What is the advantage of having faster memory?

I'm building a new Core i7 3770K gaming rig this Christmas, and I can't decide if I should get 1600MHz DDR3 RAM or 2133 MHz RAM. Both kits have cl9 timings.

Are there any noticeable advantages to having faster memory, particularly in gaming?

More about what advantage faster memory
  1. Not much. The Intel memory controller can't take advantage of the faster speed. Some premium ram is double the regular cl9 price; I won't pay it, not when 1600 8 gb kits are less than $30 with rebates.
  2. Actually after reading this article http://www.anandtech.com/show/6372/memory-performance-16gb-ddr31333-to-ddr32400-on-ivy-bridge-igp-with-gskill
    the Processor you selected is one of the few that DO take advantage of faster memory. With gaming the scenarios are so different that the important thing to have is the start to finish time that memory takes to process. The tRAS # the number after say 9-9-9-24 the 24 is the tRAS. That big money could save you a Nano Second or two... So think about that. Bang for the buck or juice from the squeeze. I am going to get this Kingston for 5 bucks cheaper then the Gskill competition with a LIFETIME Warranty and CAN be O.C'd if you dare....Kingston KHX1600C10D3B1K2/16G 65.00 with promo code for the next 30 hours-2BLKNVMW12 <10.00> off
  3. There are a few games (such as Civ 5) which use a lot of RAM bandwith. Though most of the times, RAM faster than 1333 or 1600 Mhz at mid latency is mostly useless unless if you're using an AMD's APU.
  4. The question was speed not size. Everyone knows size matters. Otherwise we would not measure it. LOL!

    So memory faster than 1600MHz with a cl9 timing does not offer any noticeable improvement in gaming performance?

    In that case, I'll be getting a 16GB kit.
