well depending on your budget and how much you wanna OC you might wanna look into the ram i'm using. I've heard people putting 2.4V into it w/o problems (though i won't risk it) and getting up to DDR2-1066 @ 4-4-4-12 timings...

although it says 2.0V-2.1V it defaults to 1.8V on the board so all you have to do is fix that and set it to 400mhz manually and it works just fine.
like i said unless you've got the money and plan on OCing a decent amount you should probably get something else as this is pretty high quality and expensive...Gskill also has a good value DDR2-800 kit too that would work pretty well but just not OC like crazy like this kit would.
