|1st of all, do the math. 3.067GHz / 133MHz = 23x multiplier. Does you motherboard support 23x? I highly doubt it. Apparently the multiplier is defaulting to 16x, which is probably the highest your board supports...or did you set it to 16x?|
All mobile CPUs have an unlocked multiplier. This is done so that the CPU speed can be varied thru Intel's SpeedStep technology. SpeedStep also varies the CPU voltage. When a laptop is under light load, SpeedStep will automatically lower the multi & volatge. This keeps the CPU temp down & it lowers the power requirement, thus providing longer battery life. As demand/load increases, so will the multi & voltage.
You're lucky that CPU even runs at 1.6GHz. Many times when a mobile CPU is installed in a desktop machine, the multi will automatically drop to the lowest allowable...usually about 6x. It can be overridden in the BIOS though IF the BIOS provides multi adjustment. If the BIOS doesn't allow adjusting the multi, you'd be stuck at 600MHz. Remember that mobile CPUs are not designed for desktop machines, therefore their CPU info is NOT contained in the BIOS. Their settings ALWAYS have to be manually configured.
