Title: Using Onboard GPU for normal Work while mining with and AMD GPU?
Post by: KJaneway on April 08, 2013, 03:26:59 PM
Hello,

I am wondering if it is possible to use the IGP of a Sandybridge Processor for the monitor picture, while having a 7590 in a PCI-E Slot available for Mining. How would i do that?

First you need dummy plug for your card.
http://www.overclock.net/t/384733/the-30-second-dummy-plug

Install the graphics card, boot up the operating system with your monito plugged into the GFX card, install amd driver.

Jump into UEFI aka bios, set graphics to IGP, not auto.

Shutdown, install the dummy plug.

Boot up the system, install your Intel graphics driver, reboot.

You should be set to mine off your AMD card, while being on the IGP for your monitor.

Yes, this can be done, I am and have been doing it for a while on my I3-2100 and two 5850's.

Could you explain why do you need this dummy plug ? I don't have real experience but thinking normally the cards should be recognized by system when using integrated gpu.

I used a dummyplug. It is needed for windows to simulate that another monitor is plugged in. Otherwise the card would be deactivated.
But it didn't work. I was able to start to Windows, but cgminer doesn't detect the 7950

You got the amd driver installed & sdk installed?

Post by: KJaneway on April 08, 2013, 10:17:52 PM
Yes. I am using AMD APP SDK  2.8 and Cataclyst 13.1 When I use the 7950 as primary device without the IGP, than cgminer works correctly. It only fails when using the IGP and starts mining with that instead.  (Running under Win 7 64bit)

I believe then, you need to find which platform the gpu is, and direct cgminer to that platform.

I am not quite sure for cgminer on bitcoin, but for litecoin's cgminer there is a platform switch you can use.

Maybe check the readme for cgminer bitcoin? Look for something about platform, or open the readme, hold CTRL and F, type in platform. See what results pop up.

Hopefully someone can pop in and fill us on some info.

cgminer -n
will tell you the platforms and devices installed, then select one with
--gpu-platform

Post by: KJaneway on April 09, 2013, 08:38:48 AM
Ah thanks, that helped it alot.
Now my 7950 works. But I cannot change the gpu settings for Overclocking. How can i fix that? When i go to [G] for GPU Settings, then I only can cange the Intensity but [C] Change settings is not shown anymore. cgminer is also unable to read GPU temperature and fanspeed.

Edit: Adding --gpu-engine 1000 doesn't change the Hashrates also (I tested it yesterday and it should do so)

By the way: i encountered a similar problem on my Linux Rig when starting cgminer in a screen session. The Problem was that no X-Session was available to screen. After solving that issue everything worked well. But I have no clue how to solve this in Windows.

My actual commandline:
 --scrypt --gpu-platform 1 -o stratum+tcp://coinotron.com:3334 -u *** -p ***  --thread-concurrency 21712 -I 18 -g 1 -w 256 --gpu-engine 1000

And here my cgminer -n output:

Can't remote into windows and start with monitoring. Must start cgminer locally on the machine for monitoring to work.


Title: Re: Using Onboard GPU for normal Work while mining with and AMD GPU?
Post by: KJaneway on April 09, 2013, 11:41:31 PM
Ah I started it locally. Monitor was connected to IGP. Dummyplug in 7950. PC Restart. Then minerstart from commandline with given attributes:

 --scrypt --gpu-platform 1 -o stratum+tcp://coinotron.com:3334 -u *** -p ***  --thread-concurrency 21712 -I 18 -g 1 -w 256 --gpu-engine 1000

the --gpu-engine 1000 command at the end does nearly nothing. I am also not able to overclock my Card via the Cataclyst Control Center and AMD Overdrive. It seems as if it would not be there. When i start just with the monitor connected to the 7950 (I cannot use dummyplug for IGP) than all works fine.

Any Idea?

Post by: brekyrself on April 09, 2013, 11:57:47 PM
I'm in the same boat.

Using onboard for display of dual monitors and two 5850's to mine.  One of the 5850's allows overclocking while the other will not budge from default settings.  GPUz also shows 0% load on the card that will not overclock yet it is hashing according to cgminer.

