Stock rx5700xt crashing cannot go past 51.6 mh/s

i have 4x 5700xt and if i use anything else than teamred it crashes anything i try to do to go near 53 mh/s makes it crash the msi hynix card only does 50.7 mh/s seems low for stock cards still ? note there was rx580 plugged on the system before does it have anything to do ? if i try phoenix or ethash mh/s is higher but crashes…

Get new usb stick and burn new hive on it.
Find here good stable core/mem settings and have happy mining
