New lolMiner 1.67 Release Focused on Improving NEXA Mining Performance

6, Feb 2023

There is a new lolMiner 1.67 release that is apparently focused on improving support and performance for the nexapow algorithm used by the NEXA project. The performance improvements can vary depending on the kind of Nvidia GPUs you have available and can go as high as up to about 35% as per the developer, though it can also be just a couple of percent as well. It seems that locking the video memory to 5000 MHz does allow for improved performance as opposed to leaving it at it higher stock frequency or lowering it too much (NEXA does like faster clock for the memory in terms of performance).

You might want to try and compare how will your mining hashrate be affected with the --mclk 5000 option to lock the video memory at 5000 MHz, also do not forget to set the GPU clock higher as NEXA is using a more GPU-intensive algorithm. The way to lower power usage here is by utilizing the core clock offset in order to lower the GPU operating voltage and thus go lower than the power limit you have probably set already, that is the --coff command line parameter you can experiment with 200-300 as a value and see what works well on your GPUs if it is not stable at 200, then you might try to lower the GPU clock frequency a bit.

lolMiner 1.67 Latest Changelog:
Changes
– Improved Nexa performance on Nvidia Turing based gpus by approximately 35%+.
– Improved Nexa performance on 8G Nvidia Ampere gpus by approximately 1.5% when memory is not locked and ~3% on locked memory (5000). 10G and higher gpus got an additional 5% performance increase.
– Improved Nexa performance on Nvidia Ada based gpus by approximately 25% on locked memory clock (5000) and about 8% on unlocked memory.
– Added Nexa echelon mining protocol to support pools using it, e.g. 137pool.org. The needed format will be automatically detected when connecting to a pool using it.
– Updated WebUI for Nexa mining and more pools to support.
– Windows: Updated GUI

Fixes
– Fixed a bug causing scattered defect shared on Nexa mining (all OS)
– Fixed a display bug when setting power limit on Nvidia GPUs saying the value is out of Range, although its fine. (all OS)
– Fixed a bug in Nexa mining of the miner creating only defects (Windows)
– Fixed a bug in Nexa mining of the miner crashing silently after a few minutes (Windows)

Note 1: Every code update – in particular when so massive as here – may require re-tuning your oc & uv settings for ideal results and stability.
Note 2: memory locking on Ada gpus is only recommended if the core clock is locked as well and not maxed out – on high core clock in combination with memory locked to 5000 the performance will struggle due to worse memory timings.

General note: The Nexa gpu codes are (and will be in foreseeable future) joint work with Iedoc from BzMiner. Miner fees will be evenly shared regardless of which of these two flavors of the code you prefer.

The Latest lolMiner 1.66 Adds support for NEXA Mining as Well

26, Jan 2023

The just updated lolMiner 1.66 has also introduced support for the nexapow algorithm used by the NEXA project, something we kind of expected after the recent release of BzMiner v13.0.1 that included a mention of that NEXA support has been jointly developed with the developer of lolMiner. And now the release of lolMiner 1.66 brings that along with a mention of an upcoming BzMiner update to bring better performance of about 20% and lower development fee of 2%, the same as what we are expecting to see from this release in lolMiner.

Prior to this release of lolMiner the fastest NEXA miner out there was the newcomer Rigel Nvidia GPU miner, so the big question is if the lolMiner is managing to surpass its performance and get the new top spot? Well, the answer is that it did manage to outperform slightly even the just updated Rigel miner 1.3.1 that also brought some 3-5% extra since the initial 1.3.0 release. So, the new lolMiner 1.66 is now the to go NEXA miner for Nvidia GPUs fi you are looking to get the optimal mining performance at the moment. The hashrate that the new lolMiner offers for NEXA mining is a bit faster than what the Rigel miner currently does and it is with the same developer fee of 2% for both and the next update of BzMiner should also do similar level of performance when it is updated. The performance boost for lolMiner is around 5% on commonly used Nvidia GPUs like the RTX 3070, though some like the RTX 3070 Ti, RTX 3080 and RTX 3090 might show the about same level of performance as with the latest version 1.3.1 of the Rigel miner!

lolMiner 1.66 Latest Changelog:
– Added support for mining Nexa on Nvidia Pascal or newer generation GPUs (1). Use --algo NEXA to mine it. Fee is 2%.
— Note: The pool protocol supported matches the one introduced by rplant pool. That said pools tested by this version are in alphabetical order: acc-pool.pw, rplant.xyz, vipor.net and woolypooly.com. That said this list is not exclusive and every other pool following this protocol should work.
— Note 2: This code is joint work with Iedoc from BzMiner and it is a refined version with approximately 20% higher speed then the code released in BzMiner v13.0.1. An updated version of BzMiner featuring the improvements of this kernel as well as the same fee level will be released soon.

