Cant tell if my motherboard is causing bottleneck

Hambone64 · May 25, 2015

System specs:
Mobo: msi 970a g43
CPU: 4.0 ghz AMD 8350 FX Black ed.
GPU: Nvidia GTX 970
RAM: 8GB 1600 mhz ddr3
Power Supply: 680 watt

Ok so I recently upgraded my motherboard, CPU, and graphics card to what you see above in hopes of running GTA V at 60 fps. after I upgraded and installed everything I definitely noticed a vast improvement from what it was before but i get frequent frame rate drops while playing. the drops are not horrible but it does not run at a solid 60 like it should. Even after I lower all the settings considerably I still get a considerable amount of little frame rate blips.

In order to try and solve this I have freshly installed windows and the game itself obviously. Also have updated all the drivers on my mobo and GPU. also I tried overclocking the GPU to a core clock of 1400 and a memory clock of 8000 and I gained frame rate but the drops still continued.

My question is could my motherboard (or any other components) be causing bottle-necking on either my CPU or GPU or is this an AMD issue? any advice or recommendations would be appreciated

A overclock on the CPU may help. Mobo is not that great and part of the issue. The GPU is fine and not the issue. Also a small ram oc to 1866 might benefit some too. You should try getting a i5-4460 with a GIGABYTE GA-Z97-HD3 mobo would help the FPS a lot.

Since lowering the demand on the graphics card does not change anything, I would suspect the cpu.
Your motherboard is considered a poor one and not fit for overclocking FX8 or FX6 chips according to this:
http://www.tomshardware.com/forum/id-2384024/motherboard-tier-list-970-chipset.html

You could also try these tests:
Limit your cpu, either by reducing the OC, or, in windows power management, limit the maximum cpu% to something like 70%.
Go to control panel/power options/change plan settings/change advanced power settings/processor power management/maximum processor state/
This will simulate what a lack of cpu power will do.
Conversely what a 30% improvement in core speed might do.

You could also experiment with removing one core. You can do this in the windows msconfig boot advanced options option. set the number of processors to less than you have.
This will tell you how sensitive your games are to the benefits of many cores.

If your FPS drops significantly, it is an indicator that your cpu is the limiting factor, and a cpu upgrade is in order.

If you have a cpu problem, you will just need to live with it or spend a bunch for a intel cpu and motherboard change.

My CPU should not be the issue. It is the recommended CPU for the game and other people who have the same CPU are running it just fine. buying a new CPU is not an option for me. There has to be something else going on here.

I only know of one 680w power supply and that would be the Apevia power supply which is low quality. There are a few things you could do though for testing purposes. Number one would be to make sure each PCIe plug to your GPU from your power supply unit (PSU) has it's own dedicated rail by making very sure you are using separate PSU strands for each plug as that power supply is a split 12V rail PSU - that is if you are actually using the Apevia.

Secondly, though the board lacks mosfet VRM cooling, if you happen to be using the stock cooler I would highly suggest installing a Coolermaster Hyper 212. It would accomplish two things. One, keep the FX 8350 cool, and two, spread air over the VRM section as well.

I would not have one of those PSU's in my house or anywhere near it. It should not even be ethical to sell one.

Tier Five
Avoid IMMEDIATELY. These units are highly unsafe to use. No such protections added, very thin gauge wiring used, false advertising and too much to list. Reference to a higher tiered unit for a better, money saving and a much safer unit. For your safety's sake, please don't order or pick one up for use in your system. These units are a potential fire hazard and could even kill you, let alone your system.
