I have a 7970 dualx sapphire and it does fine, will hit 700-720 when pushed hard.
afterburner shows it as a "7900 series"
my cgminer settings:
--thread-concurrency 21712 --intensity 20 -g 1 -w 256

OP, I assume you have proof of access/ownership of these cards and the right to rent them out?
Any kind of uptime management provided with this service, or do we manually have to monitor the machine via some kind of remote access (teamviewer, logmein etc)

try this...
--scrypt --thread-concurrency 21712 --intensity 20 -g 1 -w 256
at 1000/1500 on my sapphire 7970 I get about 680khash.
If i go up to 1050/1600 i'll get 710khash.

Out of curiosity, why not mine with them yourself?
some people might want to "add capacity" without dealing with building a machine, powering it, cooling the environment it is in.. reselling the hardware.. etc honestly, if profitablity stays where it is now.. $140 return on $250 in ONE MONTH is DAMNED amazing. |

protip: sometimes AMD drivers or the card get REALLY wonky and slow down like 10% from where it should be.
It has happened to me before and is happening again. I have 2 rigs with the exact same cards but 1 is getting 570 each while the other is getting 630 each (same settings and OC)..
to remedy: I imaged my windows install.. did a fresh install.. reinstalled drivers.. restored my old install.. and bam.. it was back to normal.

the new gigabyte 7950's can get 650 khash at full bore. That model is voltage locked though.. so it isnt nearly as good for the miner wanting to get say 570 khash with a lot less power usage.

Yes, I regret not dumping 200 BTC into a Single 10 months ago. That 200 BTC is now worth $28,000. I am so sad! honestly, if you REALLY felt BTC would have increased in value it would of been bset to buy 200 BTC with cash ASAP after placing the order, then you wouldnt of been out the mone)  |

I've been thinking wether or not a cpu manufacturer could come up with the idea of assigning some die space to putting a bitcoin mining unit on one of their products.
What would be the cost for them and could it be a good-enough feature to increase sales by enough to make it viable?
why on earth would they waste space on 100% of cpu's when only 0.001% of users would utilize that space? Also.. prepare for HARDCORE botnet abuse if CPU mining was reasonably profitable again. |

LTC has been more profitable for the last 14 months except for about 2 weeks cumulatively where it dipped into the 90 percents.
It is hard to comprehend how profitable LTC mining would have been for one that ONLY mined it say the last 6 months with even just 3 mh/s and never sold their stash. |

whats more profitable atm?
I'm mostly ignorant about LTC. However, BTC is at $164 now. I find it hard to believe LTC is more profitable than BTC, especially when you have to have that memory ramped up to be effective. M the exact same hashing power will get you 1.88 BTC if you mine LTC and sell it in the same amount of time you will mine 1 BTC if you just mine it directly. |

What about for LTC  LTC and NVC are currently THE coins to care about for GPU mining (and will continue to be that way for the time being). honestly.. the card that can do it most power efficiently will end up being a BIG winner, espescially with summer coming up and having to really fight a big battle with heat to mine profitably once you have to use electricity to mine AND cool the house. |

All hypothetical of course.
Due to the high price of bitcoin, will that affect the silk road? Will people turn to different markets that deal with "proper" money [ducks and runs for cover] and hoard their BitCoin causing deflation?
Are there any figures?
why do you think it would change? its just something that used to cost 20BTC when it was $10 each will now cost 1BTC.... |

Total 9,075,301 kH/s  that is downright impressive, considering it is almost all cpu/gpu (unless someone developed a FPGA and is keeping it a secret for themselves) |

The one thing you want to be careful of is the power you are using with your cards. If you are undervolting or using a card that draws little power you will be right as rain. If you have a factory overclocked and over volted card, you will want to be VERY VERY careful. You may end up needing powered risers at that point!  wait.. so what happens if one uses overclocked cards on a standard non-powered riser? I just built a new machine with 2x gigabyte 7950s (the new edition, has a 8pin and 6pin pci-e power with a 1.25v locked in) |

thats why most guys buy 7950 for LTC mining ...
true, my 7950 with reasonable OC can mine at 550, and some ppl use their MSI WC mine at 600 but the price of a MSI WC is almost the same as the 7970 I got......  being the owner of 5 7950's (all gigabyte) and having got my first 7970 yesterday (sapphire dual x)... 7950's are ABSOLUTELY the winner for value. 650 on a 7950 vs 710 on a 7970... its a no-brainer.. the 7970 i'll use as a gaming card this summer when i shut down my mining due to heat |

Vardiff is now on both servers.
THANK YOU. My CPU miners can now find shares more than every few minutes. |

How can they have a 16k difficulty mining at 10% of the bitcoin network when the bitcoin difficulty is orders of magnitude bigger?
Also, didn't they started from difficulty 1? I thought so and that they shared the code with bitcoin . if so, how can they have already had a difficult retarget that brought them to 4000?
I don't know, I don't care.
Whats happened is the difficulty was 1 and because of all the hashing power being pointed towards the Bytecoin network the difficulty is readjusting at the fastest possible amount that it will allow. So far the difficulty is jumping 4 times on each retarget, and because it can't jump more than 4 times (I think this is true of Bitcoin too, that the difficulty can not retarget more than 4 times the current target) then the blocks end up getting solved far quicker because the retargets are happening as fast a what allowed by the code. so after 16,000 it will jump straight up to 64,000 and so on before it equalizes and blocks start getting solved in the 10 minutes time span again. any new altcoin that starts at diff1 is BS. it needs to be at least 1600 IMO, as diff 1 just lends the insiders and very first folk to suck up WAY to many coins right off teh bat. |

I just thought of a great idea.... add an option that allows a user to essentially enter in the exact same information as you would to get guiminer up and running...but instead of mining in the gui it will spit out a config file that you can copy to the desktop and run. IMO, a properly configured cgminer is almost more user friendly then the guiminer (however guiminer is easier to setup for a complete new guy). I can't imagine it would be THAT much work to implement, however I an not technically capable of such a task.. so I suggest it here instead keep up the great work taco. |

is there a way to actually be safe in the exchange market?
just like everything else when it comes to keeping bit currency online... NEVER keep more on them than you are absolutely OK with losing. Sure there is a chance the site might get hacked or run off with your coins, but if you made say.. $500 trading on there and only ended up losing $200 of coins... you still came ahead by using their services. just dont keep your whole btc stash on some online site.. |
