Overclocking using LN2
Although I do not believe in practical usage of LN2 cooling other than to post high overclocking scores, I did witness LN2 cooling being applied on the 3930X by another team from Indonesia. They managed to push up the processor to 5.4 GHz at 54 x 100. Looks like multiplier overclocking is the way to go. If the DMICLK (or CPU CLK) is adjusted too much, overclocking might just fail.
