Quote from: Bert on June 23, 2011, 03:11:05 PM In my opinion new dedicated mining rigs will rapidly become a thing of the past, if the 5% increase in hashrate a day continues. The only people who will make anything mining is people looking to buy a new computer or a new graphics card and want to reduce the cost by a bit of mining. Thought that I would share my thinking and see if anyone can point out obvious flaws. I suppose you also have to consider if the BTC -> USD exchange rate could also increase 5% a day.. There is more and more money invested in hardware these days fighting over the same 50 BTC prizes. The value of those new 100,800 BTC mined every 10 days or so may settle in close to the cost of all the electricity and hardware wasted to generate them, as long as the early adopters who got 10,000x more BTC per watt don't decide to cash out, at which time it will be mining game over.

More experienced miners have already built much better mining systems, maximizing GPU power per watt. Read the forum more...

You have to trust the person running the lottery: -If the numbers are generated before the lottery (give them out encrypted, and give the key after the round for proof), how do you know the numbers weren't given to a buddy to win, -If the numbers are generated after the lottery, how do you know the person didn't make the winning numbers so his buddy could win, -If you bet on something out of the lottery runner's control (like what will the last two digits of the hash of block 134000 be), how do you know the person running the lottery won't just take the money and run instead of paying? Anecdote of fair warning: A city boy moved to the country and bought a donkey from an old farmer for $100. The farmer agreed to deliver the mule the next day. The next day, the farmer drove up and said, "Sorry, but I have some bad news. The donkey died." "Well then, just give me my money back." "Can't do that. I went and spent it already." "Okay then. Just unload the donkey." "What ya gonna do with him?" "I'm going to raffle him off." "You can't raffle off a dead donkey!" "Sure I can. Watch me. I just won't tell anybody he's dead." A month later the farmer met up with the city boy and asked, "Whatever happened with that dead donkey?" "I raffled him off. I sold 500 hundred tickets at two dollars apiece and made a profit of $998. " "Didn't anyone complain?" "Just the guy who won. So I gave him his two dollars back."

About the only thing that goes kaboom is if you either don't cool your cpu or gpu properly (usually because the fan dies), or if you overload components like your power supply. Good power supplies shut down when overloaded, cheap ones will go until something breaks, usually a diode in the rectifier burns. Here's an example of a Thermaltake 750w power supply: http://www.hardwaresecrets.com/article/Thermaltake-TR2-RX-750-W-Power-Supply-Review/902/7. When they actually test it with 750 watts it burns out, another one did the same thing. If you explore that site, you see a lot of power supplies are blatant Chinese lies, they can't deliver the advertised power without dropping voltage, shutting down, or burning out.

Here's the current bitcoin difficulty: http://blockexplorer.com/q/getdifficulty. I reduced the formula down to: average BTC per Day = (megahashes per second / difficulty) * 1005.82838 so: 100 megahashes/s at 1379223.4296725 difficulty = ( 100 / 1379223.4296725 ) * 1005.82838 = .07292715 BTC per day Add ~1% in transaction fee wins (if paid by pool), subtract downtime, connectivity issues, and rejected block overhead, and subtract pool fees. If you join a large pool that solves several blocks a day your results will be very close to this. If you are solo mining with a GPU, it is more like a lottery - although stats say it would average eight months to win 50 BTC at current difficulty with a good ATI GPU, you might win it tomorrow or you might never win in your lifetime. Difficulty increases are calculated every 2016 blocks based on the past performance, which are every two weeks if the bitcoin network hashrate is constant. Since the network keeps on increasing it's computing power, the recalculation happens more often than that.

ATI Radeon HD 58xx series are better than 6xxx series at mhash per cost of card, that's why they are sold out everywhere. Being able to ever break even on new card by mining is very iffy now. If you are going to be gaming and just hobby mining, you should get whatever card suits your gaming needs.

Quote from: Slümdawg on June 23, 2011, 06:16:13 PM Maybe someone can answer my question here. Been lurking for a little while and got into Bitcoins over the last week. I have a Sapphire 5870 Eyefinity 6 2GB, and so far while mining with slushs pool w/phoenix Im doing a respectable 410-420 MHash. However I've been pretty unsuccessful getting the memory clock down below 1200Mhz. AMD's GPU Clock tool doesn't detect any AMD/ATi hardware whenever I fire it up and this is what most 5870 users have been doing. Currently I have CCC 11.6 and the Sapphire TRIXX utility that I've been using to change clocks/volts, but memory wont go below 1200. Most users are using memory clocks aroun 300Mhz!! Can I get in on that?! http://forum.bitcoin.org/index.php?topic=7790.0 This is the particular thread I'd like to get into lol. Also I have general questions about phoenix miner, more specifically why it accepts many connections. What are these? They seem to echo the same number of connections displayed in bitcoin.exe while its running in the background. EDIT: After some time it seems that I will accept WAY more than the specified connections in bitcoin.exe. Still what are these for? Finally, solo mining for phoenix has got me stumped as well... My bat file currently looks like this... Quote start /D"C:\Program Files (x86)\Bitcoin\phoenix" phoenix -v -u http://bitcoin.xxxxxxxxxxxx:xxxxxxxxxxx@localhost:8332/ -k phatk device=0 WORKSIZE=128 VECTORS BFI_INT AGGRESSION=13 The bat file for the phoenix miner in slushs pool has the identical config other than the url/localhost and username/pass stuff. Does this look correct? I don't have the same card, but Sapphire 5830s. Trixx works just fine on XP and Win7. Some have said that on their Non-Sapphire cards that first setting to 600, then 300 works. In Trixx I simply press "reset" and "apply" to reset to stock. Then set all sliders to what you want by typing or using +/- (5830=1000/350/no overvolt), and press "apply". Also, leave trixx running minimized, if you customize the fan curve the software needs to be running to use it. I would completely uninstall trixx, uninstall every ATI item in the control panel->programs and features until nothing is listed, also remove any other old video drivers like nvidia, go to device manager and uninstall the video card (make sure you choose "remove driver" unless it is already VGA), and restart. Let the video card be detected again by windows, restart if prompted. Then install the 11.4 individual driver-only/2.4 (with OpenCL) package off the ATI site and restart. Then install newest trixx. Set only the memory to 400 and press apply. If it doesn't work, call tech support. Solo mining is a lottery, it would be three months on average for you to win 50BTC, but with the difficulty ramping up, you'll probably have a 50% chance of solving a block in a year.

This is an odd policy - I ought to start a thread "introduce yourself here five times". I also noted there is no email verification on the site. Alternately, send .001BTC low priority to the forum to be a full member (i.e. If you can get a bitfaucet payment and send it to the forum, you're not a retard), but that's probably not something easy to add to simple machines forum.
