Sounds cool, and I'd definitely like to give it a try, but it won't be implemented until block 24000? I guess you guys need time to get it going, but that will be quite a while looking at historic trends. On 7/21 block 16128 the difficulty drops and people will rape namecoin for a few days, then drop out when difficulty erupts again (2-4 days later?), after which it will take 1-2 months to reach block 18144, etc. At that rate it will take half a year or more to reach 24k, is that intentional?

That only displays power draw for the core I believe. The total power draw of the entire card will be much higher. |

As with most things in life, the best is probably the middle ground. 67C is quite cool, and 76% fanspeed is rather high. Probably something like 75C and 40-50% fanspeed would last you quite a long time. You can reapply lubricant to the fans bearings every couple of years to increase the lifespan of the fan as well, assuming you do it properly, as that is the main issue fans running constantly run into. The MTBF for fans is typically something like 40,000 - 50,000 hours for cheapo fans like GPUs use, so expect 4-6 years of 24/7 use if properly kept up.

Hmm, interesting. I already have tons of dummy plugs but it'd be nice not to have to worry about such things in the future. I'll give 11.7 a whirl later today and report my findings  |

I'm thinking about purchasing some extender cables to keep my cards from being bunched up. I've seen people with some wierd ways of holding their cards up (threads, twist ties). I was wondering if there is some sort of little simple stand that they can be placed on.
Please point me to the direction.
If not I'll invent one and have some chinese people make them in sweatshops for .001 btc a day. No not really but you can if you want.
I use a shoe stand from the rack section of Home Depot. The cards fit nicely between the slots, but be careful not to knock off one of the resistors as they line up perfectly with the metal rod and can easily be damaged.  What cards are those? Are they doing okay on a 850w? 5830s, they're doing great with a 850 watt psu, even the core overclocked to 960-1000mhz. It won't handle 5 overclocked though.  Also running 4 5830's with the same psu...actually 2 rigs exactly like that...going strong after a month...I will say the 850w ones feel hotter than the 1000w psu...could just be design though...they seem fine. I'm running 4 5870s on an 850W, I ran them on a 750 for about 2 weeks while I waited for the 850 to come in. I woulda left it but the PSU got uncomfortably hot, and I'm a hardware wuss. I like some of these setups, I think the cost for extenders would be worth me not continuing to go deaf (I have a bunch of sandwiched cards that would run at least 10% less fan speed if they were spaced), but sadly I have no tools for the aluminum. I'm considering the super ghetto shoe rack rig though, intriguing. |

All investment of any kind is risk. Bitcoin mining is one of the least risky I've seen. In fact if I were less lazy I could essentially finance a huge undertaking like NetTecture, without use of almost any personal savings, and it would require bitcoin to crash and burn almost completely within about a month of my purchase for me to be out any significant capital. And to be fair, 40 6970s (I can't buy wholesale like he can, but I'll use his numbers) is essentially a job.
I enjoy bitcoin, but not enough to devote that kind of time to it however. Close, but not quite. If I didn't have to move states I might consider it heh.

Not sure what your question is. A hash is a hash is a hash. For pools? There is no advantage to having the same card generate multiple work threads, except that some people suggest that you might squeeze a couple extra Hashes out of the parallelized GPGPU structure. I don't really see it myself.
As for a single worker being split between multiple GPUs, again not sure exactly what you're asking, but I have a single worker designated for each of my boxes because I am lazy, rather than per card on each pool I use. So if that is what you are asking then yes it's fine. There is no difference between a single worker or multiple workers on the pools side.

