I have a Z77 Pro 3 motherboard.
Still not going to make much of a difference. you could get a $400+ Z77 High End ASUS Maximus V, or whatever it's called nowadays, paired with that i3, and you're still going to see system instability when you mess around with the BCLK. as long as it's not an intel K processor like the 3570K, 2500K, 3770K, etc., matched with a Z77, Z68, or Z75 motherboard, you're much better off not overclocking if you care about a working PC.
