Bios Mods -The Best BIOS Update and Modification Source

I have this Motherboard
https://www.msi.com/Motherboard/A55M-E33/Specification

I also have this 3 CPU's
AMD Athlon X4 740 "Trinity"
AMD Athlon X4 760K "Richland"
AMD Athlon X4 870K "Godavari"

First 2 CPU's works perfect, problem is with the last one (870K)
Processor mostly work fine, lets say about couple of hours, maybe a day but then just start random freezing, BSOD...
Ok, is it possible that this crashings hapend because this CPU is not on official list for my Motherboard (last one is AMD Athlon X4 860K "Kaveri") or maybe is just CPU itself failing?

Here, some screenshots from CPU-Z

Make a screenshot of regedit with expanded key HKEY_LOCAL_MACHINE\HARDWARE\DESCRIPTION\System\CentralProcessor\0
And show results of this (in the command line):
wmic datafile where name="C:\\Windows\\System32\\mcupdate_AuthenticAMD.dll" get Version
