This makes it easier to:
- Know the expected Lowest/Average Max Overclock values for each GPU
- Know which GPU is the best for each GPU Chipset
- Solve (or Reject) jobs that require GPU overclocking

Tabs:
- Summary (GPU Chipsets): Lists GPU Chipsets, Lowest/Average Max Overclock values, and Best GPU for each Chipset
- Details (GPU Specs & Tests): Lists GPU specifications, Max Overclock values from testing, and averages
- Builds Used: Lists the builds that I used for my overclock testing
- Notes: Any relevant notes about my testing

Note: You might have a better experience if you Download this guide, save it locally, then open it natively in Excel.

Enjoy!
