So I have made many topics regarding my R9 390, but I just don't understand why my R9 390 just does so poorly compared to unclocked benchmarks on YouTube. On the division I see R9 390's with 60 fps constant on ultra settings, not OC'ed the only difference is the CPU, and ram. (mine is OC'ed to 1065 core, and 1565 memory.



My specs are R9 390
FX-8310
8GB single channel RAM(Plus readyboost USB)
HX750i PSU
M32BC Motherboard (specific)
 
Solution


More than likely this is the case. You can try OP, but you're running the risk of damage. And replacing anything costs money.
Not to mention, to OC you need a decent cooler. That certainly won't have been included in a sub $500 desktop!

Ultimately what you're trying to do is akin to drive a car with no money for gas.


Lmao oh okay
 


Looking at whole CPU usage is never a good thing, each core is what matters, and even if it's below 100% it can still bottleneck since such software only takes the average over a time period.
 

Its been long time since I bought. What should I do?
 


Nowhere near enough to remove the bottleneck, no.

At this point, you either only have these options:
1. Accept you're running a bottleneck, and will never see the full potential of your GPU.
2. Upgrade your CPU only, to a higher clocked CPU that will OC better - this will remove some element of the bottleneck, but your options are limited, so you'll still not see the full potential of the GPU.
3. Upgrade your motherboard/CPU & likely OS to remove the bottleneck - not a cheap option.
4. Sell/return your GPU and pick up something that will not be bottlenecked (or at least not much). A GTX 950, for example.

Ultimately, the 390 was a total waste of money when pairing it with the FX-8310.
 


I would go for i5
 
Well it may be that certain cores are being maxed out entirely and holding back performance, while the game may not be using the other cores that your CPU has available. In gaming, clock speed (and instructions per clock) matter more than core count... As long as you meet the game's requirement for core count, that is. I would also say that using a USB drive as a ReadyBoost drive to boost your gaming performance probably isn't going to yield great results. You may see an increase in performance, but probably only marginally. And also, single channel memory... That means that the system can only interface with one stick at a time, which decreases total potential throughput of your RAM if you had a dual or triple channel setup.

All in all, I just don't see the R9 390 being a good choice for your CPU and RAM. If you didn't have the money for a higher end CPU or RAM, I would have gone with one of the AMD A-series APUs and then got a MOBO that supported at least dual channel and then utilized both channels rather than trying to use USB flash drive as a form of RAMDISK. And here's why http://www.pcworld.com/article/2360306/usb-3-0-speed-real-and-imagined.html

I hope I helped... I wasn't trying to start a new argument within the argument that's already going on.
