Ryzen 3900X Weird Temp Issue....

no idea have u re seated the cpu

Yeah. I went and got a 5950x to test with and the problem went away, I could get it up to 95C on purpose without issue. I put the 3900x back in and the problem came back. Seems I may have a defective processor somehow. No idea how that managed to get past testing but I guess it happened...

Hi y'all, I've got a 3900X giving me some weird problems. *Before I explain BIOS version has been updated a 4x times without fixing the issue*

 

So I used to have a 3600 on this board without any problems on a stock cooler I could touch 90-95*, last year I scored a 3900X for $300 used but noticed the second the Tdie hits about 83-84* the entire system just shuts off but never looses power. Screen goes black and it restarts like the CPU crashed. I've tried stock clocks with SMT on and off & with and without PBO enabled (On tended to crash sooner due to higher voltage targets) and a careful undervolt/overclock of 1.42V @ 4.3 SMT off to keep it cool (best result). 

 

I'm wondering if anyone else has had similar issues on Ryzen or my MSI board...After fiddling with the system for about a year I'm leaning towards a microcode update issue but I don't know how to do that or check what version I have, I assumed it updated with the BIOS but I'm not sure.... any help?

You're using the stock 3600 cooler on a 3900X ? Yikes ! No wonder it's crashing freom overheating then, you NEED a better cooler

Totally agree with @Shimejii and @PDifolco, you want to get a better heatsink. The 3900X may show a lower temperature but the higher TDP means it can overshoot faster. If you only want to play games, you can go into bios and disable cores. Going down to 6 cores could be enough until you get a new cooler.

 

One more thing, if you did remove the old cooler and put it onto the 3900X, there would not have been enough thermal compound left to make proper contact. If you have some you can apply more (more does not hurt). Also adjust the fan curve so that cpu fan will hit a screaming 100 % speed at around 70C. 

 

You want to find yourself an aftermarket cooler. Small tip, if you can find yourself a used Noctua cooler like a NH-D14 or D15, you can get an AM4 upgrade kit for very little money and have a great cooler, if one is on the market. Otherwise check reviews and see what's in your budget. Any tower cooler with a fan 120mm in diameter or greater will do better than the stock heatsink. If you want to go with water, A 240mm AIO would be the minimum for this processor. 

 

Good luck

Sorry I should have clarified this is on a Corsair 240 AIO and with a NHD14. The AIO works a little better then the air cooler but both have the same issue at the same temp

 

When I had the 3600 I used the stock cooler, right before getting the 3900x I got the NHD14. Upgraded then the crashing started so I got a AIO which helped but the 83-84C temp issue stayed though its harder to trigger that temp with the AIO it still exists

hmmmmm have you tryed to resocked the cpu and made sure taht the thermal paste covers the whole cpu as there is only temp sencors on some parts of it so if you dont have good contact you can have the issues ur describing

Yup spread is perfect and making great contact. Happen to know how to update the microcode or does that update with BIOS?

Yeah. I went and got a 5950x to test with and the problem went away, I could get it up to 95C on purpose without issue. I put the 3900x back in and the problem came back. Seems I may have a defective processor somehow. No idea how that managed to get past testing but I guess it happened...

Your CPU & GPU should not be used above 75C, I can't rate a cooler unless you setup your Bios CPU Fan to 100% at 60C and then it failed.

But with any newer CPU used intensively, get a water cooler, they're not that expensive anymore.

First as stated, the temps achieved were on water. Second processors are rated to a safe temp usually around 95C. Anything under that is considered operational temperature.

Welp, "you know best", I tried to help, I can only lead a donkey to water... 🤬

Please, don't listen to the experts, run that CPU at 95C at all times. You know best, that's why you're here asking for help.
