Same GPU,same bios but different hash on Ethos/Windows. Pls help me!!!

[Kornbluth]

Asus rx 470 mining edition on windows claymore 10.2 hashrate 29.3 Mhs.

start.bat

setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100

Same gpu, same bios, same setting (i think) on ethos 28.2 Mhs

what am I doing wrong

[0xcosmos]

its just a difference of hashrate between different os
you will need to fine tune card in ethos to get those hashrate
but i will still suggest to stick with windows

[yarustr]

Windows or linux they will produce same hashrate. Linux will be more stable. You just need to make correct settings. ccminer has intensity settings. If you do not set it it will get default value . But to get max hash you should increase it .

Ethos actually is pretty stable for mining.

Now there is a tool for auto overclock testing/tuning check:
