Rx 5700xt XFX card , Phoenix Miner 5.4c and constantly crashing

Hey, I am currently having one card crash in the phoenix miner setup.

Its set to
80
1330
775/775/1300
900
150

and is a Radeon RX 5700 XT 8176 MB · XFX
Micron GDDR6 · 113-230LNAVIXT612_8GD6_MS_W8

What happends is that it stops running in the array and then Invalid shares spread across. and the host reboots (phoenix miner feature)

Temperatures arent an issue and I am using 2x power supplies so there ample current.

Any thoughts on a stable clock for this. I should get 55MH

Phoenix miner sucks, use NBminer
