860-940 here, 6 5850's.
900 isn't a sucky card, it's average.
At least for me, 5850's run at a lower voltage (1088mV) than 5870's (1163mV), so it's not surprising that they don't clock as high really.
Seems like my card is normal then. 5870 run at a higher voltage because they have more SIMDs, TMUs and shaders. |

Has anyone been able to get 5 or more GPUs to boot in Windows using 12.1 drivers or newer?
I have a 7 GPU rig running 11.12, but as soon as I tried 12.1 I got BSOD on every boot. I was wondering if anyone had been able to get more than 5 GPUs to run stable on the 12.x drivers, as the new 7xxx series requires these drivers. Reason I ask was because I was thinking about building a rig with 7 7850s when they come out...
I couldn't even mine or browse the web for more than 10s without BSODs after adding 5th GPU on 12.1. Tried everything even hot-plugging the GPUs. Returning to 11.12 fixed the problem. |

Simple economics my friend. The only joke around here will be the people criticizing it whilst they could have bought it for $0.05 and sold it for $1-4. But since that won't be happening for a few months I guess we'll have to wait a bit for that punchline  QFT |

Just started mining and have my two 5870's running at 900/600 with temps at 71. Not looking to push them too much.  Im running mine @ 1005/320 with same temp and fan at 65%. Stock voltage, you could try at least 970/350 |

I don't know how much cryptoxchange is involved but whomever's account sold the coins is a good spot to start the investigation. There are posts all over the forum about the stolen BTC and where a good portion are right now.
An investigation that would lead to what exactly? If he used his own pc without tor or proxy or used the account for usd deposits/withdrawals, locating him might be possible. |

Thanks for answering. I could access it with vi and emacs.. but when I tried with nano, it created a new file and I couldn't save it ('file doesn't exist' or sth like that msg). When I plugged the key to my windows rig to edit it from there and saved the changes, only some of the changes are saved when bamt boots. So I'll give a try with a new key. |

I made some syntax mistake in the bamt.conf file and the gpumon doesn't start (I get that funny error message), so I wanted to edit the file at etc/bamt/bamt.conf but.. why do I have writing permission disabled? I'm logged as a root and did not change any permissions, only thing I did was set a password. Any ideas?

So I bought a referent HD 5850 1 GB recently, I can only overclock it to 900 MHz gpu core, anything above and it will crash (using BAMT), memory clocks do not affect it, tried 190, 300 and 450, when I raised the gpu core clock to 925 the card only submitted 5 shares before crashing. At 910 same thing happens, at 900 it is 24/7 stable, GPU temperature is aroung 60C with 45% fan.
All my other 5850s (non-referent, sapphire, sapphire extreme, etc.) are stable at 945-960 with stock voltage.
Am I the only one with such a sucky card?

I have had baked cards run for years, it is a combination of random and the number of hot cold cycles, best bet IMO is to run your stuff 24-7-365
Well I doubt it would last that long with GF8800 cards ;-) Also with those that are lead-free. |

I have a GA-965-S3 board, used to run 3 cards with non-powered extenders with some overclocking on bamt but without overvolting. Cards were 5830 and 2x 5870. Later I changed 5830 with a 5850, 2 cards were on PCIe x1-x1 12cm extender, one was in PCIe x16 slot. Few days ago I added added a 5830 so there were 4 GPUs in total, one for each slot (3x PCIe x1, 1x PCIe x16). PSU is a Tagan mid-range 1kW unit. Yesterday or so, bamt started to lock up as soon as mining started, I checked the ram and cpu on another mobo and they were fine, also, they aren't overheating. Without a card in that slot the rig mines without any problems, I tried a few GPUs in it and I can hear BIOS beep indicating the mobo starts but no display output whatsoever ('no signal detected'). If I remember correctly the mobo would even load an OS with that card and I could connect via SSH but the rig crashed or didn't detect any card in that slot. Now nothing will happen, even the BIOS won't POST, I can use use other slots though and connect a monitor to any of the cards, all three PCIe x1 are fine for both display output and mining. I looked carefully at the board, the are no burn marks or leaking (or 'fat') capacitors, tomorrow I'll give a look at the back of the board. I think it is possible to (de)solder those slots but I don't know how difficult it is to desolder the old one and solder in a new one (2*82 pin with an ejector: e.g. http://www.te.com/catalog/bin/TE.Connect?C=11535&M=FEAT&P=71680&U=&BML=10576,17560,17536,17751&LG=1 ) Or how much time does it take, is it worth paying someone more experienced (I'm clumsy at soldering). I'm not entirely sure the 4th GPU should do that (yeah, no powered extenders but 4 isn't much), on the other hand, there was only a 4 pin additional power connector on that mobo. TL;DR: Any advice on replacing a possibly dead PCIe x16 164pin slot? Or maybe there is something else I could look at, I am not 100% sure the problem doesn't lie somewhere else within the motherboard, maybe it's the mobo's VRM? Anything to measure? Advice is welcome here.  |

