First problem: I am having some weird bitcoin problem, I reinstalled (downloaded newested bitcoin from bitcoin.org).  Second problem: I get "Verification failed, check hardware!" for my GPUMINER. Why does it do this? specs: win 7 64 bit 4 GB RAM 6970 ATI PowerColor (new card i just got that gives me this error) quad core 2/4 ghz psu 750w 880 core clock 1375 downed to 1200 (lowering to 800 only decrements temp for me by 1-4 c) and makes pc way lagger -f0 -d0 -w 128 are my flags when im sleeping i put it to -f60 when awake for now my problem 2 i use the console now and coded a program which kills poclbm after some time and then runs it again like every 30 mins.

Setting: Value when sleeping (Value when awake)
Voltage: 1.2
Fan: 50% (55%)
Clock: 925
Frames: 0 (60)
Memory: 800
-v slowed my pc
-s0.01 lowered my average hash rate by only 1-3MH/s, but its a good feature to use i guess when sleeping but I don't use it I might later on
-w128 worked wonders
-w64 froze my pc about 2 times when i did stuff on my pc
-f 0 works good and doesn't lag my pc too much i can still go on forums, etc.
-f 60 works better when i want to use my pc
Temp never go above 74, but its on [71-72] average.
I was wondering why when I went to youtube my computer would freeze also if someone could be so kind.

Should I use GUI miner/poclbm or phoneix, I don't want to overclock my gpu too much cause I want to run it 24/7 and I don't want to hear my fan noise when Im sleeping (I sleep 1 room away and I keep the computer room closed and yes it has a return duct for intake). Hope someone can help me out.

Not too sure about that PSU, and why not get a 3 slot mobo so in the future you can hook up another GPU?
Good luck.

When i use the console/dos version to mine i dont get that error...

450watts is what you draw from the wall then it has to be converted to dc power considerable power loss between the 2. Consider the following any usb deices and so forth take power another thing to look into is was there a beep when ur card failed? try over clocking till your computer shuts off. Listen to the beep patern from the mother board watch how many long and short bees then google it. Chance is that its lack of power could be other stuff thogh good luck

not sure if buying BTCs for 5000$ would be better investment.
If you buy the hardware and bitcoin's value should crash, you still have the hardware  yes i agree to this, but you should still invest in btc like $200 to $500 if you can afford it. |

I'm so jealous, if I knew about bitcoins about 1-2 months ago I would have bought $1000 worth of BTC and then I would sell it now... I would be making 7 grand in just 2 months.

A unlocked 6950 would be the best. Or a used 5870 if you can find one.
Go for a 5870 new, if not then a used one. Make sure your using a custom fan, not STOCK. edit: 2x 80mm (or bigger) fans minimum would be good... 3 would be better |

Well i decided to turn off my pc for one night after 1 week running it straight on 65% fan speed (around 62 C stable). Then I wake up, and turn on my pc and I hear this like rickety noise... im like WTF! I then find out its my GFX so i pull it out and clean off some dust (yeah my pc got a lot of dust this month...) I put it back, still making that LOUD ASS noise.. im like shit.. now i need to change my GFX... but then i touch the fan slightly (pushing it) and it stopped making that noise.... so im wondering should i go and do this with my new 5870 or is mining not profitable? and how long do your cards last on maximum usage, 60-70% fan, and around 55 C to 62 C.

I have heard of people using a sempron for their 4 gpu rigs. I think it will be fine using that setup, but if you are planning on doing any gaming or anything else at all I advise a phenomII x4(or wait for bulldozer but then mining won't be as profitable).
Processing power is required to move data around and do instructions, those instructions and data being moved around are done in the GPU... now let us BOTH think what happens when your CPU can't keep up with the GPU in some (i said some) respect? Obviously the GPU is and will always be better, BUT it doesn't mean you put a $10 single core with a $700 GFX and expect perfect results. If your going to do that at least get a duo with 3 ghz or quad with 3 ghz or even a 6 core if you plan to go for the 2x 6990s... |

I suggest getting a better cpu unless you want to get held back and lose performance in mining. Also, I suggest getting 4x pci 2.1 mobo with 5870's or stick with the 5970's or go for the 6990 and stick with the mobo.

Purchasing BTC at a reasonable rate. Contact me (email) at psknives@gmail.comI buy and sell with trusted members only or somewhat trusted if in a low amount. Maximum sell/buy is $50 for trusted and for somewhat trusted it is $10 for first transaction. |

This is what I have sent them, but I have not received a reply yet. I sent this on May 5. |

You can't know who it's profitable for, or it isn't. Mining was never profitable for me, and in general I don't, but I can envision conditions that I would mine for short terms. There are many users who mine in their winter months because the cost of electric is either the main method of heat, and therefore running a miner is just a possible bonus to paying the heat bill; or they functionally have near free electric.
If heating is a non-trivial part of your electric expenses then you should be using gas (much power cost per therm than electric heating), and/or an electric heat pump (greater than 100% "efficiency"). Because of this, even with heating as a consideration mining will never be free, unless you can make some sucker pay for it for you.  Generally in GTA, Ontario, Canada you can find apartments around $800 to $1400 (depending on size and rooms) with free utilities (some not all). |

Already with under 40,000 users we are getting weird spikes on the market and difficulty. When do you think that the difficulty would rise so much that even a 6990 won't be getting barely anything.

I am assuming thats prob one of the best crossfire options... but i know i got to get some HEAVY cooling done or else its going get blazing hot.
