I noticed that most people are using the ccminer from enemy-1.03 for RavenCoin (Info's Source: http://yiimp.eu/site/miners). However I can't find it available as open source and I'm afraid it might be doing something fishy on the background.
People are already comenting here http://cryptomining-blog.com/9507-ccminer-enemy-1-03-fork-for-raven-rvn-mining-now-available/ about suspicious activity.
TPRUVOT's ccminer is so buggy, it's always crushing even when KlausT's version keeps going with the same clocks. However KlausT hasn't add RVN support (at least yet).

So... Is there any stable and safe miner for Raven?

PS: TPRUVOT's ccminer hashrate is jumbing between 12 MH/s and 20 MH/s on 1080ti! WTH?! I reduced my clocks to try avoid crashes and I'm at 80% TDP, +70 GPU, +500 Memory. Let's see if it last more than 2 hours.
