Ram: Frequency vs Amount for Gaming


I got a ram question for ya guys. I'm building a PC with a MOBO that can use DDR3-1600 ram, will have an ATI 5870, and Windows 7 64-bit. With the intent of primarily gaming and not using multiple applications at once, which choice of ram should I take: 4 gigs (2x2) DDR3-1600 timed at 7-7-7-20 OR 8 gigs (4x2) DDR3-1333 timed at 7-7-7-20. My friend says I will need more than 4 gigs of ram for gaming on Windows 7 64 bit, even if i don't multi-task. On the other hand, every forum I've visited says 4 gigs is more than enough for gaming. I guess my main question here is, with 4 gigs being the minimum, does frequency of ram matter more than amount of ram when it comes to gaming?

    4gigs is FINE! What processor are you using? If you're using any AMD or an i5, 2x2gb is perfect for gaming. If you're using an i7, you'll want 6gb (3x2gb) since the i7 utilizes tri-channel ram to get the most performance.

    In real world gaming... the difference between ddr3 1600 and 1333 is virutally nothing. Same goes for expensive memory with better lateencys, unless you're overclocking through the roof and running Crossfired 5970's, its not going to make a difference... as your games will still be limited by your graphics card.

    If you can afford to spend a little more, i'd recocmend this:

    No reason to spend $200 on rAM kits with 7-7-7-20 timings
  2. Thanks for the reply. Yeah I use an AMD processor, Phenom II 965 Black Edition, so It's either 4 gig or 8 gigs for me due to the fact I have to set it up for dual channel.
