Hi all,

       AMD Ryzen 3400G, ASUS Pro WS X570-ACE, 64GB 2133Mhz RAM (2x32)

Started getting these errors in the event log about a week ago - and the system now crashes when under processor load. No recent system modifications (hardware or OS) outside of monthly windows patching.

A corrected hardware error has occurred.

Reported by component: Processor Core
Error Source: Corrected Machine Check
Error Type: Bus/Interconnect Error
Processor APIC ID: 1

I have seen other posts on this forum and around the web - and have tried

- Updating motherboard BIOS to latest (4805)

- Decreasing RAM frequency to 1866Mhz (that was the next option "down")

- Increasing RAM voltage from 1.20 to 1.215v

- setting CPU performance state from "auto" to "off"

- verified the CPU and case fans are fine, no dust etc. and the temp is reasonable.

- im sure there have been others that i cant remember... driving me a bit nuts.

not sure where to go next - suggestions ?

verukins, does your system crash or just log these errors?  You can talk to AMD about RMAing your processor here. Thanks, john.

The issue has to do with the on-die 'Northbridge' or Infinity Fabric.  If you are running the (IF:Memory Speed) at a 1:1 ratio, e.g. 1867/3733 you'll need to lower them both.  Try 1833:3666
