What other measure would you guys suggest to meet existing legal requirements? Trying to convince lawmakers that bitcoin should be anonymously traded is an absolute non-starter. If that is the foundation's opinion then bitcoin may be declared illegal and the tracking of coins will move to law enforcement. So, what are our other options?
NOTHING. Mikes Proposed change is unacceptable. There is the option to do nothing. The next update to the reference client could be done by a group from Asia, or Russia, it does not have to be done by the current devs. If US law makers and enforcement wish to do something then let them, and when they and their partners finally understand the concept of a de-centralised global currency then they might realise that the rest of the world will continue without them. EDIT: Pandora's Box has been opened, Good Luck with shutting it. |

I don't think vendor's bios is undervolted right?
Stock vendors F43 BIOS runs at a lower voltage than the later BIOS, undervolted and run cooler. |
|
|

...
You can still undervolt it with afterburner right? Cause most people usually don't wanna flash their GPU unless they are having like 100 of them... flashing GPU will void the warranty...
Some 7950's you can and some you cannot. Flashing the BIOS with the vendors own BIOS does not void the warranty as they supply both the BIOS and the tools to do it with, check out the vendors download sites. With a dual BIOS like the 7950 if a mistake is made in flashing it then you can flip to the working BIOS and then flash it back to the original. |
|
|
|
Yes, it can be flashed. But why you wanna flash it when you only have few GPU?
Heat, the F43 BIOS runs a lot cooler when mining especially the VRM's which have a tendency to blow if they get too hot. Running cooler also means that less Watts are used to produce the same amount of shares. |

Right on, it seems like people are saying go with the 7950's.. I found a few builds online and they all use those cards.
If I plan on having 4 cards will I still need a 1200w power supply?
200w per card and 100w for the motherboard/CPU/mem gets you very close to 1000w, I would go with the 1200W as it will last longer because it is not being pushed too hard. |
|
|

I did that, my batch file for troubleshooting was just
cgminer -o insertpoolhere.com -u username.1 -p password -I 11
This was with default clocking on the cards. When I raised the intensity to 13 I started getting hardware errors for both cards.
There is a known problem with some earlier motherboard PCI-e controllers and AMD cards so make sure that you add the SETX GPU_MAX_ALLOC_PERCENT 100 SETX GPU_USE_SYNC_OBJECTS 1 commands in your command file or set them as system wide environment variables in Windows for ease. If you still have problems then use the -d option and try each card individually as there could be a inconsistency between the two that causes the problem. It may mean that you have to run two instances of cgminer with slightly different settings, one for each card. |

Great, thanks.. I'm not sure what you mean about mining BTC with the 7970's.. I was under the assumption BTC minig with gpu's is dead, if not dying.. Regardless I think I will go with the one 7950 for now and order my other parts online.. while they come maybe I can find another 7950 or two for a good price.
I really dislike buying new items (everything I own is pretty much second hand) but I may make an exception for the other cards I buy.
What would the requirements for the rest of the pc be with a 4 gpu rig? Thanks again in advance
You can still mine BTC by GPU it is just inefficient unless you have free electricity and access to enough hardware to make a miner but there are some that still use GPU's just because they can or want to. 2nd hand is good for mining  run it till it dies and then get another |

I'm not even sure how to ask this question so here goes: The bitcoin mining network is hashing away and pool X finds a block - question: once a miner sees that a block is solved, how does it know where to start mining the next block? Example: - block found - network notified - Miner 1 > starts to brute force the next block by trying 1111, 1112, 1113, 1114 - Miner 2 > starts to brute force the new block by trying  - Miner 3 > starts to brute force the new block by trying - Miner 4 > starts to brute force the new block by trying - Miner 5 > starts to brute force the new block by trying What's to keep all 5 miners from starting at the same starting position and therefore (basically) finding the 'solution' at the same time? Is there some sort of randomization calculator built into the software so the miners all start at a different point?? I mean if I have 5 miners going myself and they are all trying to solve the same problem and they are all starting at the same start position they would all be doing the same work! I hope this makes sense - sorry for the crude example! You might want to start here http://codinginmysleep.com/bitcoin-mining-in-plain-english/ |

Thanks for the advice, I have another option.. 4x 5970's for $950 (can) but they are a couple years old with no warranty left.
My question is would it be worth it to wait and try an find individual cards (i'm looking to build a 3 or 4 gpu system) like the 7950 that I'm considering buying and build my rig from scratch or should I go with the 5970's with no warranty? I hear cards die quickly when mining so I'm tempted to go with something with warranty, even though the 5970's are a good price.
Would the fact that they are a couple years old affect the hashrate? or more likely to fail?
Personally I would buy 2nd 7970's for BTC and 7950's for alt-coins because of their lower power consumption which will keep your electricity costs down. |

