Added voltage control for reference design NVIDIA GeForce RTX 30x0 series graphic cards.Manually adjusted clock/frequency curve stability testing functionality is deprecated and no longer available.Now there is new 'Revert' button inside MSI Overclocking Scanner, which allows you to revert overclocked curve and memory clocks to their real defaults It means that once the scanning process succeeds, NVIDIA driver internally saves optimized voltage/frequency curve and overclocked memory clock and apply them as new system defaults after reboot, even if you close or uninstall overclocking application. OC Scanners's results are now persistent.Automated overlocking support for both core and memory clocks.New NVAPI based OC scanner implementation features the following changes and improvements:.New integrated NVAPI based implementation of NVIDIA OC Scanner for 455.xx and newer NVIDIA display.Old legacy implementation of NVIDIA OC Scanner via separate software components for NVIDIA Pascal and Turing architectures for pre-455.xx drivers family.MSI Overclocking Scanner supports both implementations of NVIDIA OC Scanner API: Such implementation simplifies the process of OC Scanner maintenance for NVIDIA, it is no longer necessary to ship updated software components to AIC partners and re-release each partners' software when something needs to be changed inside OC Scanner from NVIDIA side. Now NVIDIA OC Scanner is integrated into the driver and third-party software can natively access it via NVAPI. Starting from 455.xx drivers family, NVIDIA OS Scanner is no longer implemented as a separate software component redistributed with each AIC partner's overclocking software.Updated bundled MSI Overclocking Scanner application:.Added new integrated OC Scanner API support, please read below to get more information about new OC Scanner implementation.Added NVIDIA Ampere GPU architecture support:.MSI Afterburner 4.6.3 Beta 5 (build 16071)
