Frequently Asked Questions
In most cases, different modules in one board is behind DDR5-PMIC-TMP. Poor quality CPU controller, frequency too high and dust in slot can trigger it too.
"Disable XMP profile in BIOS" clears up most DDR5-PMIC-TMP reports by itself. The remaining steps above cover what's left.
Yes — DDR5-PMIC-TMP is a critical-severity error and can lead to data loss or hardware damage if it's ignored. Don't put off the fix steps above.
You shouldn't need to. Work through the guide above first — a reinstall is only worth considering if none of those steps help.
MemTest86 is strongly recommended if DDR5-PMIC-TMP occurs repeatedly. It runs overnight and tests all RAM slots independently. Even a few errors in MemTest indicate faulty RAM that should be replaced.
