I have a double 6870 box, though it's also for gaming. I get 580Mhash @ 430 W. If you want to "just get by" with a rig, it would be cheaper -- but if you decide to expand, it will cost more, since instead of just adding cards you'd have to add a new everything. Regardless: Mobo: http://www.newegg.com/Product/Product.aspx?Item=N82E168131305912 slots, and cheap. CPU: http://www.newegg.com/Product/Product.aspx?Item=N82E16819103888Single core, but cheap as they come. PSU: http://www.newegg.com/Product/Product.aspx?Item=N82E16817139028Reputable brand, cheap, and enough wattage to cover your 6870s and fans (my box is running 2 6870s, 4 130CFM fans, 2 HDDs on a 600W PSU). Ram: http://www.newegg.com/Product/Product.aspx?Item=N82E16820139924Same as before. Total is just over $200 before rebates. You wont have any room for upgrades, though. |

That motherboard only works with socket FM1 APUs -- the Sempron you listed wouldn't work. |

But now I can't find Terry's posts by looking for the red x's. On a more serious note, glad this worked out.

I took quite a few quizzes, and a couple of the history questions were incorrect -- I did check them though.

I'd recommend, as a "backbone" for a GPU rig:
MSI GD-70 AM3 Motherboard
Athlon CPU
2GB DDR3
1200W Seasonic PSU
Flash drive to run the OS off of.
Beyond that, all you need is the cards -- 6870s are pretty affordable now, get ~300Mhash, and would have factory warranties. You could easily put for of them in that setup, and it would be just about USD $1200 to do so (before rebates). So about $1/mhash for all new equipment. Obviously if you could get some used 58xx cards, you'd be able to bump that number up.
It really isn't too difficult to put together a computer -- these days things can usually connect one way, and they're color coded to boot. Otherwise you'd have to have someone like Shakaru throw the rig together for you.

Standardized chipset mounting holes will allow for water cooling too. @Fizzisist:
This is kind of a minor thing, but would it be possible to move the USB connector to the same side as the barrel / molex connector? That would make it much easier for enclosure /air flow designs.
Might make it easier to develop some sort of backplane too, so you could just plug the board into a "dock." I think I'm going to have to save up my BTC to get one of these. |

Have you tried using CGMiner with dynamic efficiency? I'm not sure why the 7ks would take a larger hit than the 6ks, unless it has to do with how GCN splits up work.

As to "rich people wear casual clothing" because "they don't care what you think," that, in my experience is a lie. Wearing nice clothes has nothing to do with self image, and everything to do with respect for others -- and successful people tend to have plenty of respect for their friends, clients, customers, and even the people they purchase from. No one wants to see you in sweat pants, so please respect others enough to put some effort into your wardrobe. Note that I said effort, not money -- I frequently get dress shirts/pants brand new for $10 or so, cheaper if they have my size at a thrift store. Not to mention dressing nicer helps you get paid more, get better service, etc.
Of course if you meant "casual" as it's supposed to be used -- that is collared, button down shirt w/o tie, pair of khakis (NOT cargos), loafers, belt -- then yes, I agree.
At the end of the day "not caring what others think" looks like "don't respect you enough to care" and that attitude makes it difficult to be successful.

I honestly wouldn't recommend JavaScript as a first programming language -- it's got a lot of things that differ greatly from C/Java, which are much more common (untyped variables, for one). Obviously if you need JavaScript for a project, then yeah, you don't really have a choice. If you just want to get a good foundation for programming, C++ or Java would be better, and would have better resources available (college textbooks especially). If you really must use JavaScript, the reference I used to get started is http://www.cs.brown.edu/courses/bridge/1998/res/javascript/javascript-tutorial.html. Lots of universities computer science depts. have useful tutorials online -- some even have lab assignments you can work through. |

Also, because people will probably ask: a picture of the watch, with a note that has your username and the date written on it.

Actually, I'd say that writing a faster miner and keeping it for your own use is adding to the security of the network, PROVIDED you are not using it to 51%. You're making it more expensive for people to attack the chain -- without the faster miner, people will have to purchase and run more hardware, or pay someone to develop software. Releasing it publicly puts everyone on equal footing, which is a hardware based level of security. If that was the case though, I don't know why anyone would post about it, unless you're simply trying to drum up drama.

I don't know what FPS means in this context; how to check it or change it with this miner. I run MSI Afterburner to overclock my 5870 card: 990 core clock; 300 memory clock; no change to the default voltage. I use poclbm_py2exe_20120205, with these flags: -d0 -v -w128 -f1 ( not sure what any of those flags do... got it from the mining forum, from people with the same card and miner as me, and it seems to work fine with those other pools. ) Is it that -f flag I need to boost up? And if I do will I be able to keep working at my desktop without it slowing to a crawl? Thanks Yes, bump that up, and yes, you will be able to work on your desktop. |

So I'm still new to this and I'm trying to configure my cgminer/run_p2pool thing properly. I'm just curious if Cgminer is supposed to say that a 'share' is "Accepted" or "Rejected" because I traditionally get a couple Accepted when I first run the program than 90% of the time after that it says Rejected. Is this just because it's not actually getting shares or something?
What version of CGMiner are you using? I had a problem like that on 2.2.3, switching to 2.2.5 fixed it. |

I'm on Windows 7 64-bit. And I made sure I didn't have double instances running right now. Curious... I am at a college campus and they may be blocking the port somehow. I guess I'll have to check if I still get the error if I'm somewhere not on campus and report back.
Do you have Litecoin running? IIRC, they use the same port by default. You'll need to tell either p2pool or Litecoin to use a different port, if that's the case. |

Got up past 400 playing blackjack -- your apps are pretty slick, although I noticed a bit of hesitation on the BJ, not sure if it was my connection or not. Hands seemed fair, although I'd like a higher max-bet. (Nothing like putting it all on a single hand.)
Account is vanderbleek.

So which is a superior solution?
In my opinion, a solution that automatically spins off smaller p2pools, and balances the load between them. That said, simple web interfaces (where users logins are the payout address) are not a terrible idea either, but I don't think we need to build pools that connect to p2pool -- why not just connect those pools straight to the main chain? |

OK so the bitcoinplus is actually a web interface for a pool right? Do you have any info about this one? They don't have much details on their website. Also this sentence is a bit confusing for me: "When your computer solves the puzzle, you get 50 bitcoins. The puzzle difficulty keeps changing so that around 6 computers solve it per hour." But then they talk about years, so what do they mean by that? Or is that sentence just years old?  If you're confused about the "puzzle" it's not really a puzzle of the sort you'd usually think of. You don't make "progress" on it, you just have a very low chance of getting the answer per try -- faster cards can try it more times per second, and a CPU, in order to have a reasonable chance (95% or so) would take a very long time. On average though, six miners get lucky per hour. |
