I would give Ubuntu a try, beats the $hit out of M$ IMO. I can walk you through a mining configuration if you choose to do that.
That's simply not true. I've tried mining on Windows 2003 x86/x64, Windows Vista x86, Windows 7 x64, Mac OS X 10.6.8, RHEL, CentOS and Ububtu. I've noticed no correlation between OS and speed. Though I've noticed straight correlation between mining speed and straightness of the hands ; ) Oh, and Mac OS X just sucks ; ) |

Oky dokes, I've done that and it seems to be working off the GPU now. Progress! Thanks!
However, it doesn't seem to be processing anything though. The GPU is under load, but I'm getting now kH/s results and it keeps on rejecting blocks.
Now you need to optimize cgminer setup for your card. F.e. add to parameters -w 128 or -w 64 or -w 256 -v or -v 1 or -v 1,1 -I 7 or -I 10 Find the best for your card and run ; ) |

I have no idea what you just said  1) Open notepad 2) Write there cgminer.exe --url http://api.bitcoin.cz:8332 -u YOUR_USER -p YOUR_PASSWORD pause 3) File->Save As-> Locate to the folder where your cgminer.exe is located -> Save as "start_cgminer.cmd" 4) Close notepad 5) Launch "start_cgminer.cmd" |

Anyway, it is pretty much impossible to compete with ASICs using GPUs.
With loads of these on the market, would the GPU's keep mining along at their current performance rate? btc or ltc per day. Or will the actual amount mined per day be expected to drop? Ofc it will drop. Pretty easy to check - count all Avalon ASICs, multiply by performance, add this value to current BTC hashing rate, compute new difficulty(f.e. here - http://www.kaptain.me/btc_calc.php), check how much GPU will earn per day at this difficulty. Thanks, that's what I figured. Interesting conundrum  However.. more ASICs = more overall Bitcoin hasrate = more trust in Bitcoin = more USD per BTC = more profit for everyone, including GPUs ; ) So you are saying GPUs will still get to mine at least "some" bitcoins? I'm worried if i run x4 gpus there will be no return at all. (I've been CPU mining litecoin as a test and the solo mining so far has shown 0 ROI). -D The amount of BTC earned by GPU per day will drop. BTC exchange rate will probably rise.. feel free to make your opwn calculations ; ) |

That's 50$ more than MSRP.. Probably 7790 is too 'hot' now) |

Ok, well, now there's no errors when I open GPUZ, the OpenCL box is ticket AND cg miner doesn't instantly close when I open it. However, when I put all my pool details etc in cg miner, it closes itself but with no errors...  Create startup script f.e. "start.cmd" write there two lines cgminer.exe --blah --blah ur params pause launch that start.cmd now you will see what cgminer says |

Is 7790 available in Sweden?
Can you point me to the store plz?

Cheers for that. I already have SDK, so I'll get the new beta drivers for Catalyst (seeing as I already have the latest) and try again. I'll report back. There are also issues when using certain Catalyst version with certain APP SDK versions.. As it is easier to reinstall SDK - no reboot required, I suggest you start with SDK ; ) You can try different version of SDK or just find version of Catalyst which includes OpenCL already and was tested to work by ATI |

What does GPU-Z about your OpenCL support?
Drivers and/or OpenCL issues are very likely.

If s1 interested I have cgminer 2.11.3 x64(with scrypt, opencl and cpu) compiled for Mac OS X 10.6.8

I did pay with paypal, but as a gift. I reported the transaction but paypal denied my claim so I don't think that will work... Most of the money came straight out of paypal balance as well. What was the reason for denying your claim? Push paypal harder.. Interestingly enough, some ppl say PayPal reverses even gifts, and some ppl(you f.e.) on the other hand report that PayPal won't reverse gifts.. |

51% attack is non-profitable for attacker => probability is low
It is profitable, dead coins still exist and if that address ever becomes active again they will no longer be considered dead. But the amount of dead coins there are contributes to a function that will lower the difficulty by a small percentage(once a threshold is reached). Edit: -Or do you mean the decrease in value of the currency would make the attack pointless? Yes. Basically if you will create a device which will be hashing at >=51% of of overall BTC hashrate it is much more profitable to just mine new blocks or receive transaction fees. Assuming that you actually pay for your hardware. Ofc if attacker is just very very rich and wants just to destroy BTC.. then attack is not pointless ; ) |

I realised after I posted it that I shouldn't have said "fixed price". I was thinking in my head of being told once that $1 was equal to a fixed amount of gold that it could be traded for.
Thanks for the explanation!
It used to be. And so it was written on the banknote. However, now USD and all(?) fiat currencies are worth the amount of trust ppl have in them, the same as with BTC. |

Anyway.. all GPUs are/will be absolete very soon.
I think this may be what I am referring to, can you explain? Check "Avalon ASIC" performance ; ) Ofc it's not mainstream yet, but more and more ASICs will start mining. And if BFL finally releases theirs.. Anyway, it is pretty much impossible to compete with ASICs using GPUs. |
