Well if you look at the RAM options for the Alienware Aurora 7500
it lists the "1GB Low-Latency Dual Channel DDR PC-3200 at 400MHz - 2 x 512MB" just like you said, but if you pick the "2GB Low-Latency Dual Channel DDR PC-3200 at 333MHz - 4 x 512MB" option you some how get PC3200 thats only running 333MHz? WTF.
I dont know much about ram but I understand the whole DDR is acting as double the actual frequency of the RAM thing. But I always thought if it was PC3200 it HAD to be DDR400/200MHz. So if thats true(im not sure, someone please let me know!) and its just a typo, then I wonder if your really getting PC3200 RAM and they ment DDR400 instead of 333MHz of if your really getting DDR333 ram and they ment to type PC2700 instead of 3200?
If there putting PC2700 RAM in there highend Aurora 7500 systems then thats just stupid. Especially if they make you choose between 1GB of PC3200 or getting 2GB and DOWNGRADING to PC2700.
