Whea 19 events with 3700X

Hello,

I've been receiving WHEA-19 warnings (Unknown Error Source and Corrected Machine Check, with type of No Error from Processor Core) for my machine the last couple of months (since last year november maybe). It started with a BIOS update: BIOS 1403 (ASUS PRIME X570-PRO) fixed a WHEA-17 warning spam which was related to PCI Express Advanced Error Reporting (once caused BSOD for my nVidia Video Card also). This issue has been fixed now, but instead I'm receiving WHEA-19 warnings but only on startup and only sporadically. System is completely stable, there is no overclock except for the DOCP profile which is enabled (see specs below) everything is left on stock. There are only 5 warnings because the recent update to Windows cleared the previous ones. 

 

I managed to determine what process causes it: it is the Windows Diagnostic Policy (DPS) service which triggers these kind of warnings. I cannot reproduce the issue however because restarting the process has no effect and only happens every ~3 days.

 

CPU: Ryzen 7 3700X

Motherboard: ASUS Prime X570-PRO (BIOS: 2407)

Memory: G.Skill Trident Z RGB 3200MHz @ 1.35V 16-18-18-38, Hynix AFR (G Skill TridentZ RGB F4-3200C16-16GTZRX x2)

Video Card: ASUS ROG STRIX RTX 2070 Super Advanced Gaming

Storage: Samsung NVME 970 EVO Plus 1TB, WD Blue 1TB SSD and a couple of hard drives (2 WD Green hard drives, SATA)

PSU: Chieftec ECO 700W

Windows 10 update 2004

 

Every driver, chipset driver and BIOS is the most recent.

 

The latest BIOS from ASUS' website claims this AGESA version is - Update AM4 combo V2 PI 1.0.0.2"

 

I have fast boot enabled. Disabling fast boot from BIOS has no effect so I left it on.

 

See my reddit comments also:

Another user seems to have a similar problem (TUF gaming shares the same or similar bios):

Can anyone help me decode the corrected machine checks? What seems to be the problem? Let me know if you need any kind of data, I gladly provide anything you need.

 

Thank You and Best Regards,

Márton
