Hi! First off, congrats on the work done on this miner.
I've been using cast and not happy with it and it became very unstable.
I've tried SRB using minimal config and it connected correctly. Immediately I saw better hashrate with the same configs, but it gets several jobs and sends no shares, which is really strange. So I started playing around with the settings, and now it doesn't even start

These are my files. What am I doing wrong here? Also want to put the restart script in, but haven't tried yet.
I'd really appreciate if you could help me on getting SRB cracking =)
Thanks
PS: the GPU restart seems to do it one by one, then says it restarted correctly, and shuts down after a quick message in red
...
I only had GPU crashes with too aggressive intensity or too aggressive memstraps/overclock/undervolt settings.
So, you could try setting the intensity manually lower than SRBMiner now does it based on your setting 0. This might work, but more likely it is in the profile you use with Overdriventool. I don't have VEGa's, but general advice here would be to cut back what you are doing there more to stock value and then see if it improves. Once you have a stable situation, crank it up.
Hope this works for you. May be somebody else can give you his Vega settings as a reference to try.
