The latest releases of Bminer 14.1.0 and NBMiner 14.0 have announced pretty impressive performance increases regarding Bytom (BTM) mining hashrate on the new Nvidia RTX series of GPUs with up to about 200% boost, so a significant improvement indeed. This essentially makes the RTX series of GPUs the best choice for BTM mining with two to tree times faster hashrates compared to what their older GTX counterparts are able to deliver at the moment.

Another new improvement that goes for both miners is the additional performance improvement in the range of about 30% for GRIN mining with hashrates very close for the two miners. Bminer also brings similar performance improvement for Aethernity like for Grin. So make sure you do try them both to see what may work better on your specific GPUs and settings if you are currently mining GRIN. Our tests are showing that the latest GMiner 1.25 still seems slightly faster on GTX 1080 Ti GPUs compared to what we are getting on the same hardware with the latest BMiner and NBMiner, so make sure you check out the latest Gminer as well.

NiceHash hasn’t added new algorithms for a while now with ZHash being the last new addition in early December last year, so it is interesting that they have added support for BEAM now. This is both good and bad news for some people as the profit for selling your BEAM (Equihash 150,5) hashrate on NiceHash might bring you nice direct profit in BTC, but for the people mining BEAM directly is is not such good news as the hashrate has increased significantly and thus the difficulty is higher as well and less coins are being mined. Pool owners with BEAM support might be interested in checking out the BEAM NiceHash support specs in order to make sure that their pools will be compatible with hashrate coming from the service.

We have already tried some of the popular mining software with NiceHash and it seems that there are no problems connecting and using Bminer and Gminer on Nvidia GPUs does seem to work without problems (remove the SSL option from both miners), however the latest lolMiner for AMD does not seem to support NiceHash mining at the moment in its latest version. The algorithm that BEAM uses is Equihash 150/5, so other miners supporting that algorithm should in theory be compatible with NiceHash as well, though there is no guarantee for that.

The Braiins OS is an alternative opensource OS for Bitcoin ASIC miners and more specifically for Antminer S9 and DragonMint T1 with support for AsicBoost. The initial release was not that easy to install and use, but looked very promising, but in December last year the second major version named Braiins OS Cobalt was made available and it made things much easier for everyone to switch from the factory firmware. The initial Cobalt release however was missing a crucial feature as we have noted and that was manual fan control as by default the automatic control was keeping high operating temperatures and fans spinning at lower RPM. This has been fixed in the new second release along with some more useful features and improvements worth upgrading to the new release or switching from the stock firmware. If you want to read the full list of what is new in the latest Braiins OS Cobalt release.

In the latest version you have the option to use either Automatic Fan Control or set Fixed Fan Speed. In automatic mode you can set the desired temperature and the fan controller will try to keep as close as possible to that temperature by varying the fan speed. The fixed speed mode is set in percentage and the fans will operate at the set value regardless of the temperature, so you need to be careful with this mode, though setting at 100% target fan speed should be pretty safe. Do note that the operating temperature depends not only on the cooling fans of the miner, but also on the ambient air temperatures and other factors.

Another new interesting feature is the new frequency scaling mode that is essentially an overclocking multiplier allowing you to set an overclock by a constant factor for all of the miner chains at once over the overclock settings you may have individually set already. Overclocking is easier in the new release as you are able to lower the temperatures by manually controlling the fan speeds now thus getting more headroom for overclocking. When overclocking also make sure that not only the cooling can handle things, but also the power supply you are using is sufficient enough as well, especially if you start increasing the operating voltages as well and not only the frequencies.

There is now a new sgminer fork with MTP support being actively developed by djm34 (source) that looks promising, though it might need some more extra work for becoming more stable stable and reliable. Performance results on AMD RX 580 and AMD VEGA GPUs are quite good compared to what Nvidia MTP miners are currently offering and hashrate is much better than what the only available option with MTP support for ADM so far was delivering up until now – WildRig Multi. So if you are interested in mining ZCoin using the MTP algorithm on AMD you might want to give the new sgminer fork a try, there are two separate kernels available – mtp and mtp_vega and you might try both on your AMD GPUs to see what works better. Do note that the sgminer fork with MTP support is currently only available with a Windows binаry, though since it is open source you can try compiling it on Linux.

When we are talking about Cryptonote (Cryptonight) miners for AMD GPUs our preferred miner is SRBMiner due to the large range of supported variations and features, however there is a good competitor available and that one is called JCE Cryptonote CPU+GPU miner. The JCE miner is a closed source software available as a binary for Windows only (for the GPU) and with 0.9% developer fee for the GPUs (the separate CPU miner is with higher fees, Linux version is available for this one). In terms of performance the JCE miner is pretty much on par with the fastest alternatives like SRB, sometimes it might be a bit faster, sometimes a bit slower, depending on the algorithm and settings. For instance our latest experience shows a bit better performance for Tube mining using JCE compared to the latest SRB 1.7.7 on RX 580. The JCE miner does support a lot of the Cryptonothe (Cryptonight) variations out there, so you can use it to mine pretty much all popular variants. There is support for SSL as well as for NiceHash’s extranonce functionality

There are already a number of miners available for Nvidia GPUs that support the Equihash 150,5 algorithm used by BEAM, however there aren’t that much available to AMD miners and there is pretty much just one being actively developed at the moment – lolMiner. The lolMiner is a closed source Equihash GPU miner available for Windows and Linux and focused on AMD GPU, though it also works with Nvidia GPUs, in order to get support for BEAM’s Equihash 150,5 algorithm you need to go for the newer 0.7 alpha version with alpha4 being the latest. The latest version of the miner should work with 3GB VRAM GPUs, though there could be some issues if using Windows 10 on your mining rigs.

