Please help 1333 CAS7 vs 1600 CAS9

Hello,
I have tried to find the answer to my question for several hours and get conflicting opinions. I am trying to figure out which would be better ram for my system. I have a z68 mobo and will mostly be using the computer for gaming, HD video watching, surfing the web and downloading. I have decided to go with 8GB as I have read around here that it improves gaming over 4GB. My choices in my budget are:

1333 at CAS 7
1600 at CAS 9

Which would you suggest? Both are the same price.

  1. it depends what frequencies does your system support. Since it is the same amount of money I would definitely go for the 1600MHz which is obviously faster!

    Well it supports up to 2133. I have heard some people say the higher frequency is better but others say the lower Cas Latency is better. So the 1600 is faster even though the Cas latency is 9 vs 7 on the 1333?

    Sandybridge architecture only have real gains up to DDR3 1333mhz. Anything above this would have only impact in some synthetic specific memory benchmarks.

    Go with the 1333 CAS 7

    (If I'm not mistaken only the AMD Llano and FX lines uses up to 1866mhz natively)

    Yeah I kind of figured I wouldn't see any difference other then in benchmarks with 1600 over 1333. Would that be the case with CAS latency as well?
  5. Go for the lowest CAS. DDR3 is fast at any frequency. Even 1066 is pretty good. Everything above 1333 is useless IMO.
  6. Look at your Motherboard Memory QVL, there are always better choices,
    I found a CL7 2000mhz memory module, and it actually ran at 2000mhz, with 7-8-7-24
    I tried the same thing on my PC, though,
    in CL7 1333mhz vs CL9 1600mhz on a cheaper module I noticed that,
    battlefield 3 had very less hitching while changing from iron sights/scope to normal view.
    In this scenario, I am inclined to believe more means better.
  7. Any more opinions on this before I make a purchase? Does 8GB Really make a difference over 4 for gaming?
