Did I do this right?

[NewBitZu]

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!

8x isn't the right multiplier. Leave the multiplier on auto, and leave the FSB at 266. That should give you 2.4. If you want to overclock, 333FSB should give you 3GHz without too much trouble.

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

As far as i know q6600 runs at 9x266, so i guess it might be old bios or something causing it to be improperly set at x8. Try changing it to 9, if you cant than maybe update the bios. The reason why you get 2.7 ghz in system properties is because it reads the deafult multiplier(x9) but with actual fsb(300), that combined gives 2.7GHz. You will probably see the same thing in 3dMark06 and other programs, but its nothing to worry about.

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?

9x266 or 8x300 either way you get 2.4ghz as an effect. 8x300 might be slightly faster but i would test it with prime for few hours as a precautionary measure. Which way you go is down to you.

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.

Well i put it to 9x266. Now everything looks fine to me. Reads 2.4ghz in BIOS and 2.4ghz in MyComputer. No more 2.7. I'm happy that way and think I'll leave it like that. Thanks for all the help.
