One of my less than 18 month old 2 gig Corsair Dominator DDR 2 800 ram modules went kaput where I had to send both back for warranty and now running on a single 2 gig stick 667 generic brand in effect losing dual channeling. Makes quite a bit of difference which is to be expected. Corsair 4 gig DDR 800 dual and the generic 2 gig DDR2 667 Anyways I'm not real happy with the corsair ram and hopefully I will get a warranty replacement in a week or two. I've been contemplating buying the below 2 sets x 4 = 8 gig of Kingston 1066 ram for around 250 bucks delivered. Any thoughts on this, wait for the Corsair ram or get this Kingston set as I do have a Win 7 64 bit install.
