Why Is System Agent (SA) Voltage Locked on Non-K 12th Generation Intel® Core™ Processors?

BUILT IN - ARTICLE INTRO SECOND COMPONENT
Summary

Explains that System Agent (SA) voltage is locked on non-K SKU Processors for a good starter experience of memory overclocking, not a replacement for the Pro/Best features of a K-SKU/Z-series combination.

Description

Unable to adjust SA voltage on non-K 12th Generation Intel® Core™ Processors.

Resolution

Intel expanded the capabilities of our platforms by allowing some memory overclocking features for non-K processors on non-Z-series motherboards. This was not a complete duplication of the feature set of a K-SKU processor on a Z-series motherboard. It is intended to be a good experience, not a replacement for the Pro/Best features a K-SKU/Z-series combination.
