Hi, so I've recently completed my build with a MSI R9 380 4GB and FX-8320 at stock clocks. Here are my full specs: http://ca.pcpartpicker.com/p/X2j7bv
The problem is that I'm experiencing unusually low fps in all my games. Let's take Dirt Rally for example; I have everything maxed out at 1080p I'm only getting an average of 30 fps in the game's benchmark tool, and around 20-40 fps when I'm playing. This is very unusual, people running the same setup with a R9 280 or 285 are getting much higher fps, all 60+ fps.
Now here is where stuff gets WEIRD. MSI Afterburner shows my GPU usage is constantly at 95-100%, which I assume is a good thing, but my CPU usage is stuck at ~10% and rarely hits ~20%+ fps. My CPU temps are ~50 degrees Celsius when gaming, and my GPU temps are at 60.
Now here is the big issue . Since my GPU seems to be running at mostly full load, I'm guessing the CPU is the problem here. I've read online that the FX series have thermal throttling issues; in HWMonitor, the 8320's clock speed keeps jumping from 3700MHz+ to 1400MHz, and I suspect this is causing the massive fps drops. For example, in X-Plane 10 (a flight sim that's heavily CPU dependant), my fps is at around 15 and barely changes no matter what graphical settings I use.
To make matters worse, the CPU usage per core is usually at 10%, and rarely hits 20%. I know some games don't utilize all 8 cores, but shouldn't the first few cores have much higher usage, like 50%+? This is happening in all games, including Dirt Rally, X-Plane 10, and EVEN Unigine Heaven. In Unigine, I'm only getting 25-30 fps with everything on Ultra at 1080p, although people with GTX 960 and FX-6300 are scoring 40+ fps. I've heard that disabling AMD's APM, C1E, and Turbo Core. Will this help with anything? Here's the source: http://www.overclock.net/t/1202751/amd-fx-cpu-throttling-fixes-please-sticky
I can't try it right now because I don't have my PC with me, but I'd really like to get this issue out of my head. One last thing, my motherboard has a 8+2 power phase I believe, so it should be adequate for the CPU, but does it have a heatsink on the VRM?
Any help is GREATLY appreciated!
