Trouble overclocking e6750 with P5k3 Deluxe

[rob feature]

For some reason, I can't change the CPU Ratio or FSB Frequency in the bios. It's like something's locked. I can change all the other parameters in the bios, but just not those 2.

Thanks in advance for any ideas.

K, never mind...got it figured out. Everything else in the bios, you select with the enter key. You don't actually have to select those...just type the numbers using the keypad

Thanks anyway!
