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-plugInstall 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?

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

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: c:\cgminer-2.11.4-windows>cgminer -n [2013-04-09 11:09:50] CL Platform 0 vendor: Intel(R) Corporation

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

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?

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?

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.

K, what board do you have?
