5700XT Help! Crashing over 1770 Memory

So I’ve been chatting here and there with Bick but I figured extra help couldn’t hurt. My 5700XT Rig is having hell and crashing like crazy when I increase the memory clock beyond 1770. I’ve increased page file size, I’ve added ram, I’ve played with the phoenix miner settings, I’ve double check Temps, and now I’m stumped. I’ve been told I should be able to run stable at over 1800 on the memory. Any suggestions?

reason run over 1800? btw tune need do with msiafterburner not with miner software
