However, high clock seems to bring a little problem on the stability of the maximum performance (boost clock) graphics card. Compared to its closest competitor, namely the GTX 660 Ti from Gigabyte, using the clock no higher than the ASUS, it can produce a slightly superior performance. At first we were quite confused, because in theory the higher clock is used directly proportional with the performance, and even this mystery is solved when we monitor the maximum clock usage graph (boost) on a graphics card that has a lot of spikes (up and down). Once we add the value of the default limit power of this graphics card using GPU Tweak, the new performance of the graphics card is actually visible.
Seeing this problem, ASUS has released the latest BIOS directly spry for his GTX 660 Ti, which is claimed to increase the performance and overclocking capabilities it. As per our expectations, ASUS adds value default power limit value is still not sufficient to bear the burden of pre-OC clock is used. With this solution, the Boost maximum achievable clock could be more stable in its top position without having spiking which will reduce overall performance. For those of you who already have a graphics card from ASUS, it can download the latest BIOS at the following link. We recommend that those of you who still have not experienced to bring the graphics card directly to the distributor nearest you, as an error when performing a BIOS update can have fatal consequences.
