The problem may be due to the processor power scheme changing the base
CPU clock rate between the moment it is calibrated and the moment it is
actually used for real-time operation. Although Real-Time Windows Target
kernel tries not to rely on the "core" CPU clock, problems like this can
sometimes appear with some aggresive power-saving techniques.
If possible, please try to disable any power saving methods that can
cause CPU clock throttling or dynamic CPU clock boosting. In particular,
please look for EIST or C1E in your BIOS and try to disable that.
Good Luck, Jan
