Mobo: Asrock 970 Extreme4
CPU: AMD FX-8350 4Ghz (Coolermaster Hyper 212)
GPU: EVGA GTX 760
RAM: G.skill 2x4GB
PSU: Antec 80+ Bronze 750W
HDD: 1TB and 2TB
OS: Win 7 Home OEM

All settings are stock, as far as I know. If it was overclocked right out of the box, I have not messed with it. Best way I can describe this issue when gaming is that the FPS drops tremendously (120 to 30, or 60 to 20) for maybe a few seconds, then pops right back up. Usually occurs when particle effects happen, like dirt being shot up from an explosion (Bad Company 2), or when there are a high volume of objects being loaded or moving (Witcher 3, Warband, Total War). I cannot recall having this issue with my previous Phenom II X4 955. If there was a framerate drop it would persist from the onset, not drop and rise, again and again.

I realize for games which are high performance like Witcher 3 this might be expected. However, I played and beat the game before without this issue on my Phenom, and games like Mount and Blade: Warband or Bad Company 2, I'm pretty damn sure this should not be happening at all, unless I am retard and seriously bottlenecking with the GPU or CPU.

I am beginning to suspect it may either be my motherboard, CPU, or both. I have upgraded and replaced all the components listed above except for the motherboard and the PSU, which I've had since I built my PC in 2011. The FX8350 I have had since 2014, though it has seen less than a year in service (I was lazy to install), and the motherboard BIOS had to be updated as it would not recognize it at first.

Hear are some screenshots with MSI Afterburner when playing.

Witcher 3
Bad Company 2
Warband
Typing a word document (no downloads in background, not sure if normal)

The huge drops for the CPU and GPU in the Witcher 3 and BC2 was when I alt-tabbed to get a screenshot, and I see that my GPU is hitting the ceiling when in Novigrad. But my CPU is also hitting the ceiling, even though officially it is a recommended CPU spec for the Witcher?

And a couple of videos showing the effect:

Witcher 3
Bad Company 2

As you can hopefully see, the frames get real choppy then returns to normal. Is my motherboard just not compatible with the CPU? Is my VRM getting too hot? Any help is appreciated.

The motherboard is compatible, but absolutely not optimal. It does not handles 125w cpus very well. Your stock cooler would probably perform better for you since it blows air down on the vrms. If you can add a case fan or two that will provide airflow to the motherboard, it will help. There is no REAL fix other than getting a better motherboard, downclocking your cpu, or getting a 95w cpu.

Your motherboard is compatible. The 970 series is compatible with the 8350. What i'm not sure is if the Vreg that is the culprit. I think the earlier extreme4 had some issues. Could possibly be that.

But what i see on the Witcher video is akin to the the game taking that moment to load/populate the area with effects. There is an off-chance that at these moments, your HDD isn't relaying this information quickly enough. Have you tried cranking the settings down to test?
 
the fx-8350 does not work well with this board just load the Asrock utility and prime95. you'll see the multiplier drop to 7x to keep the weak VRMs from overheating. That translates to FPS drops in heavy gaming. Once you replace your motherboard to one that could handle the Fx 8350 without a bios update your be fine my brother had the same problem as you with the same motherboard and after he replaced it with a SABERTOOTH 990FX R2.0 everything runs great for him now

From what I've gathered here: http://www.overclock.net/t/946407/amd-motherboards-vrm-info-database

Max TDP is set to 140W, Phase is set 4+1. Plus there's a lot more good information out there.
I kinda wished I looked at this a bit more when I got my MSI Gaming 970. (should be fine not overclocking) had no VRM problems with my ASUS M4A89GTD Pro (/USB3)... I did have others like AHCI and USB3 not working.


YOUR Performance could also tie into RAM, I noticed a significant amount of degradation when I went from 12Gb to 8Gb. It could also be bad caching of data from the HDD to the GPU. Other programs running in the background etc.

Yes, I've turned off the turbo core setting in the BIOS and that seems to have fixed my Bad Company 2 issue, and to some degree the Witcher, FPS still drops like a brick but it's not super slow like it was in the video, and for Battlefield, its barely noticeable.

Some other threads I've read with similiar problems suggest turning off 2 cores and messing with the power management, mine is still auto, I'm not sure if I should mess with that. I also changed the processor power management from minimum and maximum to 99%, though I don't know if this helped.

Cyber-freak, I read about the power phases too, and how it could be that I'm not getting enough power. I had thought about upgrading the motherboard like ezskills said. So the issue is that my mobo is compatible with the CPU, just not optimally?
