Hmm. My other 780 at stock started out in the mid-1,400s as well and couldn't hit 1,200Mhz, and as a result wouldn't even touch a 1,600 score in Heaven. Maybe there is something else going on then.

Also, it is based on an internal chart of 13 to 13.5 MHz increments.
Ah okay, thanks! Just found it odd why the core Mhz : offset modifer wouldn't be the same across 780 classifieds.
