nah nor do i mate, but i think it doesn't really matter that much, as long as you got a good processor, gpu, and a good amount of ram(i.e 2 gigs) then you will be good
all these different types of ram are just for bragging rights more than actual performance, i mean yes you will get a few more points in 3Dmark or a few extra fps in a game maybe? but other than that it wouldn't be noticeable unless you actually LOOK for the performance
