CPU Usage dropping randomly causing Frame drops - AMD FX 8350 (Black Edition)

So recently I've been noticing since putting in some new RAM that I get sudden frame drops while playing games like Call Of Duty: World War II, Final Fantasy XIV, Just Cause 3, PlayerUnk and other games as well. Frames dropping from around 80-120FPS down to 30FPS and sometimes even as low as 10-15FPS for what the most part, seems like no reason at all. This happens quite frequently during a session with it occurring once or twice within a minute and each time, lasting 5-10 seconds. Now before I used to only have occasional quick freezes due to not having enough memory but they would only be for a split second.

Here's a list of all of my PC specs

Motherboard: Asus M5A78L-M/USB3

CPU: AMD FX(tm)-8350 Eight-Core Processor (8 CPUs), ~4.0GHz

RAM: 32GB 4x8GB Corsair CMY16GX3M2A1600C9R Vengeance DDR3

Previous RAM: 8GB 2x4GB Elite+ TPKD34G1600HC11BK DDR3

HDD: 1TB Hard Drive

SSD: 500GB Samsung 750 EVO

GPU: NVIDIA GeForce GTX 1060

Here's what it does -

For this I just sat on top of this building here on Just Cause 3 and did nothing, Before this I was getting 95-100FPS then when the drop happened I took a screenshot of my entire screen with Task Manager on the other monitor and brought it in the screenshot. As shown the usage drops down to 30% and will stay like this for a few seconds and will be stable. Also my speed drops down to 1.3GHz and then will resume back up to 4.02GHz.

I've noticed a couple of people having these issues as well but not found an answer to fix this. Was hoping if we can make this post an answer for the people searching for it.

Your CPU utilization is almost at 100% in that screenshot, so you need to find out whatever is causing the high utilization. That will most likely lead you to the solution.

It's happening on other games and such where it's 60-70% usage. Just Cause 3 is quite intensive at least for my CPU as the video I linked shows it was on 66% before it even dropped

Re: CPU Usage dropping randomly causing Frame drops - AMD FX 8350 (Black Edition)

I'm having very similar issues with my FX 9590. When I try to play any game the FPS drops High to Low. Example being: COD:WII FPS Is 100 drops to 30 for a few seconds then goes back to 100 and does this every few seconds. I noticed that the CPU's Speed is going from 4.7 to 1.3 and again back to 4.7 every few seconds. Anyone help?

Interesting.

I am going to take a stab in the dark here based on my knowledge of using FX CPUs and helping customers on this forum. This applies to both of you, are your Motherboard VRMs overheating? HWINFO64 should be able to tell you.

Okay so I've installed HWINFO64. Where would I go to check for if the VRM's are overheating?

Play Just Cause for 30 minutes, then post a screenshot of HWINFO showing the CPU/Motherbaord temps.

Computer power plan set to 'high performance? (not set to the default 'balanced')

Power limit setting:

AMD graphics performance

RX480 FPS drop in all games

What CPU cooler are you using?

Is your CPU running at stock clocks?

Correct me if i am wrong, but is this your Motherboard?

If so, it has no heatsinks on the VRMS, which will be a problem.

82C is too high.
