Hey guys hold on a minute, what is happening here isn't really tied to the Intel board at all. Windows and CPU-Z are correct and unless you got an error message when your computer started then the overclock is working.
Marine1, the reason your speed stays the same in windows and CPU-Z is because by default EIST and C1 are enabled in the BIOS. These are power saving features which allow the system to lower the multiplier when the system is not doing intensive work...
CPU-Z (depending on version) and Windows will read the default clock speed if these two things are enabled or may even read 2.0GHz (EIST and C1 set lowest multi for power saving which is 6)
What you want to do is disable C1, EIST and Thermal Control (if it's there not with Bonetrail board right now) in the BIOS.
Then in the CPU frequency control menu change the FSB or Host clock control (don't recall what it's called exactly) to 400MHz which should result in a 3GHz CPU clock. You shouldn't need to mess around with any voltages but if you do, the fist thing you will need to increase a little is FSB termination, MCH voltage and FSB/ North Bridge voltage which are all in the same menu.
13,000 is a bit on the low side but not a train smash.
I also happen to use the Asus 3870X2 Top sometimes and @ 3.6GHz I can make 20K in 3DMark06 pretty consistently. Just beware that these scores don't scale in a linear or sensible fashion so don't' put too much faith in them. It's best just to use games for testing performance as said above.
