9800 x3d overheating what is the stock voltage

[cou60]

hi

i think i have a problem with my new 9800 x3d,

the cpu is overheating like crazy and is throttling

when i run programm like prime95 and cinebench my cpu go over 90C and throttle to 5100 mhz instead of 5.2 ghz. the cpu was 1.2V in cpu-z


i tried undervolting and my cpu is now at 1.120V and can run cinebench properly at 76-78C but prime95 is still a problem, and the cpu only go to 4.7 ghz.

my motherboard is probably giving to much voltage to the cpu, what is the stock voltage for an 9800x3d at 5.2 ghz

my cooling is an 420 AIO

If prime is running avx 512 then the chip is designed to throttle at 4.7Ghz.

Your temps are pretty high for a 420 AIO, though, so I would check pump speed and mounting, you're getting worse temps I do on air.

prime is running avx 512

Air is better than AIO,

, i think the mounting is fine, my temps in idle are fine 30-40C i think i lost the silicon lottery again. what is your voltage

Make sure the wb doesnt have plastic on it

Make sure the wb doesnt have plastic on it

my temps are that bad ?, i don't have the plastic, this AIO was cooling an ryzen 7700x before

i think i just got a bad cpu. for fun i was overcloking a lot of old E8400 E8500 and E8600, some of them were cool and some where hot like hell

if your 9800 x3d is as good one and mine is a bad one, i will get hotter temps even if my cooling is on par.

Hot Take: Prime95 is no longer a good stability test. CPUs from AMD and Intel will both downclock and reach max temps at stock settings.
