Read the whole post I linked to. Each BIOS has a different fixed voltage, instead of variable voltage like the stock BIOS. I just use the highest (normal) voltage BIOS unless that is unstable, in which case I try the last resort BIOS. If you care about tweaking power consumption, you can try lower voltage versions (maybe work your way up until stable).
You can also grab a multi-meter, or use GPU-z and follow Stilt's info on how to calculate the ideal voltage for each card.

Word of advice: Don't just go higher with your GPU clocks, also go lower. There are sweet spots where increasing clocks actually reduces the hashrate. And no, this isn't caused by throttling.
Just go across the entire reasonable spectrum in 10 or 20 MHz steps and try everything.
This really isn't very true - it depends on the BIOS and memory timings. There is no 'ratio' that performs better, and a properly tuned BIOS will continue to improve no matter how high you push the engine clock (up until crash of course). It is true, I suppose, on certainly BIOSes that pushing the engines past a certain point will not provide benefit and may decrease hashrate, but if that's the case you should change the BIOS. |

Sorry for the confusion, it is running on a 1200 and a 750. I am thinking the 1200 can't handle it and going to test by adding another 750 I have laying around to verify the 1200's ability to provide 1080. 2700 watts should rule out any power problems. I am thinking it is a little weak when they are all at full hash. Even keeping the average I am doing, 4.55 Mh/s should be doable. I'll know in a few hours.  1200 for 3 cards and a 750 for 2 cards + mobo is more then enough. Are you using powered risers? I can run 3 off a 1000W and 2+mobo off an 850W, with heavy overclocks. |

I have not had time to test sending with the wallet but does anyone know the if there are transaction fee's with this coin, if so, what are they?
Depends on the age and size of your txouts. |

A lot of HW Errors... WTF?
I use 7950 cards. Seems like cannot put intensity on 18 like in other scrypt coins.
Something is wrong with your setup - there is nothing different about the PoW algorithm in SwansonCoin, and hashing will be identical to other scrypt coins. |

I'd like to add that I was completely wrong about my issues. I thought it was my slow CPU miners, but it can't be because as everyone else said, the diff should have just increased variance, but I switched to Middlecoin (which is locked at 1024 diff) and I'm getting no REJECTED shares. So sorry for that confusion, but I only seem to have this problem on Wafflepool, which is too bad. I've tried multiple Wafflepool servers, but just get continuous REJECTED shares. I'll keep trying, I really want to mine here. Thanks to all for the information and suggestions.
Definitely sounds like something wrong with your stratum proxy. Are you using the stratum CPU miner, or longpoll? -- @wafflepool: I would say replace the miners page with a summary of how many miners we have in various hashrate brackets. Something like: 51.2MH+: 4 miners 25.6MH-51.2MH: 6 miners 12.8MH-25.6MH: 10 miners 6.4MH-12.8MH: 30 miners 3.2MH-6.4MH: 20 miners 1.6MH-3.2MH: 20 miners 800KH-1.6MH: 200 miners 400KH-800KH: 130 miners 200KH-400KH: 150 miners 100KH-200KH: 100 miners 0-100KH/s: 100 miners Provides an interesting stats summary, whereas the current miners page has grown fairly useless except as a competition to see where you sit in the pool. |

@DaZuru: You definitely cannot run 5 of these cards on a 1200W... you would be very lucky if you can even run 4 stable for extended periods of time. I am impressed you have 5 running at all without the PSU shutting off. Add a 750W or 850W for the last 2 cards. 5MH/s is unlikely - you might manage 980KH/s on a few cards (I do have one that can pull 1.002MH at 1125 engine), but you're more likely aiming for 940 on average or so (every card is different and will take a different engine overclock before becoming unstable).
@vvar10ck: You should be able to manage over 900 with xintensity of 800-1200, 1500 memclock, and whatever engine the card can take (try 1020 and work up; or try 1080 and work down). The only disadvantage with that BIOS is that you probably can't run STILT's BIOS because you likely have a new model hynix memory onboard. (on the plus side, you definitely have hynix memory if you are on .043)

This simply isn't true. CPU mining is perfectly viable at 512 share difficulty. Share difficulty DOES NOT MATTER - it only increases variance.
It sounds to me like his stratum proxy is lagging - try pointing the miners direct to the pool and see what happens.
While my thing isn't CPU mining, a diff of 512 is giving me much higher rejects than a lower difficulty, which is obviously causing issues for me. This is not true... you will see higher variance in rejects, and possibly spikes of higher rejects, but over time it evens out no matter what the share diff. This is simply obvious - your chance to discover a block is proportional to your hashrate... shares are no different. why not mine the top three profitable coins and split hash according to difficulty.. those tiny new coins are the money but for obvious reasons the whole pool cant hit it. diversify your coin portfolio.. have eu mine something and other pool something else... wemineall can mine several coins at once so a much bigger pool should easily dobit too
PoolWaffle has clearly stated he's working on it - this requires a massive re-work of the profitability switcher. |

