My case: evga dark x299, 7820x, PSU1000 seasonic, gskill 8Gbx2 3000 and Gtx 1080ti. I use for daly works, relax,... not for hard Oc.
The problem: whenever i remove the power AC from the switch, the ratio limit is turn back x45. I set in bios that default optimize(the cpu ratio limit will max in x43), ram 2666, the power ac still plugin so i reset or sutdown it still right, x43 and ram bus 2666.
But when AC power removed from switch about 5 minutes, the ram bus or any things i set in bios still right, only what things a set onl Tab cpu were changed, it turned back x45 all cores. If the cmos dont save why the ram bus or any things still right? Only the cpu changed.
Many thanks for your help.
