Ryzen 9 3900x can't even stand CPU Z soft stress test

Why it crashes:
Old BIOS version
Old Chipset driver
Unstable RAM settings
Poor cooler point causing problems with heat
Potentially more messed up settings

Clear CMOS, update the BIOS and chipset driver and mount your cooler properly. The Noctua cooler shouldn't be doing worse than the stock one.

Im trying to stress test my CPU at stock speeds with CPU Z, just to compare temps with my old Thermal paste but surprisingly it cant even take it for 40 minutes straight, again im not overclocking anything, my cooler is an NH-D15s from Noctua, computer restarts at some point between that time just like an overclok fail -take note im not overcloking-

 

Just to make things clear, my BIOS RAM settings are tweaked, i lowered the CAS numbers and changed other settings with the DRAM calculator for Ryzen, making BIOS settings default helps CPU hold stress test for much longer (haven't tested yet but i stopped manually at 1 hour test) problem is, with default BIOS configuration computer bugs after loging on form sleep mode, it just freezes and stop responding indefinetly.

 

I understand CPU Z stress test is a very soft one, cant explain why it just crashes, ¿any clue about BIOS settings or freezes after loging in back from sleep mode?

If this is a new build, always get it stable on stock speeds, first.


Did you test boot it, before you built in into the case?

WHY NOT...?!

I'd guess it isn't the CPU but the RAM.  And I'd wager that's a voltage problem.

Doubtful. Over the past 20 years working with tech and on forums - I've ever only seen two instances of a defective CPU. It's incredibly rare, borderline non-existent.

Gonna check all of them.

Changing the Loadline Calibration of CPU to default (Auto) helped, ill be watching for further test with different programs, what bothers me now is the sleep/wakeup function crashing and freezing computer to the point of starting at windows recovery blue screen for no reason. Ill be notifying after doing all your sugested steps, thank you

Yeah, update everything and return to stock. This is why any overclocking utility always comes with a warning, when you change from stock, nobody can guarantee what happens next.

Your advice solved all listed problems, all check! back to stock, even better tempertures with new BIOS, bought my 3900x  too early, i think thats the problem with new stuff Specially Ryzen. Thank you so much

It's more to do with the board vendor being useless. Let me guess, MSI or Gigabyte?
