    HI, i am going to be upgrading the RAM in my Sager JFL92, i have DDR2 at 333Mhz in it right now, and using CPU-z and Speccy i can only find out the CURRENT RAM speed. now, i know it can handle faster than 333mhz, how do i determine what it can handle? my CPU is a t9300 2.5Ghz Dual Core.

    please help me figure it out or if you just know it'd be much appreciated :)

    How do you know it can handle faster than that? Your memory is actually DDR2-667 and most likely is limited by the chipset.

    Everest(Trial Version) can show the speeds that the chipset supports.

    it says the RAM that is in there is
    "Max Bandwidth PC2-5300 (333 MHz)"

    so i assume since that is awfully slow compared to 667 and 800 that are out there for DDR2 that it can atleast handle something faster. and how do i determine what the limitation of the chipset is? is there something else i can look up?

    would i not see a difference going from 333 to something like 667 or 800? or is it pointless?

    PC2-5300 (DDR2-667) means 667MHz ram. Seeing 333MHz is normal (it's 333Mhz x 2 = 667MHz) since it is DDR2 in dual channel. You will not see much of a performance gain going from 667 to 800.

    click in Everest "Chipset(=Chipsatz)" and you will get the supported speeds
    example is from a german version

    Covert Death it is as aylafan says and if fact I will go futher and say you will see zero performance gain upgrading to pc6400 memory (800 mhz ) from your current 667 mhz ram.

    In fact where overclocking is concerned you would actually lose performance. The reason for this is faster memory "supports" faster speeds as a result if you overclock your cpu beyond its normal 667mhz speed the 800mhz ram would use slower memory timings. You are better off therefore using 667mhz so that even if you overclock the memory timings will stay the same and won't get slower. I for example went from 4gb of 800mhz ram to 8gb of 667mhz ram for this reason and also because it was cheaper.

    Stick with what you have.

    even with machines that have pcix connect solid-state mass storage, the machine will always be bottlenecked by the ssd or hdd.

    putting money or effort into trying to speed up a cpu, memory or even gpu is nothing compared to system improvements that can be made with fast mass storage.

    it's a dirty little secret.

    fast mass storage is expensive. and most people will buy their machines based on cpu clock or some nonsense like that.
