Zusammen mit der Turing-Architektur hat NVIDIA eine neue NV Scanner API eingeführt, die ein effizientes und automatisches Overclocking ermöglichen soll. Neben der Tatsache, dass die Software dazu die Spannungs/Takt-Kurve abläuft, soll der neue OC Scanner vor allem durch den synthetischen Workload und den dazugehörigen Stabilitätstest überzeugen. In der Praxis zeichnet sich ein durchaus positives Bild des OC Scanners, wenngleich ein manuelles Overclocking noch immer bessere Ergebnisse liefert.

Bisher funktionierte der OC Scanner aber nur mit Grafikkarte mit Turing-Architektur. NVIDIA sprach auf dem Startevent im August dazu aber davon, dass der OC Scanner theoretisch auch mit Pascal-GPUs funktioniere. Nun hat man diese Funktion offenbar der NV Scanner API hinzugeführt und der MSI Afterburner in der Version 4.6.0 Beta 10 soll dies auch schon unterstützen.

Außerdem unterstützt der MSI Afterburner nun auch weitere Funktionen der Turing-GPUs, wie das längliche Changelog verrät. Der Download der Beta-Version des MSI Afterburner ist bei Guru3D möglich.

  • Added NVIDIA Turing GPU architecture support:
  • Added voltage control for reference design NVIDIA GeForce RTX 20×0 series graphics cards
  • Advanced GPU Boost control for NVIDIA GeForce RTX 20×0 series graphics cards. Extended voltage/frequency curve editor on GeForce RTX 20×0 family graphics cards allows you to tune additional piecewise power/frequency floor and temperature/frequency floor curves. Control points on those new curves allow you to control GPU Boost power and thermal throttling algorithms more precisely than traditional power limit and thermal limit sliders
  • Hardware abstraction layer has been revamped to provide support for multiple independent fans per GPU due to introducing dual fan design on reference design NVIDIA GeForce RTX 20×0 series graphics cards and due to introducing native dual fan control in NVAPI. Both fans of NVIDIA GeForce RTX 20×0 can be monitored independently in hardware monitoring module now and can be controlled synchronically in manual mode
  • Added NVIDIA Scanner technology support
  • Added Monolithic Power Systems MP2884A and MP2888A voltage controllers support
  • Added core, memory, auxiliary PEXVDD and auxiliary 1V8 voltage control for custom design MSI RTX 2080Ti Lightning series graphics cards with MP2888A + MP2888A +uP1816 voltage regulators
  • Added VRM and VRM2 temperature monitoring for custom design MSI RTX 2080Ti Lightning series graphics cards
  • Improved hardware monitoring module:
  • Added thermal offset for CPU temperature monitoring on AMD Ryzen 7 2700X processors
  • Similar CPU temperatures are now cloned for all cores on AMD CPUs to provide more convenient and unified On-Screen Display layout between Intel and AMD CPUs
  • "Pagefile usage" graph in hardware monitoring module has been renamed to "Commit charge"
  • Added group operation notifier to the caption of active hardware monitoring graphs list in "Monitoring" tab in the application properties. The notifier is informing you that you can apply a setting to all or to multiple selected hardware monitoring graphs when you hold group operation key (i.e. or ) and hover mouse cursor over the setting that can be applied to multiple hardware monitoring graphs at once (e.g. "Show in On-Screen Display")
  • Added "Select by group" and "Select by type" commands to context menu of active hardware monitoring graphs list in "Monitoring" tab in the application properties. New commands allow selecting the graphs of exactly the same type (e.g. CPU1-CPU8 usage graphs on eight core CPU) or the graphs with the same OSD/LCD group name (for example, GPU clock, GPU power, GPU usage and the rest graphs with "GPU" group name). Such commands allow you to show similar items (e.g. all CPU usages) in On-Screen Display with a single click or rename a group for all child graphs in the single pass
  • Multi-group edit mode is automatically selected now for group name edit field when you enable "Override group name" option while holding key. You may still manually toggle this mode with + hotkey anytime when editing the group name
  • On-Screen Display item type (i.e. text, graph or combination of both) is now displayed in "Properties" column of active hardware monitoring graphs list in "Monitoring" tab in the application properties
  • Added programmable hotkey for clearing monitoring history
  • Added "Apply" button to application properties window. Now you may iteratively customize monitoring module without closing the properties to see the result on each step. Please take a note that some properties (e.g. application language) cannot be applied until you completely close properties window by design of application
  • Improved On-Screen Display layout editor:
  • System reserved variable slots 250-255 are now displayed as system variables in the layout editor
  • Added embedded graphs support. Embedded graphs can be displayed directly in the text in a separate column, it can be convenient for displaying per-core CPU usages
  • Added embedded graph width adjustment variable to the "Graph" property node
  • Added new "Graph placement" property node. You can use it to place each graph on top of text, on bottom or make it embedded in in text column
  • Added new variables to "Separators" property node. Now you may define independent separators for the graphs located on top of text part, for the text part and for the graphs located on bottom of text part.
  • Slightly altered interpretation of prolog and epilog separators. Please take a note that prolog separator is no longer automatically appended with new line symbol, so you must specify it manually when necessary and epilog separator is now displayed below the bottom group of graphs
  • The list of hardware monitoring items in "Add item(s)" dialog window is alphabetically sorted now
  • Added macroses for embedding any data from monitoring module into OSD text (e.g. prolog). You may use macroses to display anything available in the monitoring module, e.g. %CPU temperature%
  • Improved On-Screen Display hypertext formatting performance due to more optimal macro replace strategy
  • Revamped "modern web" layout. New layout is demonstrating new text formatting features including big custom framerate counter, custom embedded background and On-Screed Display header, custom benchmark and system time indicators and embedded CPU and GPU usage graphs
