update on this.
I installed all the mining systems ok and started mining litecoins with p2pool using cpuminer.
but it looks like its hopelessly unprofitable using the litecoinpool mining calculator. I entered my Kh hash rate as shown by my p2pool stats for my nod, plus the difficulty rate of 223 which is displayed on their site.
Does anyone know, is this the standard difficulty rate for litecoin or does it just relate to their pool?
Anyway if its the former as I think it is, then the result shows that its completely unprofitable and lossmaking for me to try and mine litecoins with my laptop.
probably just as well since it could burn out the processor and parts.
so, no more mining, ive turned the system off. pity, just when Id got it all working.
You know LTC difficulty just jumped higher 5 hours ago right? CPU mining is obsolete now (it made sense for both BTC and LTC in the past). Soon GPU mining for BTC will be obsolete. Using a CPU now is like trying to turn a doorknob with needle-nose pliers. Sure you might be able to do it after 10 hours, but why not just use the right tool in the first place. |

I thought the 5 GH/s seemed tempting too, even if just for the hell of it as it probably won't get much profit, and I would buy it, that is if they shipped and I knew for a fact that I wouldn't have to wait more than a month for my purchase to arrive.
They are going to ship in two weeks. Earth weeks or Jupiter weeks? |

Can we close this thread and start a forum thread of confirmed ASIC scams? It's getting difficult to keep track of them all without one central list. (cue the conspiracy theorists)
It's pretty easy to keep track of the legit ASIC options. There is only one legit company as of right now and that is Avalon. All others are scams or vaporware. You saying ASICMiner is a scam? |

Did you buy the Mobo direct from Amazon or 3rd party vendor.
3rd party vendor might have had really old stock and you might need to flash the BIOS to support the newer chip. But I thought the 990 chipset supported the 4100 (maybe not the 890).

After BFL Batch 1 & 2, and Avalon Batch 3, and ASICMiner we'll probably be in the mid 40million range - maybe by June? Then the oddities like Helveticoin might come in or some other unknowns. Either way GPUminers will be in Altcoins. From then on it will be an all out ASIC arms race. 60-100 million by July? You buy more ASIC if you think BTC will go to 1000USD never knowing what the cap on hashrate will be. Electric rates will start to matter by this time next year and the Gen2 or even Gen3 units will start coming out.
Or BTC has another issue and something like LTC or PPC takes over - unlikely but you never know.

Bottom line is that your free to take a refund if your not happy to wait. Everyone should be requesting refunds, because the risk that BFL will go out of business or be shut down grows with each day they fail to ship products that were 100% paid for months ago. But anyone who was expecting instant overnight returns by being first to market, is deluding them selves. If you seriously had that expectation, you probably shouldn't be spending money on something you apparently don't understand how it works. The promise of being first to market is PRECISELY what BFL sold...honest abe. The fact that they've failed so spectacularly while lying about nearly everything at every turn while Avalon and ASICMiner have succeeded in designing, building, and delivering ASIC mining hashes in less time should be a wake up call for BFL investors, but you need smelling salts to rouse many out of their slumber. Hrm interesting. I had only just first heard about them about 4 or 5 months ago. I lurked on the forums and what not for a few months and did my research. Avalon's offer is way more expensive and seems to be less well designed. ASICMiner, I really don't know much about them. I know you can buy mining shares on their system, and I spend an hour or two trying to figure out how it works but I really couldn't. The BFL solution looks the cleanest, and most high end. If they were selling on being first to market thats news to me. I had not seen anything that promised that anywhere. Maybe I'm just late in the game. You joined in 2011. I'm not sure how you could have missed their promises of being the first to deliver ASIC unless you took a long hiatus from BTC. If they didn't make this promise I would have used fiat to pay for my Single. Instead I tossed 208BTC into a dark hole. What's the point of asking for a refund when I would get what, maybe 10 BTC back at the current rate (or 6 BTC at the time of your original posting). I'm pretty sure my first day order will make 6 BTC, but will never make 208 BTC before melting. |

Interesting transcript with Dave from BFL I found on that reddit link. It confirms BFL doesn't have a set shipping date yet, and they are full of shit when it comes to shipping "next week". http://pastebin.com/HpxTwUNWColor me shocked. Ready for some more color? There is no 1164 SW Hillsdale in Topeka, KS. In fact, there is no street at all named Hillsdale in Topeka, KS. But there is such a place in Shawnee, KS, just outside Kansas City. My guess is that in the backyard one would find chickens. Please surrender your Jr. Detective badge and water pistol sir...  But, Andy... You know more than 3/4ths of the board won't know the reference. |

Some boards disable some slots depending on which slots are populated.
Alternatively you might have to do a mod on the slot where you short a couple of pins on the mobo for it to detect the riser.
Check the hardware subforum for the post on that. It has pics on how to do the mod.

That 0.08 (which is probably not lost) will be money well spent on learning how to read blockchain data. Consider it BTC school.

