Hey guys. Just set up my first mining rig a few days ago. Got my RX 580 to run 30-31 MH/s with some relatively simple mods (will be adding more gpus soon!). Right now I'm having an issue with stale shares I can't quite figure out. It's reporting that 30% of my accepted shares are stale. Right now I'm mining on phoenixminer using the us1 ethermine pool. I only have like 55ms latency as well. At first I thought it might just be my overclock that is causing stale shares (like phoenixminer is misreporting them as stale when they are really incorrect) but I lowered the clocks to values I knew were running fine yesterday. I also changed my bios today using polaris one-click editor. I'm really not sure what could be causing all of these stale shares, maybe an issue with the pool?

Thanks!
