Which memory should I choose?

I want to put an order in for 4 GB ram tomorrow morning. I'm building an AM3 PHenom II system - DDR3 has me a little confused. < this is my 2nd PC build >

I see RAM that is for i5 and i7 systems @ 1.65v -
And the rest seems to be set to run @ 1.5 v

Are these two interchangable in an AMD system? Also, besides clock speed - should I default to the lowest timing - or is there something else I should look at.

G.Skill DDR3 1600 - 1.5 v - compatible with i5 & i7 $96.99

G.Skill DDR3 1333 1.5v ( doesnt' mention i5 or i7 ) $ 89.99

G.Skill ripsaw 1600 1.6v - lower latency < no mention i5 or i7 ) $100.00

G.Skill DDR3 1333 - lower latency 8 @ 1.5v $93.99

I've had good luck with G-Skill and Kingston - and really like G.SKill as a company. My main focus on this build is Value - and reliability vs Performance on this build. Although all things being equal - I'd take the best performance for hte money.

Besides clock speed - and average User rating - I'm kindof stumped at what I should look @ to choose one RAM set vs another. Any guidance would be appreciated

  1. I would buy one of these kits.
    I own the Ripjaws one nice and fast.
    DDR3 dual channel ram works on Intel and AMD there's no difference.
    All mobo's default to 1333 so you have to adjust the speed and timings in the bios.

    You sure about the compatibility - I don't want to have to RMA this stuff.

    I see this on your link
    Specifically Designed to compatible with Intel Core i5 and Core i7 for Intel P55 motherboard

    Will this run with AMD system? Or is it specific to run with P55 motherboards?

    Yes it will like i said there's no difference ram is ram.
    That's just marketing.
    If you read the reviews plenty of people have it on AMD builds.
