ZOTAC GeForce GTX 770 Extreme Edition graphics card is only limited to the Chinese market and its one of the most customized GTX 770 launched till date. It is based on a totally custom designed PCB featuring 12 phase VRM with high quality components such as tantalum capacitors and noise-free chokes. The GPU ships with massive overclocked clocks, 1150 MHz on core with 1202 MHz GPU Boost 2.0 and 7.20 GHz memory clock effectively. ZOTAC GeForce GTX 770 Extreme edition also comes with an OTP mode which is designed for LN2 overclocking and disables a few electrical protections on the GPU.
