I have read it, thoroughly. I did what the guide suggested up to the point I crashed, and crashed, and crashed, and got a bit annoyed. I thought I'd give your max overclock a bash and it seems to have paid off, and saved me a good chunk of time.
I'm leaving it as it is for the time being, I'm happy where it's at.
Now I'm working on the memory voltages as the Valley score has gone down with the extra 25MHz I bumped it up by.
Good stuff.
