Thanks for the quick reply. I checked your post but I don't really see anyone posting any solutions to this issue, unless I missed something? One person says clear the CMOS but I don't see what good that will do. My system worked perfectly fine when I had the R5 1600 CPU and GTX 1060 graphics card. Certainly we can't be the only two people experiencing this problem? Like you said in your post I believe it is the IGP throttling so why would overclocking the CPU portion fix that? It just seems like there is a bios setting or settings I need to enable to get a stable overclock in gaming. I don't even care if it's clocked to the base frequency of 3600mhz, I just need it stable and I'm sure that will fix the issue.
 
/Edit
I didn't see that there was a separate post about this. I've posted what you wrote here in case others want to see it.
 
How to fix APU throttling and unsaving settings
Go to the Bios (press DEL when system starts) -> Reset settings and reboot -> Go to OC Tweak tab -> Change CPU frequency HIGHER than base clock (ex. 3625) -> change voltage (ex. 1.25) -> Save and reboot. Now IGP will not bounce anymore and have stable frequency. Games stutters will disappear.
 
 
I followed your instructions and amazingly it worked the first time! I couldn't believe it - I did a couple of quick gaming sessions and performance was great and no crashing. In addition I figured out what the actual, real problem was for me. After I used your advice I reset my system and set my ram to 3200 MHz in the bios using XMP and my games starting crashing again! So, I changed the default voltage to 1.4v and now not only is my memory running full speed but it appears to FINALLY BE FREAKING STABLE. Thank you so much for the guidance! It never crossed my mind that the ram would have been the issue since it would always boot up to 3200mhz with no issues. I'm going to continue testing but (fingers crossed) hopefully I've got a stable system now.

Mate, look at my topic - http://forum.asrock.com/forum_posts.asp?TID=7834&title=2400g-troubles-bios-mysteries-igp-throttling

I have same stutters issue with 2400g and ab350 itx. It is IGP throttling.

Hello peoples,
 
I am hoping to pick your collective brains because I have run out of ideas on my own troubleshooting. I have had an Asrock B350M PRO4 mb + a R5 1600 CPU with a GTX 1060 6g video card (and DDR-3200 memory in dual channel) since about September of 2017. I built it myself with parts from my local Microcenter and I never really had any issues with it in that configuration. Jump to a week ago and I purchase a R5 2400g. Before I changed to the APU I made sure to upgrade the bios to the most recent beta (4.63) then put in the 2400 and that's when all the troubles started. I have been able to fix most of them with the help of google and YouTube but I can't find any videos or anything specifically on this last issue.
 
Basically the problem is this: I'm playing a game and it the performance/frametime fluctuates WILDLY, even if there is nothing going on in the game at that particular time. For example - I could be playing at around 80fps average and then the fps will suddenly drop to around 15-17 or so, then after about 2-3 seconds it will jump back to 80fps. It does this the entire time I'm playing and in every game I play. I do not have anything overclocked and have all the newest drivers installed from AMD as well as a new install of Win 10. Obviously this is annoying and makes some games feel near impossible to play effectively. Through much head banging on my desk I figured out a way to fix it and that is by overclocking the CPU. However, therein lies the catch. Whenever I OC the CPU (in the bios) I'll set it to something that the 2400 should easily be able to do - like 3700mhz at 3.69v. That should be more than enough voltage for the CPU part based on my research. I'll go into windows and verify that the OC indeed took and will even run various apps (Aida64, intel burn test, etc) and everything comes up with no errors. Temperatures are well within spec (I have a 240mm AIO cooler) so I know thermal throttling is not a cause. I can then jump into a game and the performance is MUCH better and much more consistent, which is great. However, it will only play about 3-4 minutes or so, freeze for about 6-8 seconds, then Windows will bluescreen with the error 'video_tdr_failure atikmpag.sys' every time. 
 
Does anyone have this board/apu combo and experienced these issues? I finally figured out how to set the IGP dedicated memory to 2G (thanks to this forum) but that does nothing to fix the issue. Upping the CPU vcore does nothing to help stability it just makes it run hotter :/  I'm hoping someone more knowledgeable in the overclocking arena can advise me on maybe what their settings are (for this model MB), or can tell me if I'm doing something wrong and let me know how to get a freaking stable overclock. If I can get to that point I THINK that will resolve all my issues. Any help would be appreciated, thanks!
