Wow look at that cliff  Upon looking what is the second cliff on $5.20 doing? Someone expecting to cash in if the price goes back to $5.20? Sounds to me like the person is expecting a drop to 5.20 and then a pretty sizable rebound  |

That could be a possibility but do they actually have the capacity to increase the network by ~4-5 Thash/s? That's a lot of power, I'm sure that even though they're ASICs/FPGAs than 5 Thash would be at least 200-300 kW or more.  If true, we're only talking ASICs (not FPGAs). Again, I would expect to see a performance jump like we saw from CPU to GPU along with the efficiency jump we saw going from GPU to FPGA. Just a 3x increase in performance with a 3x decrease in power consumption could yield a board running a GHash/s on about 10 Watts (or 10KW per THash/s). This is speculation on my part of course, but it would have to be significant enough to make BFL offer a previous generation obsolescence protection package. That would be quite incredible if the ASICs could actually have that much efficiency. The problem is, once efficiency goes up, the difficulty will go up as well, which will eventually even out the playing field for profitability no matter how advanced the technological advancements are. (Just like how CPU mining used to be as profitable as GPU mining is now due to prior lower difficulties) |

I think, 50btc.com will remind us about this good time, when the grass was greener, the reward was larger...
When the value of Bitcoin was lower... True, hopefully the value will go up and completely compensate for the reward halving overtime when the economy grows big. At least that should be the case, since it is evident from the price staying stable and even increasing despite current mining rates. |

I bet they don't ship in any reasonable quantity until 2013. I'm watching and waiting for OpenASIC - https://bitcointalk.org/index.php?topic=76351.0 - with it being opensource hardware its more likely to be cheaper and therefore more widely available and used. I agree on this possibility, and am watching it closely. Knowing the slow to ship history of BFL, if their pricing seems overly expensive, it would seem tempting to wait & see what the openware option provides. Goodness hope that prediction is right. BFL please give me time to mine enough with my GPUs to get a BFL single add-on in the wake of huge difficulty increases. |

We could be seeing test runs of some serious ASICs? We know BFL will be making an announcement soon regarding their BitForce SC and third generation of hardware.
I wouldn't be too surprised if BFLs first batch of circuits are made and are being benchmarked under different conditions before being announced.

Thats one some crazy variation with 40% increase, dont you think?
Block generation is supposed to average 144 per day. Playing with a poisson distribution calculator, it seems there is about a 10% chance of a day with <= 128 blocks and a 10% chance of a day with >= 160 blocks. That's already a 25% difference. If you are looking at peaks and valleys in the graph lasting significantly less than a day, say 6 hours, then the average is 36 blocks with about a 10% chance of <= 28 and a 10% chance of >= 44, which is a 57% percent difference. So yes, I think you are mostly seeing random variance. (Hopefully I got the math right.) So, in that case, the actual network hash rate is around 12 Thash I believe? |

Hello, A trend I have been noticing for quite awhile is how much the total network hashrate varies. It regularly jumps from ~11 Thash/s to 15 Thash/s and vice versa. Why would people power off their rigs like that so often? I see no reason for it to vary that much especially since it seems stable over courses of days and then finally takes a sharp increase or drop, indicating that it is not due to "part time" miners. Or is the reported hashrate simply jumping around due to the luck and variance of the rate of solved blocks, while there is actually a stable constant hashrate for the most part? Just a question of wonder.   |

GG. Someone with those ethics shouldn't ever be allowed to ever do business with anyone. You know it's wrong and yet you keep his Bitcoins. Give him back his 22.5 BTC... You still have it, what is the point of keeping those bitcoins? That's just a waste on your reputation, it has been completely tarnished  |

