Half-correct. He started off by saying that the iGPU sometimes interferes with overclocking AMD cards, but he also said later on that sometimes a dummy plug needs to be used to fool the card into thinking a monitor is attached, and that turned out to be the solution for me.

How many GPU do you have? Because if you hav to buy a Dummy plug for all GPU gona cost a lot...

Right now I have (3) RX 560 with (1) more on the way. Given the boosts in hashrate of ~8% for Ethash to ~11% for Cryptonight per card with the dummy plug attached each plug will pay for itself in 30-50 days. Seems like a good tradeoff to me.

Very interesting feedback. I will try one just for test.

Merit me or don't.

Find some timings online. That’s what I did.

Something else to consider that I just learned about myself is that AMD cards need to have a display attached to operate at maximum hashrate. It doesn't have to be a real display, though - you can get "dummy plugs" that simulate a display for $8US on Amazon: https://smile.amazon.com/Headless-Display-Emulator-Headless-1920x1080-generation/dp/B06XT1Z9TF/ref=sr_1_3?ie=UTF8&qid=1518969028&sr=8-3&keywords=hdmi+dummy+plug

That's not Matthev said. He explain problem with IGPU that's different.

The memory type of the card is micron.
I also tried to modify the bios with polaris, but that didnt work either.
Really stucked here.

Go and download some ready made bios from other persons for your specific cards and your specific memory. The website is Anorach Tech , search there and I am sure you can find a lot of already modified bios and I have seen this card doing easily 15 Mhash after the Bios mod without problems.

Here is a link for you to check.

You have some bios modded for Hynix memory, but asking there for a micron mod should be easy, make sure to upload your original bios.

Thanks for the tip. Actually I was aware of that link but looked throughly after your advice. It worked and a dude modified my bios and now I reached to solid13.4 which is way better than my original 10.7.
THANKS again

There is a good timing for Micron.

Does your card only have 2gb of vram?
My 2gb rx560 has problems with the blockchain driver and also problems with the newer drivers when workload is switched to compute mode, unfortunately I have to leave the workload on graphics mode for it to mine reliably.
I think it's better to have 4gb or higher vram card to use the blockchain driver or compute mode with newer drivers.
I use the 17.11.4 driver and leave workload on graphics, but still get good hash speed after one click bios mod and overclock to 1300/1850.

THANKS for your responses. Really appreciated.
Driver I use ise the latest mining version from radeon.
Bios modification: I almost tried all written/given combinations with no luck.
I think I will live with this Sad

which driver that you are using? You can try Overclocking your card with massive OC, and then restart your mining software, see what happen. If you didn't get anything with it, you can try to re-modification your bios and make sure to use the right driver version.

Restart the miner each time you change your clocks. Some miners configure timing on launch based on what they see and if you raise your clocks while its running they will be wasted since the gpu just spins on empty waiting for the next tick.

If thats not the case, try overclocking with AMD's wattman (included in the "radeon software" package in driver installation). Some cards just don't get along with afterburner.

I loaded; "Radeon Software Crimson ReLive-Beta" and this is what referred in the window of after burner. But on the videos I watched during searching a solution in youtube, I saw other referred drives. Should I upload another drive as radeon drives? I have no idea.

Yes I did. Several times.
No change. Even it get's 0.1 mh worse in some cases.

It is micron.
I am jealious that other people can manage 13, which is more than 30% of mine. Sad

I just want to be successful, before adding more cards.
But still have no clue...

Did you modify bios?
