# Fixing System Clocks: Prebuilt
By far the easiest method, all you need to do is download the following file:
- SSDT-AWAC.aml (opens new window)
- For most users
- SSDT-RTC0-RANGE-HEDT (opens new window)
- For Intel's X99 and X299 platforms
Main things to note with this method:
- Assumes you both have an AWAC clock and it can be easily turned off with the RTC replacing it, this may not always work
- This only applies to SSDT-AWAC
- SSDT-RTC0-RANGE instead relies on known RTC names, and can only handle so many edge cases
- Doesn't really teach you anything
- For most, this doesn't matter. But to some knowing what makes your hackintosh tick is part of the journey
# Wrapping up
Once you're done making your SSDT, either head to the next page to finish the rest of the SSDTs or head here if you're ready to wrap up:
