A customer pointed out to me that he saw high rejects with the faster bitstreams, but most were rejected because they were duplicate submissions. Reducing the getwork interval got rid of this problem.
At 166 MH/s, the entire nonce range should be hashed in 25.9 seconds, so new work should be loaded before that. The default interval in the latest version on Github is 20 seconds, which should be perfect for this (better to always have fresh work then to sometimes have stale work because of a latency problem). Ah, this is probably my problem. I think I was still running at 30 seconds (the last time I did a git pull was when the submission bugfix came in). Edit: Yep, back at 2-4%. |

with the 166mhz i'm up at 19% reject rate and i'm on btcguild, I was sub 1% at 133mhz
you've at least got a fan blowing on your heatsinks, right? |

Just got done finally setting up my "mining rig".  This way they're both in front of the highest-airflow parts of the fan. Of course I'll have to take it apart again when my better heatsinks arrive, but until then it seems to be working  My reject rate skyrocketed back to 10-20% using the 150mhz and 166mhz bitstreams. This happened on both of the x6500s I tried, so I'm not understanding the 1-2% reject rate I saw on the earlier post. Maybe it's pool dependent?
Same. I'm on eligius, for what it's worth. Edit: Spoke too soon. The reject rate is higher, but not 20% high. More like 6-12%. |

Nah. What with one thing and another, I haven't had the liquidity to join in on this rally.

sweet logic where does it end
my mind is being blown right now guys

I'll be posting some pre-built bitstreams very soon, but everyone should be even more careful to monitor their cooling using these higher clocks because the potential to burn out your FPGA is much higher. Also, in my limited tests I've seen that the error rates vary from FPGA to FPGA so you'll have to experiment with your setup to see what works well for you. I've seen some FPGAs tolerate 180 MHz no problem, but others report over 10% errors at that clock rate.
In preparation for this, I'd like to reiterate my request for instructions on removing the stock heatsinks. I have a feeling my current cooling situation might be insufficient for running the new logic on my boards (especially the slightly anemic one we've discussed before), so I'd like to be ready to switch to something a little higher-end if needs be. |

Man what? There's like 50k of visible market depth to get to 6$/coin - and that's assuming that more depth won't materialize out of hidden reserves when it starts.
I mean, I hope we're going up, but a quarter million dollars of buy motion, in one day, on no news, is Fantasyland.
You are entirely mistaken. There is <25k BTC of visible market depth. There used to be <25k BTC to $5, but a formidable wall, during the last spike.  ....really? Huh. See, I usually watch bitcoincharts and they're still showing this depth graph:  No wonder I was confused! |

2012-01-04 11:11:49 | Long-poll: ValueError! No JSON object could be decoded
Maybe this has something to do with ABC Pool though? I'll try out a different pool. For what it's worth, I'm on Eligius and have not been seeing such errors. Also still getting lots of these "Golden nonce found" errors, not sure if they actually matter though? That's not an error, really. It's just an announcement by the FPGA that it's found something that it thinks is a qualifying hash. For me, at least, every such announcement is followed by an "accepted" or "rejected" indicating whether the server agrees on the matter. |

I'm pleased to report that I've located a second usable power supply in my apartment, and both my boards seem to finally be up and running. On about half of the long-poll new blocks, I see errors like this: 2012-01-03 19:36:09 | Long-poll: new block 0000094048607f5b
2012-01-03 19:36:09 | (FPGA1) Error getting work! Retrying... For what it's worth, I'm using eligius - same as the devs. |

I'm the only one who holds right now, though my brother is somewhat interested in it. As for the Christmas party... well, I talked about it while getting a ride home  Turns out my ride had already heard of it, and was thinking of playing around with it since he was already doing some GPU programming. |

228.66 MH/s | 0: 2238/210/0 8.6% | 1: 2309/227/0 9.0% | 1d21m22s
Running the 133MHz bitstreams, not sure exactly why the rate is so low. Maybe just a run of bad luck.