Wow. I was just about to buy at least 3-5 when I saw his offers on bitmit.net and on the forum. Upon asking if for escrow I got a response that he has never used it and don't know how it exactly works so I explained it to him and gave him some examples (reputable forum members, btcrow, there's escrow on bitmit, etc.). After that he never responded so I decided the price is too good to be true and to risk.
I hope those of you who got scammed will get their money or btc back, even if you don't succeed with police/court and know where he lives, pay him a visit.

As with sex, mining is not done "best" at the fastest speed.
Overvolting uses considerably more power and makes any extra MH/s gained wasted because it cost you considerably more in electricity to get them. Not to mention the additional heat, noise, and wear and tear on your rig. The 6870 is also a terrible mining card (loud, hot, and slow). Sell it on eBay and buy a 5870. You will not regret it.

Two year customer last month, never had problems but I've been around the Bitcoin community long enough to be suspicious of people who "lose" bitcoins or have them "stolen"
Normally I would agree with you but in this case Slush (and Zhoutong who's btc also were stolen) said they will cover the losses out of their own pocket. |

The Linode's user agreement says, "no".
That doesn't mean they Linode can't be sued and forced to reimburse the losses. |

I an guessing that vanity names will explode in usage after the reward block halves, since Bitcoin mining will be very unprofitable at that point, and there will be a lot of hashing hardware sitting idle. I recently decided to focus on mining while I can, and put my vanity name generation off until next year.
The difficulty:price ratio will also change and only that's important (apart from maybe liquidity on exchanges). |

EULA's aren't the end-all that companies make them out to be though. Even if they say "we will not be held liable for blah blah blah", doesn't mean that a court won't hold them liable.

I was just after getting off the phone with the organisers, the videos will be available on the TED website in about 2 weeks.
He tells me that my talk went ok, guess I'm my own worse critic.
I've got a few notes of the Leeds Ludos, I didn't want to spend them, they look too nice, I'll get a pic of them up later today.
Nefario.
A lot of people have such problems so don't worry, I do too, you can join a Toastmasters club if you have one around in your area, there is 13 000 of them around the world, it really helps with speaking in public/learning to make speeches/improvising, etc. |

I'm under impression, you are the first (or one of the very few) people who were hacked and decide to cover the loss from their own pocket. Now I'm happy we have at least the 2%. So we can see that all linode bitcoin users were affected - if I were you I would contact everyone else affected and send a letter to the company demanding to cover the losses or have a class action lawsuit. At least that's what I would do but I am not a lawyer/what's their ToS/on what terms you were using their service,etc, but I wish you good luck. |

The shaders were unlocked and not 6970 bios if that was implied anywhere. They were homebrewed bios but a couple dozen people at least have used them fine for as long as I have. The card was originally not the best card. So I am pretty sure it was the combination of bad card unlocked shaders and mining 24/7. Very few problems are so simple as to be 1 cause.
Do you know what was changed exactly in that bios? Also what were the VRM temperatures? |

I got 'boot disk failure' while POSTing message upon restart, does that mean my pendrive is already dying? I reinserted it and pressed enter and it's fine but I'm not sure if this is not gonna repeat when I am away and a GPU locks up.
So it's not actually related to BAMT but I'm really interested how long can a decent pendrive last (I'm using an 8GB QPI)
