Topic: Mining on Intel HD Graphics 530, integrated GPU. - page 2. (Read 21353 times)

I tried to mine using my integrated video card (i5-6600k) but I literally got nothing, I used ethminer-0.9.41-genoil-1.1.6 with opencl, the output from the integrated video card was 0 even if the cpu was some degree hotter when it was turned on. Gpuz showed 0% in gpu load, did anyone have been able to get something from those useless IGP?

Probably a bump due to age, but I'm interested in this topic as I want to learn some more about mining, and only presently have an Intel NUC (Skylake) - I want to get the most out of it before putting in capital.

From reading around on Intel's website, a forum post came up:
https://software.intel.com/en-us/forums/opencl/topic/531630

where the poster may have inadvertently addressed the issue of the GPU running at a slow clock speed - their solution seemed to be to keep the GPU busy at all times to prevent it slowing down (with dummy loads if necessary). I wonder if your case where it actually worked well somehow had another GPU load at the time that kept the frequency high?

And there was an interesting blog post from Intel also about using the GPU for OpenCL processing taks instead of sending them to the CPU:

It seems that there are performance optimisations which should be implemented at programming stage in order to use OpenCL optimally. I'm not sure if the programming community really wants to focus on those optimisations, even though it does seem that there is some potential performance gains to be achieved in otherwise unused capacity.
Thinking in terms of ETH, where there are applications outside of of just mining, maybe tapping into OpenCL better would be of benefit?

I get that. I've been mining for a while. My SHA256 hash power is around 12TH/s total and my Scrypt around 30 MH/s. All ASICs. I know the GPU/CPU in my laptop is not designed to run 24/7, and I would never do that. But it still raises the question of why when mining, it runs at it's lowest clock speed. I like to mess around. This project is mostly for the goal of benchmarking different algorithms, playing around with settings and understanding GPU mining a bit better before I invest in a full time rig. I don't intend to generate any real profit or convert my main laptop to a mining rig. I've fully updated all the drivers, so it's not that.

The integrated GPU you are talking about hasn't been built to be used 24/7 at >90% like you would do with mining. You will end up destroying it in a few weeks with an earning from tiny to nothing.

If you wanna try mining you should think about getting a desktop pc and put real graphic cards in it. Right now gtx 1070 or rx 470 are the right choice

it maybe you need the opencl driver from intel.com??  


as in an upgrading drivers from intel website

Yes get a real GPU

Just signed up, first post here. So here's my question, I'll start with the background. So I've been messing around for a while with trying to mine on an Intel integrated GPU. I've read a lot of varying information on the subject, but much of it's outdated and a lot of it is contradictory. So here's what I've personally observed. I've tried various algos and I always and up hashing at rates far below what I should be. Except for one time... Using Intel Extreme Tuning Utility, CpuZ and GpuZ, I was able to deduce the root cause. That while mining using opencl on the Intel gpu, my gpu was running at it's minimum speed of 349Mhz. It can also go to a 'C1E' like state when the screen is still, at which it shows a frequency of 0Mhz. Mining on the CPU alone, the graphics core was in it's 0Mhz state, so I know the jobs are in fact being "routed" through the graphics core. Now I've seen the GPU frequencies (labeled in the Intel Extreme Tuning Utility's analytics as "processor graphics frequency") go above my max core frequency ( which is Intel "Turbo Boost" up to 3.6Ghz,) and technically, it should be able to run at twice the core speed, at least for short time spans, and consistently at, at least 2500Mhz (I've witnessed during stress tests.) But here's my issue: when playing a graphics heavy game, for instance, the GPU clocks right up and performs as it should, adjusting to the change in workload. For all mining apps I've tried, this is not the case. Instead the gpu ramps up to it's minimal operating frequency of 349Mhz, and refuses to go any higher. I've tried to find a way to directly access the bus (as Intel Extreme Tuning Utility only allows for adjustment of the ratios and voltages that affect maximum processing speed, but the governor remains Windows Ondemand,) but it seems nothing exists. That one time I spoke of earlier, I don't know what exactly happened, I started BFGMiner as usual, with the same config file I always used, no new options, and the graphics frequency shot up. And I was getting respectable scrypt hashrates, at the pool! Nothing crazy, but 1-2MH/s (compared to the 10-15KH/s I averaged normally.) It was not a fluke, it was continuous, for a while. Eventually I stopped it so as not to completely burn out my laptop, and have never since been able to replicate the situation. But, I know it's possible. There's just something preventing the graphics processor from scaling to an appropriate level. I've been messing around with ZCash lately, and know I can do a lot better than 15Sols/s. I know it's the same issue. Does anyone have any ideas on mow I might possibly get the graphics card up, an opencl parameter perhaps? any input or help would be great. Thanks.
