ASUS, Gigabyte and ASRock offer cFosSpeed OEM versions for certain motherboards. Updates for these OEM versions are available at motherboard manufacturer's website. If you install a regular cFosSpeed version over your OEM version, a 30 day trail period starts after which you can either buy a cFosSpeed lifetime license from us or uninstall cFosSpeed and install the OEM version again.

If you like cFosSpeed we would appreciate you buying the lifetime license from us. Your benefit will be access to all future cFosSpeed betas and releases. Although our OEM partners offer updates, we typically have a faster update pace with new versions and new features.
