So I got a few friends of mine involved in bitcoin mining... convinced them to buy a few 5830 GPUs since we can get them for about $110 USD each up here in Canada.
I noticed that when installing ubuntu with these 5830s at any clock setting (stock or overclocked) the mouse didn't show up. With or without fglrx drivers... no mouse... hrmmm???
I have managed to set the memory clock to 300 MHz and the GPU core to 975 MHz with no problems and have received about 240 MHash/sec off of each card. I was hoping for at least 250 though.. :S
Any suggestions to up the speed?
Not to take the p_ss out of your question  but you could get that extra 10mhash from mining your cpu(if its atleast semi decent one) Just make sure if you mine GPU/CPU together to leave one thread open so that it wont cause a slowdown on the GPU. Might be a windows things but worth checking first on linux. No offense taken! My buddy is running 4 * 5830s on an MSI 790FX-GD70 board... works fairly well at the moment... doing about 20% better than stock speeds at only ~18% gpu core increase. Really my question is "is there a limit to how many mhz a cpu core can acheive? or is it solely dependant on temperature?"...  I will be playing around with them more over the next few days and will let y'all know. As of right now... we're doing almost 1 Ghps on an $800 USD rig. PM me for parts/info. The speed the core can handle is partially dependent on the voltage it can handle. Those are easier to discover in windows than in linux. The wiki says VECTORS BFI_INT FASTLOOP=false AGGRESSION=12 WORKSIZE=256 so no different that a 5850 or 5870. |

I've contacted ufasoft for some assistance in getting the compatibility with his miner fixed.
In other news, we crossed 100 gH/sec a while ago, and are still seeing a steady rise. The new hardware is having no issues handling this additional load based off the reports in the IRC channel.
Many updates will be going live in the next 48 hours now that my attention is allowed to move from scaling/hardware to software updates.
Hopefully more speed will minimize the variance some and make for shorter rounds, because it's making my payments smaller even though I just increased my hashing rate.  sure. bigger pool size==better efficiency/stable load. Theoretically yes, in actuality, not all the time. Even deepbit has been getting 1 hour long sessions before getting a solve, and that's at 1 Th/s. Simple math would say that a 10 hr block @ 100 GH/s would be acceptable, when I think a lot of people would get frustrated if it went that long and some would hop over to another pool. |

I'm pretty new to this whole deal. My friend got my started on it today. Essentially my issue is that I'm running 2 4890's and they over heat after running GUIMiner for about 20 minutes. I've ramped up the fan speed to no avail. They still over heat and the system crashes. I'm assuming this isn't normal seeing as how some people run systems 24/7 and successfully make a little money. I've never had any issues with these cards over heating what so ever in any other circumstances. I am running them in CrossFire, but it seems to be the only way to get it to use both cards. If it isn't running in CrossFire, then it will only work at the speed of having just one card running. Even with just running on one card, it still over heats the card. Any suggestions? I'd really like this deal to pay for a new set of video cards. lol
Cards need a lot of airflow. If they are spaced at least 1 slot apart then you need more ventilation in your case, try leaving the case open for starters. If they are right next to each other, try folding some paper and wedging it between the cards to open up more space for airflow. |

