Question Ryzen 3600 Idle Temp and Core speed Jumping up and down

[allinhandss]

Hi,
I recently build my new PC with Ryzen 3600 and Gigabyte X570 Gaming motherboard.

The issue is at idle it has a temp of around 50C and the clock speeds are constantly jumping up and down, even though there is no load on the CPU. I installed the latest drivers and still the same issues. I have no monitoring software running besides CPU-Z. CPU fan also constantly speeds up and slows down at idle.

Also my ram speed reads at 2400mhz, even though it should be 3200mhz. I don't know if that is related. Thanks

It's a cpu specific thing, not general. A 54w core i3 is going to run very cool, more so in more efficient later generations. A 140w core i7 HEDT is going to run very hot. The current heat monster cpu belongs to the i9 9900k, it can generate well over 200w stock, lock the cores at turbo and its 250w. That's roughly the same as the prior king of heat, the AMD FX 9590. So heat is going to depend on exactly what cpu. Your prior Intel is half what you have now, and all that work will come at a price, even with a more efficient design, namely higher temps at times.

At idle, I expect to see 10-15c. over ambient.
I suspect your cooler is not mounted well.
Possibly, you used too much paste.
Or, more likely, the cooler was not tightened down evenly.
Tighten in a crosswise pattern a little at a time.

How is your case cooling?
Any cooler needs a good supply of fresh air to do it's job.

The cooler is mounted well. I don't think I used to much paste, since on the previous was pre-applied and still had similar temps. Case is Thermaltake v200, it has 4 case fans, so should be ok in that regard.

Any cpu runs hotter with a stock cooler, that is why many intel chips don't come with one and AMD definately doesn't run hotter than intel.

I am with an aftermarket cooler now

Which one?

My bios says F2 version, I see there are F3 bios drivers in the Gigabyte official site. Should I go for it. I know that flashing the Bios can be problematic sometimes

Yes, update BIOS just be careful. follow instructions to a "T" and do it from BIOS not SW.

Disable cool&quite from your Bios will fix the CPU frequency jumping issue, when you updated the Bios it came to default turned On position so disable the "cool&quite" function will fix the issue

I recently came from an Intel CPU (i7) as well, and I was starting to question that decision. Our issue sounds really similar. I was having a problem of my Ryzen 5 2600X running around 40-50C at idle, and it kept cycling through a range of temperatures, jumping up to around 50C, then counting back by about 1 degree per second before jumping back up again. So I was running 10-20C hotter despite also changing from a Cooler Master Hyper 212 Evo ($35) to a Noctua NH-U12S ($60).

But now I'm idling around 31C, and no weird temperature cycling, all from 1 simple change to a Windows Setting. Go to Control Panel --> Hardware and Sound --> Power Options --> Edit Plan Settings --> Change advanced power settings -->(new window) expand Processor Power Management --> expand Maximum Processor State. Change it from 100% to 99%. If it's already below 100%, I guess this isn't the fix for you. You could try lowering the Minimum Processor State to 5%, but I didn't notice a difference.

Let me know if it helped.

I would stay away from BIOS which brings compatibility with Ryzen 3000 as long as you keep 1st gen.

I have tried that before, yes. It helped a little bit. I am around 40-45C when browsing. Do you change those settings when gaming or under heavier load on the CPU?

I just discovered the solution, so I'll have to see if setting it from 99% to 100% gives a performance boost for CPU intensive stuff.

What was your solution ?
And yes setting the Maximum Processor State to 100% should give you the best performance.

Sorry, I worded that poorly. Setting it to 99% was my solution because it fixed the high temps and the constant cycling of temps. I just discovered that, so I'm not sure if I should be switching it up to 100% as needed yet. I guess I will if anything is maxing the CPU while set to 99%.

 

[FandmeFarlig]

Wow, this solution by setting down the powerplan to 99% seemed to work straight away. My voltage dropped from around 1.4 to 1.0! I need some more testing, but it really seems to work well!

Don't know what the consequences might be and I loose any performance somewhere.
