PC Processors

[tyguitaxe]

Hey guys. Back in June/July I bought a 5900X and ever since I've been having a nightmare of a time. Everything will be running smooth and then I'll go to play a game (typically Guild Wars 2) and sometimes it's fine and other times I get a BSOD! My temps look fine in HW Monitor. I've removed all overclocking including my RAM so it's now at 2400MHz instead of 3200/3600MHz. I have an B450 AORUS M motherboard, RX 6800 XT GPU, 32GB Kingston FURY Beast RAM. I run MemTest and my RAM passes. I run CPU tests and it does just fine. What the heck is going on?

Here's the latest dump file: https://drive.google.com/file/d/1PUbHhWIlhpVrLVg8cRsu21o_keot31RV/view?usp=drive_link

Did I just get a lemon of a CPU?

tyguitaxe, please put your dump file somewhere I can DL it. I do not have a Google account. Thanks, John.

Here's a OneDrive link? https://1drv.ms/u/s!AsZ6CZS8FIwqzTLDA-0h9IlrNFo3?e=5fGzvV

tyguitaxe, thanks. The bug check code is 0x0124, WHEA_UNCORRECTABLE_ERROR. Are you getting lots of these? Where did you DL the AMD drivers? Please DL all AMD drivers from here. Is your memory on the QVL for the new processor? Thanks and enjoy, John.

I did download all CPU drivers from AMD's site, GPU drivers are through Adrenaline software. RAM is on the QVL on AMD's site. I used to get a ton of crashes and similar errors, but about a month ago I unchecked XMP in BIOS and it seemed to run smoother.

So your system ran fine prior to the CPU upgrade? What CPU did you upgrade from? What power supply do you have? Do you have all 8 pins (4+4) of the CPU power connector plugged into the board?

[tyguitaxe]

I upgraded from a 3600 and the pins should all be plugged in although you have me doubting myself now. My PSU is Corsair RM850e

[FunkZ]

Power supply should be plenty capable, GPU is only ~300W and CPU ~130W at stock. Some Micro-ATX boards go cheap on the power handling but the B450 AORUS M has an 8pin CPU connector and appears to have enough phases to handle the 5900X assuming adequate cooling. What is your CPU cooler and does it provide any airflow over the motherboard mosfets? How hot are those components getting when you get these BSODs?

[tyguitaxe]

In the past when this was happening a lot more, I was seeing temps anywhere from 60s to 80s so I don't think it's a temp thing. My cooler is the Noctua NH-U14S with a single fan. I have no idea if it's providing airflow over the mosfets. How would I check that? Other cooling includes 2x intake in the front and 2x exhaust (back and top). I do want to note that I'm using a Cooler Master NR400 w/ ODD in case that's important.

[FunkZ]

Circled are the power components on your board. Only the rear has a heatsink installed, which may be receiving some airflow from your tower style cooler. Or they could be too hot to touch. HWinfo should also give you mosfet temps.

[tyguitaxe]

Wow, I'm so sorry I'm just now responding. That image helped a ton and I've been doing some testing.

In HWinfo, I found VRM MOS temps would get much higher than VSOC MOS by about 20+ degrees while playing. I then ran prime95 a few times and found that VRM MOS would get to 120+ degrees. This has me wondering if my motherboard is the problem. However, I shared the dump files in a tech support subreddit and someone there said the problem is probably my CPU because the error says (Machine Check Exception).

I'd appreciate any additional thoughts you may have. Should I just RMA my CPU? Do I just replace my motherboard?

The motherboard vrms are not capable for a 5900X.

HUB review B450 VRM of the ATX (more vrm) model failing (overheating) on a 2700X O.C'd.
