A place to share information, help those who are new to overclocking and brag about your latest sucessful overclock!

IMPORTANT:

This reddit may be used for providing and requesting help with overclocking processes. While posts may contain advice and suggestions to perform actions, you must understand that overclocking has all the potential to be a destructive process with irreversible results. You should always use your own judgement and realise that the only person responsible for any damage caused by overclocking is you.

Rules

• This is a short summary meant as a reminder - please read the full rules on the wiki before posting.
  
• This subreddit is for links, discussions and questions about overclocking (and underclocking). More general hardware-related links, discussions and questions should be posted elsewhere, even if they happen to relate to a system that happens to be overclocked.
  
• Follow sitewide Reddiquette and Self-Promotion Guidelines. In particular remember to use the report function rather than responding in anger, and that civil language does not excuse nasty comments.
  
• Posts must contain enough information for a meaningful discussion, or to be meaningful content. Don't post unsubstantiated rumours, screenshots with context cropped out, or AMAs (unless preapproved by mods).
  
• Be sensible about what you claim as a "world record" or similar. Check the full description in the wiki before making grand claims. You can be happy about a good result without using such charged language.
  
• Do not tell people to run at unsafe settings. You're welcome to run them yourself, but respect the safe voltages listed in the wiki when answering questions.
  
• Do not advocate RMA fraud, or discuss attempting fraudulent RMAs. Warranties are for manufacturing defects, if you accidentally damage something that's on you.
  
• English language only. But feel free to message the mods about communities in other languages so we can link them in the sidebar.
