CPU Temperature being "bottlenecked" when playing a game

Rutvik123 · Jul 10, 2016

I recently built my computer about a month ago. When building, I did run into a DOA Ram stick and had to get a new one. After that, since today, everything was smooth and fine. My PC Specs are:

CPU: Amd fx-6300
GPU: Gtx 960 SSC
Mobo: GA-970A-DS3P
RAM: 8 gb Crucial Ballistix
HDD: 2 tb Seagate
Cooler: Hyper T4 by Cooler Master

Before i ran into this problem i ran Minecraft all high settings at around 200-300 fps and Team Fortress 2 at 300 fps locked. About 3 days back i noticed a little dip in the fps i thought it was weird so i restart and its all fine. and Since yesterday my PC has been really weird. TF 2 is running at 30-60 at all low settings, same with Minecraft. When i check my CPU temperatures using Core Temp it is merely 20 degrees Celsius. Before the problem occured my cpu used to hover around 30-40 on load and 20 on idle..... So i decided to run a stress test, all my thermal margins and temperatures are just right. I decide to overclock my cpu, from 3.5 to 4 ghz, that did help a little but still no success, Whenever i start playing a game, the cpu temperatures boost up to 30 (which is the temperature i am supposed to be averaging) and give me great fps but then after about 3 seconds the temperature drops to 20 and refuses to go up... The temperature seems to be getting "bottlenecked" when i play a game, help anyone?

You are using Core Temp to monitor temps? Core Temp cannot be trusted, it told me that my FX-8350 was running at 12384MHz (which is above the world record set using liquid hydrogen).

Please get rid of Core Temp.

Please download Hardware Info to monitor temperatures.

I kinda feel like I doubt your CPU temps would be 30-40c load running on a mediocre air-cooler. Try using another temp monitoring software a lot of people recommend Hardware Info, I like NZXT Cam try one of those!

I was actually thinking of asking the moderators to put together a post on what the best utilities are for determining the specifics of your hardware (like clock speeds and temperature)... Would you like to see that done?

weberdarren97 :

I have tested my temperatures with many programs, they all say the same thing, i even downloaded AMD Overdrive and the thermal margins matched the temperatures.

Here are some screen shots i was on minecraft and my CPU temp was where it used to be before, 30-40

Here is a screen shot after loading into MC and leaving it for a minute of 2

And the same thing happening with tf2

I used HWMonitor and put as much load as i could on my game to have its temperatures rev up.... but the temperature does not want to move from 20... i don know whats causing this...

I don't understand why it's showing the package temp and not the core temps...

weberdarren97 :

Do you know how i can change it? i cant figure it out :/

weberdarren97 · Jul 10, 2016

It's not a setting that can be changed. It's that the CPU is not reporting it's core temperatures.

I will message a few more knowledgeable users, please wait for their responses.

First things first: upgrade to windows 10. This will make sure that about half of the issues taht may cause this are off the list.

Ecky · Jul 10, 2016

Have you checked whether vertical sync is forced or enabled in both drivers, and in the games themselves?

Rutvik123 · Jul 10, 2016

Ecky :

Yes, i have even created a debug profiles for my games

Rutvik123 · Jul 10, 2016

Hlsgsz :

Will do, reply back when i am done

Rutvik123 · Jul 11, 2016

Before upgrading to windows i wanted to make sure what was happening, and here is what has been happening. When i play a game, my cpu clock speed is at 3.8 ghz but soon after the cpu seems to declock itself and i get low fps. When i start off a game the cpu speed is fine but then the speed flucuates from 1.32 to 2.2 ghz for a minute and then sets it clock speed to 1.32 ghz (the speed when the pc is idle)...

Here are some screen shots, its like my cpu is thinking that i am not playing a game or doing anything because when i am running stress tests my cpu seems to be fine and not throttle, it goes all the way up to 4.0 Ghz and stays there. It is only when i am playing games.

Here are some screen shots:

Looks like you CPU is getting throttled. Either the MB is not able to feed it the current it needs due to poor VRM design, or the PSU is acting up. Seeing as you said you were able to run just fien for a while, my money's on the PSU. What make/model is it?

Rutvik123 · Jul 11, 2016

Hlsgsz :

My PSU is a EVGA 500W 80+ Silver

Hlsgsz · Jul 11, 2016

Yup it could be the PSU. Can you borrow another and test with it.
I woudl still upgrade windows just to cross Win off of teh potential list of culprits.
