Elpida Memory?

  1. Hey guys,
    I just noticed my Alienware Aurora has 6GB of Elpida DDR3 RAM. Elpida seems to be a very small and unknown company, does anyone know how it compares to say, Corsair Dominator or Dominator GT? Thanks!

    Elpida are actually a large company that specialise in manufacturing memory chips for other companies. Elpida's Hyper IC is are the memory chips under the Dominator GT DDR3-1600/-1866/-2000 heatspreader. All Corsair tri-channel kits (XMS, Dominator, Dominator GT DDR3-1333 to
    DDR3-2133) for example use Elpida IC's for version 2 of the modules ( v1 is Qimonda, v3 is Micron, v4 is Samsung, v5 Hynix, v6 Promos, v7 PSC, v8 Nanya, v9 unused at present)
    Elpida's J1108BASE-MNH-E HYPER 08470WP3T are used in A-Data DDR3-2133X
    while their J1108BABG-DJ-E is used on their own brand DDR3-1333 as well as Apacers,
    their J1108BASE-DJ-E is used on Kingston DDR3-1333
    J1108BBSE TWN is used on Mushkin Redline DDR3-1600

    Elpida, like other memory IC makers, "speedbin" their products -seperating the IC's into groups by bandwidth (speed) and latency. DDR3-1333C7 for instance is comparable regardless of RAM module manufacturer-the only selling point is extra packaging (heatspreaders, tall heatsinks, fan kits, liquid cooling kits...all bling, unless you plan on doing some serious overclocking.)

    Thanks! I have Elpida's PC3-8500. How powerful is this?

    Your DDR3-1066 is about as "powerful" as any other DDR3-1066 RAM.
    PC3-8500 refers to the peak transfer rate (8533 Mb/sec)- the higher the number, the higher the bandwidth (transfer rate).
    This is bound with the latency (C, CL or CAS number is usually quoted on the RAM) the lower the better. In basic terms it is the number of cycles between input of information to the output of data.
    The highest possible bandwidth (transfer rate) allied with the lowest possible latency is the best combination, although in actual real-world use there would be little to distinguish between DDR2-800 CAS4 and DDR3-1333 CAS9. Benchmarks such as SuperPi would show tangible differences but you would not notice these differences in day-to-day computer usage.
    Lowering the latency on high bandwidth RAM (i.e Mushkin 998728 Redline DDR3-1866, CL7-7-6-20) however would be noticable in most software applications but attracts a very large price.

    There's a reason that RAM kit reviews aren't plentiful on the net. It's because at a given speed and latency they all perform virtually the same. The only difference is how well they overclock at a given voltage or how tight their timings can be brought in, and like overclocking CPU's and GPU's will differ in every case.

    RAM is so common it is actually traded as a commodity.
