oh, by the way if its XP you want to copy, forget about it. It does not boot onece copied to a new or differant computer. There are hacks avalable most of them are manual and technical so I am not going to tell you how to do it. Just payfor it, its less than the cost of buying 1 copy of doom and half-life2 togheter.
How about selling one of those Mushkin 512's on ebay and using the cash twords xp? You don't need that much. and ditching one Mouule would give you a double performance boost, because with three modules on a dual-channel system causes it to operate in single channel mode at HIGHER LATENCY. So you now have a three-way bottle neck Get rid of one.
