Changing ati sdk to 2.1

[Wes1180]

I feel silly for asking this but whatever.
I am unsure as to what version I have but it is most likely the most latest one, but how can I change the version to 2.1 in order to improve upon my mhash etc?

I am using windows 7 64-bit and a 6950 (not unlocked to a 6970 yet as I need a better case first).

I just found this

"SDK 2.1 not supported on 69xx. "

So nevermind then, thanks for your help though
