Radiant (RXD) is Currently the Most Profitable Coin to Mine on GPUs

7, Dec 2022

According to the GPU profitability ranking on the What to Mine website the Radiant (RXD) crypto is currently the most profitable coin to mine on most GPUs thanks to the recent spike in popularity and price. It is the top coin in profitability for almost all Nvidia GPUs and some AMD ones with Kaspa (KAS) also finding its spot in number two and three in terms of profitability on some and Alephium (ALPH) as well as some other coins jumping in from GPU to GPU. Do note however that depending on your custom settings you might be able to achieve even better profitability thanks to increased performance or decreased power usage or both. We have some guides you can check out for optimizing performance and power usage for both RXD and KAS that might be of help here, regardless if you are mining and holding or selling the mined coins immediately.

– Optimizing Kaspa (KAS) mining for best performance with lolMiner 1.64…
– Optimizing Radiant (RXD) mining for best performance with Bzminer v12.1.1…

Both KAS and RXD are using different GPU-intensive mining algorithms for their Proof of Work (kHeavyHash and SHA512256d), so they key optimizations you can do for achieving lower power usage with maximum performance include lowering the memory to the minimum frequency supported, increasing the GPU clock together with a core clock offset to lower the voltage and the result is quite big improvement in terms of power efficiency while maintaining very high performance. Give it a try if you still haven’t and are already mining Kaspa or Radiant or are planning to do so switching form Ethash/ETChash mining for instance.

New lolMiner 1.64 For Further Optimized Kaspa (KAS) Mining Performance

5, Dec 2022

The just updated lolMiner 1.64 is a dream come true (more performance with less power used) for everyone that is currently mining Kaspa (KAS) with their Nvidia GPUs, not only because of the further improved performance that the update brings but also because of the new features it gives access to the miner for optimizing their GPUs. We did a quick test and the results are great and you should head on to your mining rigs and update and start tweaking the miners some more for additional hashrate and even lower power usage, so a win-win situation for sure.

According to the author of the miner the new version brings about 8-8.5% on Nvidia Pascal GPUs, 4.5-5% on Nvidia Turing and Ampere GPUs and 3-4% on AMD Navi and Big Navi GPUs in terms of improved performance. And thanks to the addition of the extra tweaking features and most notably the Core Offset (--coff parameter) we can not only get a boost in the performance with the same settings we were mining with version 1.63, but also get it with reduced power by just adding the extra option with a value between 250 and 350 (depending on how much your GPUs can handle stable). The --no-oc-reset might also be helpful if you do not wish to reset the settings you have applied to the GPUs when the miner is stopped.

The new beta options may require a video driver update, depending on how old Nvidia video driver you are using. The description says you need version 520 or higher, though we have them working successfully on older 512 driver, but you should probably just update if using older drivers anyway. The other new command line options added for the miner might also help to further optimize things a bit more, though they will require additional tweaking.

lolMiner 1.64 Latest Changelog:

Changes
– Improved Kaspa only mining performance. Speed increase is about 8-8.5% on Nvidia Pascal GPUs, 4.5-5% on Nvidia Turing and Ampere GPUs and 3-4% on AMD Navi and Big Navi GPUs
– Beta feature: added options to set core clock offset (--coff), memory clock offset (--moff), power limit (--pl) and a fixed fan speed (--fan) on common Nvidia GPUs. Required are admin privileges and Nvidia drivers 520 or higher!
– The syntax is the same as with --cclk and --mclk – if a single value is given then it will be applied to all compatible GPUs, else a coma separated list of values can be given using a * character to skip over GPUs. (1)
– Added a new parameter --no-oc-reset to turn off the reset of overclock settings when ending the miner.
– Windows: Added a beta gui to generate overclock settings strings / .bat files for the miner. Also the tool can apply the chosen settings directly.

(1) Note: No responsibility taken for the values set. Please use with care. If your mining os had build in functions to set these settings we recommend using them instead of the miner settings.

