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.

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.
