VDN (vDinar) is a relatively new regional-oriented crypto currency that has been getting more attention lately. It was CPU-mineable up until recently, though it seems that there is a ccMiner fork available (source) supporting the vCrypt algorithm that the coin uses for mining. The vCrypt algorithm is not entirely new mining algorithm, it is more like a variation of the Scrypt-N algorithm, though you are not able to mine vDinar with regular Scrypt-N miners.

Unfortunately there seems to be no binary version of the ccMiner for for Vcrypt, because it seems that the GitHub source of the Veles miner fork of ccMiner is incomplete and many people are having trouble compiling it by themselves. That is why we have compiled a 32-bit Windows binary of the miner with VC2013 and CUDA 8.0, it supports Compute 3.0, 5.0 and 5.2 and should work with pretty much any more recent Nvidia GPU. Do note however that the vCrypt algorithm is pretty heavy on the CPU, so you may have trouble achieving maximum hashrate if you have a slower dual-core CPU like the commonly used Intel Celeron processors for GPU mining rigs.

Performance wise you can expect something like 900-950 KHS from a GTX 1080 Ti, 700-ish from GTX 1070 Ti, 450-500 from GTX 1060, but that is only if you have a high-end CPU. With a slower processor such as Intel Celeron G3930 for example you might be getting just a fraction of the actual hashrate, because of the slow processor performance and the miner maxing out the CPU usage. You can try running multiple instances of the miner for better results and also feel free to play around and experiment with different launch settings to see if this might improve the situation with performance and share your findings, but again, have in mind that to get good performance with vCrypt on a multi-GPU mining rig you will need a really high-end CPU.

The latest update to the Bminer Equihash Nvidia miner brings a number of useful improvements for users that are mining ZCash (ZEC) or other Equihash-based crypto coins on Nvidia GPUs. The newest version 6.0.0 of the miner brings slight performance improvement in the hashrate, faster startup time and reduced CPU usage, comes with a failover server support, provides reduced reject rate caused by stale shares and a simple GUI launcher for Windows to make it even easier for novice users to set thing up. There are of course a number of other smaller improvements and fixes also available in this update to help you get better results and give you more flexibility.

For those of you that have not yet tried this Equihash miner, do note that it also has a simple web-based status interface that shows useful information like uptime, speed, power consumption and efficiency as well as some graphs for temperature and hashrate variation. So all in all a very nice list of improvements in the latest version of Bminer that makes it an even better alternative to more popular and widely used alternatives such as EWBF’s miner or dstm’s ZCash CUDA Miner. If you have not tried this miner the last time we talked about it when it was still new and getting up to speed, now might be a good time to give it a go.

The Cast XMR CryptoNight GPU miner for AMD RX VEGA 56/64 GPUs has just been updated to version 0.9.1 with a slight performance improvement of 0.5% overall for Vega-based GPUs according to the developer of the software. The previous version 0.9.0 from eralier this month has already added support for the upcoming CryptoNightv7 fork for Monero (XMR) and other coins in the view of the new wave of ASIC miners targeting that crypto algorithm. Do note that Cast XMR is a closed source miner available as a binary only for 64-bit Windows and comes with a 1.5% developer fee. It is originally optimized for ADM RX VEGA GPUs using the Blockchain driver, though it should also work fine on other AMD RX series of GPUs.

Cast XMR should be able to autodetect and switch between CryptoNight and CryptoNightV7 on Monero (XMR) and most other coisn that decide to fork as well, though there is also an option available to switch manually to the desired version of the CryptoNiht algorithm in case there is an issue with the autodetection (use the --algo command line option). Currently it seems that the only GRAFT is having trouble working properly with the autodetection mechanism, so it is advised to manually select the version for the moment. GRAFT has not yet forked, so it is currently still using the old CryptoNight version and not the new V7 as are pretty much all other coins that have already announced their plans to also fork to v7. Just as a reminder, Monero (XMR) will fork at block 1546000 or around April 4th and that is less than two weeks away.
