Hi guys.
I was wondering, if there is someone mining ether on rx 560 that managed to get stable 14+ Mh/s?
I got rig with 6x rx 560 sapphire pulse 4gb
After day and half testing i was able to get approximately to 13 - 13.9 while base was aprox 10.5-11.5 per card.

Its nearly impossible to get cards more suited for mining these days, so i was thinking there must be someone with more experience than me that got better results with these

Also, 2 little side questions.

1. These cards seems to have some warm period up before going to full speed, i start mining and they are around 9 Mh/s and then they go up after while, is that normal?

2. Performance seems to fluctuate somewhat, sometimes even 3 Mh/s, which is quite a lot considering maximum is around 14

I also mine a little on my gaming PC with gtx 1060 and none of this is happening there.

so i am screwed again.
MSi afterburner or other software i tried wont let me OC my cards. Either i change anything and as soon as i press apply all changes reset to default, or (on newer drivers) can OC a card, but as soon as i do it others underclock so hard its almost like they are turned off.

I was thinking of bios flashing, but if i am not mistaken, from drivers version 16.2.X there is signature check for card bios...
Thing is, windows wont let me install any drivers older than 17.X.X as it takes them inferior to the default windows driver.
Also, i have red somwhere, that cards with polaris chip - which mine is - requires at least drivers 16.6.X

I have tried to bypass signature check using this guide:
https://bitcointalk.org/index.php?topic=1806196.0
but i failed miserably, it appears, that it cannot be done with these new drivers, wven when i restarted with disabled driver signature enforcement my installation failed because of failed signature check on the atikmdag.sys

do yoiu guys think that some way of overclocking exists for me?

I have decided to go with windows as i am most familiar with it... if i will not be able to get it working i will try different options... or later once i get more experience and get into fine tuning performance
Anyhow, thanks for the tip

HA !
It finally works !!
Someone already mentioned the 4g option to me before, but i was not able to find it in bios... coz i did not have it updated... now i feel really stupid... half an hour action and i spent 2 days on it

So now just tweaking issues ahead of me it gives me 70-ish Mh/s and im hoping for 80-90 after some overclocking...

Bad thing is, if i use MSI afterburner to move my memory clock, it adjusts just one of the cards and the rest falls down to 300Mhz instantly.
 on different drivers i was not able to OC with some software at all...
I guess that leaves me with bios flashing, which i never done before. Im sure i will google some guide, but if you have some general tips, or something i should be careful about, i will happily take your advice

Hello guys, i have recently started mining ether on my gaming pc and few days back i decided i will build a rig... since then, i am having nightmares

Got all parts:
6x sapphire pulse rx 560 (i know, not great card, but i could not get any better)
MB Asus prime H270 plus
processor Intel Pentium G4400
+ some RAM, risers and evga PSU to run it all.

I have set up the rig on win 10.
Set virtual memory to 16GB

Now all cards are detected by windows (but four of them in PCIEX1 slots are giving me warning msg:This device cannot find enough free resources that it can use. (Code 12))

Problem is, when i want to start mining. i use Claymore (Claymore's Dual Ethereum+Decred_Siacoin_Lbry_Pascal AMD+NVIDIA GPU Miner v9.6 to be specific)

If i have just 4 or less cards connected, claymore detects them all and mines with no issue - as far as i noticed, it does not matter which slots i use.

BUT if i plug 5th or 6th card, claymore is suddenly able to detect just cards in full PCIEX16 slots and i have no idea why.

I was suspecting crossfire, and spent quite some time trying to find out how to turn it off, as the option to turn it of just werent where it should be... then i found out in GPU-Z, that it is disabled on my cards, so i guess rx 560 does not support it at all(?)
I have tried several versions of drivers, even some crazy combining 2 version of drivers according to some guide, but nothing helped.

I would be really grateful for any advice as i have spent basically all my free time in past three days on this and i am starting to go crazy

Ok, so i tried bunch of other stuff to find a way to disable crossfire - nothing worked... then i realized, GPU-z should show status of crossfire and it turns out, i have it disabled on both cards in PCIEX16 (i have unplugged the other cards for now)

So, if crossfire is disabled, why claymore still detects only cards in PCIEX16 and not cards in  PCIEX1 slots?

Still if i plug in 4 cards (1 PCIEX16 and 3 PCIEX1) it all works fine...

Id be grateful for any tips.... for now ill just set up 4gpu rig and go to sleep, i am exhausted and got to work tomorrow :/

Do you have some tip on how to do that? All guides i found were showing option to diable crossfire under Gaming > Global settings > Crossfire....
Yet i do not have this option at my radeon settings, i have tried multiple versions of drivers, currently i am running 17.4.4 but i have not seen that option in any version i tried.
Is there some other way to turn of crossfire for good?

Yes, without that, not ecen windows was able to detect cards properly... i suspect crossfire has something to do with this issue, as if i connect more cards, only those two in full slots are working

Hey there, im quite new into mining- I recently started to mine on my gaming PC just for fun and then i decided to build a rig...
So i got all the parts and six rx 560 (as i could not get any better cards due to global shortage)... and that is when my nightmare started.

I run the rig on win10. system detects all the cards with no problem... well after few but i managed that
but once i start claymore, im done for.
If i got only 4 cards plugged in, everything works fine, but as soon as i plug in 5th or 5th and 6th card, claymore is suddenly able to detect just 2 of them.

I have spent better part of last two days trying to find some solution, but i got nothing. Tried countless drivers, restarted the rig a million times, even tried other miners despite the fact that i like claymore the most...
nothing

If anyone got any idea what could help, please let me know.
