I wanted to do the FIT test on my ryzen 3900x to check what voltages I could use for an all core oc, following a video of buildzoid https://youtu.be/b9oV69bYQq4?si=RO4u1S5-DLWW5zxc
Sadly, I could not get prime95 running stable, even at stock settings for cpu and ram.
After a few seconds, my cpu load drops on all core all the way to zero, my ppt drops to around 80w and my voltage rises again to 1.3v. The clocks in the cores also rise to 4.2ghz, which is where they sit under low load for all cores like gaming.
But I pass the test woth 0 errors.
Temperature max is 74.4°c
My question is why my cpu won’t run prime95 at stock and where the problem could be.
I pass other Stresstests like occt without problems and my cb23 score with xmp and pbo is at 18540.
Runs perfectly fine at all other times.
