have a msi carbon pro ac b450 with ryzen 5 3600 aio cooled...oloy 32gb ddr4 3200...2x2tb sabrent nvme...evga 650w 80 gold psu...rog strix 1080ti....built around 3mth ago

ive always had occasional BSOD and numerous CDT when running games...finally got correct timings and voltage for oloy memory and things were a lot lot better

i still had annoying CDt on a cpl games but it was acceptable to an extent

then came Msfs 2020....constant CDTs

i have run memtest86 overnight with no errors at all and also used ryzen master on a 20min stability test with no issues......with aio cooler it may have got to 70 degrees by end of test

with trying everything possible in msfs and reinstalling windows/updates/drivers etc the issue persisted.

i then thought id try prime95

on blend test workers 4 5 11 12 failed instantly

on small fft test worker 11 failed within seconds and worker 12 would fail not long after

i then thought id try ryzen master to downclock  manual mode at max 4ghz with 1.28v prime95 on blend run for 10mins before i stopped it with no errors from workers

i then run msfs 2020 and i managed a 25min(approx)  VR flight with no CDT

have i got a faulty CPU or am i missing something

Have you tried updating your motherboard's BIOS?

I've been using a Ryzen 3600 for the past week, and I've had no problems whatsoever. I just installed it, and it ran fine, using 3200 16gb of RAM. No tweaking needed at all. 

So it's possible your CPU could have a defect. Just my two cents.

thanks for your opinion...im starting to think the same thing

msfs 2020 has highlighted the issues i think...i was getting constant CDTs  and occasional BSOD, no matter what i tried....it was only after running prime95 blend test and saw workers 4,5,11 and 12 instantly fail...i then used ryzen master and limited cpu from 4.2ghz to 4ghz then i ran test for 10mins without error...when i tried msfs2020 i was able to get a VR flight from one airport to the other (25mins approx.) without a single CDT or BSOD
