Is my 3600 broken?

Mainboard: MSI b450 gaming plus max, last bios
CPU: Ryzen 3600
RAM: hyper x dimm fury 3200 8x2 (in compatibility list, passed memtest)
Drive: cheap M.2 crucial (os) + seagate hard drive
Graphics: msi 1660 super
PSU: be quiet pure power 11 500w gold
OS: Win 10 Pro 64 updated
Chipset driver: 2.13.27.501 (last?)

So, this was my sad story of crash and reboots:

https://community.amd.com/t5/processors/ryzen-3600-mostly-reboots-and-some-crash/td-p/422417/highlig...

My ryzen is unstable under the stock normal settings, i often get reboots/crash loops until voltage get stuck at 1.4 on last core for some reason, i have no clue about this and no one was able to explain.

All my reboots/crash are at low use.

I believed to have found some solution from here, setting the multiplier at 36, that disabled all the boosting, voltage got at a chill 1.2-1.1 and then 5 good months of perfect stability.

Until last week, when reboots came back, here a dump from WhoCrashed:

On Tue 30/03/2021 18:16:19 your computer crashed or a problem was reported
crash dump file: C:\Windows\LiveKernelReports\WHEA\WHEA-20210330-1816.dmp
This was probably caused by the following module: ntoskrnl.exe (nt+0x97E766)
Bugcheck code: 0x124 (0x0, 0xFFFFD60504F4E840, 0xBEA00000, 0x108)
Error: WHEA_UNCORRECTABLE_ERROR
file path: C:\Windows\system32\ntoskrnl.exe
product: Microsoft® Windows® Operating System
company: Microsoft Corporation
description: NT Kernel & System
Bug check description: This bug check indicates that a fatal hardware error has occurred. This bug check uses the error data that is provided by the Windows Hardware Error Architecture (WHEA).
This is likely to be caused by a hardware problem.
The crash took place in the Windows kernel. Possibly this problem is caused by another driver that cannot be identified at this time.

The current ones are always the same, clean reboot, no blue screen, windows integrity ok.

I updated everything again, updated windows/chipset/bios, tried again at bios stock settings and reboot right away.

I have now disabled the precision boost overdrive. (it was always auto), so no more boosting over 3600.
The pc seems stable (for today), did some occt tests for power and cpu, voltage is even lower than under multiplier 36, got max 1.08 on vid single core, 1.1 on tfn and 1.125 vid effective from HWiNFO64.

I dunno, got the cpu on october 5, i have more or less still a year and half of warranty.

Now, what to do? And is cpu truly the problem here?

Re: Is my 3600 broken?

Again reboot after a week, under stock setting, core performance boost and precision boost overdrive disabled.

So, i shorted the mobo, factory stock now, and the pc is working with he boosting on, multiplier rise to 42 , i never had this stability, i don't get it.
Even before when i had some days of working with boosting (last year) i still had some cpu error when restarting/turning off the pc, now is clean.

i don't get it, i don't even know what my problem is anymore now.

Re: Is my 3600 broken?

So you are saying that after doing a CMOS CLEAR and resetting BIOS to it factory settings, your Ryzen is now working fine?

Most likely it could have been a BIOS setting you had set causing part of your problem or it could have been if you updated the AMD Driver which may have fixed your issue.

I would install Ryzen Master and see what it indicates. If you see anything in yellow or red.

Maybe if your update the motherboard's BIOS and Chipset driver might help with stability. Many times a new BIOS indicates it is for better system compatibility or stability.

Re: Is my 3600 broken?

Ryzen is working fine "today" but as i said i had weeks of perfect stabilty before.
I was unable to get the boosting on with the current newer bios and the update before, i also did not changed any settings but the ram freq, the core ratio or boosting disable.

I dunno.

I'm not gonna put ryzen master back on, look at my old topic: https://community.amd.com/t5/processors/ryzen-3600-mostly-reboots-and-some-crash/td-p/422417/page/5

Maybe you can explain me why ryzen master did that thing to the core number 6, plus the many settings change (to what?) after the reboots?

Anyway, i noticed that in the mobo psu cable (20+4 pin) the +4 pin was a bit loose, fixed it.
Can this be the cause of my WHEA_UNCORRECTABLE_ERROR?

Re: Is my 3600 broken?

Most definitely could cause your issue if the main 24 Pin Motherboard connection was loose or wasn't completely in.

Re: Is my 3600 broken?

So having a loose +4 of the 20+4 pin cable can cause clean random reboots every few weeks at time?
Man, i feel so stupid, i had so many troubles and tried alot of things.

Well, do i keep the bios at factory stock (except ram thing) and see how it goes?

Anyway, i got a second psu (a old AeroCool VP-650) to test with.

Re: Is my 3600 broken?

The Motherboard 24 pin plug is the Main connector. If it isn't making good contact in all 24 pins it can cause all sort of problems including not booting up

In my BIOS at first I did have everything factory set except like you, the RAM which I overclock to get the RAM's recommended speed.

Later I slowly started change a couple of settings one of which was disabling Fast Start which I didn't realize was enabled by default.

Re: Is my 3600 broken?

If you mean the fast start option in windows power settings, i have it disabled.

Some other improvements?

No, BIOS also has a setting for Fast Start. That is the one you need to disable if it is enabled.

For some reason that Bios setting causes many issues on User's computers.

Re: Is my 3600 broken?

I can't find the fast boot option in the bios.

Nothing in boot, on google found this:

But i only have the windows 10 csm option?

Anyway pc need something like... 20 seconds to get to desktop. (i don't have many extra programs and i also disabled some windows ones)
Booting from m2 and keyboard is working during boot. (i press f11 to get in bios)

I suppose i don't have it or is disabled?
