Use GPU-z and check your clockspeeds and temperatures while mining, as well as your usage. Second tab.

You can find a comparison of ARM processors on the wiki. google: bitcoin hardware comparison. It is the first result. It is towards the bottom.

Pulling about 300 watts mining at my dorm. I don't think anybody will care too much when I have nothing to do with my 6950s  How are you managing that considering ~200W per card before PSU efficiency, the rest of the rig and the only-possibly up-to ~90% efficient power supply? Crazy undervolting? I intend to keep mining with my dedicated 5830 for a long time during winter, fall and spring. I've also invested in BFL a long time ago. I find the consideration of future value is often overlooked. |

The motherboard model is normally printed somewhere on the PCB. Usually between the add-in slots and the CPU socket or between the RAM slots and the CPU socket.
Are you only willing to ship USA?

I don't think you are going to get a lot of offers until you can either take pictures where we can read the fine text or provide us with model numbers by doing some research instead of saying "unknown". At least, if I were buying, that is how it would be.

from all accounts batch one of avalons had 300 orders 300 x 68Ghash=20Thash i know the 3 units that would be advertised to the community by the litecoin foundation, a well known blogger. and someone else (cant find much details on) arrived. but the other 297.... hmmmmm i was hoping/expecting a faster upclimb in hash rate. above anything ever experienced before. http://blockchain.info/charts/hash-ratemany GPU/FPGA miners got the hashrate up to 28Thash in december 2012 and just as the avalon news broke. so i was expecting a new high, over the 28Thash existent high. i guess its a waiting game. final thought: the 2 high spots could have been avalon testing some ASIC units so the average 'high' could be around 24-25Thash, many variables/possibilities need to be calculated. EG FPGA/GPU miners may flock to other alt currencies and leave only ASIC miners with their 20Thash of combined power in the next few weeks copy + paste = same amount of effort. I mean, you did copy and paste something anyway: the link  |

OMG please please doubleclick on the spaces between the column headers (A,B,C etc) so that all the rows automatically fit and so that we can read all the contents of the cells without clicking on them and each row only takes up one line.

I just happened to find this program today. Then I find out it is broken with the latest AMD drivers. Rolling back drivers isn't exactly an option on my main machine unless I find a weekend of spare time and my BAMT miner can't compile because it is missing dependencies and has write issues due to the wear on the flash drive.
This also seems to be the time to move this project forward to give people a use for their GPUs. The oclvanityminer looks interesting.

There are several contributing factors here. First off, Satoshi is almost certainly not a Japanese national. He might be ethnicly Japanese, but I would question even that. He originally used British spelling and grammer, and did not suffer from the gramatical quirks of a native Japanese speaker. Add to that the fact that there were zero translations of the White Paper into Japanese for at least 18 months after it's release, and it's easy to assume that Satoshi isn't a native Japanese speaker.
Furthermore, Bitcoin doesn't really offer much new to the trade culture in Japan. As a society, they tend to be very cash & local trade biased, and even online shopping isn't (demographicly) as big in Japan as it is in the (much more geographicly diverse) United States. Sure, they use the Internet to decide what to get, but oftentimes they can order the item online and pick it up at a store within a local travel distance for cash. Walmart.com uses a similar model. Even when they do trade electronicly, they actually have more advanced forms of electronic commerce than is presently available in the US or Europe, already having NFC enabled smartphones and such. In the US, the credit card industry has been secretly resisting moving away from the plastic card model and towards the smartphone app model because they have a huge vested interest in the prior model, while companies like Google have a head start in the latter model.
On top of this, his time-of-postings pattern on this forum lead me to believe he was in the US on the East Coast. That is what would match best. Perhaps he had irregular sleeping patterns, but unless he consistently woke up long after dark and went to sleep in the afternoon, his posting times wouldn't match someone living in Japan. Add to this the commonality of both the names "Satoshi" and "Nakamoto". Especially Satoshi. Basically, bitcoin was invented by John Smith. |

