dear all,
currently im running ubuntu 16.04 lts rig, with 3x rx 580. the problem is ethash rate on dual mining (solo as well). on modded bios cards i hardly squeeze 21mh.
no matter what are the mclock/cclock values hashing varies 18-21mh/s. those values are reachble only wits asm 2 mode, solo eth mining does not help here. i really wasted lots o time no significant improve.
however at zec mining i got 330+hs per gpu which is oustanding, but what the heck can i do with eth?
What RAM brand do you have and what memory straps did you flash?
I remember when flashing UBER 3.1 timing on my samsung memory my hashrate went down vs the 1750 timings
i got xfx with samsung, which i managed to flash 1:1500 ^ and 2:1500 ^
2x sappphiro with micron first 1:1650 ^ and second 1:1750 ^
I had same problem on linux. And it was new core and need to reinstall drivers.
what you mean by new core? as per drivers i have recomended amdgpu-pro-17.40-483984, which were reinstalled already couple of times
What if you try to revert the flash to 1:1750? and see if the hashrate increases?