I'll mess around with the dummy plug tomorrow to see if I can figure this out.

Usually most motherboards don't support using both Onboard and and PCIE at the same time, it's one or the other. If the board detects a card onboard graphics are disabled automatically. Like say, most boards with onboard video, but not all.

Sandy and ivy bridge isn't onboard, actually. IGP is imbedded in the processor. Making this able to work, and to stop UEFI from auto picking, you set this option to manual in UEFI, pcie or IGP.

Btw, KJaneway, had you got this solved?


Title: Re: Using Onboard GPU for normal Work while mining with and AMD GPU?
Post by: KJaneway on April 10, 2013, 11:39:41 AM
Partially solved:

I managed to use my monitor together with the IGP Port while mining with the AMD GPU. That works fine. Only think which is unsolved so far: In this configuration, I am unable to overclock the GPU or even read their temperature an fan speeds with CG miner.
When i plug in my monitor in the AMD Card, and remove the dummyplug, everything works fine. I can start the miner and overclock the GPU to whatever I want. After switching back the monitor to the IGP, cgminer crashes. I can restart it, but GPU is then again neither by cgminer nor by Cataclyst Driver Software tuneable anymore.

One other thing I can suggest. Try 13.2beta7 amd driver with supplied sdk.

Source.
http://support.amd.com/us/kbarticles/Pages/AMDCatalyst132BetaDriver.aspx

Main download link.
http://www2.ati.com/drivers/beta/AMD_Catalyst_13.2_Beta7.exe

Express Uninstall the old amd driver you have installed, use driversweeper to clean the ati/amd residue left over files.

Install 13.2B7 with supplied SDK, do not install the drag and drop package option check box, I find this package messes up installs for some reason.

On board GPU won't be recognized by the mining software if there are other GPU's in the PCI-E slots. Thats my experience regardless of OS and Mining software. Must be a mobo thing!


Title: Re: Using Onboard GPU for normal Work while mining with and AMD GPU?
Post by: Operatr on April 10, 2013, 12:06:05 PM
It is a motherboard thing, most of them, not all but the vast majority, will support only onboard or only PCIE graphics at one time. Adding a graphics card to the slot will automatically disable the onboard chipset and make the card the default. Even still, most onboard graphics engines are weak anyway.

Kjaneway, here is a photo of me utilizing my IGP for dedicated graphics for my monitor, while mining 2 5850's.

This should work for you regardless, it is a sandy bridge, it should work. Lets keep going at it, we'll get it to work. Btw, my crossfire is hooked up but disabled, so don't pay any attention to it.

Do you have the latest bios installed on your board? Also, I'd recommend trying that 13.2B7 AMD driver.

Mine is an asrock z75 pro3 bios p1.80. Yup, I can overclock them. They are overclocked at 944/1180 for both. 72f degrees or so.

I don't know how much different cgminer bitcoin is from cgminer litecoin. But, for cgminer litecoin, I use a cgminer.conf file for my cards. Let us know if you're using a cgminer.conf file for your configuration or switches in a bat file.

Hey, good tip men, hey can i use the 47Oms? i have some here on my electronics box, always keep this kinda stuff haha
they are new, bough for some stuff but these i never used(doesn't matter if its used but...) i have other too, some on K scale too

so can i use 47Oms resistor?

Edit #1-> i did the dummy plug :D just use 2 47oms in series bettwen 95 and 97 oms(i check it out with multimeter to be sure of that(don't wanna hurt my babes haha)

hey, when i Open GPU-Z says Intel OpenCl Bug detecded, same thing happended before, i did this http://notepad.patheticcockroach.com/3624/fixing-a-catalyst-opencl-mayhem-catalyst-13-1-13-3b2/ (http://notepad.patheticcockroach.com/3624/fixing-a-catalyst-opencl-mayhem-catalyst-13-1-13-3b2/)
and fixed that for my amd gpus...
bot no that doesn't work, i did already unninstall all, like that link says, now is not working...
And if i Open Guiminer/cgminer i get....guess what i get....a nicely BSOD
yah, that's right....some about atikmdag.sys some like that...

i wish i don't have those issues, but i have :(

can u help us to solve this? i'm trying to put both xfx HD7950 to mine, while using my PC for browsing or even gaming (like CS, Point blank, minecraft, maybe even crysis 2 + bucks of tweaks to make it run on hd2500 more smoothly haha)

I have the first generation Clarkdale Core i5 processor. It has graphics on the processor too. Is there any way to use the onboard graphics for display and keep the card dedicated for mining?

