Are Amd a88x chip set motherboards overclock able?

Solution
Yes, it is overclockable with processors that are compatible. Preferably you'd want one with an unlocked multiplier. Also look for a board that has heat sinks on its VRMs and high phase power. (although I imagine they are all only 4+1)

I have the following motherboard and an AMD A10-7850K Black Edition which I've been able to overclock from 3.7Ghz. to 4.7Ghz. @ 1.5vcore with a Coolermaster Hyper 212 Evo, some chips of the same model will only go to 4.5Ghz. and require watercooling though... but yes, as long as you get an unlocked CPU/APU and a motherboard that offers options for overclocking, it's possible:
