CPU Usage Drops Down While Gaming.

[Ben-Gay]

I know there is a tons of thread like this but i looked them and i didn't get a solution for me.So i realized this issue when playing Dark Souls 3.It drops down on the other games too.Usual usage is %30-40.But when fps drops start, it drops down to %10-15.My cpu temperture is generally 70 C when gaming.As i know it is normal.It never happened before.So im wondering about this.Hope you help me.

Here are my system:
AMD FX 8320 3.5 GHz (8 Core)
Nvidia Geforce GTX 760 ( MSI)
8 GB RAM

But you play some time (like 10 min) on high fps, and then the lag starts, right? Or all the time is low FPS?

Like you said i play about 10-15 minutes.After that starts lag and Cpu usage drops to %15.

OK, a lot of people have this problem, follow the steps:
1) Open your PC case.
2) Put a fan next to it and turn it on (on full power).
3) Start any heavy game (like Dark Souls 3).
4) When the game loads up, minimize the game, open Task manager.
5) Find the process called on the name of the game (if u are in Windows 10, when you open Task manager, go to Details) (the process is called on the game, for example Dark Souls 3 the process will be called Dark Souls 3 or something similar).
6) Right-click on it and choose set Priority.
7) Choose High and close Task manager.
8) Open again the minimized game and play it for about 30 minutes.
Does the game lag anymore? Please tell me and I will help you?

I'm afraid i don't have a fan like that.But i tried set priority before.It didn't help.

I think this issue is from overheating. Try using Speed Fan, with this program you can control the speed of the fans.

Overheating of which part of the system exactly ? 70 C is ok as i know.

So i looked up my gpu temp.It was around 82 degrees.

Yea, 82 degrees is hit GPU, so if u have fan you can try that out.

You have an FX-8320, but what cooler and motherboard? Stock cooler with a quality motherboard or an aftermarket cooler and a 4+1 phase VRM motherboard? I'd guess you have the latter and the VRM throttles the CPU.

Im using this pc about 2 years and i didn't have any problem before.I played heavy games like MGS 5 . But it just didn't happen.

 

[GhislainG]

Do you know what cooler and motherboard you have?

 

[Ben-Gay]

I will look at it and inform you about this.

Mobo: Gıgabyte GA-970A-D3
Cpu Cooler: Cooler Master Hyper 412s

The CPU should be cool enough, but the VRM most likely has to throttle it to protect itself. The stock cooler does a better job by blowing down on the VRM, but you could also install a small fan to cool them better. Adding heasinks on the mosfets would also help to alleviate the issue. Have you tried to increase the speed of the CPU cooler's fan? That should also help.

You had no problems for 2 years while running the VRM quite hot, but unfortunately they won't last forever being treated that way.

What can i do exactly for VRM problem ? And can speeding fans damage fans ? I dont understand this things very much so please nice to me

 

[GhislainG]

What's more important to you? A CPU that doesn't throttle or fans that may last a bit longer? The only way to prevent throttling is to cool both the CPU and the VRM; an even better solution is to use a motherboard that can properly support that CPU (8+2 phase VRM with a heasink like the Gigabyte GA-970A-UD3P), but it's a bit late. Could you post a screen capture of AMD Overdrive while stress testing the CPU with Prime95 Small FFTs? I'd like to see how low the thermal margins drop and if it happens gradually or all of a sudden. I'm not interested in temperatures because they can't be accurately measured.

A CPU that doesn't throttle for sure.I tried to speed up my cpu fan to max but it didn't help.I will test my system with AMD Overdrive tomorrow morning and post a picture here.

Unfortunately the CPU cooler doesn't blow enough air over the VRM components.

So you are saying i need to change my cooler right ?

 

[GhislainG]

It's up to you. You could add a fan like an Antec SpotCool to blow air on the poor VRM, a top-down type cooler like the stock cooler or the AMD Wraith, add heatsinks on the MOSFETs to improve cooling, etc.

The best solution is a motherboard designed to support that CPU properly. I don't understand why people buy inexpensive motherboards and an 8 core FX processor; they just aren't a good match.