One of the more trusted members here should start a list of people and how much they are owed. Maybe a few people will be able to present the list if given the opportunity.
Why? MtGox will either re-brand itself and survive, and you will have a chance at getting repaid, or they will go belly-up, and then you have no chance. A list isn't going to do anything at all. |

OP misses a key thing - if they were verifying transactions by txid, and not acknowledging spends as they were confirmed, if they were confirmed under a different txid, it is entirely reasonable that MtGox failed to realize all these bitcoins were gone. It also lines up perfectly with why they had so many failed withdrawals - they were trying to spend txouts that had already been spend, but their shitty software failed to realize had been spent.

The JPN authorities won't do anything - they have clearly stated this publicly.
The only thing you can do is cross your fingers that MtGox doesn't declare bankruptcy, but instead tries to rebuild its business after a re-branding and re-organization. If they go bankrupt, you're out of luck. However, the fact that MtGox held on this long after suspending withdrawals suggests that they do intent to try to keep the business alive - so I would hold faith yet that you might see your BTC again... someday.

I think the 512 difficulty is too much for CPU mining. I ran cpuminer on 3 cores of my machine (33 kh/s total) and got work submitted after 21 mins. You may want to look at mining Primecoin (XPM). This is where I put my CPU to work: http://www.peercointalk.org/index.php?topic=485.0This simply isn't true. CPU mining is perfectly viable at 512 share difficulty. Share difficulty DOES NOT MATTER - it only increases variance. It sounds to me like his stratum proxy is lagging - try pointing the miners direct to the pool and see what happens. |

I attempted to flash the STILT bios (MBA_C6710101-100_K2_AGR_STILTMXT_V46.zip (DPM7 - 1.1125V) and got a SubsystemsID's mismatch error? What am I doing wrong? I have the 290x Sapphire Tri-x OC
Did you use -f (force) ? e.g. atiflash -p 0 filename.rom -f |

Ok, first of all check the time at which I made my post, then reply. I was talking about Feb 24
Are you really complaining about 0.00970608BTC/MH? That's pretty damn good... Look at the history in the table - daily return always goes up and down. Again, it's called variance. Man, some people I tell you... |

After running for a while. 76-78, its well ventilated
Have you tried Linux? I hated the 290s on Windows, drivers were horrible. Running four cards, waiting on a riser for the fifth. Was unstable due to me not having a couple of meters to see my power draw! Now I have a 750 and a 1200 watt power supply feeding it. Roughly 300 watts each card and 100 or so for the SSD and motherboard. It gets a little weird when I try to tweak settings but I have left it alone and running 3.64 Mh/s steady with four, hoping for 4.55 Mh/s tonight! Running around 73C with a floor fan on an open air case. Probably need to work on air flow upstairs. It is in the game room. My amateur settings: -o stratum+tcp://doge.joinaparty.com:22550 -u MYPAYOUTADDRESS -p MYPASSWORD -g 1 -w 256 --lookup-gap 2 --thread-concurrency 24550 -I 20 --gpu-engine 1022 --gpu-memclock 1500 --gpu-powertune 20 I tried the xintensity setting but it doesn't like it. Also trying P2P pool mining. Interesting concept. Connect to a node close to you. You can browse or connect to test at http://doge.joinaparty.com:22550, no guarantees I will keep it running. Trying to find the best solution for me. Daz Are these 290X or just 290s? Once you get them stable, try The Stilt's BIOS so you can drop the memclocks down to 1375 but keep the same performance, and gives you more headroom on the gpu-engine. If all of your cards run at 1500 memclock without crashing, then try pushing the engine up to 1060 - when a card goes sick, decrease only that card's engine by 10. xintensity will increase your hashrate, period. No reason not to use it. What's not to like about a way better way to tune the number of threads launched that actually lines up with your number of shaders? |

How exactly are we losing profitability against LTC if it's profit-switching? Surely it would switch to LTC if it's more profitable instead of mining lower profitable coins  I just don't see the logic there. Even if you mined only LTC, you would dip below and above expected profitability constantly. It's called variance, or luck. |
