Why one Earth would you want to downclock your cpu? It downclocks itself to save power. It does not run at 3.4 all the time, probably more like 1.8.
If you download cpu-z you'll see what it's actually running at.
I wasn't really planning on that and ok dude but if your not going to provide and answer then don't post on my thread at all :P. I hate criticizers .
