[SOLVED] Ryzen 5 2600 overheating and running constantly at 3.4 for no reason

[Jan_JK]

I won't go into full specs, most importantly I have ryzen 5 2600 and msi b450 a pro motherboard. I have not yet flashed new bios, although current one supports this ryzen cpu, its post march version.

So generally cpu overheats constantly, temperatures hover around 80-100 degrees. Its clock appears to be stuck at around 3.4 ghz for no particular reason, in bios as well as in windows. Cooler definitely works fine. Due to these facts, the pc shuts down randomly under additional stress, like in games. Changing to default bios settings doesn't seem to solve the issue.

Has anyone had problem like this before? Do you think flashing new bios could resolve the issue?

EDIT: Have in mind that everything was fine for a long time, this problem occured randomly recently.

Cooler definitely isn't working fine if the CPU is overheating.

Try to remount the cooler with new thermal paste.

Either A- the cpu cooler is not running fine(poor connection, too much or not enough thermal grease)
B- you have poor airflow in the case
C- Motherboard has the voltage set too high
D- all of the above
What cpu cooler are you using? What case and fans are you using and how are the fans setup?

Need all the info specs, case, psu........everything

indeed cpu shouldn't overheat and I plan on changing the cooler as it's pretty weak
what's really the issue is that in such temperature, the cpu should at least throttle, but it stays at max frequency for no reason and keeps heating up

A - cpu cooler is fine, it's the stock one that comes in the box, I checked the rpm and it's fairly high
B - bad airflow doesn't justify constant 3.4 ghz and 100 degrees
C - checked the voltage, it's around 1.5 but most importantly it fluctuates and it's set on auto, it could be motherboards bug which.. should be resolved by flashing new bios at least, we'll see. But it definitely is connected with cpu stuck at highest frequency.
D - probably in some part, I just hope it's not broken CPU or motherboard

Can't really get you a screenshot of anything right now ^^"
but it's ryzen 5 2600 3.4 ghz, msi b450 a pro, 8gbs of I believe 2133 corsair vengeance
although I have absolutely no idea how that could help

3.4ghz isn't the max frequency. In fact, 3.4ghz is the base clock, meaning the CPU is not turboing due to thermals. From my experience the CPU will run at 3.9ghz with 1 core stressed and 3.7/3.8 with multiple cores stressed.

The stock cooler should be enough if your not overclocked. It may not be mounted correctly. Simply taking it off and remounting it may fix the issue.

Try setting a manual voltage in your bios. 1.3v should do it, but it may need to be raised for stability.

"B - bad airflow doesn't justify constant 3.4 ghz and 100 degrees "

It most certainly does...airflow is critical...you can't put a hot cpu in a tight box and expect everything to be ok.

The other guys are right. Full specs please.

That cpu should be able to go to close to 4ghz, so it sounds like your CPU is holding back trying to not fry itself.

The amount of fans and cooling in your case DOES make a difference. If you think they don't then you don't know what your talking about. The more air you are moving through the case, the more cool air the CPU cooler can pull in due to lower ambient temps.

As was stated, try to set manual voltage on your motherboard. My 1700x for example is overclocked to 3.8ghz and will run all day at 1,325. Max of 66 usually under 100% loads. Though I've seen lower. But I do have 6 120mm fans moving air through my case.

everyone is offering help and OP already knows it all

 

[ohio_buckeye]

Yeah kind of picked up those vibes.

A- I'm going to guess you think the cpu cooler is fine because the fan is spinning. Just because the fan spins does not mean the cooler has good contact with the cpu.
B- Yes, Yes it does. Air flow is what moves cool air into the case and hot air out. If that's not happening you will have thermal problems. Hence why I asked about the case and fan setup.
C- 1.5v is high you need to turn that down.

Op will probably be back with their CPU fried in a week or so.

Till like, friday I simply won't have time to try and remount the cooler or try changing the position of case fans.
With cpu at 100° I don't use the pc at all until I solve the issue.
Now that I thought this through I am starting to believe that cooler could come lose. I remember having problems with mounting it in first place a few months back..
Thanks for all the help, I definitely appreciate it.
I will try everything I can, but not until a few days 😂.
In terms of general airflow, I still really doubt that it could bump up temperatures that high. That said I have like one fan pulling cold air from the front and one at the back pushing hot air outside. No worries.

This is a stock cooler, but my 1700x didn't come with a cooler, and I bought one of these a while back.

Works great on my 1700x. Even overclocked it only gets up to 66 under full load. Got a 3600 coming though, so that is what I'll be using again. But you could always look at something like a hyper 212 evo or other aftermarket cooler. Those would probably drop your temps. Also, maybe check and see if your board has any bios updates available that affect your CPU. It may be that they fixed some things with more recent updates.

Additionally to cooler being loose and the thermal paste basically burned, I found that in windows power management settings, the minimal power for cpu was 90%, that was making it clock constantly at 3.4ghz. I changed it back to 5% and now everything works perfectly.
