You can use the RMclock .exe file (http://cpu.rightmark.org/download.shtml) to solve the problem. Do NOT disable C4, as this fixes the problem temporarily but currently causes system freezes in the majority of cases. Search on the RM clock forum for how to 'disable popup mode' - that should stop the noise at a small cost to battery life.
