https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D219399 --- Comment #19 from SF <shitman71@hotmail.com> --- To me it is the complete opposite, my system runs too hot. Up to 70=C2=B0C = or higher under full load. Changing Voltages to lower values and power-settings to what i described improved it to me, my system stays far longer running before crashing. With= far longer i mean it runs several hours under heavy load while with default-settings it only runs less then a hour before crashing. We are using different Mainboards which means they have different solutions delivering p= ower to the cpu but in general i did read this from several people having improv= ed their crashing-problems by changing power-settings. You can try setting your ram manually to what is inside xmp but this didnt = made any difference and i tryed all kinds of settings, even custom. All you can and need to do is changing the values tCL, tRCD, tRP, tRAS. The= se are four, not five. Only setting these values will make a difference to my experiences. Put command-rate to 2T, 1T is always causing crashes to me. 2T= in generals i known to be much more stable then 1T with minor performance-impa= cts. (2-3%) You might also check your ramvoltage, if you did forgot this. Increasing he= lps for higher performance, decreasing gets you more stable. Don't place more then 2 rams into your system, ensure they are seperated fr= om each other. This will increase stability and performance. Single-ranked ram= is also more stable to higher frequencys and has more performance then dual-ra= nked but dual-ranked is more efficient at costs. Dual-rank will outperform single-ranked ram if they are on equal frequencys. https://www.amd.com/system/files/2017-06/am4-motherboard-memory-support-lis= t-en.pdf You can use higher rams at your own risk, i know some people did reach 3600= Mhz with my ram already. I can only achieve 3333Mhz. --=20 You are receiving this mail because: You are the assignee for the bug.=
