Change log:

- Added memory voltage control for reference design AMD RADEON 7970 graphics cards with CHL8228 voltage regulators
- Now MSI Afterburner displays target VID instead of real voltage sensor reading on "GPU voltage" graph on graphics cards equipped with CHL8228 voltage regulators. These changes are implemented to avoid confusing the beginners and prevent the hysteria about voltage drop on AMD RADEON 7970 series graphic cards spreading across different discussion forums. Experienced users, understanding the difference between target and real voltages, may still unlock the previous real voltage monitoring mode via editing the hardware profiles
- Core and memory clock limits have been extended to 180% on AMD RADEON 7970 graphics cards in unofficial overclocking mode
- Now MSI Afterburner's startup daemon routine precaches VRM I2C registers state at the first Windows startup. Precached VRM state is being used to detect default voltage instead of hardcoding default voltages into the database. Please take a note that you may forcibly perform precaching later with command line switch or disable the precaching at all via configuration file if necessary and force MSI Afterburner to use the previous hardcoded database based default voltage detection
- MSI On-Screen Display server has been upgraded to version 4.3.1. New version gives you the following improvements:
o Added workaround for AMD OpenGL driver context switching issues causing abnormally low framerate in ID Software Rage when OSD is enabled
o Added workaround for AMD OpenGL driver PBO issues causing the driver to crash or perform abnormally slow during videocapture
