Hello,

How i set a max hashrate / mining  speed.




For example :

I want max 183 total speed for 6 r9 390x

How i do that?

Thanks

Solo mining Eth at a pool - simply follow the readme file.

Dualmining, depends whether you want to maximise ETH or you want more SC or Decred.

More Eth with AMD cards - set all cards to slow mode -etha 1,1,1,1,1,1,1

Set around -dcri 22 for SC or Decred- run for 24 hours and divide shares by 1440 minutes to find out your baseline average.

Then, experiment for yourself with SC and Decred settings!

More SC - Decred

Just try higher -dcri settings out to find what you happy with in terms of extra SC or Decred coin accumulation.

Overclocking - just google the web for the professional reviews on you specific model/manufacturers' GPUs overclock benchmark and use them as a guidelines.  


Hello,

Thanks, i hace 6 of r9 390x, but in the night  the vat crash because the speed mining, more of 220 hash, this is cool for i  have 4x of r9 390x in a gold power supply of 1300 watts and i think that make crash my claymore bat. So, i need to keep my hash rate on 180 , i try -li command but it decrease so much my speed ( to 150 ) other way to keep my hash in 180 ( no more of 180 ) or orher way of reduce the power need?

Thanks

Well,

It is max watts (without overclock) is 275watts per card 1650watts for 6 cards.

Solo mining ETH at pool is around 1020 watts.

Dualmining ETH with Decred or SC is around 1266watts.

Depending on overclocking, it can be higher.

Motherboard 30 watts, CPU 65watts and other bits may be another another 40 watts.

Solo mining ETH is around 1155 watts.

And Dual mining is around 1401 watts.

I'm not sure how old you PSU is, but factor in 10% to 5% capacitor loss rate per year:

PSU after 1 year 10%=1190watts
PSU after 2 years 15%=1105watts
PSU after 3 years 20%=1040watts

Finally, did you check the PSU manual to check the max amps on the 12volt rails and if you have more than one 12volt rail.

It is a lot more complicated doing the connectors, when you have multiple 12volt rails.



There is no such thing as 10% 15% 20% loss after 1-2-3years that is a myth. Have 4year and 2.5year psu's running 24/7 since I bought them, no difference in efficiency.

Perhaps, here is some research on it:

You can then, publish comprehensive research disproving this alleged Myth about:

ELECTROLYTIC CAPACITOR DEGRADATION

Nobody, recommends skimping out on PSUs or running them at full load - efficiency tends to best around 50% on many high quality PSUs:

Some bigger miners, buy and run dual PSUs to have 50% loads when mining!

 Just get an evga with a 7 or 10 year warranty and if you see high degradation then its all good.
