Zotac GeForce GTX 770 Extreme Edition Unveiled
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.

__-_-_-__ love the design. one of the most pretty gfx I ever seen. so, the important question, price?Reply -
apache_lives all these cards are all pretty much the same its a damn Nvidia GTX 770 with unreliable fans that flexes more then a factory reference card+coolerReply
NO ONE CARES -
gsxrme Come get your GTX when factory overclocks, they are hot and ready! waiting for take your money!Reply -
hixbot So they upped the TDP limit with their electrical changes? Was this done in firmware, here's hoping we can mod other 770s with a hacked firmware.Reply -
catswold Clearly the GTX770 design is pretty much clocked out. None of these modified designs actually accomplishes much more than the original design.Reply
My EVGA GTX770 SC (nominally 1084/1137 boost and 7000 memory clock already OC's easily and stably to 1200/1254 boost and a memory clock of 7.6GHz). Don't see any of them factory clocked above that level.
Pretty clear the 104 chip is finished. Still, a very respectable card for a respectable price. -
Neospiral higher factory OC doesn't mean much on these boards... I have the Gigabyte OC which is set to hit 1189 boost but it regularly hits and stays at 1254. I think secretly all 770's are set this way. If this card is priced any higher than $400 it's a ripoff.Reply -
DirkXXVI Noooooooo. I just bought the GTX 770. Now theres a extreme ediition.....must have.....Reply
