It Is All About BTC, LTC, ETH, DOGE, KAS mining as well as other alternative crypto currencies
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.
There are just a few days left until the fork of Monero (XMR) to CryptoNightV7 to make it again ASIC resistant and you might want to be ready for mining it after the fork, especialyl if you have ADM RX VEGA GPUs. So far the latest Claymore’s CryptoNote AMD GPU Miner does not yet have support for CryptoNightV7, but for VEGA GPUs you probably are using XMR-stak (also not ready) or Cast-XMR or the more recently announced Xrig. The last two have already been updated and their latest versions do come with support for CryptoNightV7, so you should update to Xrig 0.8.1 and Cast XMR 0.9.1 in order to be sure you are ready for the fork. Although these miners are optimized especially for VEGA mining, they should work on other AMD RX series of GPUs like 470/480 and 570/580 for example, so until a Claymore adds CryptoNightV7 support you can try using these miners as well. After Monero forks to the new CryptoNightV7 POW other coins are also expected to do the same and remain to be ASIC proof. The upcoming Monero (XMR) fork to CryptoNight v7 is scheduled for block 1546000 which should happen some time around 2018-04-06 (April 4th), so less than 2 weeks left until the fork.
It has been a while since we have last CPU mined a crypto coin that only has a CPU miner and not a GPU or ASIC and uses a new crypto algorithm, it has been a while since we have used the cpuminer-opt as well. So why not get back to it and put some stress on your processor for mining using the latest cpuminer-opt 3.8.4 (download) and mine WAVI coins (Bitcointalk announcement) that use the new yescryptr32 algorithm.
If you are interested in what kind of performance you can expect mining this algorithm with a CPU, here is a reference for you. An Intel Core i7 6850K (6-cores at 3.6 GHz + HT) does around 635 H/s in the yescryptr32 algorithm without overclock of the processor. A processor like the commonly used Intel Celeron G1840 (Dual Core at 2.8 GHz) manages to get around 110 H/s in terms of hashrate when mining yescryptr32. If you try mining WAVI coins with a different processor feel free to share your performance results in the comments below…
