I'm no expert but from everything I've read when you crossfire all the cards should be the same. The problem may be adding the 5870 in and of itself. It may not be a power issue at all......

Back up your wallet.dat before updating. It should be fine, but backups never hurt. Then download new client, uninstall the old one and install the new one. That's it. Btw, geeks ARE normal people - the rest of you are a bit weird  +1  Will bitcoin.exe run if the wallet.dat file is missing? If you copy the wallet with 1 bit coin in it and then someone sends you a bit coin....should you overwrite the copy you have? Where is the data stored for the transactions in the wallet? Thx (anyone) |

I'm assuming that by "bank", you mean you've transferred the Bitcoins out of Mt. Gox back to yourself.
If that's the case, and you want to add Bitcoins to Mt. Gox, start by logging into mtgox.com. Go to the "Add Funds" page and scroll down a little to the "Add Bitcoins" section. Type in the number of coins you want to add for this single transaction and click "Send Bitcoins".
Mt. Gox will give you an address. Copy it. You'll use it once (and only once).
Go to your Bitcoin client that has the coins in it, and click "Send Coins". Paste in the address you just copied, and type in the same amount you entered on the Mt. Gox site. Now just wait a bit, and the coins will show up in your Mt. Gox account.
Thanks I was wondering that too. I set my account up but hadn't gone that far... |

"Every instance of your miner needs its own worker account"
This means i don't need to create a new worker for the second GPU, only for a second pc new worker is required, right?
Have you tried using the same credentials for both gpu's in the gui? How did that work out? Did your hash rate get halved? You need logins for each cpu. |

M'center had some crossfire cables on thier site, showed three of them. I called them and they said they had them.....
Drove an hour to get there and lo and behold there were none to be found. They said they do inventory every six months and they must have been stolen. No discount for my troubles!!
There video cards are basic. I'd be surprised if you see something above 6700 series there.

Here's what I've discovered with this problem and some of it is speculation.....
My understanding of the blkindex.dat file is that it is a data file that builds upon itself as hash's are solved.
If the process gets interfered with it seems the blkindex file gets deleted, corrupted, or becomes invalid.
I tried uninstalling and reinstalling bitcoin only to have it reproduce itself.
What I noticed was in my power settings I had never changed the defaults. The hard drive was set to shut off after 20 minutes. I am suspecting that is what caused the disconnect between the miner and the dat file.
I changed the power settings to Never shut off the display and Never shut off the hard disks......
Haven't had the problem since but it's only been a day. Considering it happened twice in an hour and it's not now, I'm hopeful.
Hope that helps.

I'm having the same issue. I also reinstalled but only to have it do it again. This is the third time now...... I'm using Kiv's gui miner......

Crashed at 256. Trying 180. So far so good. Still haven't been able to bring the second card up.

edit:
Regarding the idle miner issues:
Here's what I found: I found a Bitcoin directory in two locations. One in the roaming profile and one in C:\Program Files (x86)\Bitcoin.
When I put my bitcoin.config file in the (x86) directory and started the gui, voila!!!! It worked. I then started another gui for my second device and they both crashed
Closed them both out. Opened one gui and am currently running only one device. Need to figure out how to modify config file to get both running. Feedback?
I should also note that I had to put the following flags in or it kept crashing: -v -f30 -w256
I don't know if that's optimal but I need some sleep now. Check in later.

They were uninstalled. GUIMiner shows 2 options for mining; CPU and Cayman. I select Cayman which I assume is correct for the 6950 gpu.
Same issue with me. Been at it for hours and hours. Here's what I found: I found a Bitcoin directory in two locations. One in the roaming profile and one in C:\Program Files (x86)\Bitcoin.

So I just installed a 6950, installed ATI and OpenCL drivers. I get the same error when trying to run either GUIminer or via command line poclbm;

Any assistance is greatly appreciated!
Did you figure anything out on this? I'm getting the same issue with my 6950...... |

God help us all if all those Chinese WoW gold farmers start BTC mining I wouldn't put it past the PBC...... |

I wonder if anyone has correlated the price increases yet with the difficulty factor? Surely this will relate in some way.... |