In short answer : Yes, but you shouldn't.
Long answer:
It can be used for mining, however the design of all Nvidia chip GPU's don't work well compared to ATI, due to their differences at a hardware level.
At a software level, the mining process mostly uses OpenCL to make use of the "Shaders" (hardware) on the GPU. Nvidia and ATI both have these, but Nvidia took the approach of a few complex ones and ATI too the approach of lots of simple ones. The mining process is relatively simple, thus having lots of simple shaders is very efficient for this task. Nvidia more complex shaders in some areas are less efficient and thus far there has been no way to compensate for that. There is in the region 5-10 less bitcoins generated out of a similar power (watt) consuming processor between nvidia and ati. This makes Nvidia GPU's so inefficient you actually spending money to make these bitcoins rather than turning a profit, which generally speak you will always do on an ATI GPU.
Both GPU markers, choose these different paths quiet a few years ago and ATI kept theirs when they realise they had adopted a secondary market outside of gamers, Nvidia already had the TELSA to bring in the more Scientific use of GPU so were not going to change their design.
Thanks you. For now, i will sell stuff.. maybe the next year i will buy one of these ATI cards. Wich one its better for mining? This wiki, keeps track of popular mining cards and the results from them. https://en.bitcoin.it/wiki/Mining_hardware_comparison#Popular_Mining_CardsGenerally speaking the 5xxx series has been very popular and now retains a good amount of value since they haven't devalued much in the last year. However the 7xxx series (latest series) is a bit more efficient, however they will devalue by next year, possibly ruining it's resell value if that is something you plan to do (many do). So by next year you can probably pick up a 7970 for a good price. It changes all the time, so their is no good answer that far ahead. Also by next year, FPGA and ASIC could become more mainstream, due to a change in difficulty of the blocks and reduction in value from them, so buying GPU's for the purpose of mining might not be ideal any longer. The 7970 can compete with the FPGA miners out there. I can undervolt and underclock and manage to get 500 Mhash/s at 80 watts a card. That's already very competitive with the BFL single. If you have cheap electricity and the price of BTC is able to adequately increase after the December block reward halving mining with 7xxx is still a very, very good choice. |

The problem is racing cars have constantly burnt out tires, while graphics cards have electromigration and total errosion of GPU long term Not in the useful mining lifetime of the card. For a proper analogy, I'd equate worn tires to a burnt out fan, and electromigration to a blown engine. Great analogy But if any "parts" in the actual engine break then you're doomed. Anyways it's much better for me because I wouldn't gain much and it helps keep the temperatures low and my power consumption down. |

Try uninstalling and reinstalling the AMD Catalyst drivers.
That has fixed problems I have had in the past.

Sorry for reviving a 2 month old thread but upon insight then lost bitcoins really wouldn't affect the bitcoin economy.
The lost bitcoins would be so negligible, even now it is definitely negligible.
Since bitcoins go up to 21000000 in integers, that's quite good. It also goes in the decimal places as well.
If .00000001 BTC became worth $1 in the future if it were globally adopted by many people, then you could easily revise the client to handle that in integers instead, and "move" the decimal place out.
Realistically, we can represent 2,100,000,000,000,000 units.
The amount of lost coins is probably very small, and you could just possibly add more decimal places in the future to bitcoin to accomodate rising deflation, which would make bitcoin theoretically infinite despite the "finite" 21,000,000 coins.
This is also a reason why introducing endless inflation would be such a bad idea.

Reading that I thought it said 1 TeraHash/s. Almost gave me a heart attack |

Website is being extremely slow.
Really? Website is fine for me. |

Its paid for anyway, this does not cost me anything
It's a waste of electricity even if it doesn't cost you anything. Please put some considerations to mother nature  |

LOL  A finite 0.1548 Bitcoins gone for good |

Ozcoin is by far the best.
Personally I use GPUMax and use Ozcoin as backup but they are about the same payment wise, so it works out whenever GPUMax doesn't have public work available.

Simple GPU miner with 1x 5850 and 1x 7970. Pulls 370 watts at the wall with some tweaking of the GPUs. 59C for the 7970 and 68C for the 5850. 850 Mhash/s P.S. Picture was taken by Potato 2000 Only 850mh/s? Thats poor imho. One 7970 can do ~700, one 5850 can ~320 easy I don't like to mess with overclocks, it would get quite hot in the garage, instability issues, temperature issues, and high power consumption. The higher hash rate vs power consumption isn't worth it. In the end you'll have accelerated electromigration and dead cards. pls wake up from ancient times with Pentium CPU. You can increase GPU speed and reduce Voltage in same line. When you go to set a Formula1 Race team, you can not start with a Golf R36 and hope to win. The problem is racing cars have constantly burnt out tires, while graphics cards have electromigration and total errosion of GPU long term |
