1.79 is when the laptop is in high performance mode. 600mhz is when the laptop is in power saving mode. The laptop downclocks the FSB to lower the processor speed to save power. Its a very common thing on laptops. Mine runs at 249mhz sometimes

That's the same thing. When the FSB lowers, the CPU speed lowers too.

Yea, it's supposed to be the multiplier. There's a way to disable it from lowering in the BIOS on some motherboards.
