Did I do this right?

So I bought a Q6600 and Gigabyte EP42-UD3P mobo. Stock it ran the chip at 2.1ghz. It should be 2.4ghz. So I bumped the CPU frequency which was at 266 to 300 and now it reads 2.4ghz properly in the easy tuner software. BUT, when I right click My Computer and properties, it's saying, Q6600 @ 2.4ghz and then under that it says 2.7ghz. What the heck? I'm not really trying to overclock the system at all, I just want to get my CPU running at it's stock speeds. My multiplier I left at 8 and voltage settings all on auto. Any help or is this right? Thanks!

There is no auto. 8x is the default. If I put the FSB back to 266, my CPU speed goes back to 2.1ghz.

Ok man, as long as I'm not overclocking anything, I'm happy. I can't imagine it being an old BIOS. The mobo is fairly new. So should I just put the multiplier to 9 and back down to 266? Is it safe with it cranked up to 300? I'm on stock cooling for the chip. I just wanna run it stock because I feel cheated running it at 2.1ghz when I bought it for 2.4ghz. You know?

And to further complicate matters ...
You also have SpeedStep to contend with. A stock Q6600 runs at 266 MHz X 9. Most motherboards seem to ship with SpeedStep enabled. What happens is the BIOS steps down the multiplier to X6 (1.6 GHz) under no or light load, then goes to full speed under load.

The late model G0 version of the chip is a great overclocker. Mine has a VID of 1.2625 volts. Look at that as the core voltage that the chip automatically selects when you put it in the motherboard. My Q6600 will run at 3.0 GHz with a core voltage of 1.225 volts.

My point here is that 3.0 GHz (333Mhz X 9) should be safe with the stock heatsink. You can download a temperature monitoring utility to check.
