Paging doktor83, please help

I struggle with 1.8.8 on my vega56 rig.
https://i.ibb.co/zWdbLwt/Screen-Shot-2019-05-26-at-1-43-10-PM.pngI have a decent hr on cn pico (turtle) but cnR i have horrible and unstable.
Should i raise core clock? Mem clock is pretty much at max (hynix memory) and it can't get over 910.
What are optimal settings for vega56 on cnr?
