i5-7400 BOTTLENECK!? on idle

[flya00]

Hi, everyone. I've posted a few topics on problems with my PC. Mostly or all GPU related. I've have done further research into the issues I see as I use my PC. In a previous post I mentioned how I thought my GPU was bad because I was getting low FPS. After many different types of tests (3DMark, Task Manager open next to game, UserBenchmark) I now understand that my GPU is fine because in game (Forza Horizon 4) (BTW before topic start all video settings are maxed out with VSync.) FH4 only maxed out at 70% usage and 25% Min and got above average scores in all tests. During the Task Manager test with FH4 open both my CPU and RAM were at 100% and would not even go down by 0.1% at any time. Another problem found is that my PC only has 7GB Usable RAM even though I have 8GB and 3GB is cached while 0.7GB is free during gaming. After doing a MemTest86 and Windows Memory Diagnostic I got no issues and with a CPU stress test my screen flickers often and CPU is at 100% with 70C temps.

My CPU does not have thermal paste though I could go buy some, I have not bought any so far because it has only made about 5-10C difference. After playing FH4 for 15 Mins it froze for 10 Mins and then crashed to desktop for 5 Mins and eventually my PC shut off. With ETS2 DX11 My game crashed to desktop instantly after 5 Min. UserBenchmark test found all % going down by 5-15 going from above expectation to expectation and 3DMark Time Spy Extreme got 15775.

Memory average on desktop, no applications open is 45% and CPU is 15-55% After all these tests and new info I would hope someone could help out with fixing whatever issue I have with my PC, and REMEMBER all feedback is appreciated.

I don't even know where to start. You don't use thermal paste on your CPU? Your Opera web browser eats all of your CPU resource, and you only have 8gb of ram.

I've never heard of someone running a modern processor without thermal paste, why would you assemble a system without it? Your computer crashing and shutting down is it screaming in agony for you to apply thermal paste.

OP may mean that they used the pre-applied paste on the HSF.

The CPU is thermal throttling. Solve this first.

 

Also, the PC might be malware infected, for example with a miner.

I had thermal paste on at first but accidentally removed it when I took fan off to clean out dust. I could buy thermal paste anytime.

Yep looks like your Opera browser is being the host for some malware, no way it should be hogging all your CPU.

Well, I was typing this topic, and had YT and a few other blank tabs open. I had Web browser in there to show how any open application causes this much usage, even something like notepad or paint.

Put thermal paste on your CPU.  You are thermal throttling like mad, which is why your general CPU temps are not excessive.  There are other sensors on die that can trip thermal throttling, but you can never see.

Thermal throttling causing it to downclock to like 800mhz and then anything max outs it.

Slower than that, 800mhz with the cpu turned off 75% of the time due to clock modulation is more like it.  so 200hmz or lower.

Well, ill buy thermal paste today or tommorrow and maybe another case fan cause I only have 1.

In the meanwhile how come when I using like 1 or 2GB ram it says 60-80% and it only say I have 7GB available

Task manager doesnt list everything that uses memory, and if you have the integrated graphics enabled it will consume a chunk of memory.

If I put a DVI to Displayport on my monitor and connect it to GPU then I can stop using iGPU and save memory. Right?

No, you need to disable it in BIOS.

Ya, I did that and got 1GB back. I also clean install Windows and memory usage is now 15% on idle and CPU is 5-10% on idle.
