The controversy surrounding the release of a number of CryptoNight ASIC miners from various manufacturers and the upcoming fork of Monero (XMR) and some other crypto coins to a new ASIC-proof CryptoNightV7 algorithm continues. NiceHash has recently announced that they will continue to support both the old CryptoNight as well as the new CryptoNightV7 algorithms. The service should add support for the new V7 algorithm by the end of the month, probably before the Monero fork planned to happen later this month. Furthermore a new NiceHash Miner that will bring support for the CryptoNightV7 algorithm should also be available soon, so while the updated POW algorithm will be ASIC-proof you would still be able to rent a lot of GPU hashpower apparently.

Other crypto coins that are using the same cryptoNight proof of work mining algorithm are expected to follow suit and also fork to the new ASIC-proof version of CryptoNight, though it would most likely take them some extra time. There are some coins that have already announced their plans to do a hard fork and follow in the footsteps of Monero (XMR), others are still considering and of course there will be some for sure that will remain on the old algorithm that can be mined using the upcoming wave of CryptoNight ASIc miners. Still going for a CryptoNight ASIC miner at the moment is considered very risky and will most likely cost you much more that you would be able to mine back, though there are no guarantees.

To keep track of the time left until Monero (XMR) hard forks to the new CryptoNightV7…

InterPlanetery Broadcast Coin (IPBC) is a new project for sharing digital content online with with an integrated cryptocurrency ecosystem. Think along the lines of YouTube, but without any advertisements, instead users uploading videos on the platform get compensated by the people watching them. IPBC comes with a web media miner that essentially uses some of your computer’s resources to mine while you watch the video and all the used hashpower gets credited to the person that has uploaded the video. There is no need for visitors to download and use a dedicated miner, everything happens directly inside the browser and the mining does not interfere with the video watching.

The best thing is that even though IPBC is still a new project the video platform with mining integration is already available, so it is not just something promised to come out after months as it is already out there. You can of course also mine IPBC coins the traditional way, the project uses Cryptonote/Cryptonight (just like Monero) and there are already quite a few pools out there (aside from the official ones) that offer you to mine it. Of course if you are a video content producer you might want to also try the IPBC platform and upload some videos and try that as well. There is also a web-based miner available for users built inside the platform, though you probably would want to stick to GPU mining with dedicated mining rigs than to use the web-based CPU miner yourself.

The project looks promising and is already doing quite well even though it is just a few days since the official announcement, the team has already announced their plans to have the coin listed on an exchange (listing on Livecoin has been announced for February 21st) as well as other interesting plans for improvements and new features… remember that it has just launched and the IPBC platform is still in beta.

For a while now the CryptoNight algorithm used by crypto coins such as Electroneum (ETN), Monero (XMR), Sumokoin (SUMO), Karbowanec (KRB) and maybe some others have been quite profitable to be mined by AMD GPUs. That is normal since AMD GPUs are doing better than Nvidia when talking about the CryptoNight algorithm, especially the latest AMD Radeon RX Vega GPUs that are doing really great in that algorithm. Even though AMD’s latest GPUs are still not entirely problem free in terms of software support and can give you some headaches making them work for mining, when they do they work really well for CryptoNight performance wise. We have prepared a quick and easy to follow guide to help you get started and save you some trouble mining CryptoNight with Vega GPUs.

– Start by downloading and installing the Radeon Software Crimson ReLive Edition Beta for Blockchain Compute as this is the driver that probably still offers the best performance for mining CryptoNight on VEGA.

– When you install the driver you need to go through the Radeon Settings / Gaming / Global Settings and for each and every GPU in your mining rig to make sure that HBCC Memory Segment is disabled as well as if you have Crossfire enabled for a pair of GPUs to also disable it. Reboot the system and check that all of the video cards have HBCC and Crossfire disabled before continuing further.

– Each time the system starts you need to disable and re-enable all of the GPUs in your system in order to get the best mining performance, you can do it manually via the Device Manager, though there is also an automated way to do it, so that the mining can start automatically on each boot. For that you need to download the respective version of Devcon for the Windows you are using, here is an easy way to obtain the required devcon version.

– Here is how to disable all AMD RX Vega GPUs and then re-enable them with the DevCon.exe tool:
devcon.exe disable "PCI\VEN_1002&DEV_687F"
devcon.exe enable "PCI\VEN_1002&DEV_687F"

– The next step is to overclock/underclock the GPUs so that you can get the optimal performance and power usage combination, here things may vary in terms of the settings you can use from card to card. You can use AMD’s Radeon Wattman built-in tool, but it is not very convenient, so going for OverdriveNTool might make things much easier in the process of testing GPU and Memory clock settings.

– Some people set the final GPU frequency/voltage settings in the registry after they finish with the test what works best, so that they are loaded automatically on boot. We however prefer to use the profile feature of the OverdriveNTool and load and apply the settings from a profile before starting the miner. Here is an example how you can load a profile you save as “XMR” for 6 GPUs using the OverdriveNTool, this way you can easily have different profiles for different algorithms:
OverdriveNTool.exe -p0"XMR" -p1"XMR" -p2"XMR" -p3"XMR" -p4"XMR" -p5"XMR"

– Now you can go for the CryptoNight miner software, there are number of these, but not all of them give you the best performance on Radeon RX Vega GPUs. The two choices for best performance at the moment are Cast XMR and the latest version of XMR-stak. If using XMR-stak just make sure you configure the miner with two threads per GPU, this would require more virtual memory. Both miners need quite a lot of virtual memory, so make sure you have something like 48-64 GB to be on the safe side and problem free.

Following the tips above you should be able to get 1800-2000 H/s for mining CryptoNight on a single AMD Radeon RX Vega GPU, depending on your GPU and memory settings, so the performance is quite good if you are able to keep the video cards cool enough. If using the XMR-stak miner you can also mine some coins using the CryptoNight-light such as AEON, the settings are the same, this algorithm just produces about double the normal CryptoNight hashrate.
