Question CPU sometimes stuck on 0.90 GGz or 1.98 GGz (and generally works slower)

[egorka13]

Hey everyone! I'm just desperate at this point. A bit of specs before describing the problem:
Laptop: Samsung np355v4c. (amd a10 4600m)
AMD Radeon HD 7670M / AMD Radeon HD 7660G
I have a SSD for 8 months, works great. 12GB of RAM.
I changed thermopaste a year ago and for the last 2-3 weeks laptop got significantly slower. I changed it again and saw that the old one was still fresh.
So I open Cubase and CPU goes to 20% which is impossible to work with. If i try to watch some movie and use Chrome - the movie lags and Chrome works very slow.
I tried to uninstall drivers and install them again (btw laptop overheats when it runs without drivers by it's own videocard or something, so gotta install AMD drivers on the cold balcony). Deleted Web Companion.
https://ibb.co/X58BR9Y - and when i try to check my system with antivirus CPU works like this. It's very often just goes to 39% and stays there.
I disabled Fast Startup in the power options, turned on the most powerful setting of power option (min-max CPU = 100%, cooling - active). I've read that this whole thing is called Underclocking, but how do I fix this... I used to play this game http://krunker.io/ and it used to work great, now it's like 5FPS. Even spotify is lagging.

When you look in device manager what is listed as your display adapter?

Did you check that your cooling is still working? Down-clocking could be a symptom of failing cooling. Dis you check temperatures with a tool like CPU-Z or HWInfo?

those are listed. AMD offers one-file installer (and auto-detecter) for them. And i did install, reinstall both of the versions (Catalyst Software Suite and Radeon Software Crimson Edition Beta) separately.

I checked with AIDA, here are the results while running Krunker.io in chrome which lags really bad. I can hear the fan spinning and when I'm launching laptop with its basic videocard - it works really loud.

Mh, okay, that doesn't look too bad especially for a notebook. Then I'm not sure. Windows Power Plan? If it's set ro energy saving somehow, that could be it. Don't know if you checked that already. It's a kinda weird issue tbh.

Yep, it's on the High Power thing or something (don't know how it's called in English). Min-Max CPU are on 100%, cooling - active (not passive). How does the voltage look to you? Should i try a different power cord? Or it's unlikely that it could solve the problem?

Well, I don't really know what normal voltage for this CPU looks like. Laptops aren't really my specialty. But it is in a range that I would consider normal based on my own processors. If you can try out a different power cord, do it, but I really can't tell you if it would help or not, I'm sorry.

Run this benchmark and post the results please. Home - UserBenchmark

 

[Fix_that_Glitch]

Sorry, when you run the benchmark make sure all background or open programs are all closed, please.

Everything was closed during the test. I'm starting to think maybe the fan is faulty, haven't changed it since June 2018. I can hear it spinning often.
I also tried different power cord today - didn't help.

Try this see if it boosts your cpu.....Press the blue Fn key...then press the Function key that has the Fan symbol on it . ( Maybe f11)

I don't see anything doing that, and nothing changes. Though my Fn keys work for volume changing and i checked it on the other website.

I just tried this

Launched this stress.bat file 3 times, i hear the fan, but it doesn't work hard. And i have this exact CPU picture again -https://imgbb.com/X58BR9Y
I was reading this thread and thought that it all seems very familiar

Question - Laptop CPU stuck at 0.4 GHz

I've got a problem with my Swift 3 laptop and I've spent a couple of hours searching for a solution, to no avail. I have a Swift SF314-41 (N17W7) which has a Ryzen 3500U CPU. The problem started yesterday without any obvious changes (no Windows updates, no damage, no new software, etc) and is...

forums.tomsguide.com

Same laptop, same CPU, same issue. Turns out, it was the fan. It got stuck on something, and stopped spinning, the laptop detected that and throttled the CPU.
Managed to get the foreign object out of my fan vents and everything went back to normal immediatly.
But i can hear my fan all the time, maybe it's working hard and trying to overcome some trouble inside it? Or I wouldn't hear it at all if it was faulty?

One more thing if that helps - I did full Kaspersky scan - nothing found.

Hey,

I recently had a similar issue with a laptop - not sure if this will work for you, but it was the battery in my case and once I removed it, the performance went back to normal.

The battery was not holding charge, but it was being detected and no warning was popping up - I just removed it and restarted.

I would assume that Windows was treating the battery as bad and reduced performance to reduce the heat and stress on the system, hence completely killing the performance.

If you can test without battery just on cord to see if it will make a difference.

Good luck

Thanks for your contribution! I forgot to write in my post that i never used a battery since 2014, it died.

And now when just using Chrome i get this and everything works sooo slow.

Went to a service center, they changed the thermopaste, cleaned the laptop from dust and put some more pressure to the cooling tubes. The situation improved a bit, but the same exact problem with dropping and staying at exactly 1.79 or 0.90 GHZ is still there.
Tried to play a heavy project in Cubase that worked well in January - I got constant 100% - 39% drops.

 

[egorka13]

Any idea why when idling it shows 5% Cpu usage, but around 2.5-3.0 Ghz?
