Palit GTX 780 Ti JetStream OC Review (1600p, Ultra HD 4K)

Allan 'Zardon' Campbell November 23, 2013 Graphics, Highlights-new

To overclock the Nvidia GTX 780 Ti today we used the latest version of PALIT's THUNDER MASTER, which is supplied on the disc. It really is a terrible name for overclocking software, but as long as it works well I suppose it doesn't matter.

There is a ‘Mastermode' in the software which allows the user to apply GPU and memory overvoltage as well as applying an Overcurrent limit.

As we mentioned earlier in the review Nvidia have added a new power balancing feature which helps to get the most out of overclocking the hardware. The GPU gets power from three sources, the 6 pin and 8 pin connector and the PCI Express interface. When a user overclocks the hardware the power delivery can be unbalanced with power drawn from one source more than the others, potentially maxing out the clock speeds.

Nvidia say the new feature can direct power from one input to another, meaning that if you max out one power source then the algorithm will take more power from others to compensate. Time to test it out.

We used the settings above to get the final overclock speed. We achieved a huge 16.4% overclock on the core, increasing the speeds from 980mhz to 1,141mhz. The GDDR5 memory hit 1,914mhz (7.65Gbps effective) before artifacting would occur.
