i have a i7-2700K and it has a integrated graphics can i use the integrated graphics to mine bitcoins?

You don't.

Even if you could (which you can't) Intel integrated graphics has such low IntOp performance that we are talking about a couple bitcents a day (and spending more than that in power).

power is free.

is there a tutorial on how to do it? and how many MH can i get.

That list doesn't have any Intel GPUs on there.

If you really want to try it out, first you need the Intel OpenCL SDK (http://software.intel.com/en-us/vcsource/tools/opencl-sdk). Then your miners can pick up any OpenCL platforms, and start mining. I would not expect hardly ANY performance out of that at all. If you get more than 20MH/s, I would be shocked.

Which is about .2 BTC per month, worth about $2.   Extrapolating that rate for a year that is about $24 per year.  Except that the block reward adjustment drops in half in about eighty days.   And higher difficulty will drop the production for your hardware as well.

If you just want a hobby, knock yourself out.

That's if you can squeeze 20Mh/s out of it. I'd put it at closer to $5-10 over the next year. Not worth the extra heat/lifespan you're taking off your CPU.

i am downloading the intel opencl SDK will report after download

10 min left

8 min left

Just let us know when it's all done and you're mining.

well the download is complete now and i am installing it.

i tried to mine to cgminer and cgminer did not recognize the Integrated Graphics is there anything i can do to get cgminer to recognize the integrated graphics

run "cgminer.exe -n" and see if it can see the OpenCL platform.

it show's 1 gpu devices max detected.

the 1 is my ATI Card.

MSI RADEON R6670 MD1GD3

are you ADHD or something? also, learn to edit your posts, this isn't twitter.

any reply's to how to get cgminer to find my Intel integrated graphics?

Does it support OpenCL?

yes and i installed the intel openCL SDK

Chipset?

What do you mean by Chipset???

Even if you went to the effort of making it work, it just isn't worth it. For a while I used a 5450 which got me 15mhash a day, it just isn't worth the strain on your system. If you have a 6670 in your computer, why don't you use that?

i am using the 6670 but i am only getting 109Mhash so i want to mine with Integrated Graphics and see the speed.

Your integrated video would be very lucky to get 10% of that speed....

but how do i make CGMINER to recognize the Integrated Video??

One more time this time bolded for emphasis.


It is NOT possible to mine on Intel Integrated Graphics.  Not sure how much clearer that can be made.

but someone on this thread said it was possible

I may have been mistaken. I did know there was an OpenCL platform available, but perhaps there are no miners that can utilize it?

Intel OpenCL platform is "non-standard".    The openCL acceleration for CPU is fairly good (CPU will execute OpenCL kernels) but that is kinda useless for mining.  Intel OpenCL drivers for GPU are a "mess".  To my knowledge nobody has gotten them working and it likely would require writing a custom kernel.  That kinda defeats the point of OpenCL (writing generic code to execute against OpenCL compatible hardware) but I guess it could be done (maybe).  Given the worthless performance of Intel GPU, there would be no point.  I don't see anyone releasing Intel compatible OpenCL kernel anytime soon.

is there a custom OpenCL SDK for Intel Integrated Graphics

No.  The SDK is produced by the hardware manufacturer.  Nobody has the technical expertise to make a "custom" one.  If you have Intel hardware you use Intel OpenCL SDK.  If you have AMD hardware you use AMD OpenCL SK.  If you have NVidia hardware you use NVidia OpenCL SDK.

Intel implementation of OpenCL is flawed or incomplete when it comes to GPU (works perfectly fine on the x64 CPU portion).  Standard OpenCL kernels for mining simply do not work.  Period.  In theory it may be possible to make some non-conmpliant OpenCL garbage kernel which gets around Intel's flaws and works on their GPUs.  Nobody is going to do that because the hardware is so weak.  Why would someone with the skills to build that (if it is even possible) spend the hundreds of hours just to produce a kernel which only works on Intel GPU and is the slowest of all hardware available to users?  The mining kernels in use now are the product of hundreds of hours of development.  Nobody is going to do that for some joke of a GPU made by Intel.   Even IF you did get it working a $10 AMD gpu you bought used a fleamarket would be magnitudes faster.

TL/DR:
As I said in the first post.   No.

What about this thread: https://bitcointalk.org/index.php?topic=86307.0 ?

Is there a tutorial anywhere on how to mine with Integrated Graphics?

Did you even read that thread crazyates posted?


at 4.3MH/s you could make about $0.02 a day. If you walked up and down your local Walmart parking lot you would make more money picking up change... Its just not worth it.

On top of that when the reward drops by half you will be making $0.01 a day.... Plus the difficulty on the rise, I would guess in the matter of a month you would be down to less that 1 penny a day even with free electricity.

Even if you got 20MH/s it would only get you $0.04 a day.

So I should stop running that CPU miner on all the computers at my work? I mean 7MH/s times 6 computers is like $.06 a day!
I'm kidding, I don't really do this.
