This device's local mem size is too small.

Your GPU is way too old.

So there is no way to brute-force using my GPU? should i try Pyrit ?

Let's say i want to use CPU instead, how can i speed up the cracking process of a WPA password of length 8 containing only characters in the set {a-z, A-Z, 0-9}, i have 10 years as remaining time.

Edit: I don't want to use dictionary attack, because it's a waste of time against a customized password.
