AMD Ryzen temp spikes. How and why?

Hey guys,

OS: Microsoft Windows 10 Home
Motherboard: Gigabyte A320M-DS2
Processor: AMD Ryzen 5 1600X Six-Core Processor, 3600 ( Not overclocked)
Installed Physical Memory (RAM): 8.00 GB 2400
Gfx: 750ti
AIO: Corsair H55

I just came from a recent upgrade from my old rig.

I was was wondering why Ryzen chips spike exactly 10c every few seconds. It only surfaced when I downloaded the new drivers and used the Ryzen Balanced power plan.
I know its due to XFR but its just too damn consistent to be based on usage, like every 5-8 seconds consistent.

I checked other threads and the answers are all over the place. One thread said it was the Bluetooth is turned on. Another thread said it was due to Ryzen Master, advised to check temps with it off (it's still the same 10c spike). My friend's Intel chip never did that even with turbo boost on.

Thing is, I noticed it stops doing it whenever I change anything within the Ryzen Balanced power plan. If I change the min and or the max processor state to Like this either min 89 or max 99 or any other value less than the default it provided.

Should I leave it to the default of min 90% max 100%? Or do I lose something if I change whatever AMD put in place?

*Edit* it's just when the max power that does this... well don't know what I can't seem to strike my own text its all underlining it T_T

OK...I tried some of the different power plans and found the Low Power plan does what I want... sort of.

I suspect the reason it's popping up in temp is because of background tasks that are (almost) always rummaging around in a Win10 system and the aggressive nature of Ryzen Balanced lets the processor 'boost' speed quickly for them with the accompanying temp spike to rev up cooling in case the load is sustained. Even default Balanced plan lets it boost 4 cores and that's enough to spike temps (the other 4 remain parked). But Low power plan doesn't boost so aggressively and therefore it's not spiking temps until a truely demanding task comes along.

All the Ryzen Balanced plan seems to do is let all cores (8 in my case) boost...


[strike]I don't have an answer as to why it does this but I did want to thank you for the tip on stopping it. I adjusted the Ryzen Balanced Processor power plan to 99% max and 39% max and it seems to have stopped the spikes. They were really annoying as I have my radiator fan profile set on steps so it would 'pulse' the fans at a moderate processor load when they'd push temp only briefly above a threshold every few seconds.

I also note that it seems to affect VCore and Core Frequency averages: they are lower over a period of time of low/moderate use-age such as browsing and document editing in Office. I am monitoring using HWInfo64.

If this doesn't 'hold' i'll uninstall RyzenMaster and see if that does. I'm not sure why uninstalling it would do anything unless it also uninstalls the Ryzen Balanced power plan.
[/strike]

EDIT - UPDATE: Forget all this: dropping power plan max to 99% means the processor never operates below Power State P1, therefore never at max processor speed. So that limits it to 2.7G (in my case) and that's certainly why average frequency is lower and doubtless why voltage and temps never spike either. I uninstalled RyzenMaster...use MS Balanced and even High Perf power plan and it still gives spikes. I guess I'll fuss with fan profiles so they don't pulse under common useage.
Thanks again.

All the Ryzen Balanced plan seems to do is let all cores (8 in my case) boost with every little background task that comes along but no more agressively than default Balanced. I think this is good for benchmarks, especially in games, as that's why it was created.

In everyday useage (OS navigating, browsing, document editing) it seems to be just as responsive but I'll see how it reacts as I play some games next. I'm sure a sustained heavy load such as a video encoding will result in all cores boosting to full speed. Any delay imposed by the low-power plan will be unnoticeable except in a benchmark.

That makes sense, I've experimented trying to mimic the ryzen setting plan with the CPU core parking tool and unparked all my cores using the normal balanced plan it never really did that 10c spike even with 90 min 100 max.

I suggest just using the CPU parking tool to just unpark all cores and use any power plan you want unless the Ryzen Balanced plan is doing something else we don't know about. I'm just guessing it's super aggressive enough that mouse movements and other normal tasks make it think it needs a boost aggressive enough to spike that 10c and use 1.45v of the processor.

I don't know if that's a good enough trade-off for me since I'm a bit paranoid and really want to know everything that's going on with that plan.
 
I just upgraded to 2950X aswell and having the same issues. after reading this is was testing stuff in the power management and found out that using power saver mode actualy helped alot. the CPU doesnt boost as agressive as the Ryzen mode does so it keeps the CPU cold and not boosting. been testing with CPU Z and by going from ryzen mode to power saver i went from 9600 score to 9300. so just 300 points for a ALOT more silent running system.
Hope it helps =)
