Specialists from PC Games Hardware flashed an Nvidia GeForce GTX Titan X graphics card with a modified BIOS that increases voltages of graphics processing unit and memory. Thanks to increased amount of power available to the components, the graphics adapter could be overclocked to 1550MHz/8000MHz (core/memory). The journalists used Arctic Accelero Xtreme IV to cool-down the graphics card.

Exact voltages of GPU and memory were not revealed, but the reporters indicate that the graphics board managed to remain perfectly stable at 1.50GHz/8GHz in all games in 4096*2160 resolution. Not all titles worked stably at 1550MHz GPU frequency. Still, even at 1.50GHz GPU clock-rate the graphics board demonstrated unprecedented performance for a single-chip graphics adapter.
It is surprising that Nvidia’s GM200 graphics processing unit, which contains 8 billion of transistors, can run at 1.50GHz at all. Typically, complex GPUs are hard to overclock.
