The Zotac GeForce GTX 770 Extreme Edition comes with a host of enthusiast features such as better cooling, a strong VRM and an optional LN2-friendly OTP mode.
Chinese site EXPreview reports that the Zotac GeForce GTX 770 Extreme Edition graphics card, much like previous Extreme Edition GPUs, features a wide range of premium features including a 12-phase (8+3+1) VRM that utilizes noise-free chokes and a combination of conductive polymer and tantalum capacitors. The VRM also utilizes PowIRstage driver-MOSFETs, three proadlizers and CHiL CHL8318 (8-phase) and CHL 8214-03 (4-phase) chips.
The GTX 770 Extreme Edition includes an updated variant of Zotac’s signature Gamer Force cooler that incorporates a copper heat sink, five 8 mm copper heat pipes, a “sporty aluminum shroud,” two 92 mm PWN cooling fans and a back-plate to cool components on the reverse side of the PCB.
The graphics card features factory overclocked settings of 1150 MHz core, 1202 MHz boost and 7.2 GHz memory clocks with support for further overclocking through an optional LN2-friendly OTP mode and OC+. The former is activated via a DIP-switch which bypasses a number of Nvidia’s electrical protections. The latter is an internal USB connection to a device that allows control of clock rates, fan-speeds, voltages and others.
