DDR3 1600 or 1333?

Hi, im a bit confused with the memory timing is a 1600 at 9-9-9-24 is beter that a 1333 at 7-7-7-21?

  1. 1600 at 8-8-8-24 is even better than both...

    Are you overclocking ? You didn't give many system specifics but at "stock", a 920 is at:

    133 x 8 mem multiplier = 1066 Mhz
    133 x 20 CPU multiplier = 2.66GHz

    167 x 8 mem multiplier = 1333 Mhz
    167 x 20 CPU multiplier = 3.33GHz

    200 x 8 mem multiplier = 1600 Mhz
    200 x 20 CPU multiplier = 4.00GHz

    If you wanna OC to 4 Ghz, yes 1600 is better..... If you wannna OC to 3.33 Ghz, yes 1333 just as good.

    After that, lower timings are better.
  3. sorry i am new here can you explain what those numbers means ???

  4. esa,

    the 1600 is the ram frequency (1600MHz) and the 8-8-8-24 is the CAS timing. from wiki:
    Column Address Strobe (CAS) latency, or CL, is the delay time between the moment a memory controller tells the memory module to access a particular memory column on a RAM memory module, and the moment the data from given array location is available on the module's output pins. In general, the lower the CAS latency, the better.

  6. i saw an article once giving uite a good analogy. it was a bit like this...

    imagine the ram as cars, the 1600 mhz can go faster, but with a higher latency, has to drive further

    whereas the 1333 is slower, bu with lower latency doesnt have to go as far.

    i picked up some 1600mhz ram with 7-7-7-something. i have a cheap cooler on the ram and have it overclocked to 1800 mhz. it scores 7.9 wei in win7.

    you neednt worry about it costing a bomb either. my 6gb was £94 off ebay. which in the uk is very cheap.
