Random shut downs and reboots, no bcod

[Datsun240z]

Hey guys, I have random reboots on my computer. I dont get any blue screens or error messages, ive check temps and basic stuff but im not the most advanced tweaker like some of you. I can be gaming or surfing net or just sitting idling. sometimes it will turn back on immediately and sometimes it has to wait 10 mins or so.

-Maximus XII
-i910900kf AIO cooler with 320mm rad.
Rams (4) sticks of g.Skill f4-4133c19d-16GTZR--- might be the issue, ive tried it on different scenarios with 1, 2, stick and swapped them around and all that and ran mem test its test ok.
-1090ti
-(2) 960 PRO m.2 in raid
-1 970 pro m.2 storage
-corsair 1200gold PSU


I have some basic diag stuff but just tell me what to post.

Do i need to slow this ram down rather than speed it up for this processor (i9 10900kf)? see specs below. im running memtest 86 on it now. 2 sticks passed in dual chanel, i took them out and put the other set in the same slots and will be running that. if they pass ill put in all 4 and run it again.

both sets passed memtest, i havent ran test on all 4, ill do that in the morning while i go to work.

keeps crashing on 2 sticks at 3600. i think I'm gonna reformat and go to windows 11 pro. see if some software changes help any.

well, so far so good. cpu stress tests on clean install of windows 11 pro and only drivers, no aisuite or armory crate, temps are down a solid 20c


Edit. After 2:40 mem test the temps are waaaaaay down. I'm just going to keep it here and see what happens for a bit while gaming.


I did also notice a nice spike in watts which makes my temps spike which is usually just around the start of the tests. could this be an issue?
