Guys and Gals, I need your help
I have 2 Sapphire Nitro+ RX 580 8GB (11265-01-20G). One with Samsung memory and the other with Hynix.
I began modding the Samsung one and now is at 30+ MH/s. Switched to the Hynix one, and after modding, it is only at 19MH/s (without modding was 20 MH/s). The BIOS switch is in the correct position.
I have tried the following using Polaris (1.6.6)
* 1:1750 to 1:2000
* 2:1750 to 2:2000
* 1:1750 to 1:2000 and 2:1750 to 2:2000
The samsung one has been working perfectly modding only 1:1750 to 1:2000 (didn't have to patch driver) and some settings with MSI-AB.
Any help or suggestions would be appreciated.

from my understanding, on hynix the 1:### does nothing. (i never touch these.)
Any other suggestion?

With this set...
How many MH/s should show with this set??
with cclock 1200 and mclock 2100 that should give you near 30.
GPU-z (shows Hynix)
With the latest settings
I installed newest drivers from AMD (November 2017) and it hasn't improved.
Now that you asked, I don't know if it's Samsung or Hynix.
GPU-z show that the memory is Hynix but PBE shows that has Samsung and Hynix. Is that normal?
We did it, now is @28.9 MH/s (before applying any change in MSI-AB). I flash each BIOS with Originals and started from 0. Upgraded the version of AMD Settings and change from gaming to computing and make sure that Crossfire was disabled.
I want to thank you for all your suggestions.
Yes, I had blockchain drivers (from Aug 23) before. The Samsung one was giving me 30MH/s without problems. I just installed version 17.11 (Nov 10).
samsung cards do MUCH better than hynix.
(I have seen samsung top out at 32mh/s. I have seen hynix best case at 30mh/s)
So I think you're in the right ballpark now.
I think that strap can go to ram speed 2150 and you'll be in the mid 29's.
I moved to a linux based mining software and it's far more stable. (currently sitting at 4 days with zero restarts on 27 cards (3 rigs))
in windows, I'd have the miner reload periodically, I'd have the computer restart due to windows updates, and various buggy behavior due to drivers loading funny.
If you're scared of linux, check out simpleminer.
takes like 20 minutes to get working and requires NO linux experience.
Write the program to a USB stick. change a *.txt file on the USB stick to your email address.
Done.
Then the rest (claymore config) is all done via the simpleminer webpage.
The card power settings in simpleminer are easy too. all done on the webpage.
my recommended settings:
voltage 890
clock 1200
GPU memory 2100 (hynix)
GPU memory Powerstage "2"
I have been runing the rig for 330 hours without problems.
31 MH/s - 74W
30 MH/s - 87W
Once again, thanks @suthek for your help.
I'm running Adrenaline driver with compute workload enabled.
