H/W monitor problems on P7N SLI

Question

Hello Forumgoers,
First of all I want to thank the gods that MSI has such a helpful support system like this. You guys rock. Second, here's my problem:
Recently my h/w monitoring software has been giving me strange readings on my CPU. I use nVidia System Tools (v. 6.03.12), MSI DualCoreCenter (v. 2.0.5.5), and CoreTemp (v. 0.99). What happens is that sometimes the software reads my CPU multiplier at 6x instead of 9x, giving me a Core Clock of 2Ghz instead of 3Ghz. Now I don't think my CPU is actually acting up, because the BIOS consistenly gives me the correct readings when booting up (i've been checking incessantly lately since this problem arose), but there was one time that even the BIOS read the CPU multiplier at 6x. DualCoreCenter also reads the voltage on my CPU a bit lower than usual: 1.13 as opposed to 1.2 (normal). Again, the BIOS has only shown these strange readings once, but my monitoring software consistently presents me with these data. I've tried a few things, such as updating my BIOS from v1.1 to v1.3. That didn't help. Tried uninstalling and reinstalling my chipset drivers to no avail (I'm using the drivers from the MSI website: nForce v9.91). The only things that have changed recently with my system that I can think of is using my TV as a monitor (previous display was 15" CRT), allowing me to pump up the resolution, but I would think that would affect my GPU rather than my CPU. I also just recently updated my video drivers (ForceWare v190.62), but again I would think that would affect the GPU, not the CPU.
Any suggestions? I know that as long as the BIOS reads properly then my system should be fine, and through PCMark05 I'm seeing that my system is not lacking in processing power. But my h/w monitoring software has been accurate for over a year until the past week, and I'm just trying to figure out what would make it change. Any help would be greatly appreciated. If you need any more specs that I haven't provided either in this post or in my sig just let me know.
Thanks,

Looks like the power saving features of your CPU are kicking in (EIST, C1E or both).

These power saving features also cause VCore reductions.
Put your CPU under full load (Prime95) and use CPU-Z to watch the values.
