We have seen many successful overclock of the engineering samples Core 2 Extreme QX9650 (3.0 GHz) to 6.0 GHz frequencies with liquid nitrogen. However, yesterday appeared a warning that some processors Core 2 Extreme QX9650 has the so-called cold bug when working at temperatures in the range 60-90 degrees Celsius below zero.
Of course, this problem appeared only in some disappointed overclock lovers , but there many of those who use liquid nitrogen without problem. The threshold cold temperature of each processor copy is strictly individual. There is no reason for panic . In addition, many owners of Yorkfield processors will be happy to reach the 4.0 GHz while using only air cooling.
