I know mate, i wasn't trying to get more off from him, honest

I really can't decide though, reviews are saying that even if i put 4 gig in, chances are only 3 - 3.5 will be recognised due to vista's 32 OS, that being the case, i may as well just buy 1 more gig of 6400, put that in and therefore have 3 gig?

That would then be 2 x 1 gig and 2 x 512 , would that then keep the dual channel?

Sorry for questions, but i am learning, albeit slowly!
