It can be many things, including CPU, RAM, BIOS issues, etc... Hard to tell.

So sad:(  Thanks, anyway.

I guess your system is just very sensitive to even the slightest overclock...

So the highest possibility is motherboard problem?

Have you tried it at default settings, without any overclock?

Yes, and the test went well. A little oc, boom! I've tried the latest version of AIDA64 and the latest beta version of AIDA64. The problem was still there. What's wrong with my pc?

Hey guys, there is something strange happened.

ryzen1700, asus b350 plus, bios version 0805(latest), windows 10 version 1703(latest)

Bios default settings, everything is fine.

Bios optimized settings, which is only overclocking CPU to 3.65ghz( memory clock is default 2133) . And I can't complete the Cache and Memory Benchmark, my computer black out during the copy phase every time. The system stability test works fine, the CPU temperature maintained about 61°.

How can I fix it?
