Narrowed down my choice for RAM - suggestions?

It's between Corsair and G.Skill

Corsair

G.Skill

G.Skill
for the one above this review mentioned that a 2.8V would be better for it.
I don't understand anything about that, so is that something that can be changed on the RAM or not?

One thing about G.Skill when you scroll to the bottom of the links above, it says lifetime warranty, but when you look on their site...

...it says something different, unless I don't understand something here.
Also keep in mind, i don't plan on overclocking...just plug'n'play.
Thanks guys

 

if you are willing to pay that much for ram, pay like 15-20 bucks more and you can get really good stuff, OCZ or Corsair XMS (dont get the value crap) and its not much more.