New problem.
I've got both my X6500 boards up and "running", but while one of them (-d 1) is returning golden nonces every few jobs, the other one has been running for ~10 minutes without a single golden nonce.
Is this expected? What could the problem be?
Edit: Had a problem with my jury-rigged power supplies and had to reload -d 1, and when I came back it was spinning its wheels too.
We need to find a solution to this kind of problem. I believe what happened was the power was removed momentarily from the FPGA. When that happens, it loses it's configuration and goes back to being an unprogrammed FPGA. The mining software doesn't know that it's unprogrammed so just keeps asking it for nonces. Of course, none ever come. We'll work on a fix to this (easy to add a bit that says, "I'm programmed" or something). Until then, if anyone gets strange problems like this, the first thing to try is restarting mine.py. The next thing is to rerun program.py. Rerunning program.py is essentially the same as rebooting the FPGA, so it should clear up any strangeness. Hmm. I suppose that'd explain it - like I said, my solutions to powering the boards are pretty seriously jury-rigged right now, so I'm not surprised that they'd cut out momentarily. I'll see if I can't get that part of the system to be more stable when I get home tonight. |

I'm having some trouble as well. Running program.py gives this error: Traceback (most recent call last):
File "program.py", line 23, in <module>

I'm on 32-bit Linux, if it matters. Edit: Bar that; solution found. Turns out there's four functions whose metadata you commented out in the modified python libraries, but you forgot to comment out the functions themselves. So it tried to link to them, and.... bang! |

But I don't get you when you say "less control in cloud computing"... Because I'll have full control of it.
Exactly. You'd have full control of it... and could run off with the coins of all your users whenever you wish |

If you mean the 5$ part, yeah. The fact that we made it from 3$ to 4$ so fast is itself pretty amazing; going from 4$ to 5$ in the 10 days we have left is really too much for anyone to hope for. If you mean the "well under 1$" part, well, I think at this point closing the year at that price is even less likely than closing above 5$. |

(Not a lawyer, this ain't legal advice, &c)
I think it depends a lot on what the definition of "payment network provider" is in this context. Seems to me that other than exchanges like Mt. Gox and the like, Bitcoin doesn't have such a thing.

Nice job beating up your straw man little girl, isn't it time for you to go jerk off in its ass? Maybe you can get enough bitcoins to buy a RealDoll someday, keep dreaming.
[...]BTW, I reserve the right to say whatever I like to a retarded child such as yourself. Sorry, you gave yourself away immediately.
You came on so strong to start with, now you just sound like a little pussy with hurt feelings. Did you stick out your tongue when you typed that? If you did, what were you hoping to find with it?
Back from dinner. Obviously you have been having fun playing with yourself while I was away. Sorry to see you couldn't keep up with the finer points, it makes you such a cranky child. BTW, is English not your first language? Is it perhaps a language without Latin or Greek roots?
I did get some good ideas from Qoheleth, enough to warrant further research and consideration. OTOH you may go back to pulling your pud, little girl, you are the most useless fuck I've talked to all day. Seriously.
I got what I wanted, it's not about you, junior. It's been easy enough to sort out the people around here who actually know something about anything from the hopeless fanboys using bitcoin to fulfill a desperate emotional need to be part of something they perceive as successful. [...] Wow, I guess you really showed me, monkeyboy. Obviously you are enjoying being a winner somewhere in your own mind, aren't you?
[...]
How did you ever get so simple minded, are you an American 12 year old on Ritalin? If either of my kids were as witless at that age as you are so proud to be, I would have had an obligation to society to either get them fixed or put them down for good. However if you are much older than 12, it raises the question of who gets you ready to be picked up by the short bus each morning. If you weren't already Sargeant Micropenis, we could call you Special Ed.
Wow. Guess this is what I get for not reading the thread fully... why did I take this guy seriously at all? |
