@bathrobehero:
Have you ever tried undervolting the 970? On my 980's I run with lowered voltage, and that allows me the same (high) clocks with reduced power usage and lower temperatures. My power meter broke, so I haven't measured yet the different efficiency levels, but generally speaking, I think that you'll gain the most by tweaking voltage.

Each block is stacked on top of the previous one. Adding another block to the top makes all lower blocks more difficult to remove: there is more "weight" above each block. A transaction in a block 6 blocks deep (6 confirmations) will be very difficult to remove.

I haven't as I'm afraid that each card would be wildly different in terms of how much voltage they require not to crash (long term) on stock speeds because they also have somewhat wide ranges of stable overclocks. If anything I was considering a slight increase in voltage for the 970s as in my case going for maximum hashrate regardless of efficiency is more profitable and the cooling on them is also pretty good. But I might play around with lowering it in the future just to see. |

Cool. Even if you could just run through one card, it would be interesting information to have, adding to your efficiency tables  |

Can you try release 70 please. Lyra2v2 should be faster |

ASROCK H81 PRO MB and DUAL VIDEO--
A number of thread-followers have mentioned that they run rigs on ASROCK H81 PRO motherboards. These boards support Intel CPU-Integrated graphics as well as a wide variety of graphic cards. Is it possible to drive a monitor with integrated Intel video, and mine with nVidia graphics cards (750ti SC)?
I will research the web before booting my new H81 rig, but I'd like to know if it has been done by any one of the readers.
Thank you in advance! --scryptr

-Stop mining on disconnect's to save power.(pallas / flipclip)
Just tried this new feature. Works like a charm! Stops using gpu and continues to work after connection is available again )) Will send some beers to pallas / flipclip later )) \ Send my beers to Pallas. The only thing I did was re-merge Pallas' "network_fail_flag" to master. It was taken out originally because Pallas wanted to make sure it wasn't the reason for the solo-mining failure. It wasn't |

Yes, you can use the processor's onboard graphics card (set in bios to onboard) and you should use it because that means that all of your dedicated cards will have 100% of their memory free which is beneficial in memory hard algos. Otherwise the OS will use a chunk of your primary card's memory. |

You definitely should use internal graphics for display when mining on 750. Cause running on max intensities will do lags on Windows interface. AMD cards will not.

i have never done it on mine - but it can be done ... the radeon integrated chipset that is used is a separate gpu altogether if using the nvidia drivers from what ive been told ... otherwise - the selection of the cards through commandline ( as a conditional parameter on ccminer ) would probably be what you would use to activate which cards are mining ... like i said though - i have never done it that way - as i use headless systems anyway ... and im way too busy ( and lazy ) to go into this ... #crysx |

So how do you mine with integrated gpu is on via miners that can't support to choose opencl-platform ?

thats the point ... you DONT ... the whole purpose of the previous question was simply to use the integrated video - and have the 750ti cards to do nothing else but mine ... id like to research that also - considering that ALL the rebuilt miners ( when they are finished ) will be these same boards ... #crysx |

There still may be problems with ccminer and phoenixcoin-qt wallet. I've never seen this many no's before while solo mining it.  I used a low -i 10 for this test.  |