I followed the instructions above and have actually hooked up a second monitor with the graphics card; but cgminer -n shows no GPU detected.

Should work with Clarkdale OK - it's your board that's likely the issue.  I run the onboard video with both a 2nd Gen and 3rd Gen CPU (Pentium G620 and i3-3225).

Likely the BIOS on your board doesn't allow running the iGPU along with other GPUs - it's not really something people have wanted to do until recently.

I'm running the i3-3225 on an old P8B WS - using the HD4000 for "work", and the 2x7950 for mining.  No need for dummy plugs either.  Heck, I even mine Litecoins on the HD4000 when I'm not at the computer, every little helps!

You have to first boot from the graphics card and install the AMD drivers.  I've tried with 12.6 and newer, also make sure to install SDK.

Then boot into bios and set the mobo to IGPU and save and exit

Next pull the plug from the back of the video card and plug it into your mobo.

Then put a single dummy plug on the video card that is in the first (main) PCI-E x16 slot.  Yes it works even if you are using 1x risers as that's all I use.  No the other cards don't need dummy plugs. (though, some users have reported to need dummy plugs on all cards.)

Then reboot

Then control all settings from within cgminer as I've found MSI afterburner will lose voltage control etc.

Voltage control (if your card supports it), speed settings, fans, etc all work if used in cgminer, verified through GPU-Z.

This has worked for me on both Asus and MSI Z77 mobos using Ivy Bridge CPUs.

YMMV   8)

As for the dummy plugs I am using 100ohm resisters.  I read online anything between 75-150ohm is fine.  Make sure you get ohms and not kohms.

Here is how you make dummy plugs for any inquiring minds.  And of course you can always finish them off with some hot glue ;)

Yup, this is it, right here. to easy. Whats is weird, I tried one dummy and no dummy plugs, vs using two dummy plugs, and with only one plug, the second card is recognized but not usable, without both dummy plugs, both cards are not recognized. In my what ever situation it is, I need two DP's, one for each of my cards. weird.

These directions should be stickied some how. As more come to try and do this, this thread will be buried and post 35 will be hard to find.

Sorry to go back to the OP, but why do you want to use the IGP in the first place as opposed to one of the cards?

In my experience cgminer can easily manage the primary display by just playing around with the intensity setting of the card to still allow for completely unhindered user experience with windows and media playback (ie. nil delay in rendering 2D and video which I assume is what you meant by "normal work").

Getting a perfect balance of intensity on the display device will probably take you <5 minutes of trail and error, which seems like HOURS less effort than what you've gone through to get the IGP+Cards working to you liking.

In fact, I believe the default settings of cgminer have the intensity set to not interfere with or slow the user interface.

Yes I saw the title, but still my question is: why?

What possible advantage would you have? I suppose you might get a few extra MH/s or KH/s (depending on the algo you're mining with) because you might be able to set the card intensity 1 value higher... but really it's not going to make a huge difference.

He, others and I, would not need to put any more stress on the mining gpu's. So, all your basic work is loaded on the IGP rather putting any more stress on the mining gpu's. Also, you could ramp up the intensity without any desktop lag interference because, well, the IGP takes care of all the desktop work, like browsing ect. You might find a slight lag, but nothing like the lag as if you ran the mining gpu as a miner and desktop usage < that is horrible, You would need to run intensity 13 or something low, which sucks, otherwise with high intensity, you will not be able to do anything on your desktop.

And have you tried this method, of this topic before? If so, I'd say you have a say so in it, if not, then why answer something you "think" "but really it's not going to make a huge difference." It's all of the world difference for users that use their mining rigs as a regular day usage PC. :) Title really answers your why question, but above is a deeper explanation.

