Testing:

Testing the Sapphire HD 5770 Vapor-X will consist of running the card through the OverclockersClub.com suite of games and synthetic benchmarks to test the performance against many popular competitors to gauge its performance. The games used are some of today's popular titles to give you an idea on how the cards perform relative to each other. The system specifications will remain the same throughout the testing. No adjustment will be made to the respective control panels during the testing with the exception of the 3DMark Vantage testing where PhysX will be disabled in the nVidia control panel. I will test the card at stock speeds and then overclocked to see how much additional performance is available and determine if it can run with or faster than the current fastest single GPU cards on the market. Of course, all settings are left at defaults in the control panels of each respective manufacturer except where noted. I will be using the latest drivers from each manufacturer at the time of this review.

The first thing you want to do if you plan on trying for clock speeds in excess of the limits in the Catalyst control Center you should download AMD GPU Clock tool and MSI AfterBurner to make sure you get all the functionality you can. The reason for the two utility approach is that when you set the clock speeds in AMD GPU Clock Tool and apply the setting you default the fan speed to auto. If you go back into the CCC to change the fan speed you lose the clock speeds you set in the GPU Clock Tool. Goofy, but it's what happens. Enter MSI Afterburner - this application was written by the same person responsible for Riva Tuner over at Guru3d and is an easy to use interface that is already able to work with the latest cards from ATI and their partners like Sapphire. Once you have the applications installed it was a simple matter to overclock the Vapor-X HD 5770. Since I was able to hit right up at the CCC limits on the core on the reference card I pushed the fan to 90% and bumped the clock speed to 960MHz and let it rip. Sadly it did not pass my testing at this level so I dropped to 945MHz and the card proved stable through all of my benchmark testing. Seeing as how the core clock fell a little short I set the memory clock just below the reference cards maximum and continued my testing with positive results. Temperatures were not a problem when run at the stock speeds or overclocked. When overclocked and the fan at 90% the maximum temperature I reached in my testing was 64 Degrees Celsius. At the stock speeds and the fan controlled by the drivers the maximum temperature was 74 Celsius. But the fan speed peaked at only 56% during this time. Even though I fell a little short of the clock speeds I reached on the reference card the fact is the card runs a little cooler. Cooler is always good!
