Unable to adjust SA voltage on non-K 12th Generation Intel® Core™ Processors.
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.
The table below shows the expectation:
| Non-K SKU Processor with Select PCH SKUs | K SKU Processor | |
| VccDDQ Voltage Control | Yes | Yes |
| PMIC Voltages1 | Yes | Yes |
| SA Voltage Control | No | Yes |
| Memory OC Expectation | Starter/Good | Pro/Best |
