On average there are 6 blocks an hour which comes to (6*24*50) = 7200/day. So you are looking at <28 days worth, not 2 years. Even this much will move the market substantially. What do you think happens if you try to buy 5% of all dollars? Or 5% of all gold? Obviously disruption. You can't even know how many coins you will want or be able to afford until you start buying.
Agreed. Buying that many coins on the open market is going to shoot the price straight through the roof. I say go for it!!! In two months when the price hits $5, I'll cash out, then a month later the price will settle back down to $1 and I'll buy back all my coins for a huge profit. Just one hangup ... Doesn't mtgox have a $1000/day withdrawal limit? I don't see how you could get that many coins out of mtgox in 2-4 months. |

Since I'm currently measuring 21.471 Mhash/s with my Cell implementation, I guess you could work backwards and calculate 76800M / 21.471 Mhash/s = ~ 3577ops/hash.
However, I think you're right that it is still outclassed by a midrange GPU.
Outclassed by a factor of 10. |
