whats a used 5970 worth, unmined one?
I recentley paid 250€ for one, with fairly little usage reported and condition that suggested nothing othervise, this is in Finland where 23% of the price is made up of taxes, so an untaxed usd price for comparison at todays exchage rates would be about 262$. I considered the price I got good and bought two units. |

I applied the "fix", the rig nolonger randomly loses connetion, or if it does it's able to regain it. WOOHOO. However it does not resume mining when this problem occurs, so Im having trouble seeing the benefits here : / I'll toss in 5btc to actually fix this issue, paid when my problem rig has been up for 120 consecutive hours. Others with the problem feel free to chip in. |

BAMT 0.5 sometimes lost network, i don't know why. 0.4 bamt works well, but i can't find fixes for it
Good to know some are having the same problem. I have 5 completely different board that have this same problem, I found out it would often happen exactly after 10hrs. try my solution and let me know your result. i've done it 20 times it always works on 0.5c: http://www.bitcointrading.com/forum/index.php?topic=416.msg1235#msg1235Thank you, im fairly sure this was the issue I was struggling with a page or so back in this thread. It would seem like a reinstall of bamt cleared the problem for some time, had a stable 30+h after it, so this (in my limited understanding) could perhaps be something accumulating on the usb-drive over time ? |

Im experiencing an awful amount of orphans: Shares 185 <17 orphan, 3 dead>. I only have 10 open connections to th network as my Ip changed, I do have the ports forwarded but usually takes me 2 or so days to see more connections. Can this orphan amount be considered as normal or within variance ?

What if BTC exchange rate doubled when the block reward drops? Nothing happened?
That would be sweet, but I try not to make mining assumptions based on wishful thinking. Tbh my pessimistic projection for next year is an average difficulty of 1560000 (10% lower than current) and an average exchnage rate of 6$. The only function of these numbers to me is that I need every single piece of hardware I mine to be profitable at those conditions, or it gets unplugged and sold at some point. |

Is there any way to identify which rig, or even better which gpu is responsible for my orphans/stales ?

Funny, I just tried this yesterday with my 5850s. I've been running at 0.95 and took them down to 0.90. In my case, at least, the reduction in power consumption wasn't very significant. Sorry, I don't remember the exact difference, but I think it was less than 15w for the four 5850s in my rig. Anyway, I decided not to bother with it and stay at 0.95. But the cards were stable at 0.90 during the time I played around with it, and I took them up to 725MHz, just 25MHz below the core clock I normally use at 0.95. I use atitweak (linux) to set the voltage if you are wondering.
Since I see myself facing a situation where I'd prefer to "run my gpu's to the ground" I find myself looking for the utter optimal MHS/W, in advance for the upcoming block-reward drop. It can also be the more profitable way to go for me, 5970 2nd hand markets seem to be getting active around here, most likeley because of new models hitting the market and I fear the situation might get rediculous around the block-reward drop. Personally if I had free electricity I'd make damn sure to have liquidity to invest in to gpu's when the block reward gets chopped down. |

I've been betting on the world ice hockey champinships also, everything has worked smooth. More smooth than the five or so other sportsbooks I've used in the past. A big part of this "smoothness" is ofcourse in bitcoins speed. I've been brave enough to slip about 50 of my hard earned bitcoins on to the site and I have not been ripped off. I have caught a few glitches on the site, but nothing major, mainly just some explanatory "something has failed in generating this page" type of message. Which passed in some time, overall Im loving it and the gameselection they offer is propably the largest I've seen.

Good timing with the promotion a 15% difficulty increase means it's grow or die tie for small and mid-sized pools.

Been having some hardom crashes lateley, there not due to overclocking. I found this in in my syslog: May 8 13:36:18 (none) mother[3490]: #011autoconf client doesn't seem to be running, spawning one

May 8 13:41:01 (none) /USR/SBIN/CRON[4107]: (root) CMD (/opt/bamt/mother)
anything wrong in there ? [Edit] the other clues are: Rig stops mining, ssh-connections close and new ones cannot be made. The rig nolonger responds to ping. The rig draws ~200W instead of the ~600 when it's mining. Im propably looking at a random network issue here, but I have 3 other machines plugged to the same router in a similiar way and this is the only one acting up. |

Amazing. Switched over from Deepbit. This pays more and is overall much better. I love the client too!  Thank you for such an amazing pool. Welcome, do spread the word, we could use a couple more 100Ghs to lower varaiance. |

Nice catch, watching closeley.

I personally "do math" every 1800 blocks and whenever the exchange rate moves over 15%. I have to, when electricity rolls in at 0,17$ there arent that large margins involved.

Once you join the dark side, you can't go back.  But yeah, Ztex is a good candidate, I think there are quite a few of those boards out there. Also you should keep an eye out for Lancelot that is currently under development by ngzhang, I believe he's first, now discontinued board icarus still remains the best selling fgpa to date. |
|
|
|
Any other FPGA products that I should add support for?
Ztex-boards seem to be building up at my neck of the woods (Finland), I for one havent bought any, the price seems too high to me. They also sell discounted boards to any open-source devs, incase you are interested in switching over to the "light side"  |

I just ordered some Crainsmore Quad XC6SLX150 Boards, this could be an opportunity for bitminer to snag some serious MHS should you be able to provide support in the bitminter-client. I'll be willing to run mine for testing ofc and Im fairly sure other ppl ordering these might stick with an easy to use miner available early on. I have no idea on what goes in to making a new fgpa work in your client, but once I have mine I'll help in any way I can, should the good doctor choose to take this opportunity up. All the current info available on the boards (that I know of) is located at: https://bitcointalk.org/index.php?topic=78239.0 |

Difficulty seems to be on a steady rise, is "it" back ?

Lets skip the first two rules of fight club, mkay ?
Howmuch are we charging for shares atm ?
Is there any public work atm ? I tried as low as 0.00002999 to make sure.

I just noticed that one of my rigs that is running cgminer keeps tossing about 20% of it's shares to a backup pool.
"Cgminer checks for conditions where the primary pool is lagging and will
pass some work to the backup servers under those conditions. The reason for
doing this is to try its absolute best to keep the GPUs working on something
useful and not risk idle periods. You can disable this behaviour with the
option --failover-only."
Pinging mint.bitminter.com gives me an average reply time of 53ms, this shouldnt affect things right ?
Im pretty sure there is no lag worth mentioning between me and mint.bitminter.com.
Could someone else running cgminer check to see if this is going on at their end too ?
[edit] looks like this is a bug in cgminer that can be "fixed" with running it with the "--failover-only" option
