It did not take long and now the latest GMiner 2.04 GPU miner had added support for the new KAWPOW mining algorithm that RavenCoin (RVN) might/could/should/would be forking to sometime in April. The KAWPOW algorithm is a derivative of ProgPOW with parameters specific for RavenCoin, so another miner with ProgPoW support will not work unless specific RVN support is added like in the case of GMiner that already had ProgPoW support, but needed an update for KAWPOW support. Do note that support for KAWPOW is currently only available for Nvidia GPUs and that goes for ProgPoW as well. You can already test KAWPOW support on the RavenCoin test network to get ready your miner, there miner RVNt testnet tokens do not have any value though.
Besides the new algorithm being added, the latest version of GMiner addresses an issue we have noted regarding high CPU usage in Qitmeer (PMEER) support. There is a new “--trim” parameter being introduced to control additional trim round count for Cuckoo24 (Qitmeer) algorithm that should help reduce CPU load, so you can give it a try and see if it helps if you have any GPU mining rigs with lower-end CPUs that have high CPU load issue.
The GMiner miner software was originally only an Nvidia GPU miner, although some algorithms are already supported on AMD GPUs as well. Do note that GMiner is a closed source miner for Nvidia and AMD GPUs with binaries available for both Windows and Linux, there is a 2% developer fee built-in the software.
