AMD Stability Issues Suggestion

[Ivan Dossev]

For anyone experiencing these issues:

• L0 cache errors
• L3 cache errors (was most common for me)
• MACHINE CHECK ERRORS
• Random restarts
• Windows BSOD

My system is an AMD Threadripper on a Gigabyte TRX50 AERO D motherboard.
The 'Advanced Memory Settings'->'Power Down Enable' DRAM feature is very problematic if left on 'Auto' or 'Enabled'.
It has a tendency to reset back to 'Auto' after a power reset or hardware changes, and has been a sneaky repeat problem for me.
Try to set this to 'Disabled' before assuming the CPU or other hardware is defective.

In addition, I am using the Expo 1 profile for the RAM successfully.
However I did find these extra options problematic under load, so I leave them 'Disabled':

• Low Latency Support
• XMP/EXPO High Bandwidth Support

They are less of a problem because they stay disabled between hardware changes or power resets.
