Great processor but when I'm just doing menial stuff like browsing and just being on the desktop it's causing my PC to randomly restart. I have a 850w PSU and this never happened to me before I replace my older 3900x. Looking at this on google it seems to be a prevalent problem and I have tried everything under the sun.

Is this a DUD chip and should I send it back to AMD to replace it? It's getting ridiculous!

Welcome to ryzen 5000, this crap has been happening since ryzen 5000 launched. Only thing I can suggest is to update the bios, then reset the bios settings to default, don't change anything and then test to see if it crashes.

If it crashes then it's most likely to be: dud CPU or CPU incompatible with motherboard and/or ram
 
Have you tried enabling the power supply idle control setting in BIOS, some PSU aren't coping with the low load of this chip and setting this allows it to use more power at idle.
 
I was having these on a 3700x after a BIOS update. You might have a different BIOS layout, mine is an ASUS strix rog x570 whatever. No problems full draw gaming, but when idling on desktop or browsing web, would get random black out and restart. Windows event viewer showed a power critical error. Deffo not my PSU so went and did some digging in the BIOS after reading similar stories elsewhere.

in BIOS > ADVANCED TAB >

1. POWER STATE IDLE CONTROL > change to TYPICAL

this first step will fix it most likely. The cpu idles so low that the computer just turns itself off. If it doesn't work try step 2.

2. AMD CBS > NBIO COMMON OPTIONS > SMU COMMON > DF CSTATES, changed from ENABLED TO DISABLED.

This has stopped all my crashes. I believe it is something to do with the CPU putting certain cores to sleep, windows detecting this and just turning the power off. Anyway, all sorted and didn't cost me a penny.

That's interesting, i know this can happen when you set the negative curve optimiser too high, it would pass every stress test with flying colours but the PC would randomly shut off when its in an idle state.

I just looked at my cores power consumption when idle and the cores are idling as low as 0.023 Watts, that's impossibly low, that is like a mobile phone chip at idle and here's the thing, Windows Mobile has a much higher idle power state than Android or iOS because Microsofts OS cannot handle very low power states. its can't deal with tiny fractions of a Watt power states.

I find that fascinating.

This is exactly what I am experiencing. No crashes so far whilst gaming which is absolutely bizarre.

I will try this setting later and hope for the best.

For reference I have an MSI B550 MPG Gaming ITX motherboard with the latest non-beta BIOS

That is bizarre indeed. Basically we should have called out Microsoft during the COP23 because that higher idle state would probably translate to a gigawatt of energy wasted per year worldwide or something like that :D

That is pretty fascinating, nice one.
 
I just want to confirm that
1. POWER STATE IDLE CONTROL > change to TYPICAL
did the trick and no more restarts whilst idling/browsing/low workload work on Windows
 
That's why using mobos designed for the cpu generation is best.

x570 was designed for ryzen 3000

amd changed how power management works on ryzen 5000 which creates issues in some instances on x570/b550

But x570 and b550 are the last chipsets for AM4?

I know, I'm just commenting that AMD actually made a serious change to the way power management works on Ryzen 5000 and then shoehorned the chips into chipsets and boards that were not originally designed for it via bios updates instead of just releasing a new chipset and boards. And it works fine for most people, don't get me wrong, it just could have been smoother

ah yes, I was wondering if there were any new ones coming out but looks like we're stuck with half arsed chipsets.
 
Power supply idle control mitigates issues with old/cheap PSUs attached to motherboard it is not a chipset or 5k issue or at least it comes under psu section in AMD troubleshooting.
 
I wouldn't call my month old V850 SFX PSU old or cheap.

Nor the other PSU I replaced it with (Seasonic GX 850 Gold) when I started having the restart issues.
 
I just want to update this thread in case someone with the same problem comes accross it.

I thought I managed to make the CPU stable with the above solutions but all I did was make it last longer before it randomly restarts from a few hours to a day or two.

So in the end I RMA'd it back to AMD (it went all the way to the Netherlands) and got a new one. Been running this new CPU since Christmas and all my problems disappeared. I tried default BIOS settings, previous settings, let it idle for a day with minimal background items running... rock solid stable. I'm also getting much better temperatures and better IF clocks. This is the first time I've ever had a dud CPU and AMD's RMA process was swift and really good. Kudos AMD.

Glad you got it sorted. I wonder how widespread this issue is, what's the RMA % etc.

Also, wonder if the reliability will improve once AMD swaps to a LGA type socket.
