RPi Overclocking

=Overclocking configuration= WARNING: Setting any (of the below) parameters which could potentially over-volt your Raspberry Pi, will set a permanent bit within the SOC, voiding your warranty. So if you care about the warranty on your Raspberry Pi do NOT adjust any voltages!

Also at your own risk, you can try the display overscan settings from our wiki. These overscan-settings were posted on the forum, but are not confimed to work...

Overclocking options
These settings are also documented in one of the example configuration files mentioned on the config page.

Clocks relationship
ARM, SDRAM and GPU each have their own PLLs and can have unrelated frequencies. The GPU core, h264, v3d and isp share a PLL, so need to have related frequencies. PLL will be set to: pll_freq = core_freq * 2^n, for smallest n satisfying pll_freq > 600MHz.

GPU core, h264, v3d and isp should all be integer divisors of pll_freq. So core_freq=480 sets pll_freq=960. That would allow a v3d_freq/h264_freq/v3d_freq of 320 with an integer divider of 3.

Tested values
The following table shows some successfull attempts of overclocking. These settings may not work on every device and can shorten the life of the Broadcom SoC. Warranty will be voided if overvoltage is used.
