Ok, thanks all for the replies!
Bruce, that's a link to nvidia graphics drivers...

But RAM is not cheap here in Europe, in fact no computer part is...
Now here's the next part: I've bought the corsair as showed in the link. Now what should I do? Install it in the mobo and see whether that does automatically adjusts the latency? If it doesn't, I would have to underclock the corsair manually in the BIOS, right?
Thanks again