Looking back on this thread, OP stopped responding when the thread was 1 day old and seemingly without a solution to the problem. This thread has been necro'd 3-4 times by different users over the last 3 months since then. I was simply offering another point of view to the discussion, that perhaps people were going about a huge amount of effort for little gain (a few dozen khash/s if that). For example, I believe that every persons time has a price attached to it, unless they are too young to work, a non-working student, retired, or otherwise unable to turn an income. I assume that at some stage OP would have spent so much time playing around with this problem that he/she could've just picked up an extra shift at work or two and then purchased the next card up in the series, ran the PC without IGP, with a slightly lower intensity on one card, and still had been better off. Perhaps I just have a strange way of looking at things...

It's great that this thread keeps getting bumped. It allows other users to even more put more use to their pc if it is a daily use pc. I could see if you're mining farmer, then this thread has no point. Huge amount of effort? Really? Lol...  Takes no effort at all. And no time at all as well, less than 5 minutes. :)

Putting this here so, blazin ain't being cock blocked...

You have to first boot from the graphics card and install the AMD drivers.  I've tried with 12.6 and newer, also make sure to install SDK.

Then boot into bios and set the mobo to IGPU and save and exit

Next pull the plug from the back of the video card and plug it into your mobo.

Then put a single dummy plug on the video card that is in the first (main) PCI-E x16 slot.  Yes it works even if you are using 1x risers as that's all I use.  No the other cards don't need dummy plugs. (though, some users have reported to need dummy plugs on all cards.)

Then reboot

Then control all settings from within cgminer as I've found MSI afterburner will lose voltage control etc.

Voltage control (if your card supports it), speed settings, fans, etc all work if used in cgminer, verified through GPU-Z.

This has worked for me on both Asus and MSI Z77 mobos using Ivy Bridge CPUs.

YMMV   8)

As for the dummy plugs I am using 100ohm resisters.  I read online anything between 75-150ohm is fine.  Make sure you get ohms and not kohms.

Here is how you make dummy plugs for any inquiring minds.  And of course you can always finish them off with some hot glue ;)

Haha good man :D

Yeah it's really fast and easy to do, it's just the matter of doing things in the right order.  Nobody should have to explain why people want to do this, anyone that pokes fun at such an obvious piece of common sense is just looking for an argument.

Mileage probably varies wildly from card to card, & different chipsets, drivers, etc.  But I can say with 7970s dropping the intensity down from the required 13 for full speed to 12 loses about 50% hashrate.  And even then you still can't watch HD Video without major lag.  That includes many software programs such as 3D imaging, Adobe Creative Suite, Youtube informational videos, even some Microsoft Apps, and many random things here and there while surfing the net.  Even with an oc'd 3770k in the rig.  Most anyone here can agree why waste useful hashes when you don't have to, and when there is a perfectly good Intel HD graphics right there and ready to go to run the system, then the better question is, why not.

No cards need dummy plugs.  It's bollocks, and has been for nearly 2 years.  People who even think dummy plugs are the dummies.

As I said months ago in this thread that I'm running a pair of 7950 for mining and the HD4000 video out of my i3-3225.  Set the BIOS to assign priority to the Intel video, boot in to Windows, install the Intel drivers, then the ATI drivers, job done. 

Tested with three different motherboards (Asus P8B-WS C206 chipset, MSI B75IA-E33 B75 chipset, Asus P8H77-I H77 chipset) and three different CPU (G620, i3-2100, i3-3225).

LOL Thats funny. My Thread is so old and so undead.

I tried many things to solve that issue, and something worked. But I was unable to figure out the exact trick. Unfortunately although i set GPU priority in BIOS to Onboard, every now and then after restarting the PC the Monitor stayed black and shows neither a picture at the onboard port nor at the Radeon card. Now I only use the ATI Card and everything is fine except of a laggy system while mining.

That's a stupid BIOS limitation in that HP model, where enabling the iGPU with a discrete GPU only works with nVidia NVS300 and NVS310. 

