I've been able to get a much higher hashrate on other systems. These are the steps I've taken so far, getting ~ 17Mh/s.
Description: Ubuntu 17.10
Kernel: 4.13.0-36-generic
- Install amdgpu-pro-17.40-492261 (used the –compute flag. This is the only way my machine will boot)
-
Flashed the BIOS (BIOS was found online)
atiflash -p -f 0 Anoraks_Sapphire RX 570 Pulse 4GB Hynix Elpida_memshift-1500.rom -
Ran this for OC
sudo bash -c 'echo 5 > /sys/class/drm/card1/device/pp_sclk_od'
sudo bash -c 'echo 15 > /sys/class/drm/card1/device/pp_mclk_od' -
Claymore flags: -epsw x -mode 1 -ftime 10 -asm 1 -etha 0
I've also tried a kernel 'pre spectre meltdown' with no effect. Any help or advice would be much appreciated 🙂 will send some ETH for a solution!
Update: I have noticed the SCLK & VDDC fluctuating while mining. Power goes from 95W to 105W and SCLK goes from 988Mhz to 1070Mhz…
Changing to Ubuntu 16.04 and Kernel 4.10 does not do anything.

its a krenel issue, get ubuntu 16.04.03 LTS with kernel version 4.10.0. any newer kernel and you will get up to -8 mh/s.
