Kaspa (KAS) has been doing nice going up in worth and attracting the eye of extra miners in addition to merchants and traders and the undertaking remains to be not listed on any of the massive exchanges. Kaspa has the know-how to evolve in one of many high Layer 1 crypto tasks sooner or later and is among the not that many Proof of Work primarily based promising tasks that would additionally deliver again profitability for GPU miners. So, a reminder to test KAS out in the event you nonetheless haven’t achieved so already, don’t say we didn’t warn you. In case you are a miner, then you need to most undoubtedly check out Kaspa and their GPU-heavy mining algorithm and doubtless get in early and begin mining. Kaspa has a discount of the mined cash each month and the issue goes up as an increasing number of miners be part of. However now, allow us to focus extra on mining Kaspa (KAS) and how one can optimize the settings of your Nvidia GPUs for optimum efficiency or for optimum effectivity among the extra fashionable Nvidia GPUs used for mining.

We’re going to be utilizing the newest lolMiner 1.63 as mining software program for the examples beneath, displaying you the command strains and explaining what parameters to set and why. LolMiner is offered for each Home windows and Linux and is part of most mining-based working programs corresponding to HiveOS, so you may nonetheless use the guidelines beneath though establishing extra parameters in a Linux-based mining OS could be a bit totally different in comparison with simply working the mining software program itself. Anyway, since KAS makes use of a GPU-heavy mining algorithm referred to as kHeavyHash you don’t want numerous video reminiscence by way of capability or bandwidth, so even a bit older higher-end Nvidia GPUs can carry out fairly nicely in time period of efficiency with surprisingly good energy effectivity when correctly tweaked. Alternatively, you may also Triple-mine ETC + ZIL + KAS (or one other Ethash or ETChash crypto coin, not solely Ethereum Traditional) for optimized and extra diversified mining portfolio.

We’re beginning up with Nvidia GeForce RTX 3090 and what settings to make use of for optimum efficiency with decreased energy utilization. Because the RTX 3090 has numerous high-speed GDDR6X video reminiscence and also you don’t want it for KAS mining we’re going to decrease the frequency as a lot as attainable with a purpose to save energy (GDDR6X does use numerous energy) and considerably scale back the warmth in any other case generated by the reminiscence chips when mining crypto cash utilizing memory-based algorithms. The identical precept applies to different GPUs with GDDR6X video reminiscence as nicely the place extra energy financial savings could be achieved as in comparison with GDDR6 or older technology of video reminiscence.

What does appear to work fairly nicely for our check MSI Suprim X RTX 3900 playing cards by way of efficiency optimized settings is a GPU clock fastened at 1800 MHz and video reminiscence clock fastened at 807 MHz (the bottom setting we are able to get) set by means of the lolMiner command line (cclk and mclk parameters respectively). With these settings we’re getting round 1060 MH/s hashrate from a single GPU with an influence utilization of about 200W per GPU, barely various even when utilizing a number of of the identical mannequin video playing cards:

You may play with the core clock establishing or down a bit to optimize leads to your specific case, however growing the clock up from this level brings a bit of further efficiency with vital improve in energy utilization, so happening can truly be extra useful for considerably decreasing the used energy with out that a lot of a efficiency drop. In case you set the GPU at 1410 MHz and the video reminiscence once more on the lowest attainable setting of 807 MHz you may be getting a way more energy environment friendly mining with the RTX 3090s with a hashrate of 830 MH/s and energy utilization of nearly 130 Watts:

lolMiner –algo KASPA –pool stratum+tcp:// –port 3112 –consumer YOUR_KAS_WALLET –watchdog exit –cclk 1410 –mclk 807

Comparable outcomes will also be noticed on Nvidia GeForce RTX 3080 GPUs the place you may get considerably decrease energy utilization if decreasing the GDDR6X working frequency of the video reminiscence to the bottom attainable setting, 810 MHz on this case. Right here getting round 880 MH/s is feasible with a GPU clock set at 1800 MHz and an influence utilization of about 190 Watts:

lolMiner –algo KASPA –pool stratum+tcp:// –port 3112 –consumer YOUR_KAS_WALLET –watchdog exit –cclk 1800 –mclk 810

Going for 1425 MHz for the GPU and once more 810 MHz for the video reminiscence leads to 695 MH/s hashrate at about 110 Watts of energy utilization per RTX 3080 GPU:

lolMiner –algo KASPA –pool stratum+tcp:// –port 3112 –consumer YOUR_KAS_WALLET –watchdog exit –cclk 1425 –mclk 810

The strategy for RTX 3070 Ti is a bit totally different, right here we are able to energy down the video reminiscence to 810 MHz once more and the GPU at 1710 MHz to get round 590 MH/s hashrate at simply 120 Watts. The identical settings additionally apply to the RTX 3070 non-Ti fashions the place the goal of 120W of energy utilization leads to about 560 MH/s hashrate:

lolMiner –algo KASPA –pool stratum+tcp:// –port 3112 –consumer YOUR_KAS_WALLET –watchdog exit –cclk 1710 –mclk 810

Transferring on to the Nvidia GeForce GTX 1080 Ti, older, however nonetheless a well-liked mining GPU that may handle to carry out fairly nicely mining Kaspa (KAS) with low energy utilization. You may get round 470 MH/s hashrate for KAS with nearly 120 Watts of energy utilization with a GPU clock of 1550 MHz and reminiscence clocked at 810 MHz:

lolMiner –algo KASPA –pool stratum+tcp:// –port 3112 –consumer YOUR_KAS_WALLET –watchdog exit –cclk 1550 –mclk 810
