LGA 1156 Memory Performance: What Speed DDR3 Should You Buy?
By

We used the Asus Maximus III Formula, a high-end P55 motherboard, and an Intel Core i7-870 processor to analyze memory performance.

To be able to set all described memory clock speeds and timings, we grabbed two Corsair CM3X2G1600C9DHX Dominator DIMMs. These are specified for DDR3-1600 speed at CL9 timings, but they can also run at CL8 settings. Keep in mind that all other system parameters, such as the processor speed, remained unchanged for the sake of consistency.

    I think the advantage of DDR3-1600 is not in the memory speed, but that the multiplier-locked CPU can be overclocked to a much higher frequency than DDR3-1066 would permit. This will result in the tremendous performance gain of DDR3-1600 over DDR3-1066.

    I love DDR3! It's such fast ram and mine is only 1333mhz. Well worth the upgrade from ddr2.

    Thanks a lot guys,that was a usefull guide if you are wondering what memory you will get.Why are you showing all the benchmarks in percentages?
    in the games,mp3 encoding,rar?you could give us a precise result by showing it on fps,minutes and secs,scores,etc.it doesn't really help if you say "Percent(more is better)".not offence,just trying to help.
    I took your advise anyway.Thanks

    Great, I'm still torn between lots of DDR3 brands for my next i5 750 / PII 955 builds, clearly that the difference between each RAM speed is not that much..so I'm going for the cheaper ones!

    Apart from my supplier not haveing a few of the compared items for sale, this was great help in deciding, thanks!
