Intel says it has root caused the 13th and 14th Gen failures.
The failures are caused by a clock tree circuit that sits in the IA core - under high heat and voltage, this circuit experiences rapid aging and degradation.
To fix this, Intel has a package of four updates
1) Issued new recommend power profiles for BIOS to prevent excessive power draw (already released)
2) Issued new eTVB boosting algorithm code to prevent excessive clock boosting behaviour (already released)
3) Issued microcode mitigation for voltage requests to prevent excessive voltages under load (already released)
4) Issued new microcode for Vshift, to prevent excessive voltages under idle (to be released in latest bios)
hopefully this means a final motherboard bios update
