Workaround: Only install XTU 3.0 on Sandybridge-E systems Installing it on an older system where XTU 2.X is working successfully may result in loss of functionality. XTU 3.0 does not have full backwards compatibility with previous versions of XTU. Workaround, restart application if monitor is incorrect. In rare cases it ceases displaying values altogether. Turbo Frequency monitor may display incorrect values for a short period after resuming the system from S3/S4 sleep. Workaround, after uninstalling the product, reboot the system before re-installing it. If an uninstall of the product is performed and the prompt to reboot is ignored, then upon installing the product again within that login session, settings created by the application will be deleted when the system finally does reboot.
