I reported this yesterday here http://forum.asrock.com/forum_posts.asp?TID=8075&PID=47916&#47916
The only temporary fix is to lower your CPU voltage (with a negative offeset, try -100 first cause its the lowest offeset available and test from there) this will lower the frequency of the throttles but not eliminate them

Early on when Ryzen launched I would get hanging in games on my 1600x for about 3 - 5 seconds then back to normal (usually with me dead lol). 

In the end a windows update fixed the issue, after months of scratching my head, trying different components and OS installs. The turbo theory certainly seems to be in the same vein, worth a shot.

Good luck Thumbs Up

I will try both, custom setings and reducing voltage / offset.

Let's see what we can do. It would be great to play that game on this machine, freakin great to be honest.

See here a little more info http://www.apu.graphics/tipps-and-news-for-ryzen-2400g-throttling/
There is also some talk about SMU 30.68.0 fixing the trottling, the latest available bioses have 30.67.0 so we dont know for sure until ASRock releases updated bios
You can check your SMU (which might stand for System Managment Unit) version by going in Advanced/AMD PBS/Firmware versions

Ok I'll check that too and let you all know... so it may be though a bios/board issue in that case.

Fortunately MOST of those things can and will be fixed someday. Given the fact that the Ryzen APUs are quite new I'm positive and looking forward to seeing some major improvements in the near future. Anything else would be a shame for everyone... This doesn't only mean board manufatorers and AMD themselfes, also Microsoft and all the game developers should get their asses up ;-)

Ok, here?™s an update!

First of all, no more freezing since 4.51! That?™s great!

I checked SMU version, it?™s 30.67.0 as we expected.
Next I set the CPU to 3700 at stock voltage.

As expected everything worked, frequency was fixed to 3,7 Ghz which is ofc not optimal but for testing ok. I fired up the game and played about an hour, no stuttering anymore! That worked! Performance @1080 is still not the bes on medium settings bit way better and playable!

Further testing needs to be done now.

Interesting finding, could you please tell us what CPU cooler do you use, and cpu fan profile on uefi?
Are the stutterings gone with Default UEFI settings, or with fixed voltage and CPU clock at 3.7GHz?
Could you also please test the SATA bugs?
Enter Advanced/Storage Devices and switch SATA Controller to disable then reboot and press F11 and tell us if the uefi still lists your SATA drives.
The 2nd SATA bug is if you put your SATA drives in the 4 different ports and press F11 to boot from them it will list the port number wrongly (the port number is after it states AHCI Px, x being the number of the port)

EDIT: See here http://forum.asrock.com/forum_posts.asp?TID=8075&PID=47818 all the bugs I personally found, if you could check to see if your configuration exhibits any of these and report back I would appreciate it

I have the throttling issue too, but I am using the ASRock AB350 gaming ITX/ac motherboard with the 2400g processor.

I was getting really bad, regular drops in framerates in PUBG.  Here is the fix I discovered, and I have no more problems at all.  I simply applied a 350MHz frequency to the GPU with AMD Ryzen Master Utility.  The CPU still has turbo enabled.  I'm guessing all this did was turn the GPU turbo off.  

Using a higher GPU frequency also fixes the issue.  I would have liked to use a higher frequency, but I'm smashing up against really high CPU temperatures under load when using the stock cooler, like over 90C.  I have a new cooler coming and I hope to be able to crank the GPU frequency back up.  

Here's my theory: It's possible that the issue is that the turbo for the GPU hits some kind of safety limit, and it throttles way back.  Once the whole system is choked to almost a stop, the temperature (or power or whatever) drops way down.  Then turbo goes back to normal operation, and repeat.

[URL=][/URL][URL=][/URL]Ok, here?�s more details for you

I fixed the CPU frequency and voltage by enabling manual mode in uefi. I overclocked the cpu 100mhz just to make sure it uses my manual settings.

My fan profile is now set to performance mode and I turned off the cool&quiet feature.

I will now systematically test which of the settings did the job.

My temps are not causing the issue, I checked temps while running the game and it never went over 60-65 with stock settings. Now with fixed 3.7 Ghz it goes up to ~70 after an hour of AC Origins which is still OK for an air cooled SFF PC.

I will also try setting a manual GPU clock speed with the Ryzen tool, this would be much more comfortable because I could simply do this when needed.

I can also check the first SATA issue, unfortunately I can?�t do the 2nd because my PSU cables are blocking almost all the ports and I really don?�t want to rework all the cablemanagement today :-) I will have to do this soon because I?�m going to insert a M.2 SSD...

Interesting, I think the issue was fixed by going manual on the CPU/GPU frequency and voltage, so it would seem to be a AGESA or motherboard issue, ASRock needs to look into this, because in its current state CS GO is unplayable for example and many more, please do check the 1st SATA issue and report back. Regarding the 2nd one, you don't need to move anything, just look at the motherboard where the SATA ports are, they have the numbering printed on the PCB, then just press F11 when booting and confirm if the naming is wrong for the respective ports :) 

Thanks for checking these out
