Oh did not see it was a gateway... And Pc 533 is not DDR2... 400 is a bottle-neck compared to pc 533. as for Ultimate ya you will need more. I have it and I have 2 gigs of pc 8000, it does alright..

i am trying to get my parents to buy Home Premium, and i will get half a gig now and another half later on. Considering that our new Gateway Desktop has 2GB DDR2 PC533 and it works great, i think PC3200 is good. The computer i ahve been talking about is the one in my pull down thingy

pc 500 is not drr2.. its just ddr in dual channel. Just like pc 400..If you have DDR2 then you cannot use pc 400 as it is only 184 pin it wont fit..

Did not mean 533 (meant 500)

Here is DDR 400 (pc 3200)

DDR2 is 240 pin ram so before you order any ram you should check if you have either DDR or DDR2

oh. yeah just standard DDR. i know that i have standard 184pin DDR. I am planning on half a gig now and more later on.
