I used to underclock my nVidia GeForce 8800GT by halving it's core and memory frequencies. This would make the card about 3 Celsius cooler. I would only bring it back to stock frequencies while gaming. After three years of using the 8800GT like this, it just completely broke out of the blue. This makes me question if underclocking can be dangerous without the right precautions.
I've replaced the broken 8800GT with an ATI Radeon HD 5770. I don't want to repeat what happened to my 8800GT. So here are my questions about underclocking:
- How should core voltage be adjusted when underclocking?
- Do core and shader clocks have to match?
- Should core/shader drop clock in proportion to memory clock?
- I'm using MSI Afterburner software for my new HD 5770 because RivaTuner is outdated and won't recognize new cards. MSI Afterburner doesn't allow me to edit core voltage and shader clock for some reason. If this is the case, should I not attempt to underclock my new card?
