no the 2800 and 3200+'s aren't overclockable, you don't buy those chips to overclock. If you want to overclock to and past 3200+ XP speeds then you get a chip like the 35w 2400+ XP-M or 2600+ XP-M it's the mobile XP's which are socket A so they can fit into a socket a desktop motherboard....those are half the price of the 3200+'s and like I said can reach 3200+ speeds and beyond, I got mine up to 2.7GHz and could run stabily, currently I have it at 2.5GHz just for a lower Vcore, but that's 300MHz higher than the 3200+ XP and has the same core, cache and is half the price, and runs cooler at stock settings
