All the same RAM or what?

    So, one of the things I knew I was going to do before I even bought my iMac was upgrade the RAM. 4GB isn't bad but that's what my 2 year old MBP came with. According to Apple's guidelines I need to make sure I am buying 1333MHz, PC3-10600, DDR3, unbuffered and unregistered RAM.

    I've looked over the specs of the 3 candidates here and I can't find a difference. Are these really all exactly the same with different prices?

    I'm pretty sure that neither OWC nor does NuRAM have their own fab. I guess I have to wonder if Crucial does either. They are most likely slapping their name on some Samsung RAM. I have extensive good experience with Crucial but none with OWC or NuRAM. I like to save money but am I getting something less performance wise by going with OWC or NuRAM?

    I'm also a little concerned that OWC says "Install Pairs (2 at a time) for best performance". I'm not finding any evidence that my iMac has a dual channel memory configuration which would make this statement true.

    What do you guys think?

    I think the guys at OWC know what they are doing and are giving you some good advice.

    NuRAM is made of same parts as OWC RAM but the warranty is different (with OWC RAM, they send you new RAM if you report a problem but with NuRAM you have to send your RAM in for tests).

    iMac uses P55 chipset which supports dual-channeling
