Windows 10: Crashing with WHEA errors after platform upgrade.

Hello, recently I moved from a 2700x + B450 Tomahawk Max build to a new 5800x and B550 Tomahawk Max, with all other components staying untouched apart from motherboard and CPU.The new I guess pc started crashing in certain games after this with the majority of errors reported in Event Viewer being defined as Event 46 memory, and some earlier ones as Event 18 bus/interconnect and cache hierarchy.The more time passes, the more certain I am this is just a bad CPU from the factory, since it cannot even run stable with all setting being stock from the beginning with XMP being turned off now

:)

 

WHEA Error - Please Help

Everything on my computer has been running flawlessly since building it a few months ago. For the last week, I've been getting random WHEA errors. I assumed they would go away on their own since it was a generic error every time. Today, I got fed up and reinstalled windows. About 15 minutes into the new installation, I get another WHEA error. I googled it and decided to get blue screen viewer to determine the root of the problem. I have no clue how to read this error log though and need help in a big way. Can someone please direct me on how to fix this crap? Let me know what other information is needed. I'm going crazy over here.

 

Blue screen whea uncorectable error

All I can suggest is that you start the diagnostic tests for hardware errors.



STOP 0x124 Troubleshooting [/i] Read carefully before proceeding.



Warning

If you're overclocking your system, revert back to stock clocks now.





Note Test the system once the overclock is removed before continuing with the steps outlined below.

Part One: CPU Stress Test
Part Two: MemTest86+ RAM Diagnostic
Part Three: Hard Drive Diagnostics
Part Four: GPU Stress Test




ONE [/i] CPU TEST
*Arrow Run Prime95 to stress test your CPU. Prime95 - Stress Test Your CPU - Windows 10 Forums



Warning Your CPU temperatures will rise quickly while under this stress test. Keep a keen eye on them and abort the test if overheating occurs.




TWO [/i] RAM TEST
*Arrow Run MemTest86+ to analyse your RAM. MemTest86+ - Test RAM - Windows 10 Forums



Note



MemTest86+ needs to be run for at least 8 passes for conclusive results. Set it running before you go to bed and leave it overnight. We're looking for zero errors here. Even a single error will indicate RAM failure.




THREE [/i] HDD TEST
*Arrow Run HDTune to

• check the health,
• scan for errors, no quick scan but full scan
• run a benchmark.

It may take some time, but please take the time you need to perform it properly.
When above is done please make screenshots of the following

• the health,
• the error scan,
• the benchmark incl. following
  • transfer rate,
  • access time,
  • burst rate,
  • cpu usage.

FOUR [/i] GPU TEST
*Arrow Run Furmark to stress test your GPU. FurMark - GPU Stress Test - Windows 10 Forums



Note Run Furmark for around 30 minutes.


Warning Your GPU temperatures will rise quickly while Furmark is running. Keep a keen eye on them and abort the test if overheating occurs.

 

whea warning? cache hierarchy error

I just noticed a whea warning in my event log stating a hardware error was corrected and it was reported by a cpu core. the error type was a cache hierarchy error. i know OCing can cause some of these whea errors, and it seems most people just ignore them, but im just wondering if this one is anything to worry about. my processor is overclocked, but i can pass numerous stress tests and games for hours, without any issues or errors in the even log. i think the pc my have even been idle at the time this was reported , or i was gaming . But again usually there are no errors regardless of what the pc is doing.
anyway, i was just wondering if anyone had some info on this error since googling it comes up with a bunch of different whea errors and no real explanation other than ocing can cause them.
