I believe EVGA Titans are 4-way IIRC. Also.... lol nice Shammy is nuts. This zombie is way more ridiculous than the 580 with 480 VRMs.
Evidently... that not just a titan though that's a 7970, and 480 zombie on a titan and another board for PLL.
480 pwm is for memory and matrix pwm is for gpu. Another one board pwm is for PLL. This means one Titan has 3 zombie mods.
EDIT: Wow.... he hit 1450 on the titans, with the 3970 at 5.7 Ghz.
