Litecoin is currently trading at 98% profitability hash for hash. Discounting the finnicky nature of litecoin mining, the higher power consumption and heat issues, you're still making less currently mining litecoin.
Strange that my machine runs cooler mining Litecoins than Bitcoins? |

2.11.4 works OK for me with a 7950, 6970 and 5870 all in one machine ( FX8320@4.5GHz, 990FX SABERTOOTH). |

So you've been stealing electricity from work and now you can't anymore. My heart weeps for you.
Heh, if it's too cold in my office, I turn on a 2KW fan heater I have under my desk. Is that "stealing electricity" too? Or boiling the kettle to make a cup of coffee? |

any windows.
Not technically correct - I've never used null plugs, and mine on 4 different machines running Windows 7 and 8. |

Crossfire is moot for mining. Period. OpenCL will continue to see each GPU as individual devices that you can mine on one at a time. Crossfire -only- has advantages for gaming. That's it.
Once again! Speaking in theory of gaming performance! Read the comments of the thread before posting! This is a mining forum. There's millions of gaming forums. If you ask these questions on a mining forum, what do you expect?  Besides, Crossfire is broken on ATI cards - Google "micro stuttering". Crossfire at the moment is a big waste of time and effort. |

I run a 5870, a 6970 and a 7950 in one machine. I was also running a 7770 as well, but it died. They worked OK together.

Just run a mining proxy on a RaspPi.

Here's my 1GHash/sec rig  1x5770 and 2x6950 (shader unlocked) You might get 1.2GH/s out of it, if you cleaned out all the dust bunnies.  |

From the images I've seen of Avalon Asics I've never seen them with multiple Ethernet ports and also it has a SonicWall part which is a network security company that is owned by Dell. The auctioner also only provides 1 photo of this "miner" and doesn't show the full device. I see a sticker at the top that says "Rack A", I'm getting the feeling that this is just some ordinary server that has a similiar looking part that identifies with the Avalon Asic (the 3 fan grills). Combined with the fact that the seller wants you to contact them before placing a bid does scream out scam.
Really? Seriously? You can't grasp the concept that it might be sitting on a shelf in a rack, and might have something (like a Sonicwall firewall) sitting on top of it? Looks pretty obvious to me. |

Yeah, you need to use the HD7xxx card in the primary slot (on my SABERTOOTH 990FX that's the bottom x16 slot for some reason). I run a HD7950 in the bottom slot, HD6970 in the next up, then the HD5870 in the top slot. Works 100% for me.

He said that some of the power supplies they use up there will take 110 or 220 also but that once you hook it up it always wants whatever it was hooked up to first. So he thinks they'd put a sensor and a circuit to remember that and burn it to memory forever, rather than just a sensor. Think twice about allowing him to rewire your home. This. Or ask him to lay off the weed for a few days before coming round. |

Mine Litecoins instead, they're still profitable for GPU mining (and if electric is free, CPU mining too).

Sorry, the pictures aren't working on my computer. I can't see the printed board, or the chips, or any of the proof-that-anything-exists screenshots.

Alright i got the motherboard back, they didn't want to flash the BIOS because "that would void the warranty and we cannot take responsibility".
That's horse shit. Flashing the BIOS does not in any way void the warranty. Send them the motherboard back, demand a refund (not fit for purpose), and buy another one from someone that has a clue. |

There's options to disable GPU mining, which made me think it would have cpu only capabilities.
No, that's for disabling GPU mining on a machine that's controlling ASICs or similar. |

I'm unable to get cgminer working on a debian cpu only system. When I use the readme file's recommended configure line:
And it just stops. If I make install anyway, it doesn't want to work. Thanks in advance for any help!
try CFLAGS="-O2" ./configure --enable-cpumining works for BTC. Tried it on testnet (win64). You can use it for testing, but to make real coins you would have to be really lucky or live for a very long time. Which bit of "cgminer doesn't support CPU mining" don't you understand? CPU mining was removed ages ago. 2.11.4 doesn't even have it, and that's the oldest version I have here. |

Nice Yes but in this case Google search doesn't return what you are looking... pool difficulty setting would... Heh, google.com gives different results to google.co.uk - go figure. First hit on .co.uk was the answer using that same search. |

With a big-ass fan like that, the added benefit greatly outweighs the tiny bit of cooling lost by blowing air up the card's exhaust.
