cpu ryzen not boosting

[Joker-_-Glitch]

ryzen 5 3600 not boosting to 4.2 
it will not pass 3.6 on the stress test

(biostar b450mhp)

[191x7]

Latest Bios?

Which stress test are you using to test with? If you're running at the default power limits in something like Prime95 for example it will run into those limits and more than likely run at or close to base clock. 4.2 is the rated single core boost clock, and it will not hit that when you're maxing out all cores in a stress test like Prime.

try a cinebench (2024 and r23) and Aida 64

I would expect a bit higher than 3.6 in Cinebench honestly, but I do believe R23 and 2024 are a bit heavier than older versions, so perhaps that's just your cpus limit in those workloads. What kinds of temps are you getting? You can try enabling PBO in bios to see if the higher power limits allow it to boost further, but you're probably going to max out around ~4GHz or so with default PBO. As a 3900x owner, I can tell you I see around ~4.15 GHz in Cinebench 2024 with PBO enabled, so I wouldn't expect a 3600 to hit much higher than that without manual overclocking. 3000 series just didn't clock that high to be honest. But you are hitting at least 3.6GHz which is the 3600's base clock, so it is running within spec. So as far as I know everything seems to be working as it should.

 

Definitely check your temps and try enabling PBO though, if you want a quick and easy way to get a bit of a boost that's where I'd start. I wouldn't bother overclocking with Zen 2 though to be quite frank. Any gains you may get would be negligible. Zen 2's biggest weakness was the split CCX design, and really no amount of realistic clock speed gain you'd get is going to offset that. That's where RAM and FLCK tuning comes into play, but that's a whole other thing entirely.
