Regarding warranty on overclocking, this thread is here to clear up any confusion, and set the mind at rest.
When you overclock a PC you will not void your warranty unless the PC fails as a result of the overclock. If you overclock your CPU and your hard drive breaks, we WILL cover this under warranty. If however you overclock your CPU and it breaks, we wont cover this under warranty.
The only overclocking permitted under warranty is the CPU. If you overclock your GPU your warranty will be void.
Before even considering overclocking you need to ensure the following:
1. You have a good enough CPU fan. We recommend the Titan Fenrir or CoolIT Eco.
2. You have good quality CPU paste.
3. Your PSU can handle the wattage required.
4. You have a good enough case that can provide sufficient airflow.
Finally, you will need to know the correct settings for your BIOS. Save your BIOS as a profile before proceeding so that if anything goes wrong you can return back to your original profile.
BEAR IN MIND THAT IF YOU OVERCLOCK YOUR COMPUTER INCORRECTLY YOUR COMPUTER WILL CRASH, BLUESCREEN OR POSSIBLY BREAK!
