Hello Everyone,

My Rig:
-AMD FX-8350 Black edition
-Asus GTX 960 2GB
-ASrock Extreme-4 970
Corsair VS550 550 Watt PSU
-(Corsair Vengeance 8GB DDR3 Memory Kit (CMZ8GX3M1A1600C10))
Corsair Vengeance 4GB DDR3
-Total RAM 8+4 = 12GB
-WD Caviar Green 2TG

For the past two years I have been using, However I recently found out that there is been a huge performance issue while playing games like FIFA. There seems to be lag occurs every few seconds on the play while playing it in full resolution.

After googling I found out few software like OCCT, Speccy and CPU-z I ran few test while playing FIFA 17. I found that the lag was happening due to the fluctuations occur between the CPU frequency and the multiplier.

I have changed the power option to high performance still it doesn't make any improvements.

I have attached two image one when the fluctuation occurs http://bit.ly/2rcO9QL another Normal mode Picture http://bit.ly/2s3V6I5.

We can see that the frequency drops from 4Ghz to 1.3Ghz and Multiplier drops from 20x to 7x.

Please help me to fix this issue friends. Thanks in Advance.

The vrms on that board aren't really made for the 8350. They eventually start overheating and slow the CPU down to keep from Killing themselves. To confirm this is the issue take the side panel off and point a fan directly at the capicitors nearest the CPU socket and see if you get longer between lag spikes or of they perhaps go away.(there are no temp sensors on the vrms so this is only way to check them fairly easily)

If that fixes not your only long term fixes are to underclock and undervolt your CPU, or buy a board with better power delivery. (Most fx990 boards)

It might not even be the VRMs, but the CPU itself overheating. I believe those FX chips are not really designed to be running in the mid-70s, and you'll notice that the CPU throttles in that image as soon as it hits 75 degrees. I would try adjusting your CPU fan speeds and maybe your case fan setup to get cooler air feeding in to the CPU cooler.

Also, since you've had this system for a couple years, make sure there isn't dust buildup on the heat sink, and that all your fans are working correctly.

Thanks for replying, Actually the temp at normal use is like from 45-55C I am using Deepcool Gammaxx 300 Tower Type with 3 cooler for my processor. But I found out that the main problem is Clocks multiplier is highlighted as in this image https://tinyurl.com/y6ukulqq Normally for other processor there is constant value. Here is the other image I got from google http://bit.ly/2r3zVSQ

So can you suggest is there any way to make this CPU multiplier value as constant. ?

Thanks for replying, I use to clean the CPU every 3-6 month and last week as this issue keep bugging me I completely removed everything and add new heat sink paste everything was fine from the hardware side. Infact the temp at normal time is as in this pic http://bit.ly/2t3hQ8p only at the time of gaming it raise as the above.

Hi all, Finally I have found the Solution for this issue. Thanks for both who gave me some ideas about what went wrong.

It seems the VRM in this board is heating up like hell. Initially there wasn't any problem when my PC was set up.

It seems by time and years the thermal compound (thermal paste) in the VRM was completely dried out.

I had to reassemble my whole PC from the scratch. I have replaced the thermal compound in the VRM. Also I have turned the two 120MM fans inside the CPU (which was initially exhausting out the hot air) Now I have turned in the fan and started blowing the AIR directly near the VRM chipset.

Now the fluctuating issue is gone. I am so happy to submit the solution.

If any of you guys facing similar kind of issue please follow the above things and give a try.

Thank you So much guys.