Seriously. They will have such an advantage with coin gain anyway, so for them to actually band together and take things over pirate style... But really asics will just make it better for everyone, especially if they just join pools, then everybody wins. Might not get as many shares but the blocks would be flying by so fast it wouldn't matter.
yeah super fast... at 1 block every 10 minutes... just like right now. |

Let's get a real discussion going. Let's start with picking apart my calculations based on incomplete information:
Avalon 1st shipment: 20TH/s finished during march
BFL first shipment: 55TH/s? finished during march? (rough guess of me assuming the total hashrate listed on the wait thread will be the same as the first shipment)
Asicminer, 1st setup: 12TH/s mining by late feb?
Avalon 2nd shipment: 40TH/s
BFL second shipment: ??-? (doesn't really matter since estimates of delivery of second shipment seem to be around late june)
Asicminer, 2nd setup: 72TH/s
Sooo.... let's assume 25TH/s+55TH/s+20TH/s+12TH/s = 112TH/s by the end of march
expecting to expand to at least 224TH/s by the end of June
224TH/s=31.29 million difficulty.
My personal guess is 35 million (aka ~250TH/s) for your poll, based on all this, since I expect to see shipping problems, resellers, people not mining 24-7, GPUs and FPGAs dropping out due to people with ASICs switching and some people without ASICs dropping out completely, etc. Plus, I don't expect everything that has been sold so far to be online or shipped by the end of June anyway.
250TH/s
= 34.92 million difficulty
= 0.86401318 expected BTC/day@60GH/s
= 69.44GH/s to solve 1 block per day
Interestingly, the SC mini single I have on order at 30GH/s should net me a bit more than amount per day that I got with my 800MH/s setup when I started mining seriously, once everything starts to level out. Of course, I expect the difficulty increase to incline at the same relative rate as it has over the past few months, once things level out.
I hope to have a unit that will break me even within 6 months and after that, I can keep hashing competitively enough to keep up the hobby.
These are my expectations. What does everyone else think?
edit: gorram smily on ? ? ?

Nice writeup. Been playing with these for years, and still learned something new  +1 |

The image just BARELY doesn't fit on my 4GB kingston SD card. I look forward to testing when you release the 2GB version you mention on your site.
If your using Linux and dd to write your image it will probably still work just pop it in. If your using Win32DiskImager I am not sure, did it write up until the point that it ran out of space? If it did it should still go. (I don't use the windows version all that much) The partition table will be foobar in both cases, it will just have a bung development partition and you may have problems mounting it but its not needed for mining. Sorry, should have mentioned more details. I was using win32 diskimager. It does not attempt to write anything and just lists the number of sectors required and the number of sectors on the SD card in the error message stating that there is not enough room on the disk (and the sectors required are just barely larger than the sectors on the SDcard). Maybe if I get around to it I will boot one of my machines into linux. |

So the next question jump is clear;
Why don't the chinese people have a fork of the Bitcoin project in their base language?
I was going to say stuff, but then I realized it would be easier to have you read this: http://en.wikipedia.org/wiki/English_in_computing |

mineforeman.com, you are amazing. I will test the image on my pi if I get the time. I have no FPGAs but have no other use for my pi at the moment.
Edit: The image just BARELY doesn't fit on my 4GB kingston SD card. I look forward to testing when you release the 2GB version you mention on your site.

