this was tried on hiveos vega 64 these are my results so far

Okay seems like reducing rc gave me a slight boost

rc reduced to 45 from 47 gave about 0.7 mh rise
increased faw to 19 from 16 increased hash rate by 1mh, tried 22 and it shutoff the cards

seems like faw and rc are related changing only faw or only rc has no diff on hash

if rc goes below 45 it shuts of the cards
had to reboot

so far found how low rc can go and how high faw can go
gonna test if increasing rc has any results

turns out increasing rc reduced the hash so dont do that

changes to rp making no diff but increase by 4 from default seems to reduced hash

increasing rrd seriously reduced has like to 31mh

turns out increasing rfc reduces hashrate
and no point decreasing rfc value still no effect

increasing rtp also seems to reduce hash rate and reducing it to 1 from its default 5 is of also no use

increasing cwl has no effect tested till value of cwl 15 when cwl was set 20 it shut off the cards but until then had no effects to hash

will update this list when am done using the other two options remaining they are "wrts" "wrtl" "wr"

I played with this tool during the weekend on Vega.
But to be honest I did not see any hashrate increase under CN algos.
I'm not an expert on timings, but I should see at least 1-2% increase when changing CL 20->19

That was the first time I put a Linux AMD system together and I am struggling with the different kernel and driver versions not working together.
The biggest problem is the GPU freq is affected by the voltage.
If I set in PPT P7 1600 950 then the GPU runs only at around 1400@950mV. If I increase the voltage the clock goes up, but quickly reaches TDP.
Also if I try to trick it and set P7 1700@950 then if load changes freq spikes up and card freezes obviously.
Tried with 3 different kernels and one is worse than the other.
Maybe I should try other than the 18.50 amdgpupro?

i got no results on reducing cl and when i tried increasing it , it shutoff the rig
