The Rigel Nvidia GPU miner is a newcomer among the mining software solutions for GPU miners and more specifically for Nvidia GPU mining rig operators, but it is doing quite well in terms of competing with other older and more established and widely used miners. It does not support that many algorithms, but it is quickly introducing support for ones that are gaining a lot of user attention and the performance is really good. Not to mention that the miner comes with a nice text-based terminal user interface, is quite easy to use and comes with the right number of features including full overclocking set for the GPUs.

The Rigel miner also supports dual mining with Zilliqa (ZIL) as a means to further increase mining profitability as this dual-mining mode supports not only ethash and ethash, but any single or even dual algorithm combination + ZIL. Triple mining is supported for ethash + kheavyhash + zil and etchash + kheavyhash + zil, but that one is not actually that interesting of a mode compared to the dual-mining any algorithm with ZIL. The reason for that is due to the way ZIL is being mined – just a very short period of time every two hours, so essentially you retain the full hashrate of the main algorithm for mining the rest of the time and the extra profit from the mined ZIL is not something to miss.

In the last few versions ZIL mining was broken apparently, though the latest update of Rigel 1.3.4 brings it back working properly, so we are going to do a quick overview on how you can dual-mine Kaspa (KAS) with Zilliqa (ZIL), so that you can maximize your profit and get more than just single mining KAS. Now, Kaspa (KAS) and its kheavyhash algorithm is GPU-intensive, so you can optimize performance with a significant reduction in power usage compared to the normal settings for your video card. On the other end however you have Zilliqa (ZIL) that is a memory-intensive algorithm that just like Ethereum or any other Ethash-based crypto coin like ETC that is still mineable doesn’t need a lot of GPU power, but can benefit from maximum clock of the video memory.

So, how to combine these two seemingly opposite algorithms for dual-mining while getting optimal performance mining both? This is what we are going to take a look at now with the below example for dual-mining KAS + ZIL on an Nvidia GeForce RTX 3070 GPU, followed by explanation what and why is being used like that (the example is for windows, but the same settings should work on Linux as well). Make sure that in the example you set YOUR_KASPA_WALLET, YOUR_ZIL_WALLET and YOUR_WORKER_ID in order for the mining to properly start and you get the mined coins credited. We are using WoolyPooly as KAS mining pool and ShardPool for ZIL, though others should work as well (make sure you have the right settings for them):

rigel.exe -a kheavyhash+zil ^
-o [1]stratum+tcp:// -u [1]YOUR_KASPA_WALLET ^
-o [2]zmp+tcp:// -u [2]YOUR_ZIL_WALLET ^
-w YOUR_WORKER_ID --log-file logs/miner.log ^
--cclock 300 ^
--lock-cclock [1]1710 --lock-mclock [1]807 ^
--lock-cclock [2]1200 --mclock [2]1000

Now, the cclock 300 option above sets the GPU clock offset in order for the video cards graphical processor to run at a lower voltage (it is set for all coins mined), do note that the 250-300 setting generally works well on most RTX 3070 GPUs, so test on your mining hardware and find what works stable for you. Since the first coin we are mining is KAS and we have it marked with [1] above then the lock-cclock [1]1710 and lock-mclock [1]807 options refer to the video card settings for Kaspa mining, setting the GPU clock locked at 1710 MHz and the memory clock to the minimum supported 807 MHz in order to reduce the power usage from the memory that we do not need much for the kheavyhash algorithm. The other line lock-cclock [2]1200 and mclock [2]1000 refers to the GPU settings for the second coin we are mining and in this case this is Zilliqa where we don’t need a higher clocked GPU, but could use a +1000 MHz overclock of the video memory over its stock settings in order to get the hashrate up to about 60 MH/s for an RTX 3070 GPU.

You will notice that mining with the settings used in the example above on RTX 3070 GPUs you will be getting around 90-95 Watts of power usage per GPU while mining KAS and when the ZIL switch occurs the different settings that will be applied will bring up the power usage to about 115-120 Watts (these can vary from GPU model to GPU model). So, there will be a slight increase of power usage for a couple of minutes in total on a daily basis and thus there will be not much of a difference in the overall power usage. While mining ZIL you will not be mining KAS, but again the switch is for a short period of time and the earnings for the mined ZIL should be able to compensate for the time you will not be mining KAS.