"Don't Take Your Bitcoins To Heaven, Heaven Knows We Need Them Here"
To my Christian friends,
Glorious times are upon you! You must all be anxious and enthusiastic that the Rapture is upon you. Although I do not believe as you do, I wholeheartedly believe in Freedom of Religion and Freedom of Worship and I am very excited for you. I am starting a new service, Rapture Services, LLC.
Do you have friends or family who's mortal soul you are worried about? What happens if one of your friends or family is not taken in Rapture and left behind to face the End Times? Why not leave them your Bitcoins to make their life a little easier? It works like this. You contact me via private message and I will give you a Bitcoin address to transfer all your coins to me. Each person will have their own individual address so that there will not be any question as to how many coins were shipped to me. I will keep the coins safe by copying the wallet.dat files to as many different media types as possible and take all possible including safes, faraday cages, and faraday cages in safes. I will provide you contact detail including Name, Physical Mailing Address, Home Phone Number, Cell Phone Number, and E-mail addresses on all major e-mail providers (Hotmail, Yahoo, Google), and HAM Radio ID in case of global communications disruptions. You will include my information in your final correspondents to your friends and loved ones before the Rapture with directions to contact me if you are taken in Rapture and they are not. I will allow one week for people to contact me then distribute your Bitcoins to them evenly unless you leave more detailed instructions about how to distribute them. If you, yourself, are not taken in Rapture, you can contact me directly and identify yourself via and agreed upon identification mechanism and I will transfer your Bitcoins back to you directly. I am willing to provide this service without any fees to you or your friends in light of these glorious times.
Maybe you are a lonely soul but what about your pets? I am also offering pet sitting services after the Rapture. Transfer me your Bitcoins as stated above and I will give you my address to ships your pet to me. I will keep them here at my ranch where they will be happy and free to roam and play with other animals until the End Times. Ask about my Noah's Ark discount (Note: pets do need to be male and female to receive the Noah's Ark discount).
Thank You and Have a Blessed Rapture.

Did you ever connect to Eliguis (Luke-Jr's) pool. It doesn't usually distribute payments < 1 BTC unless you haven't connected in which case it will payout whatever is left in your account.
Other than that it could be someone transposed a character in their bitcoin address and it happens to match yours.
Or it could be a bitcoin address clash even though the possibility is statistically minute.
EDIT: Doesn't distribute payments < 1 BTC unless you haven't connected for a week or more.

The counter for m/hash on your website seems to be off a bit for my workers. worker1 on my PC is at anywhere from 520-590 m/hash, but on the site it shows that its between 200-590 m/hash, and consistently says its at 350 m/hash or below.
That's because your workers don't return work at a consistent rate. Look at the column that says Last Share. Some getworks take longer than others to process, so the math is constantly changing trying to calculate it. Once you've been running for a while your Total Worker Speed should be roughly correct and that's all that matters. |

What problem does it solve exactly?
If you're still communicating with a remote server and doing shared work and the server goes down, how is it any different than the current scheme? You won't be able to communicate with the server to submit work and all client will basically be orphaned.

I am fairly certain it has to do purely with temperatures now guys...
I tweaked the cards a bit to guarantee their temps stayed below 75 celcius and the rig ran fine overnight.
If any one of the cards rises above 85-90 for too long though this seems to happen :S
I thought GPUs were smart enough to automatically shut off after getting too hot?!
What GPU's are they? When I first got mine and they were pushing 80 C I started getting worried about temps so I searched for it and from what I found, most 5850's internal cutoff doesn't trigger until 100 C or more even though it is generally recommended to keep them below 80 C. |

All work is done locally ...
1) If you're doing all the work local then why bother sending it to a pool?
2) Why should the pool trust the number of shares you worked on? Hack the bitcoin program so that your Pentium III reports the same shares processed as the guy with 5 GH/s.

Bump  Can someone advise me on the types & amount of risers/adaptors I need to get 4x gpus working on this mobo? Thanks. As far as I can tell you don't need any risers. Don't screw the cards in tightly and use something to wedge them apart so they get better airflow. Your power supply only has 6 PCI-E connectors so you will need 2 Molex to PCI-E connectors if they don't come with the video cards. http://www.newegg.com/Product/Product.aspx?Item=N82E16812201004&cm_re=PCI-E-_-12-201-004-_-Product |

As is the standard, the server decided to wait until a few hours after I was asleep, but a few hours before I would wake up to die. I did not have time before work to diagnose what happened, all I know is that the server was not responding to connections, even SSH from the internal network. I did a hard boot and restarted the server processes.
Last I saw before it went down it was in the 90 Gh/s range. My Estimated Rewards correlated to that. Database and/or bitcoind logging overload? Not sure why it would lock up the rest of the system unless there was a memory leak introduced somewhere in the upgrades or temp/log files were eating up a lot of hard drive space. New hardware is always awesome but almost almost always causes it's own problems. |

