You need to install this windows update: http://support.microsoft.com/kb/896256
Micro$oft update info:
"Correct TSC synchronization
On some operating systems, the processor TSC may change the rate at which it counts. Additionally, the processor TSC may stop counting when specific processor power management features are used. On computers that have multiple processors, the TSC is typically the operating system hardware timer that supports calls to the kernel KeQueryPerformanceCounter function. When TSC does not increment monotonically, system components that use the kernel KeQueryPerformanceCounter function may not work correctly. To address this problem, Microsoft makes it possible for the ACPI Power Management Timer to be used as the operating system timer that supports the kernel KeQueryPerformanceCounter function. However, some programs may directly access the TSC by bypassing the Windows timer APIs. The multiple-processor Hardware Abstraction Layer (HAL) makes sure that the TSC registers on all processors on a multiple-processor computer remain closely synchronized. Therefore, access by system software that may be directed to different processors does not return different results. This change makes sure that the multiple-processor HAL continues to correctly synchronize the TSCs across all processors on a computer, even if the ACPI power management timer is used as the operating system hardware timer.

M$ states that this update is for xp sp2 only, i use sp3 and the installer did its job, upon reboot the sync issues are gone
