am i the only one who is getting lower hashrates compared to some weeks ago?

For ETH i'm getting only 19 mhs in SMOS while windows is hashing almost 28 mhs, for XMRv7 i'm doing 640 Hs while on windows is doing almost 800 Hs ... Of course i'm using same miner (Claymore, XMRig) and same OC.

What i've tried:
-Testing with only 1 GPU connected
-Adding more RAM(from 4GB to 8GB)
-Burning SMOS ISO again to the USB
-Removing undervolt
-Flashing BIOS with different timings
-Different risers
-Different Motherboard

Nothing works ...


Btw i just noticed, i have to rigs and they have differents drivers and kernel ...

The rig that works without issues (also RX570 but NITRO+ instead MSI)
Linux Kernel: 4.11.0-kfd-rocm-rel-1.6-148
AMDGPU: 17.30-465504

The one with problems (MSI RX570 RIG)
Linux Kernel: 4.11.0-041100rc3-generic
AMDGPU: 16.60-379184
