I found the error below in Event Viewer.
Should I change something in UEFI? (memory profile, speedstep, filter PLL?)
No BSODs, only 9 warnings after 8 days.
When last time occured only downloaded a cd, maybe did sha1 calc, no gaming or other intensive task.

000001 for BQ_PREF_READ_TYPE error
But what does this mean? google "BQ_PREF_READ_TYPE" -> nothing
Is it important? Helps to determine the source of the problem?

This is a mysterious bug:
"I have now tried different motherboards, CPUs, memory, and power supplies and
this error is still showing up now and then.
This points strongly to either FreeBSD bogus reporting, or these errors being
benign. It's hard to believe that the exact same error might occur with
completely different hardware ... unless it's being caused by the case."