Its strange that the pool goes down without any warning...
The hardware broke?
Maybe he blew a breaker? lol |

I left a rig of 6 video cards running poclbm on ubuntu 11.04 overnight and everything went fine...
I left the same rig running all day today and found that my mouse was "jittering" in the lower right side of the desktop, the desktop was still visible, presumably active... but my mouse was frozen to a section of the screen and the miner terminals seem to have stopped working (not updating anymore).
Any solutions for this?
Does anybody even know what's causing it?
Could it be their temperatures? Some cards are approaching 80-85 celcius when mining... perhaps just heat adding up near the rig over time?
The mouse moving around by itself shouldn't freak X out. Are you running Ubuntu 11.04? I saw something about turning off multiple desktops or if the mouse hits the edge of the screen it will flip desktops and impact mining. If it's a usb mouse, just unplug it and see if that makes any difference. It's more likely heat, power, or the fglrx driver freaking out. |

Quad crossfire 5970's with a Sempron 140 and 1gb of RAM?
Are you serious?
At least put an i7 in that system. Go with Sandy Bridge even or wait for Ivy.
Total waste of money to buy an i7, UNLESS your going to use it to game. Sempron 140 is fine. I'd say get 2GB of RAM though, as when I was shopping it was like $20 for 1GB and $25 for 2GB. So if I go for minimal cost no future expansion it'll look something like this GPU: 2x 5970 ($808) MOBO: Foxconn A7DA-S 3.0 ($45) CPU: Sempron 140 ($39) PSU: Diablotek PHD ($70) RAM: 1 GB Lying Around ($0) HDD: None/USB ($0) CASE: None/Cheapassjunk (~$20) OS: Linux Ubuntu ($0) $982 for ~1.3 Ghash/s [1.324 Mhash/$] Not sure about the power consumption but it cost $0.20/kWh So if I wanna go for more GPU then I'll need more PCIe2.0x16 slots? or what other slots? The PSU and MOBO with >3 of these slots are much more expensive though I wonder if it's more cost effective to just build another similar machine. P.S 140.285714 BTC to breakeven. Can someone tell me how long it takes to get this amount of BTC I already have a 140 MHash/s so total is around 1.5 Ghash/s if I build this. And if I should continue to mine in pool and at which point should I start mining solo? Hmm Mobo doesn't support Sempon: I would recommend this http://www.newegg.com/Product/Product.aspx?Item=N82E16813130290PSU has really bad reviews: I would recommend this one http://www.newegg.com/Product/Product.aspx?Item=N82E16817152043Memory needs to be at least DDR3 1033. You probably don't have they laying around if your computer is 9 years old. http://www.newegg.com/Product/Product.aspx?Item=N82E16820148147Buying the cheapest parts invites trouble. Spend as little as possible but make sure you're buying quality parts. Yes it DOES support the sempron. I run a Sempron 140 in mine, no problems... I have that same Foxconn board. Newegg only list Phenom as supported processor, I thought it was kind of weird but ok. |

What does it mean when it says this PCI Express 2.0 x16: 2 ( x16, x4) is this alright? Cuz if it then would this mobo work too? Looks very much the same but cheaper. And this PSU have great reviews too though it's not Gold but it's 80 Ready which actually I don't really know what's the difference -.- Yes I'm trying to skim course USD is a larger currency than mine, every 10 bux difference helps. Would you be kind enough to tell me if those work too? and if so, what's the difference? For 1 GB DDR3 probably someone I know would have one lying around haha. Everyone's been going 4~8 GB I'm sure there are plenty of 1 GBs around X16, x8, and x4 are speeds of the PCI Express slot. That doesn't matter for mining. That board would work, but it puts the cards right next to each other and doesn't allow much room for airflow. Something you should avoid with 5970's especially. You should also ask friends, family, and co workers what computer part sites are available in your region. Upwards of 90% of computer parts in the US come from the Asian continent. There has to be someplace in your region that you can get stuff from, possibly at cheaper prices. Depending on what currency you are using, you may get better exchange rates buying in Euros or Australian Dollars. You would very likely get better shipping from Australia than the US. |
