Random Bluescreen Crashes On Server 2019/16 With No Consistent Reason

Hey

I've been struggling with these rather odd and entirely random Blue Screen crashes on my server. I had a hardware upgrade last month and ever sicne then there has been an endless torrent of issues. I have managed to remove a lot of them, 2 errors were due to 2 dead HDD's and another down to a broken Raid card but i still have a Blue screen which is caused by a system "Bug Check", every time a bug check runs it seems to kill the machine and each time for a different reason, from 0x01a to 0x04b and a few others. I have a selection of memory dumps from these which i am trying to understand but memory dumps are a new thing to me and I am fairly sure that i am missing most of the constructive information here.

What I have done before this is double check every running drive is free of errors , I've had memtest and the windows memoery tester run on the machine all seemingly to no avail.

The dumps can be found here - Mem Dumps

The server manufacturer will be your best resource to debug problems with the hardware.

Sounds good. This doesn't mean it can't or won't work but it does leave the burden of vetting all the components and drivers to the end user to do.

Hi,
According to your description, Multiple different Bug Check is usually a hardware problem - even more likely on a recent build or major upgrade.

Bug Check Code Reference
https://docs.microsoft.com/en-us/windows-hardware/drivers/debugger/bug-check-code-reference2

Due to security policy, community support cannot download and save user’s personal data such as dump or log files, please install WinDbg from Microsoft website and analyze crash dump files.
https://docs.microsoft.com/en-us/windows-hardware/drivers/debugger/debugger-download-tools

If you really need crash dump files analysis support, open a support ticket with Microsoft.

If it is determined that it is a hardware problem, I am afraid you still need to seek help from the manufacturer.

Hope above information can help you.

Please perform the following steps:

1) Upgrade the BIOS: F50 > F61C
https://www.gigabyte.com/Motherboard/B450M-DS3H-rev-1x/support#support-dl-bios

2) Indicate when each of the RAM modules were installed

3) Run this script using administrative Powershell > post an image or share link

 [Cmdletbinding()] 
 Param( 
     [string]$Computername = "localhost" 
 ) 
 cls 
 $PysicalMemory = Get-WmiObject -class "win32_physicalmemory" -namespace "root\CIMV2" -ComputerName $Computername 
     
 Write-Host "Memore Modules:" -ForegroundColor Green 
 $PysicalMemory | Format-Table Tag,BankLabel,@{n="Capacity(GB)";e={$_.Capacity/1GB}},Manufacturer,PartNumber,Speed -AutoSize 
     
 Write-Host "Total Memory:" -ForegroundColor Green 
 Write-Host "$((($PysicalMemory).Capacity | Measure-Object -Sum).Sum/1GB)GB" 
     
 $TotalSlots = ((Get-WmiObject -Class "win32_PhysicalMemoryArray" -namespace "root\CIMV2" -ComputerName $Computername).MemoryDevices | Measure-Object -Sum).Sum 
 Write-Host "`nTotal Memory Slots:" -ForegroundColor Green 
 Write-Host $TotalSlots 
     
 $UsedSlots = (($PysicalMemory) | Measure-Object).Count  
 Write-Host "`nUsed Memory Slots:" -ForegroundColor Green 
 Write-Host $UsedSlots 
     
 If($UsedSlots -eq $TotalSlots) 
 { 
     Write-Host "All memory slots are filled up, none is empty!" -ForegroundColor Yellow 
 } 


4) Post a share link for msinfo32 saved as NFO

Hey,

Took me a little while to get the time, Thank you for the reply! I went through these steps.

Bios has been updated just now :)

There are 3 4 8gb modules and 1 4gb, 2 were purchased last year brand new (Slots 2/1 4/8GB) while the other two were pulled from a previously unused and dysfunctional system (Slots 4/3 8/8GB) for a total of 28GB or 32.2GB including committed.

Having run the script the following output was recived... 1PDMEdEyWhhWqeZvxFhXqbAZefNi9kHxp

And the saved info files in both .nfo and .txt format just in case can be found here 1tdgMb-JKu8bydbnf4UYstBiGGi-p7wfw

All of the memory dumps were downloaded and debugged.

There were no misbehaving drivers.

The problem is likely related to RAM, DIMM, or motherboard.

The most likely problem is incompatible, mismatched, or malfunctioning RAM.


Open the motherboard manual.

Look for information about optimal DIMM when installing only one and only two RAM modules.

View the applicable Qualified Vendor List (QVL).

Remove all RAM modules.

Test RAM on the QVL (evaluate computer stability / instability).


When purchasing RAM:

a) Select RAM modules displayed on the QVL

b) Purchase in pairs with matching SKU

c) Consider RAM manufacturers that guarantee compatibility

d) Consider RAM manufacturers that have lifetime warranties
