I went to try and overclock the CPU but apparently all of those settings are grayed out! What do?
It means that the CPU isn't unlocked. Intel has locked your CPU so that you can't overclock it
The 860 can be OCed, what are you talking about? The BIOS may be locked, but shouldn't be on this mobo unless it's from a prebuilt, like Compaq, HP or something - I've had these up around 4GHz
