Just like I thought.
JUST like with Intel CPU's, lower VID GPUs overclock higher on less volts than higher Vid GPU's...and ID#'s starting with "3" are the lower Vid GPU's.
Mine's 1175v default vid and only does 1150 stable at stock. 1200 requires 1225 mv stable in BF3/3dmark, 1225 probably requires 1250mv (1225mv isn't stable).
