--- Comment #33 from SF <shitman71@hotmail.com> ---
I did replace the 14kw thermal grease with a 6kw thermal-pad, the watercool=
ing
i use is only made for am3 so it doesnt get enough contact with grease. 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.
