Dual-mining or mining two different crypto currencies at the same time is a good way to optimize the performance and profitability of your GPU mining hardware, especially at times like now when the profitability from mining is low. Zilliqa or ZIL has added a new level of the traditional dual mining where you normally mine a GPU coin and a Memory coin on the same GPU, because it is mined for just a minute every two hours. This way you can dual-mine ETC + ZIL without losing almost any of your hoshpower for the second coin, but also you can add a third coin in the mix, a GPU-heavy coin and thus try to even further improve your profitability. Dual-mining is also possible on some ASIC miners as well such as the iPollo series of ETC/ETH miners where you can mine an Ethash or ETChash crypto coin together with ZIL, thus getting an extra 30% higher profit compared to just normal mining.
Kaspa or KAS is an interesting and still highly unnoticed project that is just recently starting to gain attention not only form miners, but from investors as well. A couple of days ago we have discussed how you can start mining Kaspa (KAS) and since then the coin has pretty much doubled in trading price and was going up in a market conditions where most other crypto coins were going down. So, if you still haven’t checked out Kaspa (KAS) and its very fast block times and transfer on-chain, then you should do so as it will become even faster in the near future. Also, do not miss your chance to mine some coins now as well and make some really nice profit in the future!
We are not going to focus on KAS now, here we are going to be talking about Dual-Mining ETC and KAS as well as Tripple-Mining ETC + KAS + ZIL. Etereum Classic (ETC) uses the memory heavy Etchash algorithm while Kaspa (KAS) relies on the kHeavyHash algorithm for mining which is a GPU heavy one, so they are a great combo together for dual-mining and adding Zilliqa (ZIL) on top of these two makes a great mining threesome for optimal performance and profit. You can of course use not only ETC, but other Ethash or ETChash crypto to pair up with KAS and ZIL for triple mining, so the choice is up to you. To answer your question before you ask, yes, we are currently mining ETC + KAS + ZIL on our Nvidia mining GPUs.
We are going to focus on using lolMiner for dual-mining and triple mining here (latest version 1.62), although other miners such as Gminer and Bzminer for instance also support dual and/or triple mining and the procedure there is similar, although the command line to run the miner might be different. Currently we like the stability and performance of lolMiner the best as far as Kaspa mining is concerned, but feel free to use a different miner if you prefer it over lolMiner. The examples below use the Ezil.me mining pool for Dual mining ETC + ZIL and the WoolyPooly pool for mining KAS, other mining pools should work, but may require a bit of a different configuration settings. Do not forget to replace ETC_WALLET, ZIL_WALLET, KASPA_WALLET and WORKER with your own wallets for the respecitve crypto currency as well as the name or number of your machine as worker.
ETC + KAS Dual Mining:
lolMiner.exe --algo ETCHASH --pool eu.ezil.me:3333 --user ETC_WALLET.WORKER --dualmode KASPADUAL --dualpool pool.eu.woolypooly.com:3112 --dualuser KASPA_WALLET.WORKERETC + KAS + ZIL Triple Mining:
lolMiner.exe --algo ETCHASH --pool eu.ezil.me:4444 --user ETC_WALLET.ZIL_WALLET.WORKER --enablezilcache --dualmode KASPADUAL --dualpool pool.eu.woolypooly.com:3112 --dualuser KASPA_WALLET.WORKER
Now, although we are showing you dual and triple mining configurations, it is really pointless not to take advantage of the triple mining option as it will only benefit you even more as ZIL mining hardly affects the mining performance of the two other coins and the extra profit it will bring you is definitely worth it!
So, with the above settings the miner will try to maximize the ETC mining hashrate and fill in the available GPU resources with some KAS calculations, thus you will be getting pretty much the same hashrate for ETC and about 1/4 to 1/5 of the usual KAS hashrate compared to KAS only mining. On a rig with 6x RTX 3080 GPUs that do 570 MH/s ETC only or 5500 MH/s KAS only we are getting around 565 MH/s ETC and around 1400 MH/s KAS hashrate in triple mining plus an extra up to 30% profit from the mined ZIL in triple mining mode (without the ZIL in dual mining only). On different GPUs your results may vary of course, especially on slower video cards, but the extra hashrate and profit should still be worth it.
In terms of the mining settings, you need to just return the GPU clock to its default value if you were downclocking it for ETC/ETH mining previously, the memory clock and the power limit levels should remain the same as for ETC/ETH mining. You could of course increase the power limit in order to get some extra hashrate for KAS, but that will also lead to increased power usage as well. The idea is to keep the ETC/ETH mining settings including the power limit, so that you would actually get more mined with the same power usage as if you were just ETC mining for instance.
