Efficiency tips?

My 3080 trio x is currently undervolted at around 1200-1250 mhz core clock at 737mv. Memory clock is 699 but I heard that memory doesnt do much on RVN

On nicehash this brings me to ~90mh/s at around 205-210w. When I mine rvn, the wattage is closer to 250, as if I didnt undervolt at all. Hashrate is 47 on the top of my head.

Any tips you guys have for better efficiency, or is this as far as i can go for now?
