The 1.3Ghz is a 100/200Mhz bus. The 1.33Ghz is the 133/266Mhz bus. Which do you have?
As for yeilds. I have heard reports that the 1.33Ghz is overclocking well past 1.5Ghz and with something like a VapoChill case or peltiers with water cooling it will likely hit the 1.6-1.8Ghz range. Liquid Nitrogen successfully got a 1.33Ghz to 2.05Ghz.
The COMPUTER is your FRIEND!
Happiness is manditory.
