"Well needless to say, I want to improve on the 10MHz overclock that ASUS ships stock. With such a massive cooling system and the voltage tweaking capability baked in, I have high hopes of success with this card. I began in earnest trying to find the upper limits of this chip. Opening up ASUS' bundled Smart Doctor utility with GPU-Z to verify settings, I set the fans to 100% and ran MSI's Kombustor utility to warm up the card and provide background stress as I push the card. I began moving up 10 MHz at a time, leaving the voltage at stock for now, allowing five minutes in between bumps to verify moderate stability. I continued doing this up to 865 MHz, where I finally crashed. I went back down to 860 MHz and let it burn in for 15 minutes with no errors and the GPU core sitting at a mere 62 degrees Celcius, I knew this was going to be fun. I nudged up the voltage and continued, swapping between voltage and clock speed as I went. I maxed out at a mind-numbing 925 MHz on the core at 1.1v and 988 on the DDR5 running at 80 degrees Celcius. This card's a spunky one, boys - that's nearly 200 MHz over reference speeds."
Any major computer upgrade generally requires a full software reinstall too. No so if you heed the advice in the guide to Upgrading a Motherboard without Reinstalling. PCSTATS Tips