EDIT: Thanks JJG for demonstrating my point. For the record you've been saying the same thing for a couple months now, and while you might be right in the future, you've been wrong up til now. Tell me one point in time where it made more sense to buy a 2600USD mining rig (which has costs to operate too!) than to buy 2600 USD worth of bitcoins! Theoretical mining rig(s): Caseless -- Used 5870 $175 each // 400MHash/sec; Random mobo choice -- MSI 790X-G45 AM3 $90 each new (cheaper used) // 5PCI-E slots; Cheapo 1x PCIE extenders $5 each; Corsair tx950 $150; some crap ram $20; Sempron 140 $40. There is a thread floating around somewhere about how to build a custom wood enclosure for like $30 of wood and nails that houses 5 x 2 cards very nicely. 2x above (5 5870s) = $2400. Use the last $150-$200 for some fans or something, I don't care. Hashing power of system 4GHash/sec, electricity cost estimated @ 1296kWh / month + fans, let's round it out to 1400kWh/month, locale dependent, 11cents / kWh = $154 / month. So, I can choose any point in time? Let's go with 2/18 - 4/18. Nice 2 month period of time. This is winter time so the cost of cooling will be opening a window and pointing a fan out of it to vent the hot air. To the 400 MH/s starting from 2/18: No way a 5870 would have gotten that hash rate back then, as BFI_INT was not in miners yet (as well as the phatk kernel)! Also you did not calculate potential downtime (since you slightly undersized the PSU for example at your projected electricity use of nearly 2000W per hour) + setup time. Also prices of 5870s at that point of time were likely different from 175USD. Also not included is shipping time/cost plus risk of hardware bein DoA (used!) and setup time. However thanks for that detailed overview anyways. This was a wholly theoretical exercise in mining vs buying as a response to someone. I chose numbers to most benefit my argument, and I said so from the start. However it was pretty close so as to be relevant, there is no point in taking shipping / building time into account, as the idea was to begin mining on the same date as buying coins, not start buying equipment. The chances of DoA equipment is irrelevant. DoA rates are negligble. I've been continually buying 5870s for < $180 for the past month, there was a sale from newegg about 2 or 3 months ago for 5870 2GB models for $180. It's not at all that much of a stretch. A 5870 gets between 430 - 440MHash/sec right now with BFI_INT and phatk, 400Mhash with a good overclock is reasonable. 2000Watts (per hour doesnt mean anything) is overkill on electricty. I run 3x5870s on < 600Watts right now overclocked, so my numbers were fine. Anyway, small things aside, the soundness of the argument stands. When bitcoins price remains relatively stable, difficulty does not increase that much, and mining is superior to buying coins. When bitcoins price explodes obviously having bought a coin the day before is better. But no one can know the future. As Litt says, he wishes he had bought a buncha coins instead of buying mining equipment. Why didn't he? Because he couldn't predict the future. No one knew that bitcoin was going to explode from $1 / BTC to $11 / BTC in a matter of 2 months. It might have stagnated forever. And it might continue to rise or it might plummet like a rock, in which case buying coins is far far far stupider than buying mining equipment. My only argument from the start has been that you don't know the future, so speculating that one approach or the other is better is irrelevant. You can guess as to what you think might happen, and plan accordingly, and that's the best you can do. But don't tell people that it will definitely be this way or that. I guess some people are missing the point that some people may just REALLY enjoy the mining experience. That variable cannot be measured. I always tell people I can't get into golf because I would spend too much time and money on something I don't fine value in. Some guys look at me crosseyed because they enjoy it so much. Same with skiing, water or snow or any other damn sport for that matter. Personally I view people trying to convince others to just by bitcoins similarly to people who try to get others to believe their religion. They feel better if they can win converts. They're burned out on mining....maybe weren't that good with hardware or would just really rather be doing something else. Which is perfectly fine. But on and on with it these people!! The way I do math, you can't lose mining. And I will not debate it with anyone. Cheers |

I like what your proposing. I've been looking into it now for a couple hours. It really does seem to make sense. Put my shopping list together.... |

If a pool grows over 50% we should DDoS the shit out of it.
It's basically our only weapon...
That's against the spirit of Bitcoin. Bitcoin is a capitalist market. He who holds the most riches has the best chance at profit. He who has the most power has the best chance at profit. Isn't capitalist also democratic? If it would jeopardize the sake of the community for profit, isn't that the current regime we are living under? Just thoughts.... |

All you have to do is google it and click the cache link instead of the main link.

Now it does not seem that on slush's site you can change your login password....at least as far as I've seen.
You can, use link on login page. Obviously certain pool members in slush's pool are thieves.
Pretty strong claim. Why necessary *members*? Login page is open for anybody and you used weak password. So be careful. It might worth paying a higher commission somewhere else
You don't need to pay higher commissions somewhere else. You have to setup stronger password. Please don't spread FUDs. All true. Apologies. I removed the post. |

The theory of "just buy coins" continues to crack me up. Where will they come from?
As long as difficulty is above 1, this means a new block is being generated ~every 10 minutes (for this you need far less than a singe GPU miner worldwide). What do you mean by that exactly? Are you saying it doesn't matter how many miners or gpu's you have cranking? |
