In the video provided bellow, Alexander Moroz shows how to overclock Sapphiere Radeon HD 5750 1GB GDDR5 128-bit or Radeon HD 6750 1Gb GDDR5 128-bit video card with safe methods and techniques without physical hardware modification. Theories and techniques demonstrate the maximum result of stable and safe overclocking through software. It is great practice to follow your video card temperature with MSI Afterburner software and do not go above 96c temperature under full load(heavy gaming for1-2 hours) on GPU. Sapphiere Radeon HD 5750 1Gb GDDR5 that overclocked beyond 850 Mhz showed +4 fps increase vs Sapphiere Radeon HD 5750 stock. Keep in mind, that there are some cheaper version of Radeon HD 5750 that comes with GDDR3 memory and slower GPU speeds. Those Radeon HD 5750 series can be unstable to reach the same GPU and Memory overclocking and can be very unstable due to slower GPU and cheaper GDDR3 Memory. This video should be applied to Radeon HD 5750 1gb GDDR5 Memory. Keep in mind, that the methods and techniques in this video could be applied to Radeon HD 5770 1Gb GDDR5 or Radeon HD 6770 1Gb GDDR5 memory as well and you can overclock it to 900Mhz +.
Attention: if your video card will freeze, or show some artifacts on the screen(line and dots with squares) - restart your computer and lower your overclock by 15 mhz on gpu and 15 mhz on the memory. Please keep your temperature reading on the screen (enable it in MSI Afterburner), so you will know when to speed up your fan to the comfortable level of noise vs GPU(Graphics Processor Unit that located under the fan on your video card) temperature.

Overclocking Radeon HD 5750 or 6750 safe and full guide was recorded back in 2010 for educational purposes, but can be used in 2013/2014. Author(Alexander Moroz/Moroz Academy) of this video is glad to share this video tutorial with Tom`s Hardware Forum Community. Thank you for watching and have fun with squeezing some extra performance.
