Random Framedrops

[Guest]

The problem:

After a motherboard change I started getting random framedrops in GTA V. Now, after some time analyzing, I have found that the framedrops seem to occur only in performance-hungry games like GTA V and Arma 3. Also, they do not seem to depend on what I am doing in the game. Every minute or so the game starts to give me about 5 FPS with the frames lagging behind the actual game. Then, after about 10 seconds, everything goes back to normal. The framedrops usually start when I've been in the game for about 10 minutes.

 

 

The (non-) fixes:

• I updated the drivers.
• I tried changing the motherboard back.
• I tried both motherboards with both graphics cards.
• I changed the hard drive (but it's a mirror).
• I tried reinstalling windows.
• I looked into the thermals because the problems only started after some time, but they peak at around 50°C for the CPU and 65°C for the GPU.
• I installed a dedicated PhysX-card.

Non of those worked.

 

 

The system (nothing is overclocked):

 

• CPU: AMD FX8350
• GPU: Palit GTX 970
• PhysX: Palit GTX 750ti
• MoBo: ASRock 970 Extreme3
• RAM: 24GB DDR3 (2\*8 from the same manufacturer on 1 and 2, 1\*8 on 3)
• PSU: 730W Xilence XP730RS
• HDD: 2TB
• Display connection: DVI from card to VGA at the monitor
• CPU cooling: Coolermaster Seidon 120V push-pull (out)
• Case fans: 4 (3 in, 1 out)
• Some more stuff like USB cards and card readers

 

 

Please help! I'm at the end of my knowledge.

 

EDIT:

I've uploaded a clip of the problem to YouTube: [https://youtu.be/U\_731fu1SJQ](https://youtu.be/U_731fu1SJQ)  The quality is pretty bad, but you will see what I mean (00:23 - 00:35). The bad quality amplifies the effect, in reality the game is still somewhat playable.

The 8350 might be too weak for the 970. Try with 16GB of ram in dual channel mode.

As to the 'processor too weak': I had the CPU-GPU-combination before and it worked flawlessly. It's only after the MoBo-swap that things went downhill
