While gaming cpu usage jumps to 100% computer lags, fps drops to 5-20 fps

wakattabro · Aug 31, 2016

Hey, as above I said, while i'm playing higher demanding games like fallout 4,far cry 4,BF1,Evolve etc. I play just fine with high fps everything works, after like 5-10 minute(depends on the game) cpu usage jumps to 100%, my whole computer gets really slow, fps drops down to 5-15 fps for 10 seconds, then works perfectly again, then another 5 minutes and the lag comes back. I checked the temps, while gaming,
CPU: AMD FX8350-60 C
GPU: Nvidia Geforce GTX970 Gaming 1 - 44 C
The highest temperature on my motherboard (Gigabyte GA-970A-D3) was 68 C
8GB Ram

I noticed that the metal shielding on my GPU gets really hot, but the temps seems fine. When I put a huge fan to the case, it works perfectly, so it must be some kind of overheat, but on the HW MONITOR everything seems fine. The Motherboard and the HDD is really old, could they cause this problem? I searched many times online, and others with these kind of problems had the FX8350, or FX 8XXX.

League of legends/MMOs/CSGO/SC2/D2 runs just fine. Only big titles seems to has this kind of problem.

If anyone could help me, I would be really thankful, I'm getting tired of problem.
Thank you very much, If i missed out something, please feel free to ask!

you should check the CPU temperature and frequency while gaming.
Seems like it overheats.

GhislainG · Aug 31, 2016

It looks like the VRM gets too hot and it throttles the CPU to protect itself. That's normal with such a motherboard, but the much better Gigabyte GA-970A-UD3P doesn't have that issue.

Alright, so i tried to monitor it.
IDLE- CPU(value):47 C GPU(V):39 C. 20% CPU usage

Start Game BF1
-45%CPU usage. 56 C .Core speed 4127 MHz, Multiplier x20.5
-GPU:53 C

5min- First lag.
Cpu usage:99-100% last for 20 seconds. Temp:58 C.
Core speed:2800 MHZ Multiplier: x14

GPU:62 C

7min next lag
Cpu: 57C 2800MHz x14 99-100 usage
Gpu:60C

The lag occurse every 2-3 minute after it. lasts for 10-20 sec

8gb ram-> 7,4 G usage while gaming.

HDD- 48-50 C

I hope this helps

well, your CPU is throttling for some reason.
It can be due to power delivery issue like mentioned before, or it simply overheats.
I'd try to:
1. play a game with side panel open
2. check that CPU cooler is clean of dust
3. reset the MB BIOS.

wakattabro · Aug 31, 2016

I always play with the pannel of because of this. I will try to clean the whole case out. Thank you for the answers, do you recommend to switch motherboard?

n0ns3ns3 · Aug 31, 2016

not sure it's a worth investment.
Better to sell the CPU/MB/RAM you have and get something from intel.
Probably will cost you the same as just replacing the MB

wakattabro :

Why don't you monitor the thermal margins with AMD Overdrive? Then you'd know for sure the motherboard is the issue.

wakattabro · Aug 31, 2016

I will try it out, and post the results, thank you! What should I look for in the program?

wakattabro · Aug 31, 2016

Alright so, i checked it out. all cores(0-7) ran at maximum 16.25 C, Average 11 C.
TMPIN0-46 C average.
TMPIN1-63 C average
TMPIN2- 70,59 C average, and 73 C maximum.

GhislainG · Aug 31, 2016

Are the 11°C thermal margins at full load? Ideally they should be 10°C or more at full load and obviously much higher at idle.

wakattabro · Sep 1, 2016

at idle is 26 C.
while gaming 11-13 C.

While playing evolve

GhislainG · Sep 1, 2016

26°C at idle is very low; what cooler and case are you using? Are you applying too much voltage?

Since you already selected a solution, in theory you no longer have the issue.

wakattabro · Sep 1, 2016

The cooler i'm using is Cooler Master Hyper 212 EVO. Should i check how much voltage i'm using? The problem is still there, it was a missclick and now i can't really unsolved it... Thanks for still sticking with me!

GhislainG · Sep 1, 2016

I unselected the solution for you. At full load, how much voltage is applied to the CPU? It's shown as VID in AOD, but you didn't post the screen.

wakattabro · Sep 1, 2016

This is when it's on full load and the lag happens:

This is when it works properly while gaming:

GhislainG · Sep 1, 2016

You can see the thermal margins are fine when the lag happens, but the frequency dropped. The VRM probably is the issue, but I'd like to see what happens when you run Prime95 Small FFTs; do the thermal margins drop below 10°C?

wakattabro · Sep 1, 2016

Alright, so i ran the test. The throttling happened after 1min 30 sec. This temperature was the lowest it could've do.

I noticed that it happened when the thermal margin reached 13-13.8 C. always . Another thing was, when it happened i heard a quiet beep sound from the case, till it reached like 30 plus.

GhislainG · Sep 1, 2016

The CPU doesn't get hot enough to throttle, but I presume the frequency dropped at some point just before the thermal margins started to increase? Using a 212 EVO obviously doesn't help because, unlike the stock cooler (or the AMD Wraith) it doesn't cool the VRM.

wakattabro · Sep 2, 2016

Yeah that's right. Thermal margain reaches 13.2, frequency drops and stays like that until the termal margain reaches 30. So what do you think should be the easiest/cheapest way to fix this problem?

GhislainG · Sep 2, 2016

Replace the motherboard with one that can fully support your CPU without having to throttle it at full load. Why didn't you get the Gigabyte GA-970A-UD3P? Its 8-phase VRM with a heatsink makes it appropriate for your CPU. Your motherboard doesn't support any 125W FX CPU simply because the VRM isn't up to the task.

wakattabro · Sep 5, 2016

Well, i have this motherboard for like 4-5 years now. Thank you for the help, I think I will go with the motherboard you said if that's the best option. Thank you for your helps again!

GhislainG · Sep 5, 2016

It probably is the best Gigabyte motherboard if your budget is limited. There are better motherboards based on the 990FX chipset, but they also cost more. If you don't mind switching to Asus, then you should seriously consider is the new Asus 970 PRO GAMING/AURA (that would be my choice if I had to buy a motherboard for a FX-8350).

While gaming cpu usage jumps to 100% computer lags, fps drops to 5-20 fps
