You probably need to update to the AMDGPU Pro compute mining drivers.

Try mining a coin with a small Dag size like UBQ to see if it's the Dag file size issue that's solved by the mining drivers.
Topic: Huge Difference in Eth hashrate between W10 and Ubuntu (Read 213 times)
Hello, I'm having trouble with my hashrate using claymore's miner. Im using Ubuntu for my mining rig, but W10 to modify BIOS and testing. The problem is that when I put my GPU in my mining rig, I hash at 23.735 MHs/s, while on windows I'm hashing at 29.8MHs/s. This difference is huge! Do you have any solutions or suggestion what might be the problem?
My mining rig is as follows:
Motherboard: AsRock H110i pro BTC+
CPU: Intel Celeron G3900
RAM: Kingston DDR4 2133Mhz 4GB
PSU: Corsair HX 1200
GPU: MSI RX580 4GB Armor
GPU BIOS:
Changed timings. 1:1500 timing value copied to 1:1500 to 1:2000 and 2:1500 timing value copied to 2:1500 to 2:2000
The rest of the modification can be seen in the figure attached.