But why not leave the GPU settings for KAS mining for ZIL mining as well some of you may ask? Well, the answer is pretty simple – the ZIL mining performance will be very low due to the low memory setting we are using to save power when mining KAS. While Kaspa can be mined without performance loss at 807 MHz for the video memory, that operating frequency will result in just around 5 MH/s of hashrate per RTX 3070 GPU compared to round 60 MH/s when the memory is overclocked with 1000 extra MHz over its stock frequency on the same GPU. So, while you might be saving a little bit of power the hashrate will be so low that you might not be able to send even one share during the ZIL mining timeframe and thus you might just be wasting your time, unlike what the GPU can do at 60 MH/s. Just as a reference, in a single ZIL mining period (every two hours) a 6x RTX 3070 GPU mining rig should be able to currently mine 1-2 ZIL (depending on the number of shares you get).

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 hashpower 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 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 --user ETC_WALLET.WORKER --dualmode KASPADUAL --dualpool --dualuser KASPA_WALLET.WORKER

ETC + KAS + ZIL Triple Mining:
lolMiner.exe --algo ETCHASH --pool --user ETC_WALLET.ZIL_WALLET.WORKER --enablezilcache --dualmode KASPADUAL --dualpool --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.

Kaspa (KAS) is a very interesting crypto project that has been mostly flying well under the radar, but it is starting to get the interest it deservers lately. KAS is a proof-of-work cryptocurrency which implements the GHOSTDAG protocol – a protocol that does not orphan blocks created in parallel, but rather allows them to coexist and orders them in consensus. This generalization of Nakamoto consensus allows for secure operation while maintaining very high block rates (currently one block per second, aiming for 32/sec, with visions of 100/sec) and minuscule confirmation times dominated by internet latency.

Kaspa (KAS) being a PoW coin can be mined and mining is based on kHeavyHash, a modified form of the “optical-miner” ready HeavyHash algorithm. kHeavyhash utilizes matrix multiplication that is framed into 2 keccacs. kHeavyHash is energy efficient, core dominant (requires higher GPU clock and not affected as much by memory) and can be successfully mined by GPU with FPGAs and future specialized mining equipment also possible in the future. The blockDAG architecture of Kaspa with rapid block rates allow more mining decentralization and enables effective solo-mining even at lower hashrates. KAS was launched in November of 2021 with no pre-mine, zero pre-sales, and no coin allocations. The total supply of Kaspa is 28.7 Billion coins with an emission schedule that halves once per year via smooth monthly reductions by a factor of (1/2)^(1/12). The current block reward is 329.63 KAS and the circulating supply is almost half of the total supply with a total market cap of around 50 million USD.

Kaspa (KAS) can be mined on a number of mining pools with the largest one being WoolyPooly, though you might want to check out some of the smaller ones in order to distribute hashrate such as ACC Pool and HashPool. It can be mined on both AMD and Nvidia GPUs with a number of popular miners supporting the kHeavyHash algorithm that the coin uses such as LolMiner, GMiner, BZminer, SRBminer, Team Red Miner and KaspaMiner.

Our preferred GPU miners for Nvidia GPUs are LolMiner and GMiner, and you might want to make sure you are with more up do date video drivers for maximum performance. Also, you might want to lower the memory clock and increase the GPU clock as this is a GPU intensive algorithm and higher clocks for the GPU and increased power limits will get you much more performance boost than overclocking the memory. This also means that the power usage of GPU mining rigs optimized for Kaspa mining will be higher than what you used for Ethash/ETChash mining, though you can remain at the same lower power levels with a bit reduced hashrate of course.

A few crypto exchanges are already supporting KAS trading, these include TxBit, ExBitron, MexC and TradeOgre. There has been a spike of interest and a bit of a price hike in the last few days, so mining profitability is also up with Kaspa getting in the list of the most profitable coins to be mined at the moment.
