Re: SRBMiner Cryptonight AMD GPU Miner V1.6.6 - with algo switching support
Here's a nice little tip on how to increase your hashrate even more :
Example for Vega56 doing normalv7 algo :
1.Put --enableduplicategpuid in start.bat at the end of line ( SRBMiner-CN.exe --config config-normalv7.txt --pools pools-normalv7.txt --sendallstales --enableduplicategpuid )
2.Set gpu in config-normalv7.txt :
What was done here? When using 2 threads , the best value for intensity is 123. By enabling the usage of duplicate gpu id, you make 2 separate threads for 1 gpu, but one has value 123-1, the other 123+1.
This method can be used on any GPU, you just need to experiment with the intensities.
I tried this on my Vega 64's and saw a nice little bump for not doing much. I was able to squeeze out between 15 and 20h/s per card. So that really adds up pretty quickly. Now I am going to cry and say it messes up my monitoring Example for Vega56 doing normalv7 algo :
1.Put --enableduplicategpuid in start.bat at the end of line ( SRBMiner-CN.exe --config config-normalv7.txt --pools pools-normalv7.txt --sendallstales --enableduplicategpuid )
2.Set gpu in config-normalv7.txt :
Code:
{
"cryptonight_type" : "normalv7",
"intensity" : 0,
"double_threads" : true,
"gpu_conf" :
[
{
"id" : 0,
"intensity" : 122,
"worksize" : 8,
"threads" : 1
},
{
"id" : 0,
"intensity" : 124,
"worksize" : 8,
"threads" : 1
}
]
}
"cryptonight_type" : "normalv7",
"intensity" : 0,
"double_threads" : true,
"gpu_conf" :
[
{
"id" : 0,
"intensity" : 122,
"worksize" : 8,
"threads" : 1
},
{
"id" : 0,
"intensity" : 124,
"worksize" : 8,
"threads" : 1
}
]
}
What was done here? When using 2 threads , the best value for intensity is 123. By enabling the usage of duplicate gpu id, you make 2 separate threads for 1 gpu, but one has value 123-1, the other 123+1.

I now see duplicate GPU's.