If anyone wants to get their feet "wet" go buy a used 5770. Hands down, nothing comes close for the mh/s per dollar. It's easily 2-2.5mh/s per dollar. (Used ones go from $60 to 80, 90 for new and you can get 200mh/s out of them super easily.)
I'm not certain where they got their prices from, I hardly doubt the 6990x2 is the best performance for your dollar. They also didn't mention 5830/50's.
The 6990 is the best price/performance if you pay for electricity (like most people). That's what they're measuring. Say wha? @ both of you. Both are not great price / performance. 5770s are ok Price/Performance, but poor Price/Rig (Low output for all the other costs that you have to pay). 6990s are like the opposite, decent Price/Rig, but bad Price/Performance and very hard to even find. Not sure why the article only shows CFX 6990s, but still $1600 for 1579 MHash is pretty poor, compared to say 327Mhash for $210 for a 69501gb ($1.01/MHash vs. $0.64/Mhash). The kings are still the 5xxx series, but it does seem the 6950s are the best bang right now, especially if what other people are saying is true, about being able to unlock extra shaders even on 1gb models. But you didn't even address my statement at all. I see absolutely nothing about electricity prices, or even theoretical electricity prices, or power consumption! I consider power consumption reasonably negligble. a 6990 uses roughly 20 watts more than 2x6950s in crossfire (a 6990 is 2 6950s on a single PCB), and 50 watts less than 2 6970s in crossfire. 50Watts over a year is roughly $48 in power bill. To me that is an amount that is unimportant to consider given the much more real variability of present concerns with bitcoin mining creation. |

You should have made the clothesline longer so you can dry your clothing at the same time.  Good call, I've already done this, not with a clotheline, but I spilled a buncha water right next to my mining rig  , quickly soaked it up with a towel then dried the towel with the mining rig Are there USB video cards? I've never heard of such a thing. |

If you aren't paying taxes now, you are most likely breaking the law. So it might be worth the peace of mind to even things out but be on the right side of the IRS fence.
I've considered going to industrial power, as I live in one of the most electrically costly areas of the country, and also the wiring is awful in my apartment (30A for all accessible sockets), but in the end I'm too lazy to expand beyond where I am. If you can do it easily, quickly and without much cost, I would see it as worthwhile, if not, I would expect it to not be a great move.

The network is back down to 11.46 THash/sec on bitcoincharts.com, as a few smart people stated, this was just a bit of luck variance, not any JPMorgan conspiracy or whatever. |

idk :< let's say your PV has 3kWp. at ~10% efficiency that's 0.3kW. you'll get ~750€ / year from government and you won't be able to use your PV for your own use at all. (if you had decided this back in 2004 you would get ~1500€ / year). if you decide to use the electricity generated by your PV yourself, you'd get ~16 cents per kWh, so ~410€ / year + ~2600kWh for free.
they will stop paying you after 20 years. so if you install your 3kWp PV now, you'll have earned 15,000€. 3kWp costs about 11,000€. that's less than 2% profit per year which is less than our inflation rate. if you use the electricity yourself, you'll get 8,200€ and 52,000kWh. that's a pretty good deal (0.22€/kWh).
after the 20 years you will still have your 0.3kW PV, although i highly doubt it'll last much longer by then.
downsides: you have to pay for maintenance, which is probably not too cheap.
well, it's like mining bitcoins. you should have started your photovoltaic yesterday.
I'm confused, you get paid to use your own electricity? yes - if you decide to buy/install PV in germany, but only for the first 20 years of operation. they encourage us to use renewable energy. of course they won't pay for electricity which you get from your local supplier, only the energy you produce with your PV. edit: the thing is.. it's not too profitable, because your PV is expected to meet death not long after 20 years. if not, it's going to be at least a lot less efficient by then. Yes, indeed. That's still pretty interesting, but seems a huge payout someone must be subsidizing. Here we do it in reverse, for example: http://www.northerntool.com/shop/tools/product_200441246_200441246?cm_ite=4570001&cm_pla=Alternative%20+%20Renewable%20Energy%3EBattery%20Backup%20Packages&cm_cat=Google&cm_ven=AggregatesA 30% Tax Credit (meaning you can write off 30% of the cost from your income). So we incentivize people for the upfront costs, rather than continue to pay them down the road. Seems like it might be better your way though considering the difference in rates of adoption heh. On another note, this system was what surprised me pricewise. 22Amps (at 120Volts) including batteries, panels, transformer, and all for $2k seems like a steal. 22Amps is enough for about 2 full mining rigs. So I envision 3GHash/sec for about $4,500USD and no electrical costs for the next 20 years. If I had a house, given my electrical costs here (.4USD / kWh) I'd be thinking long and hard about that! |

Well as mentioned, ambient makes a lot of difference, make sure you have adequate case flow. I have a rig with 4 5870s all shoved together like sardines. They are currently running at...82C for the hottest (middle) card, with a fan speed of 54% (my poor ears can't take much more than that).