Fixes
– Fixing a bug with ETHV1 (nicehash) stratum mode that may cause the worker name to be appended twice when it was given by –user . (the use of –worker did not have this issue).

Here is a quick overview of what improvements we are getting with the new version on RTX 3070, 3080 and 3090:

GeForce RTX 3070:
lolminer 1.63: 564 MH/s – 120W – 1710/810
lolminer 1.64: 596 MH/s – 95W plus the extra option --coff 300

GeForce RTX 3080:
lolminer 1.63: 877 MH/s – 190W – 1800/810
lolminer 1.64: 919 MH/s – 160W plus the extra option --coff 250

GeForce RTX 3090:
lolminer 1.63: 1031 MH/s – 200W – 1800/807
lolminer 1.64: 1079 MH/s – 160W plus the extra option --coff 350

Here is an example you can use for RTX 3070, just replace YOUR_KAS_WALLET with your actual wallet:

lolMiner --algo KASPA --pool stratum+tcp://pool.eu.woolypooly.com --port 3112 --user YOUR_KAS_WALLET --watchdog exit --cclk 1710 --mclk 810 --coff 300

You can try to play around with the core offset setting, though 250 to 350 MHz should be safe for most GPUs, some may require lower setting to function stable or can take up higher offset for even greater power savings. As for the memory clocks and settings with example command lines, you can take a look at the post where we talk about Optimizing Nvidia GPUs for Performance with Lower Power Usage for Kaspa (KAS) Mining. Just use these examples for the specific GPUs discussed there and add the Clock Offset parameter to them as a good starting point and see how your power usage drops while you get extra hashrate after the update.

New lolMiner 1.63 With Improved Kaspa (KAS) Mining Performance

23, Nov 2022

There is a new lolMiner 1.63 release available for anyone using that mining software, and it is an especially useful update for anyone out there that might be currently mining Kaspa (KAS)… and if you are not yet mining KAS, then you might want to consider starting to mine Kaspa it with your GPUs. The project has great underlying technology with more in the works and has already started generating buzz around crypto miners and traders, not to mention that it has the potential to become the next big Layer 1 crypto that can actually be mined with GPUs and that is something we kind of need lately… getting back to the roots of crypto. Anyway, our advice is to check Kaspa (KAS) out now if you still haven’t done so, or you might be sorry later on that you missed the early opportunity. If you are not too sure yet, you might try also Triple Mining ETC + KAS + ZIL or any other Ethash/ETChash crypto with Zilliqa and Kaspa on the side. This way you will be mining less KAS, but it will be just extra without losing any of the mining hashrate for the other coins, or with just a very slight drop (dependent on your power limiter settings as well).

Back to the mining part and the mining software, the latest lolMiner 1.63 there is a slight improvement in performance and energy efficiency that can help you get even more performance out of your Nvidia mining GPUs that are already mining KAS. Increasing the power limiter with just a few percent over the settings you use optimally for ETH/ETC mining could also help in getting some extra hashrate as well, either for single mining KAS or for Triple mining it. There are also some fixes that might should make the miner running better and giving you less problems as well. The upgrade to the latest version 1.63 is a must for anyone mining Kaspa (KAS) and recommended for people mining other crypto cons with it. Below you can read the full changelog of the latest release of lolMiner.

lolMiner 1.63 Changelog
Changes
– Improved the Kaspa only mining performance on Nvidia Turing, Ampere and Ada GPUs by about 3.5%. (1)
– Significantly improved the Kaspa only mining energy efficiency on Nvidia Turing, Ampere and Ada GPUs by 7-11% depending on the actual model.
– Values given to --dualfactor parameter will now be value checked and rounded / capped to working values.

(1) Can be higher in case the card was power limited before.

Fixes
– Fixed a bug causing the miner to show a crash message when lolMiner was ended via ctrl+c
– Fixed a bug causing lolMiner not to start Kaspa mining on Nvidia GPUs when the Nvidia OpenCL installation on the system is broken.
