Severe clock speed drops on Ryzen 3800x to 0.5GHz at idle

Hi all, first time posting anything like this

 

I built my PC around 6 months ago, and so far it's been great, whilst I haven't touched overclocking at all with regards to the CPU it has been fast enough for anything I'm using it for, so I haven't bothered.

Today however, I've been having some very bizarre issues. Even when sitting at idle, my clock speeds have been randomly dropping from the around 4.3 that it tends to sit at with its own boosting settings (that I haven't touched) to a minimum of 0.5GHz, for completely no reason, even when the load is only at around 5%

 

It will then for no reason at all come back up to the expected clock speeds completely randomly, the biggest way I noticed this was the severe frame drops I was having every few seconds when gaming, but once I looked in task manager I saw the speed was so severely limited.

 

I've downloaded Ryzen Master to see if I could spot anything, but the pump on my aio is working totally normally, the maximum temp my package has seen since restart (with no gaming) is around 60, and it is often dropping to as low as 37 degrees when the clock speed plummets.

 

The most bizarre thing I noticed by change was the 'TDC' and EDC' of the cpu, (which apparently are sustained and peak current limit of the cpu) shown in the advanced section of Ryzen Master, seem to show a reading of sometimes almost 250% whenever I have a clock speed drop.

 

If anyone has experienced this or knows what it could be related to, any help would be greatly appreciated... I've emailed AMD, but who knows how long that might take, so I was hoping I might find some additional suggestions from some of the geniuses on here

I've attached some pics (sorry I had to grab them with my phone, i'm aware the quality is awful) to show what I mean with regards to the high current draw, but right now it is really preventing me from doing anything useful with my system, as it's even struggling to move tabs around when it has a 'moment'

 

TIA 🙂

What Power Plan are you using / setting to under Windows?

If you are using the "regular" Balanced or Power Saver, it will drop the CPU frequency during idle / low loads.

You are seeing it jump around because background task(s) / process(es) is making it at least one of the CPU cores / threads work.

You should be using the 'AMD Ryzen Balanced' profile (only comes up if you have your motherboard chipset drivers installed).

If you want your CPU frequency to stay at max the whole time instead of dropping down (which is normal in stock scenarios) you either have to fiddle with windows power manager and set it to max performance or lock the frequency in place in bios, whichever works for you.

 

I don't have enough knowledge to assist you further, having only really overclocked one ryzen system up to now - but it's possible to do. Youtube will help you, I'm sure.

It's been on Ryzen High Performance since I've had windows installed, I'm not sure this is something I've ever gone near. Obviously I'd be expecting the speed to vary to a degree, but I've had task manager and HWMonitor open for extended periods of time before and I've never seen it drop significantly, especially not into the MHz range. Even if it was to drop, the confusing thing to me is why it would be randomly when I'm running programs, for example I had a few chrome tabs open earlier, along with watching a football match, and it was barely registering me trying to drag windows around, and took a good 5 seconds+ after pressing CTL+ALT+DLT to get any system reponse.

 

In the process of writing this, I reset the min/max values on hwmonitor, and at the point of writing now the min value has again gone down to 546MHz, even when the normal value tends to be 3.6-4.4ish...

 

I can always give Ryzen balanced a shot instead of Ryzen HP power mode, but it's leaving me baffled as to why this is a problem thats only just started occuring

 

ALSO, not sure if thats a particularly large number for the Amps being drawn, but the current as shown in one of the images maxes out at 219A, this just seems a bit suspicious to me when Ryzen master itself says the peak current limit is 140 amps as its current 100% value...

 

Thanks for your input! 🙂

Yeah, in normal situations both of these are settings I wouldn't tend to fiddle with, as this rig is powerful enough for me to not need to overclock, it's just the fact that as of today, even after multiple retarts and leaving it off for a good amount of time, the current draw seems to be so high, and the clock speed seems to be dropping so low, even when I'm actively trying to use the machine, rather than it just sitting there totally idle

Thanks tho 🙂

EDIT: Ive had it off overnight and I've just started it up again, and on HWmonitor the highest power draw I'm seeing is 186W. I don't know much about these Ryzen chips with regards to what their expected power draw is, but to me that seems really high when all I have open is a pdf, chrome, and CPU usage isnt above 8% at any power, yet the power draw is still constantly fluctuating and spiking that high?
