MSI has been known for their afterburner software for some time due to its incredible feature set. On top of allowing overclocking, you can monitor all of your clocks, voltage, temperatures, fan speeds, and even in game frame rates. That same list of things you can monitor applies to what you can actually overlay into your game. This is perfect for keeping an eye on temperatures when you are stressing your card the most. Even more impressive is recently MSI has added the ability to video capture while in game as well. This alone makes the software worth running and it’s all included for free with your MSI card!
Full disclosure: MSI’s software didn’t have full support for the GTX 660 prior to the launch so our overclocking was done using other software. We are told that the official build for the GTX 660 will be out at launch time.
Considering the impressive cooling performance of this card, I was excited to see what we would be able to inch out in extra performance with a little overclocking. I jumped right into the GPU Core clocks first. After bumping up the voltage as far as I was willing to push it I was able to give it a 106 MHz GPU offset. When put under a load this put me at 1256 MHz, anything beyond that and I had stability issues. Once done with the GPU core I played with the memory clocks and was able to take the memory from 3005 to 3086 while still maintaining the overclock on the GPU as well. All in all I was very impressed with the overclocking ability of the MSI GTX 660 Twin Frozr. We edged out a respectable overclock considering the card was overclocked from the start.
