>and allowed you to increase the multipliers on non-K processors

Wasn't this the other way around, allowing you to increase multipliers on K processors on the lower end chipsets? Or was both possible at some point? I remember getting baited into buying an H87 board that could overclock a 4670K until a bios update removed the functionality completely.

Should be so, multiplier is locked at cpu level not firmware.