The performance you can expect on AMD’s RX 580 GPUs is about 11-12 Sol/s, pretty much the same that Nvidia GTX 1060 can deliver on Equihash 150,5. If you have older AMD HD 7970 or R9 280 you can get slightly less at about 10 Sol/s and on AMD VEGA you should be able to get up to about twice that hashrate, so performance is quite good on AMD. The fastest miners for Nvidia GPUs however are doing better than AMD GPUs, like about 30 Sol/s on GTX 1080 Ti for example, so have that in mind as well.

The latest Bminer 13.0.0 should be the preferred choice for a Nvidia GPU miners that are currently mining Grin as it offers the best performance at the moment compared to other available miners. However there are still some things that may need extra work such as full worker support for Sparkpool (one of the first and largest currently available for Grin mining). At the moment you can use Bminer with Sparkpool, but all your rigs will be under a single worker called “miner-rig-0” as the worker setting of the pool interfere with the settings for pool, username and password schema that Bminer uses. The extra performance of up to about 50-60% compared to other miners such as NBminer or GMiner and others is well worth it.

We remind you that that Bminer is a closed source Nvidia GPU miner available for Linux and Windows in the form of pre-compiled binaries and that there is a 2% development fee for Grin, Beam, Bytom (BTM), Equihash and Zhash coins, 0.65% for Ethash and 1.3% for dual mining Ethash and Blake.

GMiner has just added support for the new Cuckaroo29 algorithm being used by Grin with the latest update to version 1.19. This marks the first non-Equihash algorithm getting support in the miner and maybe it will also open the doors for other algorithms to get implemented in the future. Performance wise it may not be the fastest Grin miner out there, but it does seem to work quite well based on our short experience with the new version for now, so you might want to give it a try. Due t the higher video memory requirements of the Cuckaroo29 algorithm you will need to have an Nvidia GPU with 8GB VRAM (about 7GB are currently required) as well as enough virtual memory available.

Apart from Cuckaroo29 GMiner also supports Equihash 96,5, Equihash 144,5, Equihash 150,5, Equihash 192,7 and Equihash 210,9. The miner requires an Nvidia GPU with CUDA compute capability 5.0 or later as well as CUDA 9.0 driver support. Do note that GMiner is a closed source miner for Nvidia GPUs with binaries available for both Windows and Linux, also there is a 2% developer fee built-in the software.

Grin is a new crypto project for creating a the private and lightweight mimblewimble blockchain that would provide electronic transactions for everyone without censorship or restrictions. The algorithm that Grin uses is Cuckoo Cycle with 1 minute block time, 60 GRIN block reward and no limit on coin supply or reward halving. There is not going to be any ICO, founders reward, pre-mine or masternodes available for this project, so people that do not like any of these should be Ok with this project. Miners for Grin are still currently being developed, although there are some already announced or available, though initially it could be a bit of a challenge to make things work with the right miner and pool. For instance the official MWGrinPool is currently not taking new registrations, though new pools should be available as alternatives. There are already a couple of options for pools on the Testnet where you can test the mining before the Mainnet launch like Spark Pool.

The official open-source Grin Miner software is currently only available for Linux and Mac OS X and it supports both CUDA and OpenCL mining. For miners looking for Windows miners there is the Grin Gold Miner (with 1% fee for the Grin Development Fund and 1% fee for further miner development), although it also works with Linux) that supports all AMD and NVIDIA 8GB cards (requires a GPU with 8GB VRAM!). Do note however that Nvdia RTX 8GB cards need Linux or Windows 7 due to memory addressing issues. RTX 2080 and RTX 2080 Ti are fastest in terms of performance if you manage to make them work, OpenCL code for AMD cards is currently still being optimized. Cheaper slower Celeron CPUs are not recommended for many cards on the system (similar to Merit and BITC that also use the same algorithm for mining). Another alternative for Windows miners should be the GrinPro Miner that is not yet available for download and that will have 2% developer fee. This miner should work on AMD and Nvidia GPUs with 8GB VRAM, although it promises upcoming support for 6GB VRAM cards as well, so that could be interesting for some users.

Unfortunately zjazz, who was pretty active in miner development for Cuckoo Cycle support for Merit and BITC hasn’t updated his miner for a while and will probably not be supporting Grin mining at least for the moment. The latest version of Bminer that was just made available however also comes with experimental support for mining Grin, so you might want to check it out as well. Do note that it is a closed source miner with 2% developer fee, so have that in mind as well when checking out different miners for Grin.
