My Ryzen 2700 can't pass stress tests

[FiliDapura]

Here is my build:

Ryzen 2700(non-x)
Asus B350 strix
teamgroup ram 3000mhz (Qlv approved)
Evga 600 bq psu
Msi rx 480 gpu
Cryorig h7 air cooler

So i've been tweaking with overclocks but can not seem to pass any stress test for more than 9 mins. My cpu, in various settings, failed aida64 in less than 2 mins and prime95 less than 10 mins. And sometimes it'll pass cinebench. I've been aiming to get 4ghz stable at voltages between 1.275-1.35 but it keeps crashing during prime or aida.

What i've checked:

-Bios is up to date (latest was released today).
-Left everything default after changing cpu ratio and voltage.
-Changed LLC to high
-Enabled Core performance boost
-I made sure all the necessary software was installed such as the latest chipset drivers.
-Cpu temps were in normal parameters (34 idle and 75 load).
-Tested stability at complete stock settings, which passed.

I'm new to oc so i know there's something i did wrong/missed. Any ideas what i should try? Thank you in advance!

I'm not so sure that you did anything wrong. It's just that some CPUs don't overclock.

Overclocking is a lottery in some ways. Some chips will clock like no tomorrow, others just stock.
