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 ...

yup - hence the usb 3.0 powered risers on ALL the farms cards ...

i have burnt out so many in this fashion when i was starting in mining - its ridiculous ...

none of these ribbon risers are ever used in thefarm now ... none ...

apart from that - there is more versatility with the lengths that you get with usb 3.0 risers ... and easier airflow around the usb cables that these ribbon ones ... they act as funneling for the airflow across the machine - where as the round cables that come with the usb 3.0 risers have a very airflow efficient non intrusive round cable ...

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 ...

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.

the min target is probably a bit low compared to the real difficulty

So is that something I can fix on my end?

I achieve this on Linux with the following xorg.conf

Code:

Section "Device"
    Identifier "intel0"
    Driver "intel"
    BusID "PCI:0@0:2:0"
    Option "AccelMethod" "SNA"
EndSection

Section "Screen"
    Identifier "Screen0"
    Device "intel0"
EndSection

Section "Device"
    Identifier "nvidia0"
    Driver "nvidia"
    BusID "PCI:1@0:0:0"
    Option "ConstrainCursor" "off"
    Option "CoolBits" "28"
EndSection

Section "Screen"
    Identifier "Screen1"
    Device "nvidia0"
    Option "AllowEmptyInitialConfiguration" "on"
    Option "IgnoreDisplayDevices" "CRT"
EndSection

Section "Device"
    Identifier "nvidia1"
    Driver "nvidia"
    BusID "PCI:2@0:0:0"
    Option "ConstrainCursor" "off"
    Option "CoolBits" "28"
EndSection

Section "Screen"
    Identifier "Screen2"
    Device "nvidia1"
    Option "AllowEmptyInitialConfiguration" "on"
    Option "IgnoreDisplayDevices" "CRT"
EndSection

Section "ServerLayout"
    Identifier "layout"
    Screen 0 "Screen0"
    Screen 1 "Screen1"
    Screen 2 "Screen2"
#    Inactive "nvidia0"
#    Inactive "nvidia1"
EndSection

In the "ServerLayout" section, I have the nvidia cards assigned to screens to allow NVML to work.  It costs 18MB of VRAM to X, but I noticed no performance decrease.  It is simple enough to disable this by commenting screens 1 and 2 and uncommenting the "Inactive" lines for them.  You will lose temperature, fan speed, etc though.

EDIT:  On Ubuntu, you'll also need to disable "gpu-manager" or the dumb ass thing will overwrite your xorg.conf everytime you log in.  I just commented the entirety of /etc/init/gpu-manager.conf.  Allegedly, this also can be done by passing a kernel param in newer (than 14.04) versions.  Though I don't recall the name of said param.

750Ti allow to place them more compact 

[sp_]

Worked some more on the pentablake miner:

Same clocks as before.

In pentablake sp-mod 1 the rig was doing 215MHASH.
In sp-mod 2 it has increased + 20.5MHASH to 235.5MHASH

The GTX 970 is up 6MHASH
the 750ti is up 3MHASH

Around 10% increase


Sendt for free to the Pentablake Donators.

NICE RIGS! --

Are you running a Windows OS, or Linux?  I am wondering how to add the nVidia drivers without disabling the Intel internal video.       --scryptr