How will it be the end of Bitcoin? If ASICs never arrive, those who couldn't afford them will rejoice and keep mining with their existing hardware.
Not profitable anymore, bitcoin need to stick to moore law otherwise hrate will crash  smartass You are forgetting about difficulty. If the hashrate doesn't increase, neither will the difficulty.
Delays were predictable. Saying "omg we did not expect these delays" is just a lie, so I believe nothing will arrive.
End of bitcoin is a consequence , bitcoin can survive only with enough miners, and people mine for money (no most of people don't care about freedom and this kind a propaganda or just as a "bonus" in addition of money), no new device, no innovation= no more profitable = no more miner (everybody's gonna go speculate on something else..)= end of bitcoin.
Another end of bitcoin could be the dead of Silk Road which is the real economy of bitcoin (22Millions $ a year), and I checked ALL the bitcoin stores in the wiki, there is no real economy behind bitcoin except people buying for speculation or people buying bitcoin to buy drugs.
No new device,no innovation= no significant difficulty changes =GPU miners continuing to mine and FPGAs becoming the defacto efficiency option for those with the cash. "bitcoin can survive only with enough miners" No. Fail
Less Hashrate = Less difficulty, which means more Bitcoins/Hash with easier work.
Fixed that for you. 10 minutes.
Actually asics may arrive I just don't like the way butterflylabs communicates it seems their methods are from "Communication for dummies, how to make people wait without riots..." or something like that.
Other thing I can't stand is people saying "wow bitcoin is so great this is all about creating freedom/community/payement/blablabla;;;" THIS IS NOT, bitcoin model is funded on miner PROFIT, no miner work for something else than money (I'm talking about people mining for more than 1Gh here...real miner) .
Last thing super annoying to read evrywhere , "bitcoin is based on a real economy" , this is SO WRONG, real economy is Silk Road and similar friends, I'm not saying bitcoin won't ever have a real economy but for now it's 95% speculation, either people order drugs either people are betting on bitcoin future (and hope to make MONEY).
People who are the community core (dev, blog, etc...) have another interest than money but it's a small minority (and they are also interested in money of course!).
Saying something else about bitcoin is just wrong, dumb and naive!!
This thread is a provocation, I'm willing to hear other point of vue and arguments! really!
Fun provocation. I helped you by posting random stuff  I treat bitcoin as an investment. If people buy it or sell it or mine it, I'm sure a lot of people treat it the same way. It does have a long way to come before being treated by the majority of people using it as a currency. Hopefully, that will happen over time and the investment will slowly pay off. |

Thanks to that tip from conspirosphere.tk I am now running at a steady ( ouch ) 79°C - 80°C
Are you keeping your rig open (without side panel)? That is mandatory for miners. My 58XX radeons are mining @64-65° C downvolted at 0,960v, core 800 (5830) -850 (5870), mem @300, fan @40% The best case ever is the cardboard box your motherboard came with, open. With the PSU hanging off the side I think it's better not to invest in a case at all. If you're fancy, you can get a server rack or fabricate something yourself... if not, you can put your stuff on a piece of cardboard. Use an eraser or something to jam between them to create some space if you aren't using risers. I have one system with 3 GPUs that have had their fans removed (and plate and fancy covering) and just have a floor fan blowing at them instead. re: efficiency, that depends totally on the cost of your electricity, though nowadays I suppose it'd have to be Pretty Damn Cheap to, say, run a 5830 at 1020 core @ 1.163v vs 920 core @ 1.063v. I run mine at 920-160. I think you lose 1 or 2 mhash vs 300 and the 256 worksize... or last I checked, anyway oh, i should mention that whilst a floor fan will always provide more cooling, one must angle it properly to achieve maximum efficiency. i like the use old DVD drives and card casings... and those old honeywell fans are tons better than the new ones. all this nonsense about fans being quiet. i was looking around amazon for a 'loud as shit' fan that puts out a lot of air, but couldnt find any |

please add additional options, if possible:
No - Had GPUs, will keep mining
No - Had FPGAs, will keep mining
No - Had mix of both, will keep mining
Yes - new to bitcoin and going ASIC
I know these will likely have few responses but I am interested in if anyone is considering those options.
You could condense the first 3 into "I will mine with what I have now (before ASICS) for a long time!"
I know that once I move to ASIC, I will keep GPU mining in the winter to avoid using my oil heater. Even in the summer, I will likely keep my 5830 single unit mining.