  • On-Screen Display layouts are saved in monitoring profiles now
  • Improved HwInfo plugin:
  • Added UPS load, power, input voltage and charge level data sources to default plugin configuration
  • Improved voltage/frequency editor:
  • Voltage/frequency editor window is now available on AMD GPUs. On AMD platform it allows you to edit core frequencies and voltages independently per each P-State:
  • Similar to NVIDIA GPUs, you may either adjust each point frequency or voltage independently with both mouse and keyboard or hold and drag single point to apply similar frequency or voltage offset to all P-states
  • Read only P-States are currently not tracked, which means that you can try to adjust the frequency and voltage for it but it will be ignored when applying the curve
  • P-States locking functionality is not implemented yet
  • Slightly increased default voltage range for voltage/frequency curve. Now you may lock voltage to lower values if you're using voltage/frequency editor to downvolt and reduce power consumption on your NVIDIA GPU. Power users may customize the range further, the voltage and frequency limits are fully adjustable via the configuration file
  • Now you may press key in the editor window to reread the curve from hardware. This feature can be useful when adjusting the curve in changing thermal environment
  • Voltage and frequency axes are dynamically scales now, so the captions do not overlap when window is too small
  • Improved hardware control shared memory interface. During the past years, external applications like MSI Remote Server were using this interface for tuning GPU hardware settings remotely from external applications. The improvements are intended to allow connecting external stress testing and automatic overclocking related applications to MSI Afterburner via this interface:
  • Now voltage/frequency curve on NVIDIA Pascal and newer NVIDIA GPU architectures is accessible via hardware control shared memory interface
  • New hardware control shared memory interface command allows MSI Afterburner to load hardware settings from external application without immediately applying new settings to GPU
  • Added notification message, allowing external applications to notify MSI Afterburner about new command written to hardware control shared memory. Without the notification, MSI Afterburner is executing external commands on each hardware polling iteration like before. Please refer to SDK and MACMSharedMemorySample source code to see notification message usage example
  • Added hardware identification info to GPU entries in hardware control shared memory. Hardware identification info allows external applications to reconcile own enumerated devices with logical GPUs enumerated by MSI Afterburner
  • Now hardware control shared memory is refreshed on delayed fan speed readback events
  • New bundled MSI Overclocking Scanner application in now included in MSI Afterburner distributive:
  • MSI Overclocking Scanner is currently supported on NVIDIA GTX 10×0 and NVIDIA RTX 20×0 series graphics cards under 64-bit operating systems only. On such systems you may activate the scanner with dedicated button from the main application window or directly from voltage/frequency curve editor window
  • MSI Overclocking Scanner is powered by NVIDIA Scanner technology, which is using proprietary algorithms to quickly and reliably test manually overclocked GPU stability or find the maximum stable GPU overclocking in automatic mode with a single click. The scanner is using embedded NVIDIA test load to stress GPU. The scanner provides you two functional modes:
  • In test mode MSI Overclocking Scanner is stress-testing your manual GPU overclocking settings during approximately 5 minutes. The result is returned as GPU stability confidence level (0% - unstable, 100% - stable)
  • In scan mode MSI Overclocking Scanner is stress-testing and slowly increasing clocks on voltage/frequency curve points and this way automatically detecting the maximum stable GPU overclocking. The result is returned as modified voltage/frequency curve and average GPU overclocking in MHz
  • Added framerate limiter compatibility settings group to "On-Screen Display" tab to the application properties. The settings include programmable hotkeys for globally disabling, enabling or toggling framerate limiting techniques of RivaTuner Statistics Server. The settings are intended to provide a way to dynamically enable or disable scanline sync technology based framerate limiting without altering application profiles, however you may use it to toggle traditional framerate limiter as well
  • Fixed kernel mode hardware access interface fix for AMD Vega GPUs. HBM temperature, GPU power and GPU voltage are no longer returning bogus values when kernel mode hardware access interface is enabled on AMD Vega series graphics cards
  • Hardcoded voltage/frequency curve clock multiplier implementation has been replaced with heuristic multiplier detection in order to provide unified voltage/frequency curve control implementation for NVIDIA Pascal and newer NVIDIA GPU architectures
  • Improved real-time voltage/frequency curve editor GUI scaling. Now GUI is scaled property when adjusting skin scaling with open voltage/frequency curve editor window
  • Improved report window, fan curve editor window, monitoring window and voltage/frequency curve editor scaling for scaling ratios greater than 100%
  • Multilanguage user interface library is DPI aware now. Main window skinned interface is no longer being scaled by OS and no longer looks blurred by default when greater than 100% DPI is selected. Now main skinned window interface can be manually zoomed with skin scaling slider in "User interface" tab, and the properties are automatically scaled by OS according to selected DPI
  • Added new skin scaling mode for power users. New mode provides better scaling performance at the expense of some scaling image quality loss
  • Skin scaling implementation is now asynchronous, so increasing skin scaling ratio doesn't increase GUI update time and doesn't decrease GUI response time
  • Skin scaling slider range has been extended from 75%-150% to 75%-200%
  • RivaTuner Statistics Server has been upgraded to v7.2.1
