This is my first upgrade in years so im not very familiar with all the latest cpu tech. Im using an ECS G31T-M mb w/Intel Quad Q6600 processor. The bios shows "Ratio Actual Value: 9" and the CPU frequency is 266. 266 * 9 = ~2.4 so that seems right. However, CPU-Z shows my multiplier at 6 and my bus speed at 266 so my core speed is 1596 and not 2.4. Shouldnt my multiplier be at 9 like it is in my bios?

that's a energy saving thingy from Intel, it throttles down the CPU frequency when Idle, u can disable it in the BIOS
 
It's EIST (SpeedStep); your multiplier is changed to 6x when idle (and the voltage is reduced, provided you've not set a custom voltage) to save power. It'll go straight back up to 9x when there's load on the CPU though, so it's not doing you out of processing power. There's no real reason to disable it unless it causes a problem.
 
SpeedStep can cause system inestability if u are planning to overclock.
 
Ive tried both disabling and enabling Intel EIST in the bios but its still showing multiplier of 6 in CPU-Z. What else do I need to do to disable this?
 
SpeedStep rarely causes overclock instability because it won't touch the voltage if you set a custom one. I'm not saying it never does, but you'd be pretty unlucky, and it's worth trying it on for some power/heat saving. The best idea may be to turn it off while you find a stable overclock, then try turning it back on to see whether it's still okay.

The C1E option may also need to be turned off if you're trying to disable it.
