Hello everybody, is this thread active?

I'm having some troubles I believe, I've started using RaveOS this week and it's awesome. It recognized my cards and I started mining using lolminer 1.20...

The thing is that I have 12 almost obsolete cards for mining, AMD RX570 4GB... They're on two separated rigs, they work just fine, but the hashrate is very, very low... They get to work at 13Mh/s each, tops, and I'm not sure if that's all they can handle now because of the DAG size or is it something with the miner and I should try another one... What do you think?

Thanks in advance.
