Wouldn't running a miner on a VM only slow things down? Why not run a bare-metal always-free Linux miner?

Any chance of getting a kernel optimized for the 6xxx series?

for me since it costs me $0.24 to generate a bitcoin, I would guess the value of bitcoins to be $0.25 - $1 in the long term.
Is the value of a penny based on the cost to produce the penny? No. Is the value of gold based on the cost to mine the gold? No. So why do you assume the value of bitcoins will be equal to the cost to produce them? The value of bitcoins are based mainly on supply and demand. |

Well I guess my problem isn't due to running headless. When I boot with a monitor and see X (Ubuntu Desktop 10.10) up and running, I still can't aticonfig over ssh. The three lines didn't help either. |

based on the huge difficulty jump today.... I think someone has succeeded in fpga/asic bitcoin flooding  *bell ring* We have a winner! Two FPGA clusters went live. Let me toss out some rough numbers. Please correct me if I'm too far off. You have about 300 chips doing 200 MHash/s? That's 60 GHash/s you brought online? While that probably puts you in as one of the top miners, that's not a significant cause for the recent network growth. For someone without piles of existing fpgas sitting around idle: If purchased new, that's $250k in hardware costs bringing in $10k per week in bitcoin value. Half a year to pay off the initial investment (assuming price/difficulty growth remains steady). GPUs would break even in less than half that time. |

I have a much simpler setup, but I am mining headless successfully (no monitor, keyboard, or mouse plugged in at all). What I can't do is aticonfig. It complains about X not running. Do I have to hack up the /etc/init scripts to get X running without a monitor plugged in?

calculator, 7825 mhps = 24 hrs/block deepbit.net, 7825 mhps = 45 coins per day 50 * .9 = 45 Ok, if you look at it that way, it is 10%. So how about reducing the fee, say, to 5%? |

Nicely working pool. Now that you're ~700 GH/s, what do you think about dropping the huge 10% PPS fee?
it's 7% iirc deepbit.net, 8695 mhps = 50 coins/day http://www.alloscomp.com/bitcoin/calculator.php8695 mhps = 21 hours, 31 minutes = 55.77 coins/day deepbit.net fee ~11%. |

Good work on the new features. I haven't yet found a set of DiabloMiner options to beat Phoenix, but it's definitely neck-and-neck now. DiabloMiner is much easy to install and configure, so that's a big bonus.
Another donation on its way to you.

From my evaluations so far, it is the best technically 'GPU cluster in a cabinet solution' currently on the market suited to mining. They can supply an option to run 5970's.
That solution looks like a very beautiful and expensive solution. If you've seen the typical rigs around this place, price/performance is what matters. Not how cute the hardware looks. I would love to see your cost estimates on that thing. |

681 with stock everything. 830 MH/s, etc.

I didn't have the optimal Phoenix settings before. And I was rounding down. Here's an actual shot: 681.06  |
|
|
|
|
I optimized my Phoenix settings for my 6990 and installed the new 11.4 driver. At stock card settings I now get 680 MH/s, which compares very favorably with your 683 MH/s using 11.3. I have yet to try the downgrade to 11.1 trick.

Once finished I will be selling pre-installed usb flash drives for around 50BTC if that sounds reasonable ?
$150 for a $6 flash drive loaded with some open source software? No, that doesn't sound reasonable. |

I think I got 2 extra MH/s from downclocking the memory. Everything else is stock.

- 708 Mhash/sec on a Radeon HD 6990 (stock clock 830MHz: BIOS switch at position 2) -- this speed has been measured with Catalyst 11.1. Catalyst 11.2 and 11.3 contain a performance regression that downgrades the speed to 683 Mhash/s. However because aticonfig in Catalyst 11.1 does not support the HD 6990, I advise users to install Catalyst 11.3 or later, run aticonfig to generate xorg.conf, then downgrade to 11.1 for operating hdminer.
Very interesting downgrading Catalyst. Using Catalyst 11.3 and Phoenix I get 670 Mhash/s vs. your 683 Mhash/s. Sounds to me that hdminer is only 2% faster, and that the bulk of your performance improvements are in system configuration, and not miner optimizations. |

How about BFI_INT support? That sounds like the main feature that is holding DiabloMiner back performance-wise.

With Phoenix on a straight stock 6990 I get 670 mhps.
