Actually you got your "hardware math" wrong, 12x133 is 1600. 33 is actually representing 1/3 of 100, 66 represents 2/3 of 100, etc.
NO, most 1.2A's won't go that high. Been there, tried that. I recommend a 1.1A at 1466MHz/133MHz bus instead, because you're far more likely to get there.
My last couple 1.2A's would NOT hit 1600MHz. The one I tested with the most wouldn't go past 1480MHz with stability. And that was at some really sucky bus speed.
My 1.1A runs a little faster with stability, but at higher voltages than I'd recommend anyone use. People are experiencing "CPU sudden death" on Intel .13 micron CPU's with as little as 1.75v. I recommend 1.70v or less. At 1.65v, my 1.1A@1466 runs stable and cool enough for the stock cooler.
