Over Clocking My Card
Over Clocking My Card
Hey,
The tool I usually suggest for GPU overclocking is MSI Aftershock:

It’s tough to pinpoint the ideal settings since each graphics card varies. Your HD 7750 can perform either better or worse than another HD 7750, so you’ll have to rely on testing.
Begin by opening MSI Afterburner, increasing the Core Clock by 50 MHz as a starting point, and raising the Power Limit by 20%. Perform a GPU stress test such as Unigine Heaven: https://unigine.com/products/benchmarks/heaven/
If you notice no issues, increase the core clock another 25 MHz and retry. Don’t forget to click the 'Apply' button in MSI Afterburner to save your changes.

It’s difficult to pinpoint the optimal settings for each card, since every graphics chip behaves differently. Your HD 7750 can perform either better or worse Core Clocks compared to another model, so you’ll have to rely on experimentation.
Begin by opening MSI Afterburner, increasing the Core Clock by 50 MHz as a starting point, and raising the Power Limit by 20%. Perform a GPU stress test using Unigine Heaven: https://unigine.com/products/benchmarks/heaven/
If no issues appear, increase the core clock another 25 MHz and retry. Be sure to press the 'Apply' button in MSI Afterburner to save your changes.
Throughout the process, keep an eye on the GPU temperature!
Continue until you notice any artifacts or crashes. When they appear, you can either reduce the overclock slightly and reattempt the test with Unigine Heaven, or begin adjusting the card’s voltage. If you choose to raise the voltage, proceed carefully—only increase it in small increments of a few mV at a time, and avoid exceeding stock levels. Higher voltages generate more heat but can help the card reach higher clock speeds.
To access the Voltage slider, navigate to the options and check the 'Unlock Voltage' box.
