PC Crashing

[Whitsy]

Hi all!

I feel I have the worst luck regarding PCs...for 5 years on and off, for one reason or another, my PC keeps randomly crashing, locking (never a blue screen) and today I finally saw an error code in Event Viewer - though it could be unrelated.

Bit by bit I've replaced every single component in the PC - all to no avail - which means either I have really bad luck or I'm an idiot.

Usually happens under load when gaming - I've monitored CPU and GPU temps - neither breach 70 degrees.

Everything is factory settings, other than DOCP on the ram to get it to the specified 3600mhz

Hardware:

Asus B550-F Mobo
Ryzen 9 3900XT
16 GB T-Force Xtreeem DDR4 3600MHz
Strix 3080
RM1000i PSU
NZXT Water Cooler
M.2 SSD (Purchased within last 2 months)

Error I spotted in Event Viewer:

A fatal hardware error has occurred.

Reported by component: Processor Core
Error Source: Machine Check Exception
Error Type: Cache Hierarchy Error
Processor APIC ID: 9

The details view of this entry contains further information.

Any ideas? I'm at a complete loss!

Cheers

Note - some research points to Windows Fast Boot being an issue - which I've now turned off and will monitor

Disable the DOCP try that

Cheers! Won't it severely impact the memory though given it limits it to 2400MHz?

Thanks for the info.

I did end up having a play with the RAM Calc - B550 isn't in the list of boards on there - read you can use X570 instead. Either way - copying info recommended into the bios made it fail to post.

Out of interest I put the DOCP profile for 3600 on and booted to memtest86 from a USB - left it to run for 3 hours and it passed.

Annoying thing is I can't get it to consistently crash. Sometimes it will be playing a game full tilt, others doing nothing stressing at all like watching a youtube video