See: http://h20195.www2.hp.com/V2/GetPDF.aspx/4AA4-4148ENW.pdf

Furthermore, HP is limiting mixed graphics configurations to 2D graphics cards from NVIDIA, namely the
NVS300 and the NVS310. Customers who need
four 3D accelerated displays should consider the
HP Z420 Workstation.

First you need dummy plug for your card.
http://www.overclock.net/t/384733/the-30-second-dummy-plug

Install the graphics card, boot up the operating system with your monito plugged into the GFX card, install amd driver.

Jump into UEFI aka bios, set graphics to IGP, not auto.

Shutdown, install the dummy plug.

Boot up the system, install your Intel graphics driver, reboot.

You should be set to mine off your AMD card, while being on the IGP for your monitor.

Yes, this can be done, I am and have been doing it for a while on my I3-2100 and two 5850's.

Reviving an old thread just to say thank you!

I had been trying to work this out with my Intel MoBo and 7950 GFX card. After many failed attempts I was about to give up, but your instructions have precisely worked. I followed them in order and now I'm successfully running my display with integrated graphics and using 7950 for dedicated mining.

Thank you!

People have had different experiences regarding dummy plugs. Some require it, some don't. In my case it was Intel motherboard, which required dummy plugs. You can try without them first; if it doesn't work, then you should use them.

As for TRIXX and all, I am using AMD Catalyst Control center which works fine; also my miners display the stats perfectly.

Your integrated graphics probably has the drivers installed already, so don't worry about them. Just follow the sequence in correct order.

1. Plug the monitor in 5850, start the PC, verify/install latest AMD driver (Catalyst) for 5850.
2. Restart PC, go to BIOS, change video priority from 'Auto' to 'IGP'. Save changes & Exit from BIOS. PC will reboot automatically.
3. While computer is booting, unplug the monitor from 5850 and place dummy plug there.
4. Plug the monitor into integrated graphics.

You should be done.
Are you doing it in this proper order?

OK I'm running into this same frustration. Here's the setup:

   
MSI Z77A-GD65 LGA 1155 motherboard
Intel Core i3-2100 Sandy Bridge processor with HD 2000 graphics
Powercolor Radeon 7950
Windows 8.1
sgminer 4.0.1
Latest non-beta drivers of AMD Catalyst (13.1 I believe)

I don't have a dummy plug so that's not an option unless I buy/make one.

I installed Win 8 and did all the updates without the Radeon card (last part to arrive).

I connected the Radeon card and installed the drivers, tested mining and everything was working fine.

Moved the machine to the closet where it will be run and hooked up the monitor (an old 1024 x 768 LCD monitor with just a VGA plug) to the main board, and setup the EUFI to use the IGC.

Downloaded and installed the latest Intel drivers for good measure.

Now when I run my batch file which does this:

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
sgminer.exe -c sgminer.conf

I get this message initially:

[23:02:52] ADL found less devices than opencl!

[23:02:52] WARNING: Number of OpenCL and ADL devices did not match!
[23:02:52] Hardware monitoring may NOT match up with devices!

And after a few moments it continues, but the hashrate is pretty bad and there's no information displayed for the card's temperature or fan speed. I'd really like to get this to work properly!

Here's my sgminer.conf file with the pool information removed:

@QuadraQ: I was also receiving the same error, then I had to use the dummy plug. Try it out. I made them myself, its very evry easy.  You just need the VGA-DVI adapter and three 68 ohm resistors, which are easily available from radioshack or eBay and they're dirt cheap.

Make sure to follow the instructions in proper order, step-by-step.

Say I have linux mint, a sandy bridge CPU, and two AMD cards. (I do).

How do I use the intel graphics for my desktop, and use the cards for mining with CGminer ?

This would be very nice.

I already tried, but failed. i don't really know what I am doing with the various config files and such. Maybe a cool dude has a solution ?

That is tricky thing 8)

During setup you can break you X few time, so prepare backups, liveCD and some kind of fallback with internet just in case (like laptop, smartphone, anything that could help you to find answers).