On that mining hardware page what you find is a lot of extremes. Like the person only getting 525MH/s with a 7950. Or somebody mining with a 7970 outside in a snowy area so that they are able to overvolt the card to crazy voltages and fan speeds.
Any time you run multiple cards the weakest card will bring the rest down even if you use independent settings. The heat from each card increases the power usage by requiring more fan speed and voltage to remain stable.
Expect 310 from each card, and anything above that is good luck and some skill with tweaking.

Not sure about you guys, but the recent drop in price has taken the sting out of the waiting for my rigs.  Haha, if BTC dropped to $2 then it would only be a loss of $10-$12 USD per day lol. And my Batch 3 units were only $212  Honestly I'm more concerned about BTC commerce than the price. The price run made BTC unusable for both buyers and sellers. |

I thought the name looked familiar but wasn't sure. I do frequent Anandtech and HardForums. Yeah I would just shut the thread down at this point.

Have you seen the prices today? May be a good time to just spend the $700 just buying the coin outright if you believe in them.
On the long term it is better to mine. Why spend $700 when you are not sure how much they will be at any given time, you could get a bad deal or a good one just as easily. Build a cheap mining rig and reap essentially free (aside power and hardware cost) coin forever, which is immune to what the current exchange rate is because no matter what 1 BTC/LTC is still just that regardless of how much they are worth in fiatworld at the time. Id rather have a miner someday pulling in BTC out of the air when they are worth much more than they are now then simply buying a few coins. Mining is ongoing, a one time purchase of BTC won't generate you any more coins after that unless you like playing the markets. (which really shouldn't matter to you if you are a driver of this tech and not just some hot shot Wall Bankster parasite in it to make a quick buck and then deride the whole system because it didn't make you an overnight millionaire. If you are one of those, we don't serve your kind here, the droids will have to wait outside) Plus mining is good for expanding and securing the network at large, so there is that too. It is only better to mine if difficulty stays reasonable. ASIC are destroying GPU mining profits. The only thing that kept it alive was the price run. If you're mining LTC, you'll be mining at a loss soon too as the people with free electricity can convert from BTC to LTC mining. Anybody paying for electricity will be on thin margins. If you expect the coins to go up in value, why even bother mining them when 1 click gets you the coins. If you leave a miner on and it spend $3 a day in electricity but only produces $2 of coin what's the point? You can buy $2 of coin every day on an exchange, save $1 and not have to deal with a nagging wife or your cat getting shocked I'm not discouraging mining (you can tell from all my posts here I've been trying to help noobs) but there is a point where it is stupid to plop down $700 to chase after $100. If it's a learning process then have at it. If the goal is to make money, just buy the coin and enjoy your 10 hours saved by going to the beach or working a job to buy more coin. |

Drg you said elsewhere that more then 3 7970 will fry the pcie*16 power pins. So he will need at least 1 Power riser no for 4 cards ?
I personally haven't put more than 2 7970s on a single mobo so I don't know if 3 would be OK. For 4 I would definitely use a powered riser. My 4 card rigs use 6870s and they're not as demanding as a 7970 obviously. |

BTC for about a month then probably LTC and converting them to BTC to cash out
Right now BTC mining is on par with LTC as far as income. If LTC difficulty keeps going up there would be no point converting, just stick mining BTC. |

No need to get another 7970 unless you want to crossfire later. 7950 is better bang for the buck for both LTC and BTC.

i have a xfx 7970 black oced by factory i didnt want an oced model as i really dont like the idea can anyone help me get it et to original 7970 settings
I have XFX cards from the 6 series and the Double Ds are nice. The 7 series XFX really skimped out on parts and quality control. Everybody agrees they're thermal nightmares. |

Just a short answer for I am at work:
CPU: Take a smaller and cheaper modell! A Sempron or Dual Core Athlon should be sufficient.
MB: ASROCK 970 Extreme 4: Cheap and has 3 Slots.
PSU: Good
Ram: Good (For BTC Mining: 2GB, für LTC: 8GB)
GPU: 7950 is actually a pretty good modell. MSI Twin Frozr are good. Gigabyte Windforce (with 3 fans) also also good. Look for good Coolingssolutions on the Card. (I think if you want to wait for the MSI, you would wait long. They are sold out everywhere.
It doesn't matter if INtel or AMD. Take the cheaper system. You don't need CPU computing power
Agree with this. The only reason to buy a good CPU would be if you want to upgrade your main rig and use your current CPU in the miner. I use pretty much Celeron G530s in my Intel builds. I used Phenom 840 on my AMD builds only because Microcenter had those cheap combos. If you can get the MSI I would go with that. Lot of people have good experience with Gigabyte but the 10 I've got from Frys are all crap. |

Unless you have 1TH/s mining BTC or 40MH/s mining LTC you shouldn't be solo mining unless you really like gambling. The variance risk is too high. And if you like gambling just spend your pool earnings on Satoshidice or Roulette or something.