So I've started mining for alt coins with a 5870 and a 6950 in my rig. I did a little test run without optimizing anything to see if they could handle the load (I just set the intensity at 17 for both of them and left them alone for a day or so). Seemed like they were fine. So afterwards I did a little overclocking (and I really mean a little, like 50-100 mhz overclock), I raised the intensity to 18 for the 5870 and 19 for the 6950 and left them alone. A few hours later I come back and I see that the 6950 has spit out some hardware errors (I think it was around 4), so I lowered the intensity and tried again. This time it spat out double digits instantly. So I removed my overclocks and set them back to 13 intensity for both. Now they're both spitting out hardware errors right when I start CG Miner. So I've been troubleshooting for the past few hours, looked through forums for solutions and I've removed CCC (I had the most recent one) and reinstalled 11.1 and 12.1. Didn't help, CG miner was still showing hardware errors. So I tried using an older version of CG miner and for some reason the hardware errors stopped. Is there a reason for this? I'm stumped as to what caused the hardware errors to continue. And on a sidenote, can these hardware errors actually harm my cards? If you managed to read all the way to the end, I applaud you and thank you.
What command options have you specified? I would also consider going back to the basics of just using cgminer -o 'insert URL here' -u 'insert username' -p 'insert password' -I 7 -k 'kernel_of_choice' --auto-fan -d 0 --remove-disabled tuning that one cad and then doing the same with the other by using -d 1 that way you then have a good set of parameters for both that you can then run together and raise the intensity until you get hardware errors, driver crashes, etc |

thx. refund from beastlymac will come in the next 24h then I will send it out to you. the only question is should all get them or only who orderd till begin of october because they have to wait so long.
What do you all think? Whatever you all want is ok.
My package is still stuck in Koln, does that mean I should get a larger refund because others have theirs and been hashing sooner. The fair answer would be no. All should get the refund regardless of when they ordered, it is the only fair way. |

How to mine Bitcoin, by hand! Keep in mind that i know is nothing practically, i wanna know how so i can make my own simple app to mine... .... PLus, any help is a help, so Thax in advance for it! i may start with CPU, since is more hard to crash the system...i hate when i have to rebook my PC  If you really want to do it then it will take you about a month with a simple calculator and quick fingers. Oh, and as you have chosen scrypt as your algorithm I take it you know you are mining LTC rather than BTC you will also need a couple of reams of paper to handle the Salsa 20,80 and the intermediary storage of 1024 strings of 128 bytes before you can begin the second set of SHA256 rounds. The easiest way is to look at a copy of scrypt.c from the cgminer source and follow the scrypt_regenhash function logic using the pure data from your example into the work->data parameter but skipping the initial big endian conversion be32enc_vect. It works out to be 16 SHA256 calculations for the SHA rounds before the Salsa, allow a day for each. 1024 x 4 Salsa 20,80 run against the 128 byte strings storing the intermediary output of each, allow a couple of weeks 11 SHA256 calculations for the SHA rounds before the Salsa, allow a day for each. All you have to do then is compare the result against the target to see if it meets the difficulty Have fun |

UPS makes me feel foolish, called them yesterday and all is fine and I will get an invoice for tax. today they stand in front of my wife and want the money cash, sorry guys tax money was not at home and they will come back in the evening or tomorrow.
But for you there is no difference because I can ship not today (on the way from a client till evening).
Keep pluggin away Chefnet, a few more days are okay. |

The dog looks a bit disappointed, like he was hoping the boxes contained something tasty, but it's just more of those damn bitcoin miners again!
That looks like a Bull Mastiff looking for something to play with, preferably a postman We used to have a couple of Old English Mastiffs, they used to love playing with the postman as well |

Not surprised really as your advert says "FREE" "GIVEAWAY" The reality is that the bitcoins may be "free" but only to use on your site. There is also no "giveaway", you have shown that in your conversation with the user, if the user wins with the 'free' money then you will not 'give' them the money, there is no "giveaway". You claim that they are stealing from you but in a US or most European courts you are the one committing the fraud because it is mandatory that a winner has to deposit money with you to get any "free" "giveaway" money. It may be that in your country, wherever that is as you have the domain ice-dice ownership hidden, ( Now, why would an honest man company do that!), it is not against the law but I doubt it. |

One sentence on http://technobit.eu/index.php?id_product=39&controller=product&id_lang=1 states Full assembled miner including PCB, 16 Bitfury chips, ....another sentence on the same page states Shipment up to 4 weeks after reciept of your chipsYour page is unclear Is the advert for A fully assembled miner with 16 bitfury chips for 461,00€ or Is the advert for the purchaser to send 16 chips to you and you will then return an assembled board for 461,00€ |
