Hi all,

Really hoping someone can help me. I built myself a new PC system July last year as follows:

  • MSI MAG X570 TOMAHAWK WIFI X570 ATX Motherboard
  • 2TB Corsair Force MP600, M.2
  • 850W Seasonic PRIME PX 80 PLUS Platinum (replaced with 850W Seasonic Focus PX-850 80PLUS Platinum)
  • Team Group 8Pack Edition 32GB (2x16GB) DDR4 PC4-28800C16 3600MHz Dual Channel Kit
  • AMD Ryzen™ 7 3800XT
  • be quiet! Dark Rock PRO 4 Dual Tower CPU Cooler
  • XFX 5700XT (replaced with ASUS ROG 1080ti)
  • Microsoft Windows 10 Pro 64-Bit
  • LiteOn IHAS124-14 DVD Drive
  • Corsair Obsidian 750D Airflow Full Tower Case

But it has never been stable for me. It was getting BSOD maybe two times a week, with varying messages. I reinstalled windows around Christmas time which seemed to solve most of the BSOD issues, but the PC now just restarts itself randomly, again maybe twice a week. Temps are great, and it has never crashed whilst gaming - it always seems to crash whilst doing light duty stuff, emails, surfing, etc. It usually does its restarting routine within the first hour of being turned on.

I have done the following diagnostics:

  • Memtest 86 - All clear
  • Chkdsk / scannow - All clear
  • Prime 95 - All clear for hours and hours
  • Unigine stress testing - All clear for hours and hours
  • Corsair SSD Toolbox - All clear
  • Windows Memory Diagnostics - All clear

Event viewer is showing the regular shutdowns as 'Event ID 41, Task Category (63)' which is fairly generic.
BSOD viewer shows only two events since the Windows reinstall both relating to DPC Watchdog Violation and ntoskrnl.exe

In addition to the Windows install I have:
  • Disabled XMP
  • Updated SSD firmware
  • Updated BIOS
  • Updated graphics drivers
  • Changed 5700XT for 1080ti
  • Swap PSU kettle plug
  • Replaced CMOS battery
  • Reseat internal PSU cables
  • Reseat RAM
  • Disconnect reset switch
  • Taken apart my house socket to check connections
  • Changed surge protection socket

Believing the issue to be the PSU I replaced the unit with a new 850W Seasonic Focus PX-850 80PLUS Platinum but to my extreme annoyance the problem still persists.

Next I will try removing one RAM stick at a time, but I'd be surprised if that was the issue as all memory tests have been passed and it is so stable when gaming for hours on end?

Any pointers on where to look next? It is my everyday computer and I don't have any spare parts, so it is expensive and frustrating to buy replacement bits only to find out they weren't the problem.

I've been building and upgrading my PC's since the 90s (I still own a Pentium 3 that is more reliable than this!) but this has really made me think that next time I'll just buy off the shelf :-(

Thanks all, Dave

If it only crashes during light duty then I'd suspect that points to instability with rapid power/voltage switching, so if you haven't already, I'd disable all power management features in the BIOS and set Windows power plan to the highest level. Some motherboards have a setting which can enable a kind of compatibility mode with old power supplies (can't remember the name), so if you have that I'd enable it.

I'd recommend using at least 1.35 for the DRAM voltage even with XMP disabled.

What USB devices do you have?
 
Thank you so much for the suggestions. I increased the DRAM voltage, changed the power plan to Ryzen High Performance, checked the BIOS for Power Management Settings (I could only find three) and... the PC has restarted itself half way through typing this message. So I guess no dice :-(

I have a Samsung M2070 printer, Kingston Hyper X Headset, mouse and keyboard on USB.
 
Darn, that's unfortunate. Is there any other pattern to the restart? Does it happen if the PC is left doing absolutely nothing? With XMP disabled what frequency is the memory, 2133?

Have you disabled PBO?
 
Yes, it is a little disheartening. Restarts appear fairly random, always when doing office duty and not gaming though. I think it has restarted whilst it has been idle before too. Without XMP the default is 2400mhz.

No overclocking of any kind, PBO set at BIOS default 'auto' which I assume means off?

Ahh, 2400 Mhz should work even with a dram voltage of 1.2v.

It's weird it never restarts while gaming. I wonder if you'd benefit from raising more of the minimum voltages, but I'm not sure which ones to suggest.

I think PBO auto often means on.

This is utterly wierd but possibly a clue. Which games do you play? Are they online games or offline? I.e. do they make use of the network ports? Are you on a wired connection or Wifi? Whichever one you are on, is the other disabled?
 
WiFi is a good shout but I think I may have found a lead. My many searches on the internet have possibly been targetting the wrong components. It seems I'm in the same boat as a lot of other people with MSI X570 boards and Ryzen processors as there is some compatibility issues. Some have solved by having a permanent overclock, some replaced the board, some replaced the CPU:

I'm not sure what to do next though, any thoughts? If the mobo and CPU don't play nice together, which is technically at fault and which do I send back?

I can't wait for RMA and I'm getting so fed up that £220 for a new board (Asus, I guess) or £400 for a new 5000 processor almost seem like good value for money from here.
 
I'm probably looking at replacing one of the parts to keep me up an running, then RMA'ing the old one then selling whatever they send back on eBay when I know it's good. I'm going to lose money but I can't see a way round it :-(
 
Sounds a bit like the board is undervolting too much at idle.
Try a +0.01/0.02 offset vcore, and medium level LLC on both cpu and soc.

Worth a pop..

May also be worth checking for Bios updates too.

*Edited for bad numbers.. *

Do you no anyone with a ryzen cpu maybe you could swap to test.
 
This is exactly my setup and issue: https://forum-en.msi.com/index.php?...at-3800xt-crash-on-idle-bios-internet.349716/

I see that a new BIOS was released a week ago, so I'll try that first. I can also have a tinker with over-volting as you say, as I'm absolutely convinced that is the problem now.

Unfortunately I don't know anyone with a Ryzen processor, let alone anyone that would let me borrow it.

If all else fails I'll treat myself to a 5000 series I guess.

First i would buy a new motherboard then you can test the cpu its the cheapest option than buying a 5000 cpu unless you lean more to the cpu fault.

Could go b550 to keep costs down.
