We were all shocked when ZOTAC announced a model which could reach a core clock of 2GHz, it seemed to be not possible. As is turned out, it is possible, but that’s the best case scenario. It would require very efficient cooling, lots of overclocking skills and some luck.
Card has been factory-overclocked to 1.2GHz, which is 204MHz more than reference model. That’s slightly lower than expected 2GHz.. Additionally memory clock was not changed and remains at 1.5GHz. But what makes this card so special? Well, according to ZOTAC, this card is capable of delivering up to 1.5V to core (default 1.212V). What is more interesting, EXPreview have easily reached a core clock of 1.4GHz.
Although, this card may not reach 2GHz clock on all units, it’s a card which has all the goodies you may expect from high-end cards. Starting from 12 Phase VRM, up to 1.5V for core, high-efficiency cooling solution, backplate, OC+ connector (for diagnosis and monitoring), LED indicators and a sexy look.
