Hehehe, or maybe there is a reason they are low end! Intel even added a throw back VID, remember? 1.3500 for the Chips that didnt quite make it at 1.3250, lol!
But yeah, their lesser series is pretty much all toss backs that couldn't be used at any other speeds and voltages.
Most of those series will be 1.3250.
Yee haw!