— (1) Primary focus in optimization were the low to medium range Nvidia Ampere GPUs. The performance of other generations may vary, but certainly improve the next versions.

Do note that lolMiner’s support for NEXA mining is only for Nvidia GPUs and it covers Nvidia Pascal or newer generations, it should work with all of the major NEXA mining pools, so you are more than welcome to spread the hashrate if you are mining NEXA and not go straight to the largest pool as many people normally do. AMD GPU miners do seem to be kind of left out for the moment unfortunately as far as NEXA mining is concerned and the focus seems to be on Nvidia GPU miners for the moment.

Low Power Optimized Mining of Dynex (DNX) on Windows

15, Jan 2023

There are a lot of GPU-intensive crypto coins out there that can be mined with video cards that unlike ETH/ETC and other memory-intensive algorithms do not require a lot of gigabytes of video memory or a very fast memory access speeds or clocks. One interesting such projects is Dynex (DNX) and we’ve already covered it last month as something interesting that might deserve your attention and mining power (still Nvidia GPU mining only). Now, we are going to be focusing on a different aspect of mining DNX that uses its own custom miner that unlike most other multi-mining software does not support GPU tweaking options. This means that if you do not optimize the GPUs you are using for mining you will be wasting a lot of extra power without any gain in performance and at times of lower profitability for mining this is not something you should be eager to do.

Miners that use Linux-based operating systems such as HiveOS have more options to control the operating parameters of their GPU-based mining rigs regardless of what miner software they currently employ, however Windows users are having a hard time doing the same thing. There are some useful graphical tools such as MSI AfterBurner or command-line tools such as nvidia-smi, but they are not as useful or easy to use or functional as one might think. The good news here is that Windows users might use some “cheats” in easily tweaking their mining hardware the way they want it to, regardless of the miner software they utilize.

This is possible all thanks to some of the new features introduced lately in the lolMiner mining software. These are not only the options for command line setting the GPU core clock, memory clock, power limit and the core clock offset, but also and very importantly the option to turn off the reset of overclock settings when exiting the miner. This means that you can run the lolMiner software briefly (make sure it is ran as Administrator for clock settings to work), quit it and have it leave the settings you applied for the GPU clock and then just run another miner like DynexSolve for mining DNX or just about another one. Just make sure that the mining software you run after that does not manage GPU settings on its own or does reset them to some default states as it will defeat the whole purpose.

Below you can find an example command line to run lolMiner setting the clocks on RTX 3070 GPU and then automatically exiting without resetting them back to the standard ones when exiting. Since we run lolMiner without a real KAS address it connects to the pool and then automatically exits the miner and then we run the DynexSolve miner and start mining DNX with the same optimized GPU setting that we would’ve used for mining Kaspa for instance with lolMiner. This way we get the same or maybe even higher performance with lowered power usage than if we just run the DynexSolver miner with the default settings for the GPU, just don’t forget to add your DNX wallet in the example below (do not add KAS wallet, leave the x there):

lolMiner.exe --algo KASPA --pool stratum+tcp://pool.eu.woolypooly.com --port 3112 --user x --watchdog exit --cclk 1710 --mclk 810 --coff 300 --no-oc-reset

dynexsolvevs.exe -mining-address YOUR_WALLET -no-cpu -multi-gpu -stratum-url dynex.neuropool.net -stratum-port 19331 -stratum-password YOUR_WORKER_ID -stratum-paymentid YOUR_PAYMENT_ID

The same thing can be applied to another miner and another crypto coin that is GPU-intensive and you can lower the video memory to the minimum and also decrease the operating frequency of the GPU to a lower level that it can still handle mining at with a high-enough operating frequency. This way you can go significantly lower than 100 Watts per RTX 3070 GPU and still managing to maintain the pretty much same hashrate that you would normally achieve mining at stock settings. And if the coins tolerate even higher GPU clock and that brings extra performance you can utilize the extra power usage headroom for further increasing the performance you get while maintaining much lower power usage in general.
