Ryzen 5 3600 boost problems.

[Pleo]

Guys,

 

I'm having a bit of trouble with my R5 3600. (Either that, or I do not fully understand Ryzen yet).

 

When gaming, My cores never boost to the advertised GHz (4.2). They fluctuate from 4075Mhz to 4050Mhz to 3975Mhz.

 

When playing games like BF5, I'm experiencing some stuttering. It looks to me that the cores are not fully being used to what they're capable of, since they're fluctuating.

 

Using the Ryzen Balanced power plan, PBO is on (In BIOS), A-XMP enabled (3200mhz 16gb ddr4 ram, cinebench r20 I'm scoring 3420 on multi (71c full load) and even then the cores barely hit 4Ghz.

 

Is there something i am missing? Using a MSI b450 tomahawk.

 

Thanks

I think the advertised 4,2 ghz is single core,so it's normal it boosts to 4 ghz all cores

What about the fluctuating in cores? You think it's because i've enabled Precision Boost Overdrive? (The rest is on stock, voltages etc.)

Temps?

When gaming, 60-65. Stress testing max 73c so far. (Cinebench R20).

I never had any luck with my testing of the Ryzen balanced power plan, results were all over the place but that was with a first gen chip (R7 1700). I found better results keeping my power plan to High Performance all the time. If that doesn't work, try going into the bios and disable "AMD Cool & Quiet", this feature downclocks your frequency when it thinks it is not required. If neither options work, try a manual overclock to keep the processer running at a certain speed. Maybe start with an overclock of 4.0 while leaving the voltage on auto.

As far as the cpu not reaching 4.2, only 1 core will likely boost to something like 4175mhz.

I used to have a Ryzen 7 1700 and while playing PUBG I would experience a lot of stutters. After some diagnostics I discovered the cpu was downclocking itself while under load when these stutters were occurring. After disabling "AMD Cool & Quiet" and entering a manual overclock of 3.8 the stuttering didn't happen again.

I've read that with cool and quiet disabled you can brick your cpu. Is this true? Also, this solved the problem for me as far as idle temps go. I would be at 1.4 VOLT on idle. With Cool 'n quiet enabled, my idle volts and temps went down. 

[Brent744]

Wow that's a lot of voltage considering it's set to auto. I've never heard of the possibility of a bricked chip by disabling it, I would think if that was a possibility AMD would've removed the option to disable it. I did however hear that the new chips do run a lot hotter than first gen and Zen+ chips. Maybe keep that thing enabled to be on the safe side.

Strange, I have the X3600 running on a Hyper 212 Evo and get 4.2 regularly at under 62c gaming at 1.43v. I have Ryzen Master with PBO running, Windows Performance and energy at Best Performance. Did you install AMDs chipset drivers? Dont use the MOBO manufaturers chipset driver.

Look at Chipset drivers, other then that it depends on Temperature headroom, Windows settings set to balanced does not help, set it on performance. Cool and quiet as an effect on idle temps and clockspeed. Don't worry about those high voltage at idle, it goes up to 1.5v on load spikes, the 7nm process is so quick that even the smallest amount of load increase voltage really fast then down really fast, so you see an average on how quick the monitoring software can read it.

Ryzen Performance or Windows performance?

Are energy settings (Best Performance) Seperate from Windows performance (Power plan)? If so, could you tell me where i can change the energy to best performance?

Thanks. I've only been using Ryzen Balanced ever since. Will be trying Windows high performance power plan and change the power mode. Hope this will push my cpu a bit more.
