RigelMiner v1.3.4 – dual KAS + ZIL mining on Nvidia GPUs

The Rigel Nvidia GPU miner is a newcomer among GPU mining software solutions, or more specifically, for Nvidia GPU mining operators, but it competes quite successfully with other, older and widely used miners. It doesn’t support many algorithms, but it quickly introduces support for those that get a lot of user attention, and its performance is really high. Not to mention that the miner comes with a nice text-based terminal user interface, is quite easy to use and has the right amount of features, including a full overclocking suite for GPUs.

The Rigel miner also supports dual mining with Zilliqa (ZIL) as a means to further increase mining profitability, since this dual mining mode supports not only ethash and ethash, but also any combination of one or even two algorithms + ZIL. Triple mining is supported for ethash + kheavyhash + zil and etchash + kheavyhash + zil, but this mode is not as interesting compared to double mining any algorithm with ZIL. The reason for this is the way ZIL is mined – only a very short period of time every two hours, so the rest of the time you keep the full hash of the main algorithm for mining, and the extra profit from mined ZIL is not to be missed.

ZIL mining has been broken in the last few versions, although the latest Rigel 1.3.4 update brought it back up to speed, so we’ll do a quick overview of how you can mine Kaspa (KAS) with Zilliqa (ZIL) to maximize your profits and get more than you would with single KAS mining. So, Kaspa (KAS) and its kheavyhash algorithm are GPU-demanding, so you can optimize the performance by significantly reducing the power consumption compared to your video card’s normal settings. Zilliqa (ZIL), on the other hand, is a memory-intensive algorithm that, like Ethereum or any other Ethash-based cryptocurrency like ETC that can still be mined, does not require much GPU power, but can benefit from maximum video memory usage.

So how to combine these two seemingly opposite algorithms for dual-mining and get optimal performance when mining both? That’s exactly what we will look at in the example of dual KAS + ZIL mining on a Nvidia GeForce RTX 3070 GPU, and then explain what and why it is used that way (the example is given for windows, but the same settings should work in Linux as well).

Make sure you set “YOUR_KASPA_WALLET”, “YOUR_ZIL_WALLET” and “YOUR_WORKER_ID” in the example so that mining will start correctly and you will be credited with the mined coins. We use WoolyPooly as pool for KAS mining and ShardPool for ZIL mining, though others should work too (make sure you have the right settings for them):

rigel.exe -a kheavyhash+zil ^
-o [1]stratum+tcp://pool.woolypooly.com:3112 -u [1]YOUR_KASPA_WALLET ^
-o [2]zmp+tcp://eu1-zil.shardpool.io:3333 -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 speed offset to make the graphics card GPU work at a lower voltage (it is set for all mined coins), please note that the 250-300 setting usually works well on most RTX 3070 GPUs, so test it on your mining hardware and find what works for you stably. Since the first coin we mine is KAS, and we noted it [1] above, the lock-cclock [1]1710 and lock-mclock [1]807 options refer to the video card settings for mining Kaspa, setting the GPU clock frequency locked to 1710 MHz and the memory clock frequency to the minimum supported 807 MHz to reduce the power consumption from memory, which we do not really need for the kheavyhash algorithm. The other line lock-cclock [2]1200 and mclock [2]1000 refers to the GPU settings for the second mined coin, in this case Zilliqa, where we don’t need a GPU with a higher frequency, but we could use a +1000 MHz video memory overclock compared to the stock settings to raise the hash rate to around 60 MH/s for the RTX 3070 GPU.

You will notice that when mining KAS with the settings used in the example above on RTX 3070 GPUs, you will get about 90-95W of power consumption per GPU, and when ZIL switching happens, the different settings that will be applied will increase power consumption to about 115-120W (they may vary depending on GPU model). So there will be a small increase in power consumption for a couple of minutes total each day, and so the difference in overall power consumption will be negligible. When mining ZIL, you will not mine KAS, but, again, the switch is for a short period of time, and the earnings for the mined ZIL should compensate for the time during which you will not mine KAS.

But why not leave the GPU settings for KAS mining and for ZIL mining, you ask? Well, the answer is quite simple – ZIL mining performance will be very low because of the low memory settings we use to save power when mining KAS. While KASpa can be mined without performance loss at 807 MHz video memory, that operating frequency will only provide about 5 MHz/s of hash rate on the RTX 3070 GPU compared to 60 MHz when overclocking the memory at 1000 additional MHz compared to the standard frequency on the same GPU. So while you will save some power, the hash rate will be so low that you won’t be able to send even one share per ZIL mining time and therefore just waste time, as opposed to what the GPU can do at 60 MHz/s. For comparison, in one ZIL mining period (every two hours) a mining rig with a 6x RTX 3070 GPU should be able to mine 1-2 ZIL (depending on the number of shares you get).
