Hi All

Having modded my AMD bios's using Windows to about 30mh per card (180mh on a 6 card rig) I then setup linux with this driver, and i am getting only 177mhs

Does this sound normal? Difference of 0.5 mh's per card for linux?

One thing i did notice is windows every now and then would have a dramatic drop, and then increase back to the expected speeds, where as this seems far more stable at one speed?

Thoughts on all of this?

mostly the windows has more frequent state changes whereas linux isn't doing that. monitor gpu clocks using below commands for active core and memory frequencies.
cat /sys/class/drm/card0/device/pp_dpm_sclk | grep '*'
cat /sys/class/drm/card0/device/pp_dpm_mclk | grep '*'

replace card0 with yours
