TakTak - AMD FTW All our Intel systems would bow down at your feet if you decided to clock the ram either faster or with tighter timings.
Matty - I still win but were within spitting distance now as we are running at effectively the same, but my FSB is higher (I very much doubt you will get it up to 500 on your quad though ) which is giving me the edge.
Hicks - To speed it up you will need to push the FSB up, and change the timings to 4-4-4-12 that first 4 is the really important one
Oh and running stuff in the background will have an effect yes, mine was running with a few things in the background, firewall Anti virus etc.