I'm tempted, as I quite enjoy SC2 and wouldn't mind getting better, my only concern is how ridiculously stupid the ranking system blizzard created is.
This new 1-match placement is crap. Even more than before. I placed into Platinum Rank 24 after one match against some horrible protoss after I hadn't 1v1'd for like 2.5 months. I placed into Platinum in 3v3 after losing my placement game to triple diamonds. Maybe when the ranking system makes more sense and I can get a grasp on how good and/or bad I actually am I could consider such a service.
Season 3?

It might make more sense to offer a graduated plan. Say a new pool operator wants to lease 50GH/s to look like they're not just crap, and they pay 110BTC to have you hash for roughly 2 blocks. So now they have 50GH/s to their name to attract people, and they attract 35GH/s of other people to mine for them with their now 85GH/s. Let's say they are lucky enough to have their variance be low and they find 2 blocks in the 2 days or so you've allotted them, you go your merry way with 110BTC + 59BTC (- whatever fees) and suddenly the pool only has 35GH/s.
People may think something terrible has happened, time to abandon ship.
More of a pain in the butt, but also seemingly more attractive to also a "come down" option, to bleed away hashing power rather than abrupt drop. I have no real suggestion as to the execution of that, for you to figure out.

HD5870x2, 844, 15 ($225), $0.00 thanks to solar panels even at night. NOOOOOOOOO! You solar panel people are going to drive the rest of us out of business. Those things are not cheap. They cost multiples of $10,000 to install, even for a modest system. So it's not "lucky you -- you get $50 in free bitcoins every month" but rather "lucky you, you could afford a $25,000 solar panel system". What I'm saying is -- the free bitcoins is the LEAST of that person's good fortune. Just like those who got into BTC mining in January 2011 (or earlier!) are better off, likewise those who got into the game of LIFE earlier have an advantage. Every year, inflation eats everyone alive. Those who got "established" in the early 80's, for example, will have paid less for everything, even relative to their lower wages at the time. Everything's more expensive, and "harder" now, since our dollar has lost more of its value than it had lost in, say, 1985. Those people got to buy their houses when real estate was much cheaper, for example. Plus the longer you've been working the more disposable income you tend to have, all things being equal. That is, comparing the same kind of person at 20 vs. 50 years old. Not True take a look to Germany there is Solar and Wind Power Booming since 3-4 Years (long before Fukushima) You just simply Rent your South Side of yout Roof to a Firm who sells the Power so you dont even need to Worry if something gets broken. We get through the the Rent for the Roof around that Money what our yearly electricy bill costs... How much does the German government subsidize that program? i'm not sure if that's exactly what you mean, but it started 2004 where you got 57.4 cents per kWh (at less than 30kW). it slowly declined until 2011 where it's 28.74 cents. gonna go down a lot in the future. overview (english) : http://en.wikipedia.org/wiki/German_Renewable_Energy_Actin-depth with tables (german): http://de.wikipedia.org/wiki/Erneuerbare-Energien-GesetzI think what he means are what are the goverment monetary incentives for the program, as most governments have to do something to incentivize solar power. In the case of the german act it looks like there is not that much which is cool, if I read your page right there is no tax burden at all on the german people to promote solar energy, just slightly steeper charges for those who consume more (is it tiered? not sure), and alternative energy gets preferrential treatment, not too bad. Germany benefits from ecnomies of scale I believe, since they have some of the worlds largest solar production facilities located there and they are one of the largest consumers as well. Private inititatives backed by public support can't hurt. I'm surprised by how cheap solar is now though, while still expensive, it's gone down dramatically. A nice trend for once |
