I must not be making the connection, I see no place in the bios to adjust the multiplier. The only thing there is voltage and freq, that I can see, thats why I was wondering if I need to clear cmos. I checked the Mobo manufacturer's website, and the bios thats in it is the most recent version. Is there some other way to update the bios, other then thru the mainboard mfg, or bios agent? It is a cheapie mobo, TCC brand, and the cpu is 2 yrs old, but until i figure out how to do a good OC, I don't want to risk trashing a "good" mobo. It does have an award bios and a VIA chipset.
