RVN mining reconnecting issue, please help!

So, I've been mining RVN for a few days on Ravenminer pool using TeamRedMiner.

On my RX 570 I was getting a peak of 11.5 MH/s with a BIOS flash and I noticed if I reduced the memory clock and undervolted the GPU I would get 12.5 MH/s.

I can't see how that is possible but it's true.

However, when I lose connection and then regain it, my miner reconnects automatically but with reduced hashrate down to only 8 MH/s. So I will have to close the miner and go to AMD Radeon Software and reset the clocks and then restart the miner and lower back the settings in order for it to work.

what would be the cause of that? any fix?

Thank you in advance!
