Hav= ing problems with it... After booting i recognised the machinge is now crashing over and over again short after boot, same as it was friday. BIOS shows 70=C2=B0C+ temperatures after crash, i switched back to air-cool= ing because i am out of thermal-grease and cannot use the watercooling anymore. First thing happened, i needed to switch back to 2800Mhz ram speed because = it kept crashing again. It also did crash exactly the same way with watercooli= ng and thermal-pad at 3200Mhz. Do you know what? I think Ryzen just has a heating-problem. High ramspeed causes more heat, power-supply affects heatingproblems and the switching from aircooling to watercooling making it stable explains everyth= ing. I cannot test it now, i dont have money for putting the watercooling back. --=20 You are receiving this mail because: You are the assignee for the bug.=
