The ASUS GTX 560 Ti 448 cores DirectCU II is an excellent, almost perfect, product. We started our overclocking experiment from Samsung’s 0.4ns memory chips and found them capable of working at 4700 MHz. There were occasional image artifacts, however, so we had to roll back to 4660 MHz. The memory frequency grew by 22.6% from the default 3800 MHz, which is quite good for an Nvidia-based card with a 320-bit memory bus.
The GPU could only be stable at 810/1620 MHz (+10.7%) if we didn’t change its default voltage of 0.975 volts, so we had to increase the latter. The top stable GPU clock rate turned out to be directly proportional to GPU voltage. Unfortunately, the maximum voltage we could select was 1.1 volts, so we stopped at 930/1860 MHz. This is 27% above the default GPU clock rate. Although such a number can hardly impress the user of a 28nm Tahiti GPU, it is indeed an excellent result for Nvidia’s current 40nm chips with air cooling. The overclocked ASUS GTX 560 Ti 448 cores DirectCU II outperforms the more expensive opponents at the Performance settings. It is also ahead of the GeForce GTX 580 and almost as fast as the Radeon HD 7950 in the Extreme mode. Source
