Another great factory overclocked GTX 660Ti that exceeds expectations.
With the launch of the Nvidia GTX 660Ti two weeks back, we’re back again with a Gigabyte GTX 660Ti Overclock Version. As the name implies, this Gigabyte GTX 660Ti comes factory overclocked, but in order to attain the high settings a custom PCB and cooling solution is used.
The Gigabyte GTX 660Ti OC is not much different from the ASUS GTX 660Ti DirectCUII TOP which was covered alongside the Zotac GTX 660Ti AMP! Edition. The clock speeds, and even the overall length of the card, at 10.5-inches, is the same.
What makes the Gigabyte GTX 660Ti OC a bit strange, though, is the massive size of the fans compared to the rather sparse looking heatsink, and a smaller PCB still.
The basic aluminum fin structure is spread out into three parts; the largest part covers the GPU directly, while the other two cover the VRMs and memory chips. 2 thick copper heatpipes extend out from the central GPU area out to the other two, ensuring maximum heat dissipation. Plugged on top are two 100mm fans cooling off the entire heatsink below, with generous airflow to keep things cool.
This custom setup is good enough for a factory overclock of 1033MHz (1110MHz boost) on the core clock, and 6008MHz on the memory. Compared to reference Nvidia speeds of 915MHz core clock (980MHz boost) and 6008MHz memory, we have a 13% core clock speed increase.