Tested on fresh install of Ubuntu 12.04, i5-3570K(HD4000), AsRock Z77extreme3 and ASUS HD7870 DC2, but it also should work as well on any other combination of Intel HD and AMD graphics. HD7870 connected via DVI and HD4000 via HDMI, integrated graphics selected as primary in BIOS.

It’s not step by step manual, as I were using a system for a while during all configure-use-reconfigure cycle, so I can’t recall all my actions and dependency resolving :) But I can share all my current configs and installed software versions.

1. First of all you need to make sure that you have fglrx installed, I’ve got it installed automatically during Ubuntu installation, the version is 2:13.300-0ubuntu0.0.1. According to apt-cache policy it’s fglrx-experimental-13, also I have fglrx-amdcccle-experimental-13 and fglrx-pxpress installed. As for a xorg, I have xserver-xorg 1:7.6+12ubuntu2, xserver-xorg-video-intel-dbg 2:2.17.0-1ubuntu4.4 and xserver-xorg-video-intel 2:2.17.0-1ubuntu4.4.

So if you don’t have fglrx, install it with
Code:
sudo apt-get install fglrx-experimental-13 fglrx-amdcccle-experimental-13 fglrx-pxpress

And if you don’t have intel driver
Code:
sudo apt-get install  xserver-xorg-video-intel-dbg

2. Next you need to create 2 xorg configs in /etc/X11/: one for intel, another for amd. Here is my files:
xorg_intel.conf

As xorg and fglrx have a lot of common libraries (like libglx.so), you need to specify ModulePath to fglrx versions to use 2 drivers simultaneously.

3. To activate intel as a primary driver use switchlibglx from fglrx:
Code:
/usr/lib/fglrx/switchlibglx intel

4. Create user for mining, in my case it’s called  miner. You can do it via GUI, and grant it administrator privileges or via terminal
Code:
adduser miner sudo

5. Configure lightdm: /etc/lightdm/lightdm.conf
Code:
[SeatDefaults]
greeter-session=unity-greeter
allow-guest=false

[Seat:0]
xserver-layout=seat0
xserver-command=/usr/bin/X -novtswitch -keeptty
xserver-config=xorg_intel.conf
user-session=gnome

[Seat:1]
xserver-command=/usr/bin/X -sharevts -novtswitch -isolateDevice PCI:1:0:0 -keeptty
xserver-layout=seat1
xserver-config=xorg_amd.conf
user-session=ubuntu-2d
autologin-user=miner
autologin-user-timeout=0
6. Reboot and prey :D Now you should be able to use intel HD for your main user, and in terminal just calling
Code:
su miner
export DISPLAY=:1
fglrxinfo
get access to your AMD card
Code:
display: :1  screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: AMD Radeon HD 7800 Series
OpenGL version string: 1.4 (2.1 (4.3.12682 Compatibility Profile Context 13.30))
Have fun :D

If anyone comes across this thread that uses UEFI, and has any problems booting up their win7-8 OS on the dedicated graphic cards after disabling the onboard graphics to game after mining or the other way around.

Do a cmos reset from the motherboard. Make sure dedicated gfx card is set to bootup and not onboard or the other way around if that's the way you want it.

I ran into this problem, and for the life of me could not figure out what was going on. UEFI, I believe was getting something mixed up on board ports, causing failed boot from the dedicated gfx card.

cmos saved me a few time already.

What I was doing was using onboard gfx as web browsing etc, and using the gfx card for mining. Well, I rebooted into UEFI, set gfx card as main display device, hit F10, removed the dummy plug, plugged my monitor into the gfx card then I hit Enter =  saving UEFI blindly. On boot up of windows 7, I'd get a greyed out screen after the windows7 emblem as to where you would normally be at the login screen.

I kept getting driver problems. etc as well.

Long story short, I had a intel raid utility problem, where when in UEFI was set to raid, my raid utility would not show, after days of work, I finally reset cmos on the board, that fixed it.

Because of this, I was able to fix the above problem with the dedicated graphics card.

If you ever have a board, card, uefi, any of those type of problems, don't forget clear cmos is your best friend.

Edit:
It's in archival.
