I still can't understand the benefit of those double miners. My point is that if you want to separate the hashpower on each rig , you can do it by managing which cards will mine CoinA , and which - CoinB..
What am I missing here ...
The idea is to mine one primary algo and at the same time mine another algo for different crypto coin.
The primary algo, would have more or less the same output as in single mining mode.
The secondary algo, would utilise wasted capacity on the GPU (980 or 970 or 960 or 950 or 750), it would have lower hash output.
This boosts the daily productivity of your GPU and also gives greater accumulation in two different cryptos.
The developer, would get daily fee of 1% or 2% of daily hash output for ongoing technical support and reward them for spending their precious waking hours doing all that crazy coding.
This is copied from the Legendary AMD software developer called Claymore
Claymore, recoded the Ethereum mining software for AMD GPUs, raising the hash output by 5%, but Claymore also recycled the unused GPU output to mine a second algo (Decred).
This meant, AMD GPU owners got a 5% boost on the main algo (Dagger used to mine Ethereum) and 14% extra profit each day from the Decred algo.
For this software, Claymore designed a pay as you go system, 1% developer fee for single mining mode and 2% developer fee for dual mining mode.
Every hour, the Claymore AMD miner will disconnect from your pool and will mine Ethereum's Dagger algo to Calymore's wallet address.
Total daily single mining mode fee: 14 minutes 24 seconds.
Total daily dual mining mode fee:28 minutes 28 seconds.
This is 36 seconds in single mining mode and 72 seconds in dual mining mode each hour.
In terms of Decred, their is no fee on the Decred hash output on AMD Claymore miner, which saved Claymore a huge headache in coding and finding pools for second algo.
Essentially, AMD GPU owners made an extra 19% and gave Claymore 2% of those profits back for doing all that hard work for them!
There is nothing like it for Nvidia GPUs and SP_ is trying to ride to the rescue of Nvidia GPUs owners
